Cataracts

What are Cataracts?
A cataract is a clouding of the lens of the eye. Normally the lens is crystal clear as it serves to focus light onto the nerve layer of the eye. As a normal consequence of aging, the lens loses its clarity and becomes more or less hazy with time, like a window that has never been cleaned.


The most common symptoms of cataracts are:
- blurred vision
- difficulty reading
- glare, haloes and streaks from bright lights
- dull or dim vision
- occasional double vision

There are no pills or drops or other simple means to reverse cataracts. Cataracts can only be "cured" by cataract surgery.

Cataract Surgery
The only "cure" for cataracts is surgery, which involves the removal of the cloudy lens from the eye. There are a few different basic techniques and a number of subtle variations for the surgical removal of cataracts. By far the most commonly performed “state-of-the-art” procedure is phacoemulsification which involves the removal of the lens by ultrasound.

Once the cloudy “cataractous” lens is removed, the eye is left without this important focusing apparatus. Years ago, this lost focus power was replaced with very thick “cataract glasses” which markedly limited peripheral vision and caused an annoying magnification of images. Later, contact lenses improved things but it wasn’t until the late 1970’s when intraocular lenses (IOLs) were developed, that the replacement of the human lens became truly effective and practical. These lenses become a permanent part of the eye and do not cause any physical sensation.

The Toric IOL lens is recommended to patients who have both cataracts and astigmatism. The lens provides comprehensive vision correction to patients undergoing the surgery.
