Our clinic operates from 9:30 AM to 9:30 PM, every day of the week. Please call us before you come.
Q6I am 17 years old, can I have a cataract?
It is not common but possible. Usual causes are genetics, tuberculosis, and diabetes.
Q7My father has a cataract, can it be treated without surgery?
Unfortunately, cataract can only be treated with surgery. The good news is that it is an elective surgery.
Q8Is orbital cellulitis a vision- or life-threatening condition?
Orbital cellulitis can be vision-threatening, and if not treated early, can become life-threatening.
Q9I have a headache starting from my eye and I am unable to sleep, what could this be?
These symptoms are probably migraine-related. Keep a disciplined routine and take regular medicine as advised by your doctor.
Q10What are the charges for cataract surgery?
The starting price is PKR 45,000, and can range up to 100,000 and above, depending on various factors.
Q11I am a carpenter and I have a headache and difficulty sleeping, is this due to my eyes?
Headaches caused exclusively by eye problems are less likely. Please also work on improving your sleep.
Q12My child had an eye injury and the doctor says he has hyphema, what is hyphema?
Hyphema is blood in the anterior chamber of the eye. Mild cases resolve with drops; otherwise it needs drainage by an eye surgeon.
Q13I have severe asthma and cannot lie down for long, how will I be operated on for a cataract?
After you take your asthma medication, our cataract surgery at Ismail Eye Surgery takes around 10 minutes, and we keep you in a tilted position with your head slightly raised.
Q14I had cataract surgery in one eye 4 years ago, is it a good time to get the second eye operated on?
You are actually a little late. If you are healthy and mobile, do not wait for another reason to stop you from getting your eye surgery. We are among the best eye specialists in Faisalabad.
Q15What is iris coloboma?
Iris coloboma is a small defect in the coloured part of your eye. It may be associated with other defects in the eye as well.
Q16(Translated) May the peace, mercy, and blessings of God be upon you. اَلسَلامُ عَلَيْكُم وَرَحْمَةُ اَللهِ وَبَرَكاتُهُ
Hope you are well. I was wondering if I could find out about natural lens replacement surgery. I have +6.50 astigmatism in my right eye and +5.25 in my left eye.
It would be better if you book an appointment. It seems you need a toric IOL.
Q17Why is my eye red after cataract surgery, though my vision is okay?
If your vision is okay, you do not need to worry. Mild bleeding is common after cataract surgery and usually resolves within a week.
Q18I am 50 years old and was diagnosed with diabetes yesterday. I see a fly-like thing in my left eye, what should I do?
You should control your sugar and see an eye doctor for a fundoscopy.
Q19How do I know if I have glaucoma?
Your eye pressure (IOP) can be high, your cup-to-disc ratio can be asymmetric and increased, and visual field loss confirms the diagnosis of glaucoma.
Q20I had a corneal abrasion and the doctor prescribed some drops, my vision is blurry after these drops, why?
Your vision is probably blurry due to cycloplegic drops. Once you stop these drops on your doctor's advice, your vision will improve.
Q21Do you use AI as a tool or as an alternative to a human at Ismail Eye Surgery?
We use AI as a tool and keep a human in the loop, meaning AI expands what we can do, while a human always makes the final decision.
Q22My son is 6 years old and needs cataract surgery, what type of anaesthesia does he need?
This surgery is done under general anaesthesia at Ismail Eye Surgery.
Q23I have diabetic retinopathy in both eyes, and one eye is affected more than the other. What is the single most important thing I should be careful about?
Patients with diabetic retinopathy should control their sugar and keep their HbA1c at around 6.
Q24Can a simple viral eye infection decrease my vision?
Yes, it can. Conditions such as corneal ulcer, uveitis and keratitis can all lead to decreased vision.
Q25Can you treat retinitis pigmentosa?
We manage retinitis pigmentosa. The vision loss is gradual, and we cannot stop that. There are some associated conditions with retinitis pigmentosa that we also have to treat, such as cataract.
Q26I have keratoconus and had CXL done. I am 20 years old, can I get rid of glasses?
It depends on your motivation. As far as a surgical option is concerned, an ICL would be an option to help you become glasses-free.
Q27What is eye replacement surgery?
It refers to cornea replacement surgery. The cornea is the front-most part of the eye. If the remaining parts of the eye are working fine, the cornea can be replaced with a healthy cornea from another person. This is usually called eye replacement surgery.
