Cataract Surgery

Cataract is a clouding of the lens inside the eye which leads to a decrease in vision. Cataracts occur when there is a buildup of protein in the lens that makes it cloudy. This prevents light from passing clearly through the lens, causing some loss of vision. Although many cataracts are not significant enough to require treatment, surgical removal of cataracts is usually safe and effective, resulting in improvement of vision.

Signs and Symptoms
•    Clouded, blurred or dim vision
•    Increasing difficulty with vision at night
•    Sensitivity to light and glare
•    Seeing "halos" around lights
•    Frequent changes in eyeglass or contact lens prescription
•    Fading or yellowing of colors
•    Double vision in a single eye
Phaco emulsification for cataract surgery is a procedure in which an ultrasonic device is used to break up and then remove a cloudy lens, and replaced with an intraocular lens implant, or IOL. 

How is it done?
•    Cataract surgery is usually performed as an outpatient procedure under local anesthesia.
•    Two small incisions are made in the eye where the clear front covering (cornea) meets the white of the eye (sclera).
•    A circular opening is created on the lens surface (capsule).
•    A small surgical instrument (phaco probe) is inserted into the eye.
•    Sound waves (ultrasound) are used to break the cataract into small pieces. The cataract and lens pieces are removed from the eye using suction.
•    An intraocular lens implant (IOL) then placed inside the lens capsule.
•    Usually, the incisions seal themselves without stitches.
Why is it done?
The only true treatment for cataract is surgical removal of the cloudy lens. Surgery is suggested if the patient loses the ability to perform necessary activities of everyday life, such as driving, reading, or looking at computer or video screens, even with glasses, and there is the expectation that vision will improve as a result of the surgery. People who have surgery for cataracts usually have improved vision, increased mobility and independence and relief from the fear of going blind.
Phacoemulsification and intraocular lens implant surgery is ideal for individuals with no other eye disease.  Patients with diabetes are known to be at a high risk for worsening eye problems after this procedure. The surgeon will make the final determination of each patient’s eligibility for the procedure after an examination and consultation with the patient.
For less severe cataracts, vision may improve by changing eyeglasses, using a magnifying glass or increasing lighting. Beyond these measures surgery is the only effective treatment.  The surgeon may discuss alternative surgical approaches to Phacoemulsification including direct surgical removal of the entire lens and/or lens capsule.
