Cataract surgery is one of the safest, most common, and most successful modern surgical procedures. Over 4 million will be performed this year alone. But that is not the same as saying it is perfectly routine and risk-free! Any surgical procedure, no matter how expertly...Continue Reading
Definitely a treatment, not a "cure." Laser Vision Surgery (LASIK, PRK, SMILE) all work on the cornea at the front of the eye to treat myopia (nearsightedness)and astigmatism. Myopia is overwhelmingly caused by an eyeball that has grown "too big." The cornea plus the...Continue Reading
Is Lasik appropriate for someone in his 60's who is nearsighted, farsighted and has an astigmatism? What might he expect the outcome to be?
Assuming the patient is otherwise healthy and has no significant ocular pathology, it might be appropriate but this would depend on what the patient is expecting. If (s)he wants good distance and good near/reading vision, the only way this could possibly be achieved...Continue Reading
Long term exposure to UV light is a significant one. Long-term use of steroids such as prednisone in the treatment of systemic diseases (e.g. arthritis) can cause a rather quick onset of a specialized type of cataract (regardless of age). Certain metabolic diseases can...Continue Reading
20/20 refers to "normal" visual acuity at distance. There are people, usually younger ones, who can see more sharply than that at distance. In general, the higher the second number (the denominator), the worse the distance vision. But bear in mind if you hear somebody...Continue Reading
The retina is a thin layer of neurologically light-sensitive tissue that is spread over the back 2/3 of the inside of globe (eyeball). It corresponds to film in a camera. The retina sits snugly against the next layer of tissue but is not tightly fixed to it. If the retina...Continue Reading
Supermarket reading glasses do help me see. My Optometrist warned me not to use them. Why is my vision now getting worse?
There is really no medical reason not to use "drugstore" reading glasses when you need help seeing things up close. They will not damage our sight in any way nor will they make you dependent upon glasses by making your vision worse. It is true that better quality optics...Continue Reading
Diplopia is the medical term for "double vision." Most diplopia is caused by a failure of the muscles controlling the eyes to work in harmony, thus causing the eyes to look in somewhat different directions. It can be intermittent or constant, or can be seen only in...Continue Reading
