Over fifty percent of people over the age of 60, and quite a few younger than that, suffer from cataracts. Currently there is no medical treatment to reverse or prevent the development of cataracts. Once they form, the only way to see clearly again is to have them removed from within the eye.
In your parents’ or grandparents’ day, cataract surgery was considered risky, required a lengthy hospital stay and was usually postponed for as long as possible. Today, cataract surgery is performed on an outpatient basis and takes only fifteen to twenty minutes. It is now one of the most common and successful medical procedures performed. In fact, following cataract surgery, many patients experience vision that is actually better than what they had before they developed cataracts.
What are Cataracts?
Cataract Surgery Basics
What to Expect of Surgery Day:
You will arrive at the surgery center about an hour prior to your procedure. Once you have been checked in you may be offered a sedative to help you relax. You will then be prepared for surgery. The area around your eyes will be cleaned and a sterile drape may be applied around your eye.
Eye drops or a local anesthetic will be used to numb your eyes. When your eye is completely numb, an eyelid holder will be placed between your eyelids to keep you from blinking during the procedure.
A very small incision will be made and a tiny ultrasonic probe will be used to break up the cataract into microscopic particles using high-energy sound waves. This is called phacoemulsification.
The cataract particles will be gently suctioned away. Then, a folded intra-ocular lens (IOL) will be inserted through the micro-incision, then unfolded and locked into permanent position. The small incision is “self-sealing” and usually requires no stitches. It remains tightly closed by the natural outward pressure within the eye. This type of incision heals fast and provides a much more comfortable recuperation.
The decision to have cataract surgery is an important one that only you can make. The goal of any vision restoration procedure is to improve your vision. However, we cannot guarantee you will have the results you desire.
Once removed, cataracts will not grow back. But some patients may experience clouding of a thin tissue, called the capsular bag, that holds the intra-ocular lens. In most cases, a laser is used to painlessly open the clouded capsule and restore clear vision with a procedure called a capsulotomy.
Serious complications with cataract surgery are extremely rare. It is a safe, effective and permanent procedure, but like any surgical procedure, it does have some risks. Going to an eye specialist experienced with the procedure can significantly minimize the risks involved with cataract surgery.
After a thorough eye exam, you and your doctor will determine if cataract surgery is an option for you. You will be given additional information about the procedure that will allow you to make an informed decision about whether to proceed. Be sure you have all your questions answered to your satisfaction.