Q28Why did my father's eyesight decrease 2 months after cataract surgery? He did not stop smoking and is diabetic.
Uncontrolled diabetes and smoking are risk factors that can damage critical parts of the eye, such as the retinal vessels and optic nerve. In your father's case, the optic nerve has likely been damaged due to uncontrolled sugar and continuous smoking.
Q29Why am I unable to see hair while doing hair-removal laser on my patients?
You are showing symptoms of presbyopia. You need near glasses while performing laser procedures on your patients.
Q30What can be done if my mother has a prescription of +3 sph and -4.0 cyl after cataract surgery?
Most probably she is “undercorrected” and needs an IOL exchange surgery. Undercorrection means her lens power in the first surgery was lower than what she actually needed.
Q31My uncle had retina surgery in the right eye due to uncontrolled diabetes and his vision in that eye is still not good. Different clinics have given different opinions, and some even call it glaucoma. His HbA1c is 12, what should he do?
Retina problems usually have limited success even after surgery, since the retina is a thin layer at the back of the eye that gets damaged by uncontrolled diabetes. His vision in the right eye is unlikely to improve with glasses. Many people label this as glaucoma because the optic disc can turn pale after the PRP laser done during retina surgery. What he needs to do is control his sugar, so he can protect the vision in his other eye and live independently.
Q32Are you the best hospital for eyes?
We are among the best eye hospitals in the area, and we have integrated partners locally and internationally.
Q33Is eye surgery 100% safe?
If you are asking about refractive surgery compared to the past, it is very safe now. Patient selection is key in every eye surgery, the right surgery for the right patient. Cataract surgery has many challenges, for example uncontrolled diabetes is one big factor. Similarly, in glaucoma surgery patients usually decide late and should have realistic expectations. Squint surgery usually has a good outcome, as does ptosis surgery. Retina surgery has more limited results, although it can still save patients from going blind.
Q34How long after my mother's cataract surgery will she need drops and oral medication?
Usually it is just drops, used for 3 to 4 weeks. Some patients might need oral analgesics right after surgery. In other cases, your doctor can decide on your particular need for oral medicine.
Q35My mother is 70 years old, what is the right time for her to get cataract surgery?
As we age, the challenges do increase, and sometimes the thought of adding another appointment or procedure to the list feels overwhelming. But here is the crucial truth: the right time for cataract surgery, for patients like your mother, is today.
Q36Can Ozempic (semaglutide) for diabetes and weight loss also affect the eyes?
The European Medicines Agency (EMA) has recently reviewed the safety of semaglutide medicines such as Ozempic, Rybelsus, and Wegovy. Their safety committee (PRAC) concluded that these medicines may very rarely cause an eye condition called non-arteritic anterior ischemic optic neuropathy (NAION), which can lead to sudden vision loss.
Q37I had CSR, and the fluid under the NSR (neurosensory retina) has resolved, but vision loss remains. Can I take creatinine?
CSR is an idiopathic inflammation of the choroid, so it is good news that the fluid under the NSR has resolved. If vision has not improved, one possible reason is that some fluid may still be present. Creatinine will not help improve the vision.
Q38Is there any latest technology to stop white motiya (cataract)?
There are some rumours of drops that dissolve cataracts, but nothing concrete is available in the market yet. Even if such drops existed, the space would still need to be replaced with an artificial lens. If you have diabetes, hypertension, or are taking steroids, good control of these conditions will slow down cataract formation.
Q39I was recently prescribed Brimonidine drops to help with some night-time issues, but they don't seem to help. Could my issue not be pupil-size related? I'm worried corrective lenses won't help either.
Brimonidine is not typically used for pupil size control; it is mainly used to lower eye pressure (IOP). If anything, it can dilate the pupil further and worsen photophobia. Brimonidine acts on the alpha-2 receptor in the iris and ciliary body to lower IOP. If your doctor were trying to constrict your pupil at night, an alpha receptor agonist would only dilate it further. You would need pilocarpine, an M3 receptor agonist, to constrict the pupil and possibly help your symptoms. Please discuss this directly with your doctor.
Q40I have a similar condition (large exotropia), what should be done for it?
Surgery is typically considered when the deviation is large, frequent, or affects vision and quality of life.
