LASIK Surgery in Houston, TX
Eye Excellence, serving the residents of Houston, Missouri City and the surrounding area of Texas and led by board-certified ophthalmologist Mary T. Green, M.D., Ph.D., F.A.C.S., performs LASIK surgery. LASIK can correct most prescriptions whether you are nearsighted or farsighted or have astigmatism in as little as 10 minutes per eye.
What Is LASIK?
LASIK is the acronym for a procedure called Laser In Situ Keratomileusis, which refers to the use of a laser underneath a corneal flap (in situ) to reshape the cornea (keratomileusis). This procedure uses a highly-specialized laser (excimer laser) that is designed to treat refractive errors, improve vision and reduce or eliminate the need for glasses or contact lenses.
This procedure improves vision by altering the shape of the cornea, which is the transparent covering on the front of the eye. Although the excimer laser had been in use for many years prior, the development of LASIK surgery is generally credited to Ioannis Pallikaris from Greece around 1991.
How Does LASIK Work?
- A femtosecond laser is used to make a flap in the cornea.
- Once the eye is lined up in the laser path, a tracking system using three cameras is activated and begins tracking the tiniest eye movements up to micro-millimeter.
- The excimer laser beam is activated and used to gently reshape the cornea to the patient’s precise prescription; the laser is accurate within 1/100,000 of an inch.
- Following the reshaping process, the flap is folded back to its original position and seals itself to the rest of the cornea within minutes.
- In most patients, the entire procedure takes about 10 minutes.
- Most patients recover their vision typically within several hours.
What You Will Experience:
- A local anesthetic is used to numb the eye and prevent discomfort.
- Dr. Green will administer one low-dosage Valium to ensure that you’re relaxed and comfortable.
- Most patients experience a slight pressure during the procedure, but report minimal to no discomfort.
- Following the procedure, you will wear protective eyewear and be driven home to rest your eyes and relax for the remainder of the day.
- A day later, you will return for a post-operative examination.
What Is Refractive Error?
The cornea and the lens inside the eye work together to create a unique “focusing system” whose main function involves focusing rays of light onto the surface of the retina. Under ideal optical conditions, the lens and cornea match the length of the eye and images are always in focus. When the optical system is imperfect or mismatched, a refractive error causes images to appear blurred.
What Are the Primary Types of Refractive Error?
Myopia (nearsightedness): Patients who are nearsighted have a discrepancy between the length of the eye and focusing abilities. This condition causes distant objects to appear blurry and closer objects to appear clearer.
Hyperopia (farsightedness): People with hyperopia have the same problem of mismatched eye length and focusing ability as patients who are nearsighted; however, in hyperopia, objects that are close appear blurry while objects at a distance appear clearer.
Astigmatism: In people with astigmatism, either the shape of the cornea or lens may be distorted, creating multiple images on the retina. This condition makes objects appear blurry at any distance.
It is not uncommon for patients to present a combination of all three medical conditions simultaneously.
A Variety of Treatments

Dr. Green and our team of experts will help to identify any particular eye health challenges, vision criteria and general health conditions that will determine the best course of treatment for you.
Preparing for LASIK Surgery
Patients who wear contact lenses must completely discontinue use of contacts for a prescribed period prior to undergoing LASIK surgery. Contact lenses may cause problems with the surgery by distorting the shape of the cornea, causing inaccurate measurements and affecting surgical results.
Is LASIK Right For Me?
Eye Excellence in Houston invites you to take advantage of our free LASIK screening. If glasses or contact lenses make your vision significantly better, you are likely to be an excellent candidate for LASIK surgery. If your problem is caused by something other than the shape of your cornea, such as a cataract or a retinal disorder, LASIK surgery is not appropriate. If you are not a LASIK candidate, don’t be discouraged as there are many LASIK alternatives that Eye Excellence will be happy to review with you. You can also take the preliminary LASIK self-evaluation test.
What Kind Of Results Should I Expect from LASIK?
At Eye Excellence, LASIK resulting in 20/20 and even beyond is always the goal. While LASIK surgery does not promise every patient 20/20 vision, it most often significantly improves some aspects of vision. LASIK surgery is very specific in the way it reshapes the cornea. It can correct nearsightedness, farsightedness or even astigmatism.
FDA clinical study data presented at a recent American Society of Cataract & Refractive Surgeons Conference (ASCRS) indicated that 98 percent of the clinical study participants could see 20/20 or better after LASIK.
How Much Does LASIK Cost in Houston?
- Even if your insurance plan doesn’t cover vision correction, you can use cash, a credit card, or approved financing for payment.
- Choose from no-interest plans, extended payment options up to 48 months and no down payment.
