CATARACT DEVELOPMENT & IMPACT ON VISION

VISUAL ACTIVITY

Following cataract surgery to remove the diseased or clouded natural lens, an artificial implant or intraocular lens is placed into the eye.

Accordingly, most patients notice sight improvement which can be measured by the number of lines read on the eye chart. The overall chance of improvement of sight is approximately ninety-five percent.

This does not mean that there is a ninety-five percent improvement of sight, it simply means that ninety-five percent of patients have a chance of seeing better than what they were seeing prior to surgical intervention. These numbers of course depend on the extent of other underlying eye conditions including retinal and glaucoma diseases.

CONTRAST SENTIVITY

This decrease in contrast caused by cataracts affects night vision and night driving ability. Furthermore, there will be a marked decrease in colour vision perception; however, many people do not realize since it can be a gradual decline over years. Many do not realize that the colour vision had changed until after the removal of the cataract.

While the majority of patients who undergo cataract surgery have had a loss of visual acuity or a loss of reading ability on the eye chart, a large number of patients may undergo cataract surgery to help improve their contrast sensitivity.

This is most commonly done for those patients who have diseased maculae, such as those with age related macular degeneration. For patients with age related macular degeneration, removal of the diseased or clouded lens and the implantation of a contrast enhancing intraocular lenses can help them function better.

Accordingly, contrast sensitivity, or the ability for patients to discern the difference between two areas of differing contrast, can be quite helpful in patients who have reduced visual acuity and who are considered to have low vision.

GLARE

One of the more commonly performed surgical interventions for cataract surgery is for glare associated with the cataract. Glare will manifest as haloes around lights or sparking of the lights. Many people will describe lights as being too bright. Some people will see ghosting or multiple images in the cataractous eye. Glare is commonly seen in those patients who have posterior sub capsular cataracts or cortical cataracts.