Q41Should I get LASIK with -7.0 myopia and 480-micron corneal thickness?
No, you will likely regret it. The cornea is already thin, and operating on it can lead to corneal ectasia or regression.
Q42My 80-year-old father has advanced-stage glaucoma in one eye. He has tried all eye drops and SLT before, and they stop working after a few years. Doctors now recommend trabeculectomy with cataract removal in that one eye. Is there a reason not to do it?
Doing it is a wise option. It will help keep him independent. Otherwise, he will become completely dependent. He deserves to have all the available options considered.
Q43I had a Clareon PanOptix IOL placed in my left eye. Since the eye shield was removed I have blurry vision, flickering, and it feels like I can see the edges of the lens. The surgeon says it's normal, but I'm worried it won't go away.
Thanks for sharing your experience. Since it has only been two days after your surgery, it is normal to feel some discomfort. What you are describing, the edge effect and “seeing the IOL”, is something we don't usually hear this strongly with monofocal IOLs. PanOptix is a premium lens with mires built into its design, and when light hits those, some patients feel uncomfortable, which is why dim lighting helps in the early days. If you are physically active and work regularly, these symptoms may feel more noticeable, even with 20/20 vision. Please give it at least 2 weeks before judging the final outcome. If after 2 to 3 weeks you still don't feel comfortable, switching to a monofocal IOL can be discussed with your surgeon.
Q44I had cataract surgery this year in both eyes with a standard IOL. My optometrist recently noticed a secondary cataract forming in the right eye. I'm 69 with no history of retinal issues or glaucoma.
This is most likely PCO (posterior capsular opacity), or in some cases remnant cortical matter from the previous surgery. In either situation, the best person to advise you would be the surgeon who performed your original surgery; a second opinion from another surgeon is also reasonable. PCO is treated with a capsulotomy, and the IOL can be exchanged afterwards if needed. Please don't worry.
Q45Can someone help me understand the usefulness of the Humphrey visual field test, especially for early detection, given it only tests the central 24 degrees while the normal visual field is much wider?
No single test is 100% reliable on its own. A combination of visual field testing and OCT RNFL helps a doctor detect glaucoma early. Central vision is tested because we rely on it for almost all everyday function, while peripheral vision mainly supports spatial awareness, position relative to other objects, and related functions.
Q46I just had SLT done. My pressure was 22 afterwards, close to my pre-treatment reading of 23. Will it go down more? I'm also still using brimonidine until my follow-up.
It is common for pressure to take some time to settle after SLT, and your doctor will assess the full response at your follow-up visit while you continue your current drops. SLT works by opening the eye's drainage meshwork, but it does not work equally well for every patient. Please continue attending your follow-up visits so your doctor can track the trend over time.
Q47My LASIK surgeon reacted strongly to me moving during surgery, and my right eye now has worse glare, halos and a foreign-body sensation than my left. I feel awful about it.
In our experience, a surgeon may react firmly when a patient makes a sudden, unexpected eye movement at a critical step of the surgery, since that moment carries real risk. Experienced surgeons prepare for this possibility and usually manage it well. It helps to build a good rapport with your surgeon and to follow their advice closely going forward, keeping in mind that both patient and surgeon are human.
Q48I am 35 years old with a cataract in one eye. How can I be glasses-free after surgery?
The best option is usually a multifocal or extended-depth-of-focus (EDOF) IOL. This can help you become glasses-free after surgery.
Q49I'm getting married in 10 days, can I temporarily correct my squint (exotropia) with a lens or any other means for photos?
Congratulations on your wedding, and we understand your concern. No lens can temporarily correct exotropia. What you can do is ask your photographer to avoid angles and close-up shots where the squint is most noticeable.
Q50My glasses number is +7, can I get refractive laser surgery?
Unfortunately, you are not an ideal candidate for refractive laser surgery. However, small or high-power eyes can be offered an EDOF or multifocal IOL after a thorough workup and discussion.
Q51Can amblyopia be treated after the age of 20?
If you have already undergone amblyopia therapy and it did not work, further improvement is less likely. That said, a trial of therapy can still be planned at any age.
Q52I have strong myopia and underwent phaco surgery. Afterwards my eye pressure increased and damaged my optic nerve. My pressure is now stable at 13 with drops, but my vision keeps declining. What should I do?
