Refractive Surgery Options

A short video detailing the various refractive surgery options, including LASIK, at South Texas Eye Institute in San Antonio.

What is the definition of LASIK?

LASIK is the acronym for laser in-situ keratomileusis, meaning the surgical reshaping of the cornea to correct refractive errors.

In its simplest form, this laser vision correction surgery gently reshapes or sculpts the inner cornea with a cool ultraviolet excimer laser to correct the common refractive errors of nearsightedness, farsightedness, and astigmatism. Prior to laser refractive surgery, wearing glasses and contact lenses was the only way for these patients to see clearly.

The main job of our eyes is to focus light precisely on our retina, which in turn sends that image to our brain. How well you see depends on the particular shape of your cornea. In order to have clear vision, light must reach the retina at precisely the correct point.

If your cornea is too flat or too long, it will fall in front of or beyond the retina, and vision is not clear. If you have an irregularly shaped or uneven cornea, then everything is blurry as with astigmatism. The LASIK treatment changes the shape of the cornea so the light will focus correctly on the retina giving patients clear focused vision.

How does LASIK work?

Laser eye surgery procedures adjust the shape of a patient’s cornea or lens, the anterior segment of the eye. This changes the focal point of the light that passes through the eye, correctly focusing it onto the surface of the retina (the nerve layer at the back of the eye that transmits visual images to the brain).

In recent years, Laser Assisted in-Situ Keratomileusis (or LASIK), has found an even larger niche in modern refractive surgery.

In lieu of scraping away the epithelium (the outermost layer of the cornea), LASIK involves creating a flap of corneal tissue, which is then folded to the side. An excimer laser is used to reshape the stromal tissue, the layer below the epithelium.

Following treatment, the flap is repositioned and the two cellular surfaces quickly heal. The hinged flap technique has become renowned for the speed and ease of visual recovery, and there is no pain.

During Your LASIK Evaluation

During the evaluation a series of tests will confirm the depth of a patient’s cornea, the pressure inside the eye, and the overall health of each eye. Each eye will be measured and evaluated since no two eyes are alike. Dr. Martėn will use the information gathered during the evaluation and design a surgical plan to optimize the visual results. Accept nothing less than a comprehensive evaluation and beware of quick assessments.

Myrandah, Lasik Coordinator:
I am one of the Refractive Consultants at South Texas Eye Institute. I assist patients with initial Refractive screenings and take patients through consultation process from start to finish. Consultations consist of Diagnostic scans, vision check and discussing surgical options available as well as fee’s and finance options available. I also assist Dr. Marten during the surgical process.

I started my background in ophthalmology in 2011 where I started off as a technician and eventually worked my way up to become a refractive counselor. I am a “Certified Laser Technician”. I have thorough knowledge of LASIK and refractive procedures.

(Relating to a patient’s perspective)
I had lasik performed on my eyes in 2012 and have since been able to achieve 20/15 vision. Prior to having the procedure done I was dependent on both glasses and contacts and also had an astigmatism in both eyes.

My vision was bad enough to where I could not leave home without some type of correction. Glasses were a hassle and contacts become bothersome over time especially dealing with dryness. My night driving was becoming an issue and I suddenly found my vision becoming an issue with everyday activities such as reading, watching movies, tv and also trying to play sports, swimming, and etc.

I started to wonder what life would be like without the hassle of glasses or contacts and how nice it would be to open my eyes one day and wake up and have the ability to see clearly. Once I decided to make that dream a reality, my life changed!

Having Lasik gave me back the quality of life I was missing and I was finally able to say goodbye to glasses and contacts. I had the custom view technology and noticed a significant difference in my overall quality of vision, suddenly colors were more vibrant, I noticed a lot more detail in things and felt like I could see better than I ever did with glasses or contacts. All of my vision problems were suddenly a thing of the past! In my opinion, the custom view technology provides an HD quality treatment and corrects imperfections in the cornea that cannot be corrected with glasses or contacts giving you a more precise outcome.

I am now able enjoy quality vision and enjoy sunglasses on a bright sunny day, and see ranges of distance I never imagined prior to the surgery. Having lasik surgery was a life changing experience for me and probably one of the best decisions I have ever made for my vision.

Being a patient once myself gives me the ability to relate with patients considering having lasik or other refractive surgeries done. I would highly recommend Lasik as a surgical option for those considering having the procedure done if they qualify. It really does make an overall difference in your everyday life and vision. The first step is to scheduling a Lasik consultation and learning about your options.

After Your LASIK Surgery

Proper Postoperative Care

The post-operative care is equally important as the evaluation prior to surgery. Patients will receive prescribed medications, and understand what to expect as the healing process is evaluated on a regular schedule. Proper follow up care is essential for a complication free result.

Our Promise to Our Patients

There are no hidden costs or fees. The evaluation, procedure and post-operative care for a year are all included.

If you currently see an optometrist, we are happy to co-manage care with your doctor.

Our focus is medicine and not the business of laser centers. We provide laser vision correction exams and procedures every day. We do not allow medical decisions to be influenced by cost. LASIK is a surgical procedure and not a “fast and easy fix”. In the unlikely event of a complication, Dr. Martėn and our expert physicians are able to diagnose and treat any possible situation in the correct manner.

LASIK and Presbyopia

Unlike the other refractive errors, presbyopia is not caused by the shape of the eye, but by the aging of the eye. A young, healthy eye is able to use the accommodation, the ability to shift focus from near to far (and all distances in between).

However, as the eye ages, the eye’s crystalline lens begins to lose its flexibility and has trouble focusing on near objects. Typically around the age of 40, a person will notice difficulty with close-up tasks, like reading.

Nearsighted individuals may be able to see better simply by removing their glasses for near tasks. Others will either need to get bifocals (if they already wear glasses for farsightedness or astigmatism) or begin to use reading glasses.

Because the hardening of the eye’s lens is a natural part of the aging process, all adults will eventually be affected by presbyopia.

Looking for an alternative to wearing reading glasses from presbyopia? Consider a monovision procedure. Contact us today to schedule a consultation!

Another option for you if you are a nearsighted presbyopic patient is monovision. Your dominant eye is corrected to be able to focus for distance vision and your other eye is focused for near vision.

Frequently Asked Questions about LASIK in San Antonio

Very few insurance policies cover Laser Vision Correction, however, we would be happy to check with your provider when you come in for a consult.

Because we make every effort to make sure the eye is numb, patients tell us they feel only slight discomfort, not pain during the procedure. After the procedure, most people report a slightly irritated eye for a few hours, similar to an eyelash getting in your eye. But pain is subjective, and when you learn more about the procedure you’ll form your own opinion of what to expect.

LASIK Laser Vision Correction is not necessarily for everyone. The best way to determine your candidacy is with a proper screening and thorough evaluation.

This is a state-of-the-art procedure, which requires minimal down time. The actual procedure lasts under 10 minutes per eye. Most patients can go back to work the very next day. It may be suggested that you rest for one day after surgery with minimal activity.

Don’t worry, a small retaining device (a small speculum) will be used to keep your lids open and prevent blinking. There is no way you will be able to blink and hurt yourself or your visual outcome.

In the majority of all cases, both eyes are done at the same time. But you may elect to have one eye done at a time.
