It is amazing to us as we look at lenses in our high powered microscopes what we see. A common culprit is what we call the “Formica slide”. This can be a destroyer of lenses on both the front surface, and the edge. Patients need to be aware the dangers of this. It can lead to not only scratches, which thus leads to a degradation of optics and wettability. These scratches can also be the foothold to protein buildup, which dramatically reduces the all important oxygen permeability that makes our product very successful. The most frightening aspect of the countertop menace is the potential damage to the edges. It there is a chip or a crack in the edge, the cornea can easily be scratched, and epithelium can be irritated. If there is ever a crack in the edge, the true danger is the lens breaking in the eye.
If your lens happens to fall down, usually a moist finger is enough to suction the lens off the surface. If it fell edge-down and curve-up so that it won’t easily suction on your finger tip, instead of sliding it across the counter or sink, it would be best to have one of those suction-cup thingies to pick it straight up. I prefer the DMV Ultra.
