Cataract surgery is the surgery used to remove the natural lens of the eye when it has become opaque. When a person's natural eye lens becomes opaque, this is called a cataract . When someone develops a cataract it makes it very difficult to see clearly and glasses or contacts can do nothing to help clear up the problem. For this reason people who have developed a cataract need to have surgery in order to repair their vision.
How Does a Cataract Develop?
The first question that someone with a cataract usually ask is, "How did this cataract develop in my eye?" This is a very important question to know the answer to. A cataract develops when metabolic changes occur in the fibers of the lens. Over time these metabolic changes cause a loss of transparency in the eye's lens. A person's next question may be, "What could I have done to have prevented this?" However there really is no way to avoid this metabolic changes, making it impossible to prevent yourself from ever developing a cataract. This does not mean that everyone will develop a cataract in their life; it just means that there aren't any health practices you can follow in order to ensure that you will never get one.You can, however, look out for signs for a cataract.These signs include experiencing a strong glare from lights and reduced sharpness to low light levels. If you notice these symptoms then you should go to your optometrist to check your eyes for a cataract.
After a doctor has examined your eye and confirmed that there is a cataract, the doctor will determine if you are a candidate for surgery. During the actual cataract surgery the patient is put under anesthesia. The pupil is dilated and the doctor enters the eye through a minimal incision. The doctor then injects stabilizing substances to maintain the pressure in the eye. They destroy the cataract and insert an intra-ocular lens, which is a synthetic lens that restore the lens's transparency. The wound is then sealed and the eye is hydrated if it needs it, depending on how long the eye went without blinking hydration.
