Accidental Discovery in 9th Century Text Book
Recent news about a study from the University of Nottingham caused quite a stir in the medical world. The reason? A medieval recipe designed to cure eye infections was recreated based on instructions from a ninth-century medical book called "Bald's Leechbook." The recipe called for a specific combination of garlic, leaks, wine, and bile from a cow's stomach. All the ingredients were combined and cooked in a copper vessel. Shockingly, the strange concoction proved to be amazingly effective in a laboratory setting! In fact, it proved effective in killing approximately 90% of MRSA (Methicillin-resistant Staphylococcus Aureus). In the medical world today, anything that kills MRSA is a huge deal. This is the superbug that has been plaguing hospitals for years due to its resistance to most antibiotic treatments. What does this recipe discovery mean for us in eyecare? Unfortunately, not much. We're certainly not going to start brewing this concoction at Cool Springs EyeCare. The study falls far short of proving that it would work well on a living person and be safe for use on the eyes. The good news is that it gives researchers new ideas for creating effective antibiotics in the future.

DO I HAVE TO WEAR BIFOCALS? Part III LENS AND CATARACT SURGICAL OPTIONS
When patients develop cataracts, (and we all will develop cataracts over time, as they are part of an aging process in the lens of each eye) the ophthalmic surgeon removes the lens and replaces it with an implant or IOL - intraocular lens. Most of these IOL's are of the "traditional variety," which means the power is adjusted to allow you to see distance with very little need for glasses. However, you generally need a progressive pair of lenses or reading glasses to see for near and computer tasks.
Advances in technology mean we can actually implant a multi-focal lens. The implant gives you the ability to see distance, computer, and near with the goal of not needing glasses much at all. The pros and cons of this have been discussed in other blogs; however, I'll remind you that the advantage is excellent for those patients who truly want to try to achieve independence from glasses. Generally distance vision is excellent (90% achieve excellent distance vision) and the near vision is very good (60-70% of people achieve near independence from reading glasses). We do tend to have patients report more halos around lights, especially at night, and the expense of these lenses is much greater (estimate $1,500 to $3,000 per eye for the benefit of having a multi-focal implant).
If you don't have cataracts, we can actually do cataract surgery on a clear lens. This is an elective procedure. But for many of our patients between 40-60 who are already wearing reading glasses, it provides a surgical alternative to see distance and near and minimize the use of, or need for, reading glasses. It's an option you might want to discuss with your Donelson EyeCare doctor.
