What You Need To Know About LASIK and Refractive Surgeries

Posted // Tuesday, October 22, 2013

Common vision trouble often leads people to consider LASIK, which can free them up from having to wear glasses or contact lenses. While LASIK is the most popular eye procedure, there are other refractive surgeries that can be appropriate as well. Dr. Christian Hester, who specializes in cornea and refractive surgeries at Little Rock Eye Clinic, sat down with Alyse Eady for KTHV’s Medical Monday segment early this week to provide information on both LASIK and other refractive surgeries

Watch the video below to see the interview and read further down for more details.



What is LASIK surgery?

The term LASIK is an acronym for Laser-Assisted In Situ Keratomileusis. It is the most common type of laser eye surgery and is commonly used for the correction of myopia (near-sightedness), hypermetropia (far-sightedness) and astigmatism. So if you suffer from near- or far-sightedness or astigmatism, you are a good candidate for LASIK.

People with mild to moderate myopia, hyperopia and/or astigmatism may benefit from LASIK.  During LASIK surgery, a laser reshapes the cornea to enable proper light focus and clearer vision. There are many different styles of LASIK surgery, such as bladeless and custom LASIK. 

For many, LASIK can correct vision so that they no longer need to wear glasses or contact lenses. LASIK allows surgeons to reshape the cornea to properly refract and focus light onto the retina; often times patients will end up with 20/20 vision.


What are the alternatives to LASIK?

These include photorefractive keratectomy or PRK, in which epithelium is removed from the cornea; refractive lens exchange, in which the eye’s clear natural lens is replaced with an artificial lens; and peripheral corneal relaxing incisions or PCRIs, which are often done with cataract surgery. Other key factors make people candidates for surgery — excessive tears; thickness of the cornea; and irregularity (astigmatism).

Little Rock Eye Clinic offers free refractive surgery screenings. To determine if you need a screening, we have quick and easy LASIK quiz you can take that will help us assess what you need so we can communicate it back to you.
