Top LASIK Misconceptions: Part One

By on

Today, 98% of patients achieve 20/20 or better vision with advanced forms of LASIK, yet many people have big misconceptions about it. LASIK is the most studied ophthalmic procedure in the world and has been performed on more than 50 million people over the past few decades. Despite the comprehensive studies and global acceptance, LASIK misconceptions persist. To help dispel some these, I am going to address the most common misconceptions I hear on a daily basis.

Top LASIK Misconceptions

  1. “I can’t have LASIK because I have astigmatism.” Astigmatism is a condition in which the eye is more football-shaped than round, and it distorts vision at all distances. LASIK can actually correct astigmatism—even the most severe degrees of it.
  2. My prescription is too severe for LASIK.” LASIK can treat mild, moderate, and even severe degrees of correction. I routinely perform LASIK for people with the most severe 1% of prescriptions in the world, and they do amazingly well.
  3. “I’m farsighted, so LASIK isn’t for me.” LASIK can correct not only nearsightedness and astigmatism, but also farsightedness.
  4. “I’ve heard LASIK will wear off, so what’s the point?” LASIK lasts a lifetime, but it cannot stop the natural aging of the eye. LASIK essentially makes you see like a normally sighted person. And, like all normally sighted people, you will lose your focusing muscle strength as you age (usually in your 40s). You will then need reading glasses or another procedure (KAMRA Inlay) to restore your reading vision.
  5. “I don’t want to have LASIK because I am worried about night glare.” LASIK is no longer associated with a high risk of night glare affecting your ability to drive. LASIK technologies evolved to reduce this risk from 20% in the 1990s to less than 1% today. In fact, studies show that it may even result in less glare than you have today with glasses.

Next Steps

Hopefully I have helped clear up a few of the misconceptions around LASIK. If you still have questions, the most important step you can take is to get all the facts from your eye doctor. He or she can answer all of your questions and provide a referral to a reputable clinic and experienced surgeon.

    My prescription is Sph= (R)+2.25 & (L)+2.25 / Cyl= (R)-0.75 & (L)-1.00 / AX= (R)44 & (L)94 / Add= (R)+2.50 & (L)+2.50. I am also in the beginning stages of cataracts. I am 67 yes old. I was informed that I cannot have the surgery because of these major corrections. Is this true? If not what corrections can be made? Thank you for taking the time to respond.

  • Paul in Seattle says:

    Unfortunately, I have been told many times that due to dry eyes I am not a good candidate for Lasik correction as it will cause stary night vision. Has this also been improved upon?

  • P. N. Gwynne says:

    My Lasik results were perfect when I underwent the pricedure in 2002 at age 44, after years of profound nearsightedness. I’d been so nearsighted I couldn’t read a book without my coke bottle glasses because I couldn’t focus on text more than an couple inches away from either eye. By 2009 things stsrted to get blurry again and I had to return to wearing glasses. While the script 8s much less severe now than it was in 2000 I now, once again, feel dependent on my glasses for anything like watching TV, driving or generally being out of the house. I can do most those things without glasses, and even wrt driving the advent of GPS has practically eliminated the hazards that go with squinting to read signs and street numbers in unfamiliar locales. But I feel that I’m missing out b3cause everything’s just a little blurry. Reading hardcopy text is about all I can comfortably do now without glasses. I usually need my glasses even to comfortably use my computer, although that varies with how I’m sitting.

    Through my entire experience with LASIK, except for a couple of days after the surgery, I’ve never needed readers.

    I have VSP insurance. I thought they didn’t cover lasik due to it being cosmetic. Is this true or can I look into it? I have always wanted to do it.

    Does forming large scars make a difference on wether or not you can have this done?

    Is it better to wait until your near sighted vision stops changing? I am asking with a view to my son and daughter who are 24 and 20.
