Laser Eye Surgery Questions?
The Truth
1. Does laser eye surgery last forever?
2. What age is appropriate for this surgery?
3. What are possible side effects?
Thank You!
Answer
1. Yes. Eye surgery changes the shape of your eye, and the healing process is taken into consideration, so it will last forever. However, after age 40, focusing up close becomes difficult, but not because of a glasses perscription. This happens because the cryistalline lens loses it's elasticity, and it's a normal process of aging. Reading glasses (which basically induce shortsightness) work by moving the eye's far focus point nearer, thus not requiring the eye to focus up close. There is a type of laser surgery to fix presbyopia (the loss of the lens elasticity) called monovision, in which one eye is set to 20/20 vision, while the other is set to be a little myopic, normally about 20/40 or 20/60. The brain then ignores the myopic eye's input when looking at the distance, and then ignores the emmetropic (normal) eye's input when viewing items up close. Up to 90% of patients abjust to this method well.
2. The age is normally 21, although basically you are qualified for laser surgery when your perscription hasn't shifted for at least a year. Children's eyes change all the time, and the perscription normally rises during puberty, so fixing it at one point would do no good, seeing as how it will change in six months.
3. There are several possible side effects, such as over or undercorrection (although new technological devices nearly eliminate this sideffect), dry eye (many patinets experience this after laser surgery, and it is usually temporary) and decreased best corrected visual acuity (how well you can see with glasses. This happens because of higher order abberations in the eye, although it is nearly eliminated, again thanks to new technological developments).
Before you decide on having laser surgery, you should consult with at least two corneal specialist, just to make sure your eye is suitable for the surgery, and to choose the best type of refractive surgery for your eye (examples of such laser operations are PRK and LASIK). Most healthy eyes won't experience any side effects after six months post op, so long as they are given the best surgery for them.
Edit: just saw that one of the answerers said that monovision can not treat persbyopia. Look monovision up in google (or consult any optometrist) and you'll see that I'm correct.

Corrective Laser Eye Surgery?

I have been told by my eye doctor that I am a great candidate for laser eye surgery. I currently wear contacts, and my vision has been stable for over four years now. I am considering having it done this year. I want honest answers please. Does this hurt during the surgery? Do I feel anything? Will I be in pain after? I researched specialists in my area, so I am confident in the doctor, but I want to know if I will be in pain during and after surgery. How long does the surgery last too? Sorry for all the questions. I've never had any type of surgery before in my life.
Oops, I meant to say Lasik Eye Surgery. Sorry.

Hi Michelle, Please be careful asking questions about something as important as eye surgery to a yahoo message board. There are different types of laser eye surgery so I will presume you are talking about Lasik. Be sure you are a perfect candidate for lasik and not a better candidate for PRK or other flapless surgeries, or that you are a candidate but have a higher risk of complications. You need to find a reputable surgeon to help you with this decision. Do not base your decision on an advertised price. Ask your family doctor, your optometrist or another trusted healthcare provider for a referral or recommendation. I prefer these sources rather than asking friends, neighbors or message boards.
The answers to your questions about lasik are: No the surgery doesn't "hurt". You do feel some things during surgery and at some point your eye will feel significant pressure. People usually do not say this hurts but it isn't really comfortable. It is common to have burning, stinging watering eyes for several hours after surgery. This can range from almost no pain to severe. Usually by the next morning the comfort is much better or normal. The surgery lasts 15-20 minutes and you will be at the surgery center for 60 to 90 minutes. Again, if you have confidence in your doctor, ask these questions when you go in for your consult. There is no such thing as a silly question. If you are seeing a reputable doc, you will have all of these questions and many more answered without having to ask at your consultation. Remember, this is elective surgery so you have to have all the facts before you decide if it is right for you.
