Question about Lasik Eye Surgery?
Lu Anne P
I am 50 years old. I have been nearsighted since I was a kid, but the need for reading glasses came much later in life. Right now I have to wear bifocals to function. I would really like to have the Lasik procedure, but my question is if the procedure can be done to correct both near and far sightedness either at the same time or with two separate procedures? Anyone know?
Answer
After around age 40 the natrual lens within the eye becomes less able to change shape and thereby change focus. This is when reading glasses or bifocals become necessary and is called presbyopia. Lasik cannot treat presbyopia, but there are a few workarounds that you may want to consider.
I work for a nonprofit Lasik patient advocacy. We do not provide Lasik, just Lasik information and we certify Lasik doctos who meet or exceed our patient outcome requirements.
Lasik is only able to reduce the need for glasses, and only one set of glasses at that. It is probable that Lasik can make your vision to be as you see through your distance glasses OR as you see through your near glasses (bifocal), BUT not both. You must choose one or the other, thanks to presbyopia.
There are a couple of workarounds. You can have most of your correction but leave yourself a little nearsighted. That means you would be able to see objects near, such as a computer monitor, reading, etc., but you would lose some of the clarity of your distance vision.
Monovision is the process of correcting your dominant eye to distance vision and your nondominant eye to near vision. After a few weeks the brain figures out what is going on and will "look" through the near eye at near objects and will "look" through the distance eye at distant objects.

The problem with monovision is that about one-third of people who try it cannot stand the effects, and even if you adapt well it is very likely you will lose some accuracy of depth perception. Monovision is a workaround, not a total answer, but it can make daily tasks likegetting around the house and being able to see your watch much easier.
The best part of monovision is that you can try it in contact lenses before you have it lasered into your eyes.
A comprehensive examination by a competent doctor will give you more details and help determine if you are a condidate for any form of Lasik or similar laser eye surgery.

How risky is Lasik eye surgery?
Candi
Just looking into Lasik and was wondering how risky the procedure is.
Answer
I don't know where the first response got his/her info from, but I personally know 2 ophthalmologists, 3 optometrists, and 3 opticians who have had it done, so there must be hundreds more around the world also.
The Lasik procedure has been performed in Canada and most of Europe since 1987, and in the USA since 1990 , that is hardly a new procedure, and long term effects are well known after 24 years of doing it.
There is very little risk to the surgery, but the results aren't always as good as hoped for....like with almost any surgery. But if you wear - 8.00 glasses and end up with only a - 0.50 left...it is still a success in most peoples minds.
The most common side effect is dry eyes, but most of those problems clear up in within 1 year at the most. Some see halos around lights at night, which often clears up with time also, but not all. Those people pretty well have to wear glasses with an anti reflection coating at night to eliminate that.
Very often , a slight correction is still needed for the best night vision for driving.
Eventually reading glasses will be needed, but that won't be until you hit 40 or so. Aside from that , thousands have it done every year and there are very few problems considering the number that are done.
The important thing is to do your homework and choose a clinic with a great reputation and lots of experience.
