Cataract surgery is effective in improving vision and quality of life functions.
Clear vision requires a clear image on the retina, when the lens is not clear the retina can not receive a clear image. With age, changes in the lens may cause clouding of the lens and lead to cataract.
Early stages of Cataract treatment include: new eyeglasses, brighter lighting, anti-glare sunglasses, and later on, surgery is the effective treatment.

The improvement in vision after cataract surgery, in which the lens is replaced by a new artificial lens, is instantaneous, and usually allows the patient to see again as clearly as before. However, there are many patients who have difficulty adapting to the new vision. These difficulties usually disappear after an adjustment period ranging from a few weeks to many months. The difficulty in vision after artificial lens implants results from a significant decrease in the contrast sensitivity after cataract surgery, and from the brain’s need to adapt to the new image coming from the eye. Contrast sensitivity is the ability to identify and distinguish objects that are not clear against a background similar to them. The contrast sensitivity decreases with age and after cataract surgery. Decrease in contrast sensitivity includes symptoms such as difficulty during night vision , difficulty detecting stains on clothes or dishes, difficulty distinguishing facial expressions and a need of more lighting to read.
A visual acuity test gives quantitative information about the vision, while a contrast sensitivity test provides information about the quality of vision.
RevitalVision eye exercises improve contrast sensitivity post cataract surgery by over 150% on average and help to adjust to the new vision, by influencing the vision processing ability in the brain. This goal is reached by Revitalvision eye exercises, practiced at home in front of the computer. These last approximately 30 minutes, and are done under the supervision of an optometrist or ophthalmologist. RevitalVision therapy is clinically and scientifically based.
