Ophthalmological Instruments
As many of you know, I had cataract surgery in my left eye yesterday. I had a follow-up appointment this morning and all seems to be going exactly as planned and hoped. Here are three instruments in the ophthalmologist’s office. On the left is a phoroptor, used to determine the eyeglass prescription needed. The instrument is familiar, even if the name isn’t. Then, in the middle, is a keratometer, which is used to determine the shape of the cornea. Finally, on the right is a slit lamp, used to examine eyes. I’ve spent a lot of time behind this last item over the last five years or so.