I think you need a proper trabeculectomy with MMC. A target IOP of around 7 to 8, or lower, may help preserve your remaining vision.
Q53How often should an adult with amblyopia that wasn't treated in childhood have their eyes checked, to avoid complications?
There is no single fixed interval, but a check-up every 6 to 8 months is generally a reasonable schedule.
Q54My wife had PanOptix Pro done in her first eye, with "diagonal light sabers" across bright lights, sparkles, and a dark shadow on one side. She is worried about her second eye, which is already scheduled.
A monofocal IOL is usually the safer option in a case like this. It's reasonable to avoid further experimenting with premium lenses given her experience so far.
Q55When I was 13, an OCT macula test showed a problem in the macula. I'm now 18 and getting checked again. What could be the cause and what is the treatment?
Before discussing treatment, the most important step is to confirm the correct diagnosis. Most macular disorders have limited treatment options, and management is usually supportive rather than curative.
Q56I am 22 and had cataract surgery at age 2. I now have almost +10 glasses in both eyes, a weaker left eye, and nystagmus. Can I become glasses-free?
It's likely you have small eyes, and performing an IOL exchange in such an eye carries real risk. I would recommend a conservative approach and would not advise further surgery, especially since you rely mainly on one functioning eye.
Q57Can a retina be transplanted?
To date, a detached retina can only be reattached, and even that surgery has limited success; a retina cannot be transplanted. Some experimental devices with external sensors are being trialled to help fully blind patients navigate, but this technology is not yet widely available.
Q58I have commotio retinae (retinal swelling from trauma), will anti-VEGF treatment work?
Anti-VEGF treatment does not work for commotio retinae.
Q59What are bio-optic glasses, and can they be used in Stargardt's disease?
Yes. Bio-optic glasses are essentially built-in telescopes, special magnifying devices used to enlarge the image for patients with reduced central vision.
Q60Which vitamin is good for optic nerve health in advanced glaucoma?
Nicotinic acid, or niacin (vitamin B3), is considered beneficial for optic nerve health.
Q61Does congenital maculopathy cause blindness?
Usually it is not fully blinding, but teachers, parents, peers and everyone around the affected person should be supportive, as they have to live and function with it long-term.
Q62How do you treat retinoblastoma?
Treatment depends on the stage and grade of the tumour.
Q63What are neuroprotective drops in glaucoma?
Neuroprotective drops help safeguard retinal ganglion cells while also reducing IOP. Among them, alpha-2 adrenergic receptor agonists lower aqueous production and may offer additional optic nerve protection, because preserving vision means protecting the nerve, not just controlling the pressure.
Q64What is the Boston keratoprosthesis?
In selected cases of corneal blindness, the Boston Keratoprosthesis can restore vision when standard corneal grafts are not suitable. It is a specialised device that must be specially ordered and is not readily available.
Q65I have a squinted eye due to Duane syndrome, can it be corrected with surgery?
This condition is mainly managed or treated non-surgically.
Q66My 35-year-old son has pain on eye movement along with a sudden decrease in vision in one eye, what could this be?
A young patient with sudden vision loss in one eye plus pain on eye movement should raise suspicion of optic neuritis. Early treatment with 3 days of IV steroids followed by 7 days of oral steroids can shorten the recovery time.
Q67Do you provide online consultations?
Yes, we welcome online consultations. Message us on WhatsApp at +92-321-7825861 and we will walk you through the process.
Q68Are punctal plugs used in all dry-eye patients?
No. Punctal plugs are typically used in specific cases: aqueous deficiency (for example Sjogren's syndrome) to retain tears, severe dry eye to reduce drop use, post-LASIK dryness for temporary support, contact lens-related dryness to improve tolerance, and neurotrophic cornea to help maintain moisture.
Q69Can cataract surgery be done in a patient with nystagmus while awake?
Yes. Nystagmus is not always a barrier to cataract surgery, and selected patients can successfully undergo the procedure under topical anaesthesia.
Q70Should I go ahead with trabeculectomy for my 85-year-old mother? She has normal tension glaucoma (NTG) with myasthenia gravis (MG) and other health issues.
This is a difficult, finely balanced situation. 85 is a late age for trabeculectomy, since post-operative care requires multiple visits. Ideally it would have been done 20 to 25 years earlier. Her mobility is also already limited by MG. In a fragile situation like this, you are unlikely to get the best outcome from any procedure unless it is truly sight- or life-saving.
