EYESIGHT TREATMENTS - CATARACTS

 

A cataract is an opacity [cloudiness] that develops in the lens of the eye or in its envelope. Age-related cataract may result in increased power of the lens, causing near-sightedness [myopia]. It can also lead to gradual yellowing of the lens; reducing the perception of blue colours. Untreated cataracts can cause vision loss and blindness.

Prevention & Treatment of Cataracts

Although there is no proven prevention of cataracts, wearing ultraviolet-protecting sunglasses may slow the development of cataracts.

Studies have also shown that regular intake of antioxidants (such as Vitamin Cand Vitamin E) may also be helpful.

For other cataract care products, including eye drops and vitamin supplements.

The most effective and common treatment for cataracts is to surgically remove the cloudy lens. More recent treatments for cataracts consist of a six-week period of eye drops.

Surgery For Cataracts

There are two types of surgery that can be used to remove cataracts:

  • Extra-capsular surgery [extracapsular cataract extraction, or ECCE] - removes the lens but leaves most of the lens capsule intact. High frequency sound waves [phacoemulsification] are sometimes used to break up the lens before extraction.
  • Intra-capsular surgery [intracapsular cataract extraction, or ICCE] - a rare procedure that removes both the lens and the lens capsule.

In both procedures, the lens is replaced with a permanent lens implant.

Recent improvements have resulted in a multifocal lens to create a visual environment in which they are less dependent on glasses.

Cataract operations are usually performed using a local anaesthetic, with the patient going home the same day.
