The human crystalline lens, which is clear and transparent, is part of the focusing mechanism of the eye. With age, the lens becomes cloudy and opaque, thereby hampering normal vision. This condition is called ‘Cataract’ or ‘Safed Motia’. Most cataracts are the result of the natural process of aging. Other causes of cataract are metabolic disorders such as diabetes, excessive exposure to sunlight, lifestyle disorders like heavy alcohol consumption and smoking. Injury to the eye can also lead to clouding of the lens of the eye.
About half the population by the age of 60 will get cataract, while around 80 per cent people will have cataract in atleast one eye by the age of 70 years.
Symptoms of Cataract
Hazy, fuzzy and blurred vision
Increased sensitivity to light
Poor night vision
Rapid need to change eye glass prescription in the early stage
As cataract develops, high power glasses would no longer improve the vision
During cataract surgery, the cloudy lens is removed or cleaned out and replaced by a clear artificial lens. After the cataract is removed, the surgeon usually replaces it with a new, manmade lens called an intraocular lens or IOL. This procedure is called “Intraocular lens implantation.”
The IOL is a clear plastic, acrylic, or silicone lens with an optical power chosen by the surgeon to help restore patient’s normal vision. This lens is permanent and needs no special care. Still, even if your natural lens is replaced with an intraocular lens, you probably will need a new eyeglass prescription. However, most people can see fairly well at a distance without glasses after modern cataract surgery with a lens replacement.
The actual surgery usually lasts less than an hour and usually it is not advisable to remove cataracts in both eyes at the same time. If you need both eyes done, you will be scheduled for separate surgeries, usually a few weeks apart. Nearly 98% of all cataract surgeries are completed each year without any serious complications. Though this type of surgery is very safe, you should always discuss the risks of surgery with your eye surgeon.
Vision is usually improved the day after the surgery. Maximum improvement is usually achieved when new glasses are prescribed, about a month after cataract surgery. Be sure to use all medications as prescribed to make sure you get the best possible results.
Clouding of the lining of the lens may occur months or years after cataract surgery. In this case, an outpatient procedure using a laser can be performed to restore normal vision in the eye. Lens implants are permanent and ordinarily do not need to be replaced. They are good for the lifetime of the patient.