Q71Does SLT ever work better the second time?
If the disease is progressive, please consider trabeculectomy with MMC. Newer options like stents and SLT are mainly useful in the earlier stages of disease. If the condition has already been present for around 20 years, repeating a lower-impact option may not make sense; a more definitive procedure is usually the better path forward.
Q72Why is my eye red after squint surgery?
The redness is completely normal and is caused by temporary mild bleeding under the conjunctiva (subconjunctival haemorrhage) from the surgery. It will gradually fade over the next few days to weeks, and using the prescribed eye drops regularly will help soothe the eye and speed up recovery.
Q73Can all of these eye tests be performed at Ismail Eye Surgery?
Yes. We offer a comprehensive eye evaluation that may include an optic nerve examination, OCT RNFL, retina and macula examination (after pupil dilation), and a visual field test where indicated.
- Optic Nerve Examination
- OCT RNFL
- Retina/Macula Examination (after pupil dilation)
- Visual Field Test (if indicated)
Please arrive 10 to 15 minutes before your scheduled appointment. If your pupils are dilated, you may experience temporary blurred vision, so bringing an attendant is recommended.
Q74I am 21 with asthenopia (eye strain) and anisometropia. Are these two conditions related? Also, why does my lazy eye sometimes drift outward?
Asthenopia (eye strain) and anisometropia are generally not directly related. Asthenopia refers to symptoms such as eye fatigue, discomfort, or headache after prolonged visual tasks, while anisometropia means there is a significant difference in refractive power between the two eyes. If a lazy (amblyopic) eye occasionally turns outward, prolonged near work and long hours focusing on close objects can contribute to this. During extended near tasks the eyes may temporarily lose binocular coordination, a phenomenon called dissociation, allowing the weaker eye to drift outward. This can become more noticeable when you are tired, concentrating for long periods, or not actively using both eyes together.
Q75What is reverse hypopyon?
Reverse hypopyon is the accumulation of emulsified silicone oil in the upper part of the anterior chamber after vitrectomy surgery with silicone oil tamponade. Because silicone oil is lighter than the aqueous fluid, it floats upward and collects beneath the upper eyelid, giving the appearance of a "reverse hypopyon." In some cases, especially if it causes increased intraocular pressure, corneal damage, or significant symptoms, it may need to be removed by an eye specialist.
Q76I am 19 and was diagnosed with traumatic optic neuropathy after a road traffic accident. I have lost vision in one eye and my MRI has been done. Is there any chance my eyesight will return?
Traumatic optic neuropathy is a serious injury to the optic nerve caused by trauma. Unfortunately, the visual prognosis is generally poor, especially when there is severe optic nerve damage. Even a completed MRI cannot guarantee vision recovery. In many patients the optic nerve gradually develops secondary optic disc pallor (optic atrophy), indicating permanent nerve damage, which means significant visual recovery is less likely in most cases.
Q77I am 34 and have Stargardt's disease. Where can I get optical help or low-vision aids in Faisalabad?
Patients with Stargardt's disease may benefit from a low vision assessment and appropriate visual aids. In Faisalabad, you can visit the Low Vision Aid (LVA) Department at Allied Hospital-I (near Sargodha Road) or Madina Teaching Hospital (Sargodha Road) for assessment and guidance on suitable low vision devices.
Q78I am a glaucoma patient. Should I choose a multifocal IOL for my cataract surgery?
Multifocal IOLs may not be the best choice for glaucoma patients. Glaucoma can reduce contrast sensitivity and visual quality, and these problems may become more noticeable as the disease progresses. In many glaucoma patients, a monofocal or other carefully selected IOL is the safer choice.
Q79Can vaping or smoking weed make glaucoma worse?
Smoking and vaping expose the body to harmful chemicals and oxidative stress, which may adversely affect the optic nerve. However, current evidence does not conclusively prove that cannabis or vaping directly accelerates glaucoma progression independent of IOP. The most important modifiable factor remains good IOP control and regular glaucoma follow-up.
Q80Which IOL formula is best if I've had LASIK and now need cataract surgery?
Previous LASIK makes IOL calculation more challenging. If using an IOLMaster, commonly preferred options include Barrett True-K or Haigis-L/True-K based calculations, depending on the available measurements and software. Whenever possible, comparing multiple modern formulas is better than relying on a single calculation.
