Squint (strabismus) surgery is far more than simply moving an eye muscle. The outcome of the results is what matters the most it starts from the measurement of the amount of squint before the surgery. At Ismail Eye Surgery, we have prisms bars vertical and horzontal both are available which are used to measure the amount of squint.

Prism Cover Test

This test help us measure the exact amount of squint. This test is considered as standered when we measure the amount of squint. The prisms help uThe Prism Cover Test (PCT) is considered the gold standard for measuring the angle of squint. By using calibrated prisms during alternate cover testing, we can accurately determine the amount of ocular misalignment in prism diopters.

Information which we get from this test is :

Determine the exact amount of squint
This help us measure the constant vs variable squint
Help us determine which muscle to treat
Give us the most accurate results

If one is unsure about the results of the surgery repeat prism cover test should be done to be sure about the out come. Some times it is hard to decide which eye is dominant and which eye is recessive and PCT needs to be repeated in such conditions. As surgery is usually performed first on the recessive eye.

Right Measurement For The Right Results:

Successful squint surgery begins long before the patient enters the operating room. The surgical plan is based on prism measurements, ensuring that the amount of muscle recession or resection is tailored specifically to the individual patient.

Straight eyes, better eye alignment
Single vision
Best cosmetic look
Long term success and less need to do repeat surgery or other eye surgery.
