How LASIK Works
LASIK, or Laser In-situ Keratomileusis offers a number of benefits over other forms of laser vision correction because it is performed under a protective layer of corneal tissue. The Excimer laser removes microscopic layers of corneal tissue to change its shape, allowing light rays to focus more directly on the retina. As a result, there is less surface area to heal, less risk of scarring, less risk of corneal haze, less postoperative discomfort, less postoperative need for medications, and vision returns more rapidly, often within a day or so. LASIK can also treat a higher range of vision errors. Although postoperative results vary, most patients are able to pass a drivers' license test without their glasses or contact lenses.
The LASIK Procedure
After your eye has been completely numbed using "eye drop" anesthesia, an eyelid holder will be placed between your eyelids to prevent your eye from blinking. Next, an instrument known as a microkeratome makes a protective flap in the cornea. During this process you may feel a little pressure, but no discomfort. You will be asked to look directly at a target light while the laser reshapes the cornea, usually in less than a minute. The cornea is reshaped under a protective flap.
To treat nearsightedness, the cornea must be made flatter. This is accomplished by removing tissue from around the central area. To treat farsightedness, the central cornea must be made steeper. This is accomplished by directing the laser beam to remove tissue from around the area. To treat astigmatism, the cornea must be made more spherical. By changing the pattern of the beam, tissue is removed in one direction more than the other. Then, the protective flap is folded back in place where it bonds securely without the need for stitches. After LASIK some patients report a slight discomfort that usually goes away within twelve to twenty-four hours.
Are You a Candidate for LASIK?
In general, the ideal candidate for LASIK is over 18 years of age and has healthy corneas. Candidates must not have had significant increase in the prescription in the last 12 months. People with certain medical conditions or women who are pregnant may not be good candidates for LASIK.
Realistic Expectations
The decision to have LASIK is an important one that ultimately, only you can make. It is important that you have realistic expectations and that your decision is based on facts, not hope or misconceptions. The goal of LASIK is to reduce your dependence on corrective lenses. LASIK does not always create 20/20 or even 20/40 vision. It cannot correct a condition known as presbyopia or aging of the eye. This normally occurs around age 40 and may require the use of reading glasses. In fact people over 40 who have their distance vision improved with LASIK may find they need reading glasses after the procedure. Your doctor will provide you with additional information that will allow you to make an informed decision.
In the Blink of an Eye
It takes only seconds to treat a lifetime of nearsightedness, farsightedness and astigmatism. Find out if you are a candidate for this life changing procedure by calling Virginia Eye Consultants to schedule a personal consultation.
1) What is LASIK?
With the LASIK procedure, a thin layer of the cornea is lifted to create a “flap” that stays connected on one side. Next, the Excimer laser sculpts the cornea with a cool, ultraviolet light. Finally, the “flap” is returned to its original position for a quick, natural recovery without stitches.
2) Am I a good candidate for LASIK?
Potential candidates are 18 years of age, have stable vision for 12 months or longer, have healthy eyes, and have realistic expectations.
3) How much does LASIK cost?
The LASIK procedure fee is $1800.00 per eye ($2,300.00 for custom cornea). Virginia Eye Consultants offers a free screening/consultation so that we can find out if you are a candidate and then we can discuss your financing options.
4) Is LASIK covered by insurance?
Generally, most insurance plans do not cover LASIK, but the surgery coordinator at Virginia Eye Consultants can check your individual company.
5) What can I expect during the LASIK consult?
When you arrive for your LASIK consultation, first you will be asked to fill out patient information forms. Next you will meet with one of our technicians for your initial measurements. Then you’ll watch a video about the LASIK procedure and meet with Dr. Scoper. The initial LASIK consultation takes between 2-3 hours because of the extensive testing that will be performed to determine if you’re a good candidate.
6) What tests do I need before the LASIK procedure?
Several tests are done at the LASIK consultation: topography/orbscan dialated eye exam pachymetry measure pupil size refraction/cyclo-refraction
7) Does the LASIK procedure hurt?
No, the actual laser procedure does not hurt. Some patients do experience mild discomfort during the first 12-24 hours but this is typically just a minor annoyance.
8) What are the side effects?
As with any treatment or operation there are risks, even though they are rare. The risks and benefits will be thoroughly explained to you during your screening/consultation.
9) How quickly will my eyes recover?
You should be able to see better in 1-2 hours after the treatment, but you’ll notice the dramatic difference when you wake up the next day. Most people get back to their normal routine quickly-even going back to work the next day. You may need to avoid contact sports and swimming for 2-3 weeks. Your eye doctor will advise you what is suitable for your individual needs.
10) Does LASIK really work?
Yes! Excimer Laser Surgery is being performed around the world. Over 90% of patients who have the procedure obtain normal vision and many others are happy to lessen their dependence on glasses or contact lenses. In a U.S. clinical trial on the B & L Technolas 17 laser , not one patient was dissatisfied with their vision.
