Australian Researchers Measure Improvements in Vision Post Cataract Surgery

Cataract Surgery

It is a well-known fact that cataract surgery is capable of restoring eyesight. Patients who undergo cataract surgery are shocked by the brightness of colors and better vision in the night. A few of such patients can even diminish their dependence on eyeglasses. However, quantification of better vision is still not clear. Scientists in Australia made use of a driving simulator to measure improvement in vision following cataract surgery. Crashes and near misses reduced by 48 percent post surgery discovers research. The researching team presented their work at the 123rd Annual Meeting of the American Academy of Ophthalmology

With age, many people get cataracts as a normal side effect of aging. It develops slowly over the years with the clear lens inside the eyes becoming unclear. It is generally difficult to differentiate it from various other visions ailments related to age. One might find colors dull or find difficult to see in glaring lights or might become get nearsighted. By the age of 80 years, nearly half of the people would develop cataracts.

Driving Tests Exhibit Substantially Reduced Incidents of Near Misses and Crashes

Hazy lenses of eyes replaced with artificial ones in cataract surgery. This surgery is highly effective, quick, and low risk. However, not every cataract surgery is done the right way. The decision on whether to perform a surgery or not depends on the extent of interference of cataracts on the daily functionalities of life. Ophthalmologists usually start operating with one eye, particularly the one that is more affected than the other is. The success and vision improvement in first eye gives cue for second surgery. Most of the people feel substantial benefit from second surgery on the less affected eye. Vision becomes crisper, driving becomes much easier, and depth of perception becomes better.

Jonathon Ng, MD along with his team at University of Western Australia, used driving simulation on 44 patients to assess vision clarity before the surgery to comprehend how cataract surgery improves the quality of patients’ life. The driving simulation software measured different types of variables, namely uncontrolled intersections, adjusted speed limits, pedestrian crossings, and traffic densities. The patients went through the driving simulation test post first cataract surgery. The driving simulation test repeated after surgery on second eye. The outcome exhibited that post surgery on the first eye, crashes, and missed reduced by 35 percent and after the surgery on second eye, the percentage further reduced to 48 percent.
