A cataract is a clouding of the lens of the eye that can impair vision. If the impairment affects a patient’s lifestyle, cataract surgery should be considered.
What happens during cataract surgery?
During cataract surgery, the affected lens is removed and replaced by a plastic, clear lens. There are different surgical techniques used to remove the lens. One method is called phacoemulsification. Under local anesthesia, a surgeon uses high-frequency sound waves or ultrasound to break the lens into small pieces. The pieces are removed by suction through a small incision in the eye.
After the clouded lens is removed, it may be replaced with a new, manmade lens called an intraocular lens. This procedure is called "intraocular lens implantation." The power of the manmade lens is selected to fit your eye and to help restore normal vision. Even if the natural lens is replaced with an intraocular lens, it is likely that a new eyeglass prescription will be needed.
Cataract surgery is usually conducted on an outpatient basis, meaning you will not have to stay in the hospital. Cataracts in both eyes are not removed at the same time, but will require separate surgeries.
Is cataract surgery safe?
Cataract surgery is one of the most common operations performed in the U. S. and nearly 98% of all cataract surgeries are completed each year without serious complications. Though this type of surgery is very safe, you should discuss the risks with your ophthalmologist.
What can I expect after surgery?
After surgery, it is normal to feel itching and some mild discomfort. To combat this, your doctor may recommend that you take a pain reliever, like Tylenol. You may also have temporary fluid discharge from your eye and be sensitive to light for a short time following the procedure.
For a few days after surgery, you will need to take medication in the form of eye drops to aid healing, prevent infection, and control the pressure inside your eye. Your surgeon may want you to avoid very strenuous activities for a short period after surgery, but most normal activities need not be restricted.
How soon will my vision improve after surgery?
Vision is usually improved the day after surgery. Maximum improvement is usually achieved when new glasses are prescribed, about a month after surgery.
What are the long-term effects?
In a minority of patients, a clouding occurs on the lens capsule months or years after surgery. In this case, an office procedure using a laser can open a small hole to restore normal vision. Lens implants are permanent and ordinarily do not need to be replaced. They are good for the life of the patient.
Will insurance cover the cost of the procedure?
Cataract surgery is covered by Medicare, insurance and HMOs.
