Overview
A cataract is an eye disorder in which the normally clear lens of the eyes becomes cloudy. For people with a cataractous lens, seeing things feels like they are looking through a frosted or fogged-up window. Clouded vision can make reading and driving very difficult. It can be corrected by performing cataract surgery.
What Is Cataract Surgery?
Cataract surgery is a surgical procedure used to treat the condition of cataract. In this surgery, the cloudy lens of the eye is removed with an advanced ultrasonic laser and replaced with a foldable artificial lens.
How Is Cataract Surgery Performed?
- It is done as a day care procedure. It takes about 20 – 30 minutes to complete this surgery.
- An eye drop is administered to your eye to dilate the pupil.
- Topical anaesthesiai.e simple anaesthetic eye drops are used to numb the eye
- In rare cases, Local Anaesthesia may be used
- General Anaesthesia is not required
- An ultrasound probe is used to clean up and aspirate the cloudiness of the lens
- Then the clouded lens is aspirated, and a new clear artificial lens is placed into the eyes.
- This is a safe and painless procedure,
Surgical methods used to remove the cataract surgery are:-
- Making a small incision in the eye and removing the cataractouslens in one piece: This is a less commonly used method. It requires a slightly larger ( 5.5mm ) incision. The lens is removed as a whole part through this incision. Only the outer capsule is removed, but the inner capsule is left in place. This inner capsule act as a support for the artificial lens to rest.
- Using ultrasound energy for removing cataract: In this procedure, a micro (very tiny) opening is made into the eye. Aultrasound probe is inserted through this. Then, the cataract is broken using ultrasound, and then aspirated using the suction.
This being a microincision procedure, it requires no stitches or no injection.
