The human crystalline lens, which is clear and transparent, is part of the focusing mechanism of the eye. With age, the lens becomes cloudy and opaque, thereby hampering normal vision. Any opacity in the crystalline lens, which leads to decreased vision, is cataract.
CAUSES OF CATARACT
Ageing is the most common cause. With age, proteins of the eye lens get altered and opacified leading to cataract. Other causes include congenital and developmental anomalies, trauma, inflammation of the eye, metabolic diseases like Diabetes, Hypothyroidism etc.,
WHAT ARE THE SYMPTOMS OF CATARACT?
WHAT ARE THE TREATMENT OPTIONS AVAILABLE?
Surgery is the only course of treatment for cataract. There are two options available for cataract surgery.
SMALL INCISION CATARACT SURGERY
MICROINCISION CATARACT SURGERY (PHACOEMULSIFICATION)
In some cases, the patient is able to see almost immediately following the surgery, although most patients experience clear vision after one or two days
NEED FOR GLASSES AFTER SURGERY
You may need to wear glasses only to fine -tune your vision. These spectacles have normal lenses unlike thick lenses used in the past. If unifocal IOL is used, near vision glasses are almost always required.
ACTIVITIES TO BE RESTRICTED AFTER SURGERY
Normal activities including reading, writing, watching television etc. may be resumed soon after the surgery. However, during the first week after the surgery, it is better to avoid strenuous activities & avoid exposing the eye to water or dust.
DURATION OF THE PROCEDURE
With the advanced technique of the cataract surgery, removal of the cataract takes just about 2-5 minutes and the entire procedure would take about 15 minutes.
MULTIFOCAL IOL/ACCOMMODATIVE IOL :
The regular intraocular lenses are designed for distance vision. After cataract surgery patient has to wear glasses for reading. The latest multifocal IOLs are designed to provide good distance vision, intermediate and near vision. They reduce the patient's dependence on glasses for routine activities. Unlike conventional IOL it has multiple zones of different focal lengths that bring everything from near to far into clear focus. These lenses can be used only for suitable patients.
We have specialists who are experienced with latest technique of phacoemulsification with foldable IOL implantation.
