Barely Visible Device Can Save Your Eyesight

An estimated 3 million people have glaucoma, and many do not realize it, which can be dangerous because it can lead to blindness if untreated, but a device barely visible to the naked eye is helping many patients in the D.C. area keep their vision intact.

The iStent is the smallest implantable medical device in the world. “It's smaller than the lettering on a penny,” Dr. Jonathan Solomon said. Though hard to see, the tiny device can help save eyesight.
 


Management of Residual Astigmatism

Astigmatism is a common occurrence in healthy eyes. It is essentially a natural blurriness that results from an imperfect optical shape of the cornea, or the “window” of the eye. The shape of the cornea is typically round, but with astigmatism it develops in more of an oblong shape instead of spherical, which leads it to mis-focus otherwise healthy vision. In most cases, people with astigmatism are born with this condition, thus the likelihood of developing astigmatism is inherited. However, sometimes astigmatism can develop after an eye injury, eye disease, or ophthalmic procedures that require an intraocular lens implantation (IOL), such as with cataract surgery. The occurrence of astigmatism developing is referred to as residual astigmatism. Head over to our blog to learn more!

Prediction and calculation of residual astigmatism is possible if a patient is evaluated for various options and consequences of different lens techniques before fitting. In doing so, the outstanding possibility of poor vision can be reduced and extended post-operative complications can be avoided.