Q81Can an extruded Ahmed Glaucoma Valve be reimplanted?
No. Once an Ahmed Glaucoma Valve has extruded from the eye, it is generally not suitable for reimplantation because of the risk of infection and contamination. If glaucoma treatment is still required, your ophthalmologist may consider alternative surgical options.
Q82How does Ozempic affect my vision?
Ozempic (semaglutide) has been associated with a risk of non-arteritic anterior ischemic optic neuropathy (NAION), which can cause sudden vision loss. We recently saw a patient on Ozempic with sudden vision loss, where the visual field and OCT RNFL findings pointed toward a neurologic cause. If you are taking Ozempic, it's worth remembering that it is not without possible effects on the eyes.
Q83What is the treatment for a conjunctival cyst in a 7-year-old child?
For a large conjunctival cyst, particularly a conjunctival inclusion cyst, imaging may be recommended to determine its size and extent. Treatment is usually marsupialisation or complete surgical excision, depending on the size, location and characteristics of the cyst. Simply aspirating or draining the cyst with a needle may not remove its epithelial lining, so the cyst can recur.
Q84How can shingles affect my eyes?
Shingles affecting the eye can cause severe inflammation inside the eye (vitritis) and, in aggressive cases, retinal necrosis. Retinal involvement can have a poor visual prognosis and requires urgent ophthalmic assessment and treatment.
Q85What is the use of systemic antiviral therapy in acute retinal-necrosis due to varicella zoster viral infection?
Reference: Kanski Vol. VII, page 445.
It will increase the resolution of acute retinal necrosis in the effected eye and reduce the risk of second eye (healthy eye) involvement. But it will not prevent retinal detachment (RD).
Q86What are the pros and cons of lens replacement surgery vs lasik after the age of 40?
Reference: Kanski,Elkington
| Feature / Criteria | Lens Replacement Surgery (RLE) | LASIK (Laser Vision Correction) |
|---|---|---|
| Primary Mechanism | Replaces the natural aging lens with a clear artificial intraocular lens (IOL). | Reshapes the outer corneal surface with an excimer laser. |
| Presbyopia & Near Vision | Directly treats presbyopia using multifocal, trifocal, or EDOF IOLs for distance, computer, and reading vision. | Does not reverse presbyopia. Requires Monovision LASIK (one eye distance, one eye near) or reading glasses later. |
| Future Cataract Risk | Eliminates future cataracts completely, as the natural lens is permanently removed. | Does not prevent cataracts. You will still likely need cataract surgery in your 60s or 70s. |
| Pros |
|
|
| Cons |
|
|
| Invasiveness & Recovery | Intraocular microsurgery; stabilization takes 1 to 4 weeks. | Extraocular corneal procedure; functional vision recovers in 1–2 days. |
| Ideal Candidates | Patients 45+ with presbyopia, high farsightedness, or early nuclear lens changes. | Patients aged 40–50 with strong distance vision needs, clear natural lenses, and good corneal thickness. |
Q87What is a bionic eye? How does the PRIMA retinal implant differ from the Argus II retinal implant?
| Feature | PRIMA Retinal Implant | Argus II Retinal Prosthesis System |
|---|---|---|
| Primary Target Disease | Advanced Dry AMD (Geographic Atrophy) | Advanced Retinitis Pigmentosa |
| Implant Location | Subretinal (Under the retina, replacing photoreceptors) | Epiretinal (On top of the retina, stimulating ganglion cells) |
| Power & Data Link | Wireless (Powered entirely by near-infrared light from the glasses) | Wired (Uses a physical cable connected to an extraocular electronics case) |
| Resolution (Pixels) | 378 pixels (Photovoltaic micro-photodiodes) | 60 electrodes |
| Visual Quality | Restores true form vision (reading letters, numbers, and words) | Restores light and motion perception (detecting shapes, doorframes, and motion) |
| Peripheral Vision | Preserves natural peripheral vision while adding central bionic vision | Designed for patients who are already completely blind |
| Zoom/Magnification | Features an integrated electronic zoom capability | No built-in electronic magnification |
| Current Market Status | Commercially launched in Europe (CE Mark); pending FDA approval in the US | Discontinued (Manufacture and new implants stopped by Second Sight in 2019) |
