If you have been considering LASIK eye surgery, our practice will help you determine if you are a good candidate for LASIK before you commit to undergoing any type of vision correction.
LASIK surgery is the most popular form of refractive surgery. It is estimated to account for 95% of the laser vision correction procedures that are performed today. If you live in the Houston area and would like more information on LASIK surgery, or if you would like to schedule a complimentary evaluation, contact us anytime.
What All Laser Vision Correction Candidates Should Know!
Are you in the beginning stages of considering laser vision correction? (also referred to as LASIK eye surgery) Are you seeking an Houston LASIK eye surgery specialist? There is nothing more critical in the LASIK eye surgery process than determining proper candidacy for LASIK eye surgery and selecting a LASIK surgeon that will give you an honest assessment and suggest the correct treatment options. Remember, LASIK is not for everyone but if you do meet the candidacy requirements your LASIK outcome could make a tremendous difference in your overall vision and quality of life. The LASIK candidacy process begins with a thorough eye health evaluation to check the overall health of your eye as well as the corneal thickness. During your initial free LASIK screening, we will thoroughly examine your eyes and perform comprehensive testing to make sure that LASIK eye surgery is the right procedure for you.
A medical and eye history will be taken and several tests will be performed
Basic LASIK Candidacy Requirements
Determining if LASIK is Right For You!
Typically, in a patient who is myopic or nearsighted, the light focuses in front of the retina (back layer of the eye) most typically due to one of two reasons: 1) either the eyeball is too elongated thereby the focused light falls in front of the retina or 2) the focusing power of the cornea (clear part at the front of the eyeball) is too much due to the steep curvature of the cornea. In either case, the laser can shave off some of the tissue from the center of the cornea, thereby changing its curvature and focusing power to allow the light to come into focus precisely on the retina.
Alternatively, In a hyperopic or farsighted patient, the light focuses behind the retina due to 1) either the eyeball being too short, or 2) the curvature of the cornea being too flat, leading to a weakened focusing power of the cornea. In either case, the laser can correct the problem by removing some of the tissue from the surrounding parts of the cornea, and thereby "steepening" its central power and its focusing power, leading to a precise focusing of the light on the retina.
When the patient has astigmatism, the cornea is more of a "football" shaped. In those cases, the laser re-shapes the cornea by removing tissue from some parts of the cornea to make the cornea more spherical in shape.
LASIK is now the most popular procedure to correct nearsightedness, farsightedness, and astigmatism in the world. Its popularity is founded on the high rate of patient satisfaction, excellent visual results, quick recovery, and the existence of very few side effects or complications.
LASIK is performed under a hinged flap of corneal tissue. Once the flap is created and folded back, the excimer laser removes corneal tissue, reshaping the underlying tissue to correct any vision abnormalities. The corneal flap is then relocated over the treated area where it bonds with no need for stitches. LASIK patients experience little, if any discomfort. Functional vision returns very rapidly, with the majority of patients seeing well enough to drive in a day or two, without the need for glasses or contact lenses.
Q. What results can a person hope to achieve?
A. LASIK has proven overwhelmingly successful in reducing dependence on glasses and contact lenses. Clinical studies show that most LASIK patients (with mild to moderate prescriptions) have the potential to achieve 20/20 vision or near 20/20 vision. Generally, this means they no longer need or have reduced their dependence on glasses or contacts to drive, play sports, watch movies and TV, or participate in careers requiring excellent vision.
Q. Who is a good candidate for LASIK? A. LASIK can treat a very broad range of nearsightedness, farsightedness and astigmatism. The best way to determine who i 's a good candidate is with a thorough eye exam. Candidates must be 21 years of age or older, in good general health, and have good eye health with no diseases such as cataracts or glaucoma.
Q. How long will the LASIK procedure take?
A. The LASIK laser vision correction procedure usually takes less than 15 minutes in the operating room. The actual laser time is approximately 1 minute.
Q. Are there any risks associated with LASIK?
A. Some potential complications include conditions such as dryness, night glare, under or over-correction, and loss of best-corrected vision. The risks of surgery should be discussed fully with the doctor prior to the procedure. Additionally, proper post-operative care helps to identify and address any potential healing complications.
Wavefront technology was pioneered for space science and physics to aid in reducing aberrations or imperfections in the optical systems of telescopes. In much the same way, wavefront-sensing devices are being used to produce an accurate picture of the optical imperfections found in the human eye. Everyone’s eyes suffer from distortions, commonly called aberrations. Aberrations are divided into 2 main categories known as HIGH ORDER and LOW ORDER. The low order aberrations are very common and are corrected through conventional LASIK, glasses or contact lenses and come in the form of hyperopia, astigmatism and myopia. Wavefront technology actually approaches the issue of the higher order aberrations. Higher order aberrations are unfamiliar imperfections that cannot be measured with a standard refraction. These imperfections are typically measured by an abertometer and in CUSTOM LASIK this data gets converted in a wavefront map of your eye. The wavefront technology treatment actually converts Wavefront information into a laser pattern that is then used to correct higher order aberrations. Once the wave map is created this information is transferred to an excimer and incorporated into the excimer laser treatment.
During the first step of the LASIK procedure, a corneal flap is made. In the past, the corneal flap was created by a mechanical device which used a blade (microkeratome). Today, we offer our patients ALL LASER LASIK using the IntraLASE® femtosecond laser to create the corneal flap, thereby adding a higher level of safety and precision to the LASIK procedure. Using this Blade-Free LASIK procedure, the IntraLase laser delivers over millions of tiny, micron-sized bubbles that gently separate the layers of corneal tissue. This creates a customized corneal flap of the desired thickness, size, orientation, and location. This unprecedented level of control also allows more patients to qualify for LASIK and virtually eliminates many of the complications associated with the past mechanical approach.
