Medical Forum / General / Vision / March 2006lasik and lenticular myopia
my daughter's doctor advised us that she would not be a candidate for lasik because she has lenticular myopia. i thought lasik would be possible since the problem was with the lens and that it would reshape it. any thoughts on this? > my daughter's doctor advised us that she would not be a candidate for lasik > because she has lenticular myopia. i thought lasik would be possible since > the problem was with the lens and that it would reshape it. any thoughts on > this? Lasik reshapes the cornea, the front window of the eye. The lens is different, an internal part of the eye. Lasik doesn't go anywhere near the lens. Cataract surgery involves extracting the lens from within the eye. Dom > Lasik reshapes the cornea, the front window of the eye. The lens is > different, an internal part of the eye. Lasik doesn't go anywhere near the > lens. Cataract surgery involves extracting the lens from within the eye. And during cataract surgery, an implant is usually inserted to replace the natural lens. The optical power of the implant is chosen to optimize vision and eliminate refractive error, making LASIK unnecessary. The implant only corrects for one distance, so glasses like bifocals are necessary to focus near as well as far. -MT >The implant only corrects for one distance, so glasses like bifocals are >necessary to focus near as well as far. Oh oh. The folks at eyeonics, AMO, and Alcon are not going to like that statement. 8^) There are intraocular lenses (IOL) that are multifocal and there is even a lens that moves inside the eye to create accommodation. Each has distinct advantages and disadvantages. None actually "cure" presbyopia, but each is a workaround that can be acceptable for some. Refractive Lens Exchange (RLE) is probably not appropriate for someone under about age 45 and has the ability to accommodate (change focus to near objects) See http://www.usaeyes.org/faq/subjects/rle.htm for presbyopia, Lasik, IOL, and RLE information.

Your daughter's doctor is offering a more conservative evaluation. Lasik could correct the refractive error caused by the astigmatic lens inside the eye, but this may cause problems later.
