A cataract is the clouding of the natural lens in the eye.
Studies have shown that Cataracts are most prevalent in people over 50 years of age, but some people may have congenital cataracts. Approximately 50% of people over the age of 60 will be affected. Currently it is not possible to prevent or reverse the development of cataracts. Surgery is the only permanent treatment option for cataracts.
Once your cataract is removed, it will be replaced with an artificial lens. Great care is taken in measuring the precise lens needed for your eye. Dr Steyn uses various ultramodern devices to determine the power of your lens. If you had previous surgery to your eyes, it may influence the calculations – please inform our staff at the time off consult.
A few decades ago, cataract surgery was viewed as a risky procedure, requiring a lengthy hospital stay. Currently, cataract surgery is much more refined, and is performed on an outpatient basis. This surgery is one of the most common and successful medical procedures performed.
Post surgery, many patients actually experience an improvement to their vision to what they had before they developed cataracts.
What to expect:
After arriving at the Hospital you will be checked in and a sedative may be offered to help you relax. You will then be prepared for surgery. The area around your eye will be cleaned.
Local anesthetic will be used to numb your eye. This procedure can also be performed under general anesthetic. When your eye is completely numb, an eyelid holder will be placed between your eyelids to keep you from blinking during the procedure.
A micro-incision will be made where a tiny ultrasonic probe will be used to break up the cataract into microscopic particles using high-energy sound waves. This process is called phacoemulsification.
The microscopic particles will be gently suctioned away. Thereafter, a folded intraocular lens (IOL) will be inserted through the micro-incision, unfolded and locked into permanent position. The small incision is self sealing and usually requires no stitches. It remains tightly closed through the natural outward pressure within the eye. This incision-type heals fast and provides a much more comfortable recuperation.
Cataract Surgery
Post – Operation:
After your cataract has been removed, it can not grow back, although some patients may experience clouding of a thin tissue (capsular bag), that holds the intra-ocular lens. A laser is used to painlessly open the clouded capsule and restore clear vision with a procedure called a Posterior Capsulotomy.
