Laser-assisted in situ keratomileusis (LASIK) eye surgery is the best known and most commonly performed laser refractive surgery to correct vision problems.
The cornea is a part of the eye that helps focus light to create an image on the retina. It works in much the same way that the lens of a camera focuses light to create an image on film. The bending and focusing of light is also known as refraction. The imperfections in the focusing power of the eye due to the shape of the cornea and the eye results in blurred or distorted image formation on the retina. These are called refractive errors.
There are three primary types of refractive errors: myopia, hyperopia and astigmatism.
Combinations of myopia and astigmatism or hyperopia and astigmatism are common.
How refractive errors are corrected?
Glasses or contact lenses are designed to compensate for the eye's imperfections. Surgical procedures aimed at improving the focusing power of the eye are called refractive surgery.
Refractive eye surgery is non-essential eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses. This can include various methods of surgical remodeling of the cornea, lens implantation or lens replacement.
Refractive surgery might be a good option for you if you:
What are the types of refractive surgeries?
Because of refractive instability, eye surgeons recommend performing LASIK only to patients after turning 18 when the eyes are at ocular maturity (or have completed growing). To qualify for LASIK, it should be between 0 and -6.00 and your eye number should be stable for at least 6 months. Your cornea and retina should be healthy. Your cornea should be of adequate thickness, and you should not have keratoconus or other diseases of the cornea.
There is no upper limit preventing seniors from having LASIK eye surgery, but many factors must be taken into consideration before a senior adult is approved as a candidate. Cataracts, an eye condition most often affecting seniors, is one of the reasons for someone in this age group to be considered ineligible. If you have reached the age of 60 with clear eyesight, you might still be considered a good candidate. If cataracts have developed, it becomes the priority for surgical treatment but does not exclude a patient from future LASIK or other refractive lens surgeries.
The FDA has approved LASIK as a safe and effective procedure. It is important, however, to remember that LASIK is not the right choice for everybody. Some people are not appropriate candidates, and if treated could have less than optimal results.
No. The actual treatment itself is painless. You will be given plenty of anaesthetic drops to completely numb the eye. You may feel a light pressure sensation around your eye, and after the procedure is finished you will feel a gritty sensation in your eye for a few hours but most people experience very little pain. We’ll give you a prescription for a pain reliever should you need it.
The actual procedure usually takes less than 10 minutes per eye, the laser itself only takes 20-50 seconds to correct your vision. However, you should plan on being in the clinic for approximately an hour-and-a-half on your day of surgery.
Based on clinical data from the FDA and our personal experience LASIK is very accurate. Careful and a complete preoperative evaluation help our surgeons to achieve excellent results with the vast majority of our patients. Even with our advanced technology and experience, approximately 1 in 1000 patients may need to have a retreatment to achieve their best uncorrected vision. This is because we are treating human tissue and there is always some variability in how each individual’s eye will heal.
Your eye will be held open with a holder (speculum) supporting your lid so that you can’t blink. The holder is placed immediately before the treatment and removed immediately afterward. Your job is simply to focus on a blinking target light. While you are doing this, the laser’s computer will also be using its tracking system to monitor the position of your eye. The eye tracker adjusts the laser treatment to follow the small movements everyone’s eyes make during the procedure.
Visual recovery varies from one day to one week. The majority of patients resume normal activities one to two days following surgery but rarely it may take 1 to 2 months for your vision to fully stabilize. Initially, your vision might not be crisp and may fluctuate slightly. This is perfectly normal and should improve gradually day by day.
On the day of your surgery, it is important to have a driver take you home. You will also need a driver to bring you to your post-operative appointment the day after surgery. In most cases, patients are able to drive by the end of that day.
With an experienced surgeon, the procedure itself is relatively safe. Before considering surgery, we carefully evaluate each patient to understand whether or not you are a good candidate. The majority of patients who are safe candidates for treatment have a trouble-free experience. The doctors will be happy to discuss any concerns that you may have. Our goal is for you to understand as much about this treatment as possible before surgery so that you can be comfortable with your treatment options. Factors to keep in mind before undergoing Lasik are: Under or over correction, corneal flap healing problems, pain or discomfort, dry eye, hazy vision, sensitivity to light, glare at night, loss of best corrected visual acuity, or infection. Statistically, there is a very rare possibility of the loss of vision due to corneal infection or inflammation which we address by maintaining sterile conditions in the laser suite and by instructing you to use medicated drops after the procedure.
