Advances in Cataract Surgery
The lens inside the eye allows us to see our world clearly. When the lens becomes cloudy, our world is no longer clear. A cloudy lens is called a cataract. When the cataract begins to effect our daily activities like reading or driving, it is time to have it removed. It can be removed in a procedure performed in the operating room. This procedure, called cataract surgery, is usually performed in around twenty minutes. Light sedation is used to keep the patient comfortable and relaxed. The patient usually goes home the day of surgery.
During cataract surgery, the cloudy lens is replaced with a clear, artificial lens. This allows most patients to see distant objects clearly. If a patient has astigmatism, they will still need glasses to see clearly in the distance. The toric lens is a special lens that allows patients to see clearly if they have astigmatism. Your surgeon will perform a test that measures the steepness of the cornea. This test, called a topographic corneal map, will determine if a patient has astigmatism that can be corrected with a toric lens.
Patients with minimal astigmatism have the option of choosing a lens that will allow them to see clearly in the distance and at near. Not every patient is a candidate for this lens. Ask your ophthalmologist if this type of lens is right for you.
New lenses allow patients to see clearly both in the distance and up close.
