No. The light used in routine eye exams is not intense enough, nor is it a wavelength to cause damage to the various eye structures. _Written by J. Trevor Woodhams, M.D. - Chief of Surgery, Woodhams Eye Clinic ...
Not really. If you are myopic (nearsighted) and wear contact lenses, there is virtually no difference in the blurred near vision from presbyopia compared to somebody without myopia. If you are myopic, however, taking off your glasses can provide better near vision than when the glasses were being worn....
Yes. LASIK surgery can correct nearsightedness, farsightedness, and astigmatism. Dr. Gina Shetty is an experienced eye surgeon who has been changing client's lives with vision correction surgery. LASIK for Nearsightedness Nearsightedness (myopia) causes patients to have difficulty seeing things that are far away. Because their eye is longer than a normal...
Many years ago it was said: You have to wait until cataracts are "ripe" to do surgery. What that meant was that the discolored natural lens (which is the "cataract") needed to reach such a state of complete density that it could be manually pushed out of...
Not sure if your question is asking about SMILE in particular or just about laser vision correction in general. Fortunately, the answer is basically the same for LASIK, PRK, and SMILE. These procedures do not actually "make bad vision good" although that is indirectly what...
There is not really any sort of "guardrail" number of diopters that can be successfully AND safely treated with LASIK. In general, the higher the prescription to correct your myopia (nearsightedness) and astigmatism, the more stress you are creating on your cornea over the rest...
Lots of things related to vision cannot be fixed with LASIK. Disease and degenerations like macular degeneration and cataracts are not at all suited for LASIK treatment. In the world of vision problems that glasses can correct (which is really what refractive surgery like LASIK is meant...
Is the Earth a sphere? More or less. It depends how accurately and detailed you want to measure them. The globe (eyeball) is shaped more like a pear: It has a "bulge" on the front where the cornea, iris, and natural lens are. The curvature of...
The corneal flap that is created in LASIK involves the outermost 3 of the 5 total layers of the cornea. Those are 1)epithelium, 2) Bowman's membrane, and 3) the stroma. The first of these is the protective layer (like epidermis in the skin). Bowman's layer is actually...
First off, you need to know that 20/20 does not mean "perfect vision." It just means normal, typical distance visual acuity (sharpness). [Most young people can actually see better than that at distance, if only with contact lenses or glasses.] By the time we reach middle-age...
