LASIK stands for Laser assisted In-situ Keratomileusis. It is a two-step procedure for correcting refractive error, such as nearsightedness, farsightedness or astigmatism. It is currently the most common refractive surgery procedure performed in the U.S.

The Procedure
The entire procedure focuses on the clear surface of the eye called the cornea. This is the same part of the eye where contact lenses are placed for vision correction. When contact lenses sit on the cornea, they change the way that light is bent as it enters the eye. For farsighted people the contact lens bends the light more. For nearsighted people it bends the light less. However, with LASIK, a very sophisticated and precise laser is used to permanently reshape your eye, making it flatter or steeper to correct the error that exists on the surface of the eye. This creates a permanent solution for refractive error that can’t be achieved with contact lenses.

The first step in the two-step process is the creation of a thin flap on the surface of the eye. A special instrument, called a microkeratome, is used to create a thin flap on the surface of your eye. Just like a cheese wire creates a flap when pulled through a block of cheese, the mircokeratome creates a flap in the cornea. This is a very sophisticated process that takes about 15 seconds and is completely painless. This step allows the surgeon access to the middle portion of the cornea where the resurfacing will take place. In some instances, you or your surgeon may elect to use a laser to create the flap. The laser used to create this flap at the Texas Vision & Laser Center is a femtosecond laser called Intralase, and is a completely different laser than the one used to reshape the eye.

Once the flap is created it is pulled back and the second step is performed. The second step involves the reshaping of the cornea by using a very precise excimer laser. The Texas Vision & Laser Center uses the VISX Star S4 excimer laser capable of tracking the very fine movements of the eye at a rate of 10,000 times per second. The usual treatment time will vary depending on the amount of correction needed. But, typically it ranges from 10 to 50 seconds per eye.

Once the laser completes the reshaping of the cornea, the surgeon repositions the flap, and the same two-step procedure is performed on the other eye if both eyes require correction. Once this is completed the flap immediately begins to seal back into place. After about 24 hours the flap is completely sealed. However, it can take two to four weeks for the flap to completely heal. During this time patients may experience mild fluctuations in vision, and are counseled not to rub their eyes or to go swimming.

After the Procedure
To help with the healing process, prescription eye drops are used for approximately one week after surgery. For the first week after surgery, patients are asked to wear a shield over the eyes while sleeping. For the first month after surgery, patients are asked to use artificial tears to help minimize any drying of the eye surface.

For the first few hours after LASIK, patients experience a mild irritation that may feel like something in the eye. However, this irritation rapidly dissipates over the following five to six hours. Keeping the eyes closed at all times, and lubricated with artificial tears, will minimize the intensity and duration of these symptoms.

Immediately after surgery, patients will experience hazy and blurred vision that will persist for the rest of the day. This will slowly improve as the day progresses. However, the vision will not be significantly better until the following day. The next day, most patients have good enough vision to drive themselves to their follow-up appointment without the use of glasses.

LASIK Options
There are many different variables to the LASIK procedure depending on the surgeon and facility you choose. These variables may include the use of different microkeratomes to create the flap or a femtosecond laser like Intralase to make the flap. A second variable that may exist is the brand of excimer laser that is used. There are several different excimer lasers that exist- all are not equal, with some having broader treatment ranges and more sophisticated features.

A third variable to LASIK is usually given as an option to patients. It is an option to select between “conventional” or “wavefront” LASIK. These two options refer to the software used by the laser to reshape your eye. When your eye is measured in the pre-operative exam, the amount of error is recorded by the doctor and used by the laser to calculate the treatment needed to correct the error. Those calculations are performed by either a conventional software program or a wavefront software program to produce a treatment plan. Conventional software programs use simpler calculations, require less information and are usually sufficient for people with small amounts of refractive error. Wavefront software programs use complex calculations that take into account much more information about the eye. People with complex refractive error, or who have larger amounts of refractive error, usually do better with wavefront technology. The name of the wavefront software for the VISX laser is CustomVue, and the wavefront procedure with this laser is referred to as Custom LASIK. You and your doctor will have to determine which procedure, conventional or wavefront, is best for you.

Overview:  Our patient’s health and care remains our top priority.

In response to guidance from local, state and federal authorities, Texas Vision & Laser Center is adapting to the rapidly changing environment in numerous ways including modifying clinic hours, procedures and protocols.

In light of this unprecedented situation, where things are changing rapidly and often, we request that you help us keep patients and our staff safe by: 

Communicating directly with our staff (3 days before your appointment - by phone, text or chat), to ensure that we are open and so we can advise you of new check in protocols.  (Please ignore ‘automatic’ appointment reminders from our office until further notice.)

Calling or texting us if you need to reschedule, so we can have our office staffed appropriately.

Calling and rescheduling if: 

  • You have tested positive or presumptive positive for COVID-19.
  • Anyone you have been in contact with has COVID-19 or has tested presumptive positive for it.
  • You know you have been in contact with anyone who was in contact with someone who has or has tested presumptive positive for COVID-19.
  • You have been out of the state of Texas in the last 21 days.
  • You have been out of the country in the last 21 days.
  • If you have a cough, fever or any other COVID-19 symptom.

The health and safety of our patients and staff is our top priority and you can expect greatly enhanced protocols for reducing the spread of infection including increased disinfection of our office, equipment, furniture etc., limiting the number of people in our office, screening all who enter for fever and other COVID-like symptoms, ensuring social distance and more.

Texas Vision & Laser Center will continue to monitor the situation and do everything in our power to provide service to all our patients who need it, while following the recommendations and guidelines of authorities and medical best practices.
