Laser Vision Correction in Houston, TX
In the United States, LASIK is the most commonly performed laser vision correction procedure. LASIK is not the only option, however, and may not be the right procedure for everyone. At Eye Excellence, located in Houston and serving Missouri City and the surrounding areas of Texas, our board-certified ophthalmologist, Mary T. Green, M.D., Ph.D., F.A.C.S., examines each patient’s circumstance and prescription to determine which laser vision correction option is best suited for their unique visual needs.
Dr. Green is a fellowship-trained corneal and refractive surgeon. She is pleased to offer a variety of the latest refractive surgical procedures, including All Laser LASIK, Photo Refractive Keratectomy (PRK), Refractive Lens Exchange (RLE) and the Implantable Contact Lens (ICL).

What is All-Laser LASIK?
All-Laser LASIK is a procedure that utilizes a femtosecond laser to make a corneal flap and an Excimer laser to reshape the cornea under the flap, making LASIK more precise than ever before. Your cornea is reshaped using a WaveScan measurement specific to your eye (like your unique fingerprint). The All-Laser LASIK procedure takes only minutes to perform and corrects nearsightedness, farsightedness and astigmatism.
A femtosecond laser is used to create a corneal flap costimized to your unique eye shape.
Your Personalized Vision Profile
One of our doctors will perform a complete eye examination to be sure your eyes are healthy. A specialized WaveScan computer is then used to capture the unique blueprint of your eyes; this blueprint is used to guide the Excimer laser during your procedure, giving you a truly customized result. WaveScan technology provides 25 times more precise measurements than standard methods.
Your LASIK Procedure
All-Laser LASIK was designed to offer great vision without the need for contact lenses or glasses by reshaping your cornea so that light focuses properly on the retina. All-Laser LASIK is a two-step process.
After your eye has been completely numbed using anesthetic eye drops, Dr. Green creates a flap of thin corneal tissue using the femtosecond laser. The corneal flap is then folded to the side.
Next, in only a few seconds, Dr. Green reshapes the underlying tissue to correct the refractive errors in your eye based on the WaveScan measurements of your unique optical system. During this step, the 3D ACTIVETRAK eye tracker follows the eye’s tiniest moves. It automatically positions the laser to keep the laser beam focused where it needs to be so you can completely relax during the procedure. Dr. Green then folds the corneal flap back to its original position where it bonds without the need for sutures.
To be a good candidate for All-Laser LASIK, the cornea must be of sufficient thickness to allow for the thin flap to be made, leaving enough underlying tissue to be reshaped to achieve the targeted level of correction.

All-Laser LASIK Results
Many patients notice immediate results after All-Laser LASIK with their vision continuing to improve over several days to several months. It is normal to experience small fluctuations and blurriness in your vision as your eye heals; this can depend on the amount of nearsightedness, farsightedness and/or astigmatism that was corrected. It is also very important to the healing process that you follow all your post-operative instructions.
One year after All Laser LASIK*, patients in a clinical study reported these great results without glasses and contact lenses:
- 100% could pass a driving test
- 98% could see 20/20 or better
- 70% could see 20/15 or better
Both the U.S. Air Force and NASA have accepted All-Laser LASIK as a vision correction standard for their pilots and astronauts.

Frequently Asked Questions
Does LASIK hurt?
Because the cornea is easily numbed with “eye drop” anesthesia, patients report little, if any, discomfort both during and after the procedure.
When will I be able to see after the procedure?
Results vary from patient to patient. Most patients have functional vision in one to three days. Full visual results are usually realized within one to four weeks.
Will I have 20/20 vision?
We hope so, but as with any medical procedure, there is no guarantee that you will have perfect vision or that you will not need distance or reading glasses again. However, almost everyone experiences improved vision and can pass a driver’s test without corrective lenses.
Will I need reading glasses after the treatment?
Generally, patients under 40 years of age read well without glasses following the treatment. Patients over 40 may need magnification for reading fine print. Presbyopia is the term that refers to the natural weakening of the focusing muscles that occurs in our early to mid-40s, causing us to need the magnification that reading glasses provides. The LASIK treatment does not correct or prevent presbyopia. We will be glad to discuss monovision or the possibility of a multifocal lens implant to address this condition.
Will I meet the surgeon?
Unlike many corporate centers, our doctor will see you during your evaluation. The same doctor will perform your surgery and be available for your follow-up care.
What are the risks associated with LASIK?
Like any medical procedure, LASIK has some risks. Your doctor will give you more detailed information regarding risks and complications prior to having LASIK, and all of your questions will be answered.
Is LASIK covered by insurance?
Because LASIK is an elective procedure, most insurance companies do not cover LASIK, However, Eye Excellence does participate in some vision plans, which may offer a reduced fee for LASIK. With approved credit, we also offer no-interest and low-interest payment options that can fit almost any budget.
Refractive Lens Exchange (RLE) and Other Alternatives
Refractive Lens Exchange (RLE)
Refractive Lens Exchange corrects nearsightedness, farsightedness and astigmatism using an intraocular lens implant (IOL). It is an excellent alternative for individuals over the age of 40 and for those who may be showing early signs of developing cataracts. Millions of eyes have received intraocular lens implants when undergoing cataract surgery, using the same highly successful surgical techniques used in the RLE procedure.
The primary difference between cataract surgery and RLE is that cataract surgery is performed to remove a patient’s cloudy lenses, and Refractive Lens Exchange is primarily performed to reduce one’s dependence on glasses or contact lenses. RLE provides patients with the opportunity to see far, near and in between without the need for glasses or contact lenses for most of their activities.
Photo Refractive Keratectomy (PRK)
PRK may be a better choice for some patients with thin corneas or high levels of refractive error. The primary difference between PRK and LASIK is that the surface of the cornea is treated with PRK while the inner tissue of the cornea is treated with LASIK. Both procedures have similar success rates, but LASIK offers patients less postoperative discomfort and a quicker return to functional vision.
Here’s how it works:
During PRK, the outer surface layer of the cornea called the epithelium is gently removed. Using the WaveScan measurements unique to your eye, the Excimer laser reshapes your cornea to correct your nearsightedness, farsightedness and astigmatism. The laser treatment usually takes less than a minute.
After the procedure, a protective contact lens (bandage lens) is placed on the eye to make it more comfortable during the healing process. It usually takes three to five days for the epithelium to fully heal. Most PRK patients notice an improvement in their vision soon after surgery. However, vision is usually somewhat blurred during the epithelial healing process.
Implantable Contact Lens (ICL)
The ICL is a small, injectable lens that is folded and inserted through a tiny, 3-millimeter incision that usually does not require sutures. Once inside the eye, it unfolds and is tucked in behind the iris. It is added to the eye without removing the natural lens. ICL candidates are between the ages of 21 and 34 with moderate to severe nearsightedness, typically outside the range of correction with LASIK. The ICL is unnoticeable to both the patient and any observer and, if necessary, can be removed and/or replaced if your refractive error changes over time.
