Getting eye measurements is the first step of the cataract evaluation, and one of the most important. It is performed first because these measurements can be affected by the drops we use to dilate your eyes or check eye pressure, so we want to get pristine measurements before doing anything else. The results of these measurements also help to guide our discussion regarding potential cataract surgery. Once we have the cataract measurements, we proceed to the comprehensive dilated eye exam. This includes checking visual acuity, effects of glare on visual acuity, glasses prescription, eye pressure, and pupils (among other things) prior to dilation. Next the eye(s) are dilated. Since eye dilation can affect one’s ability to drive, we recommend having a driver accompany you to your cataract evaluation.
