Medical Forum / General / Vision / January 2005Does myopia get better with age?
Some people claim their myopia gets better as they age. Is this true? If so, will Lasik to plano result in hyperopia later on? > Some people claim their myopia gets better as they age. Is this true? Some people become less myopic in their forties due to relaxation of the ciliary muscle, usually by less than 1D. Some get more myopic due to increase in density of the lens. Some don't change. >If so, will Lasik to plano result in hyperopia later on? If they were in the group becoming less myopic, yes. Dr Judy >> Some people claim their myopia gets better as they age.

Seems my aunt had her vision improve in one eye by 2D(-5D to -3D). perhaps she had been previously overminused in that eye when she was younger. Happens a lot. >>> Some people claim their myopia gets better as they age. Is this true? >> [quoted text clipped - 9 lines] > > Thanks.

About half of them, but it's usually only a half-diopter or so. Non-myopes experience the same shift, and in hyperopes sometimes it's a dramatic change. > If so, will Lasik to plano result in hyperopia later on? You betcha. Still, plano is what most want, and expect. This is one of the good reasons to target -0.50 or -0.75 as an endpoint. The other is that -0.50 makes presbyopia much less annoying. -MT >Some people claim their myopia gets better as they age. Is this true? If so, >will Lasik to plano result in hyperopia later on? It's called "hyperopic shift". http://www.optometrists.asn.au/gui/files/ceo826236.pdf Hope this helps Robert Martellaro ~~~~~~~~~~~~~~~~~~ Optician/Owner Roberts Optical robopt@execpc.com ~~~~~~~~~~~~~~~~~~ "Science is a way of trying not to fool yourself." - Richard Feynman > It's called "hyperopic shift". > > http://www.optometrists.asn.au/gui/files/ceo826236.pdf > > Hope this helps Thanks, it's very useful. Guess that rules out lasik for me since it seems myopia in my family regresses by large amounts in the presbyopic years and I'm already in my mid-30s. My current -2.25 & -3.00 would probably end up as -0.25 & -1.00. I have witnessed 40 years old ex -3 D myopic who have cured their distant vision and can read microscopic print (1/3 mm) at 20 cm distance. g.ga...@agora.it wrote: > I have witnessed 40 years old ex -3 D myopic who have cured their > distant vision and can read microscopic print (1/3 mm) at 20 cm > distance. Well if you were a -3D myope you could see at 20 cm pretty well. Wow you're a genius. what if someone has had cataract surgery ? Does the eye still continue to change as one gets older? Or does the set focal point remain at the orignal length? There is much less change after cataract surgery. However, it does happen. ------ > what if someone has had cataract surgery ?

Since the lens is the source of much of the variation in refractive error over time in adults, those who have had cataract surgery (ie no longer have their lens) tend to have very little future change. It does happen, but is unusual.
