Cateract Side Effects

A cataract is the clouding of the eye's natural lenses that lie behind the iris and the pupil. A cataract begins as a small filter and may have little or no effect on vision. As a cataract worsens, vision may become blurred or cloudy. Surgery is usually required to treat cataracts. Any change in vision warrants an eye exam by a qualified professional.

Causes

• The exact cause of cataracts is not known, but it is thought to be a result of the normal aging process for many people. Exposure to ultraviolet light, diabetes, steroid use, diuretics and tranquilizers may also be contributing factors to cataracts.

Vision Changes

• Blurred and cloudy vision are the most common effects of cataracts. Also, colors may appear less vibrant and take on a darkish or dull hue.

Surgery

• Cataract surgery involves replacing the clouded lens with a clear plastic intraocular lens. Most cataract surgery is extremely successful in restoring sight with few side effects.

Detached Retina

• A detached retina is caused by a tear in the retina and can sometimes be caused by cataract surgery, although it is rare. Dark shadows and black floaters may appear. A detached retina is a painful condition and requires immediate care by a physician or eye specialist.

Vision Problems

• According to Dr. Michael Kutryb of the Kutryb Eye Institute, sometimes extreme flashes of light, called strobbing, affects vision after cataract surgery. Numbness and/or a burning sensation may occur in the eyes after a great deal of computer or paper work by those who have had cataract surgery.

Physical Problems

• Dr. Kutryb also warns that headaches and nausea may occur after cataract surgery. This can be the result of reading or focusing on objects that are very close for long periods of time. At times, the dominant or good eye may take over, and the bad eye goes unfocused for several minutes as a result of cataract surgery.
