Surgery & Post Operation Vision Correction

What is Cataract?

Cataract is the clouding or opacity of the eye’s crystalline lens, usually develop slowly and don't disturb your eyesight early on.  It is the most common eye disease.

The cataract appears as light milky opacification within the pupil.

Most cataracts develop when aging or injury changes the lens cell structure or/and protein constituents. Some inherited genetic disorders that cause other health problems can increase the risk of cataracts. Cataracts can also be caused by other eye conditions, long tern use of steroid medication, intraocular eye surgery or medical conditions such as diabetes.

At first, stronger lighting and eyeglasses can help deal with vision changes resulted from cataracts. Surgery is the only effective treatment when one’s visual function has deterioration and affected daily activity or the cataract is causing ocular complication such as glaucoma.

Preventions include stop smoking, manage diabetes or other medical conditions that can increase the risk of cataracts, choose a healthy diet that includes plenty of fruits and vegetables, protect eyes from UV rays, excessive alcohol use can increase the risk of cataracts.

Cataract surgery usually performed on one eye, the fellow eye may not need same surgery for short or long time to come.


After cataract surgery, the operated eye often requires some degrees of refractive correction with spectacle, as a "top-up" to optimise distance or near visual function. For instance, some patients complained of cannot see things at near clearly after cataract surgery but could do so before the surgery.

If you are wearing spectacle with moderate to high degree power before cataract surgery, regardless the type of intraocular implant (IOL), whether monofocal, multifocal or extended focus lens implants, used in the unilateral cataract surgery. After the surgery, you will likely experience symptoms of uncomfortable vision, such as disorientation, confusing or seeing double images (diplopia) with two eyes as a result of different retinal image sizes in two eyes (aniseikonia) and/or differential prismatic effect induced from the new spectacle lenses.
