Cataract Surgery
Cataract Surgery is a procedure that removes a clouded lens from your eye. In most cases the lens that is removed is replaced with an artificial lens. It is done when the clear lens on your eye becomes cloudy, blocking light from entering the eye and causing visual disturbances. The goal of cataract surgery is to restore clear vision.
Procedure Information
The cataract surgery begins with the administration of sedative or general anaesthesia. The surgeon will use a microscope to exam the eye and make a tiny incision. Then, they will remove the damaged lens.
The lens can be removed in one of two ways. The surgeon will remove it with a surgical instrument and suction, or they will use sound waves to break the lens up and then suction it. The method of removal depends upon the type of cataract you have.
Once the lens is removed the surgeon will place the artificial lens. The lens is called an artificial intraocular lens. After the lens is placed they will close the tiny incision they made with tiny sutures or self-sealing sutures.
Risks of the Procedure
As is with any procedure there are risks associated with cataract surgery. The following is a list of the most common risks and complications: reactions to anaesthesia or medication.
- Reaction to anaesthesia or medication
- Infection
- Incomplete lens removal
- Vision problems
- Additional surgery required
Glaucoma
Glaucoma is a disease that affects the major nerve of vision called the optic nerve. Glaucoma is characterized by a slow subtle loss of side vision (peripheral vision) that if not caught and treated properly can lead to blindness and loss of central vision. Glaucoma is usually associated with high pressure in the eye that eventually leads to blindness and loss of central vision. Glaucoma is usually associated with high pressure in the eye that eventually leads to the damage in the eye. It is the leading cause of irreversible blindness in the world. Glaucoma is more prevalent in individuals who are over 45 years old, who have a family history of glaucoma, diabetes, near-sightedness, and who have a history of injury to the eye. Two other risk factors include the use of steroids (cortisone) or being farsighted.
