Eye Post #2: LASIK Pros & Cons

DISCLAIMER: The following information is my own opinion. The statistics/information are found on the Internet. By no means am I implying that I am 100% correct in my words. Please speak to an opthamologist for more detailed information on this procedure. 

Procedures to correct vision are becoming more prominent in today's society. There are just some people out there who want to be done with glasses or contact lenses for good... and LASIK is one of the popular procedures out there that can do just that. Some people have asked me about my thoughts regarding LASIK and whether it’s safe or worth it. Here I’ll briefly give some pros and cons about the procedure so that you can make the decision for yourself. :)

LASIK stands for "Laser-Assisted in situ Keratomileusis"... which basically means laser vision correction. It can help correct myopia (near-sightedness), hypermyopia (far-sightedness), and astigmatism.  The procedure is performed by an opthamologist and he uses a laser beam to reshape the cornea (transparent, convex surface at the front of the eye) so that when light passes through, the cornea will be able to bend/refract the light onto the retina. An image is clear and focused only when the light is able to focus on the retina, not in front or behind. It is an invasive procedure as the cornea needs to be cut to produce a flap that can open up to the inner layers where the laser beam will work.

Pros to LASIK:
- Both eyes can be treated with LASIK at the same time.
- Quick recovery: normal vision returns several hours after the procedure and one can get back to normal activities two days after.
- After operation, there will be no need to wear glasses or contact lenses
- Easier involvement with sports, no need to wear any prescription sunglasses or goggles or eyewear while playing.
- Health insurance (depending on what plan) can cover a part of the LASIK procedure cost.

Cons to LASIK:
- Procedure is not open to everyone with myopia/hypermyopia/astigmatism, one has to undergo screening to see if they meet the requirements to be a LASIK patient.
- An expensive procedure, each eye costs around $2200 to correct with LASIK.
- If any under or over correction is mistakenly done during initial operation, another operation will have to follow in order to correct it (can't be fixed with glasses).
- Not risk-free: dry-eye syndrome and subconjunctival hemmorhages are common post-operation symptoms among others that can result.
- Not a permanent outcome, the cornea will still deteriorate and visual acuity will decline with age. 

Hopefully you were able to get a better sense of what LASIK is and learn something new! If you have any questions, comment below and I'll try to answer to the best of my ability.

Until next time, Des

  1. Good article ;)

    I do want to highlight the point about how it's not permanent. Your visual acuity can still change with age, and you will still be prone to the aging of the crystalline lens that will result in presbyopia (reading glasses needed), which can start from your 40s. Also, your VA changes, and as you age, your eyes tend to become more hyperopic, or far sighted by the time you are in your 50s-60s.

    This is usually the biggest outcome that patients do not understand about corrective procedures.
