Astigmatism
The very front part of the eyeball is the cornea, which I sometimes liken to a “windshield” over the eye. If there is not perfect radial symmetry of the cornea, we say that there is astigmatism. The most common form of astigmatism is one steep axis perpendicular to one flat axis–sometimes we say this is…

There is a procedure that is now not commonly done in ophthalmology called radial keratotomy. When RK is initially done, it gives a pretty nice result for correcting the need for glasses in near-sighted individuals. However, as time goes on, the vision becomes less and less desirable. The biggest problems that I see with RK…

The October 2022 edition of the journal Cornea contains an article by Dr. Prashant Tailor and colleagues. It describes a patient who was injured in the eye by an oleander leaf. Plant-related injuries to the eye often require different treatment than other injuries to the eye. In this case, the patient developed severe swelling of…

I just discovered a video from Dr. Lawrence Tenkman, the EyeNinja. He is an incredible communicator and very funny! The video that I saw was definitely mostly directed toward ophthalmologists, but when people are that good at communication, it seems a shame to keep the audience so limited. It is a good lesson to all…

As ophthalmologists, we pay attention to detail. I suppose it is true that most professionals do, but I was reading some forum posts from ophthalmologists about very subtle aspects of cataract surgery. They were discussing and debating over the course of thirty or forty posts, mainly focusing on different techniques that arguably would make no…
Read MoreChanging Eye Color
In the August 2022 edition of the Journal of Cataract and Refractive Surgery, there is an article edited by Nicole Fram about a patient who had BrightOcular iris implants placed to change her iris color. There is a lot of technical discussion in this article, but the important message from the article is that this…

Recently, an ophthalmologist mentioned that the lens implant he put in during cataract surgery did not look properly centered. For those uninitiated, whenever we take cataracts out of an eye, we usually try to replace it with a lens implant. For some types of lens implants, a lack of perfect centration isn’t the end of…

Something that is on the horizon with cataract surgery is the use of “heads up” displays. Currently, the way I operate employs the use of a microscope that I look into during surgery. It is an actual physical microscope that is above the patient during surgery, and I look directly into the eyepieces. This is…

One of the things about glaucoma eye drops is that they can be pretty nasty to the surface of the eye. Unfortunately, we mostly have to live with this for our glaucoma patients, because the alternative to taking drops is often progressive vision loss to the level of no light perception. A relatively new glaucoma…

As the years go by, there are more and more surgical options to treat glaucoma. In my opinion, this is a great thing, because, historically, glaucoma treatment has involved a lot of eye drops–eye drops that patients must use every day, often multiple times per day. I hope that there are continued improvements in the…
