LASIK LASER VISION CORRECTION
LASIK is a type of refractive surgery used to treat patients who are diagnosed with near-sightedness, far-sightedness and astigmatism. You must be realistic in your expectations and be informed that there is no guarantee that you will never need corrective lenses. An analysis of scientific literature by the American Society of Cataract and Refractive Surgery reported that worldwide satisfaction rates among LASIK patients is 95.4%. Certain health concerns such as lupus, rheumatoid arthritis, previous eye infections, and pregnancy are a few of the factors affecting your candidacy for the procedure. The doctor will discuss these and other factors during your free consultation.
There are several factors related to the success of your procedure:
· How much correction is needed?
· What is the health of your eyes?
· Are you 18 years of age or older?
· What is your past medical history?
A clear future can be yours with Laser Vision Correction and the procedure of choice is LASIK. Most experienced refractive surgeons agree that LASIK is the preferred refractive procedure, allowing rapid healing with less incursion versus other procedures. In just a few days your eyes heal and your vision clears. LASIK combines the precision of the Excimer Laser and the skill of an experienced corneal refractive surgeon.
The pre-operative examination is a simple process that gives you the opportunity to ask any questions you may have that aid you in making an informed decision. During the exam your eyes are dilated and a refractive measurement is taken to determine how light is focused on the retina. Computerized mapping of the eye (Corneal Topography) is performed and the thickness of the cornea is measured with an ultrasound. These tests, along with your medical history, help the surgeon to determine your LASIK candidacy.
The procedure is made up of several parts. First you are given eye drops to numb the eye so you will not feel any pain. An oral sedative is usually administered, offering a calming effect. You are awake during the procedure and Dr. Shriver helps ease the procedure by explaining what is happening during every step and what is coming next. While you rest under the laser, an instrument helps hold you eyelid open. A suction ring, which is part of the microkeratome, holds your eye stable while the flap is produced. You may feel pressure but you wont feel any pain.
You are asked to focus on a light creating a target for the laser. You will hear a tapping sound as the laser operates. While small amounts of tissue are being vaporized you will still feel no pain. The first part of the surgery involves accessing the middle section of the cornea called the stroma. This is done by creating a hinged flap with either a bladed tool, called a microkeratome or a femtosecond laser. The next step is to use an excimer laser to reshape the corneal stroma. The last step involves the surgeon repositioning the flap over the treated area and applying antibiotic and anti-inflammatory eye drops.
Blade Free, All Laser Custom LASIK
Wave-front technology, also known as “Custom LASIK”, uses three-dimensional measurements of how images (light), are processed as they travel through various parts of the eye, such as the cornea and the lens. The technology can diagnose lower and higher-order imperfections that exist in the eye by how the eye focuses light. Lower-order aberrations can typically be described as near-sightedness, far-sightedness, and astigmatism. Higher-order aberrations are more complex distortions within the cornea. That information, specific to your eye, is then shared with the laser. The treatment is customized to uniquely reshape your cornea’s surface so that those irregularities may be corrected. This technology has meant a decrease in visual side-effects like glare, haloing, and ghost images which used to be more common occurrences after surgery, before wave-front technology became available. Wave-front technology can be used with LASIK, PRK, or INTRALASE surgeries.
The entire procedure takes about 10 minutes per eye.
Post operatively, the LASIK surgeon will stress the need for sleep or to keep the eyes closed for the next several hours after surgery, to allow the flap to better adhere to the cornea. The patient will be given direction as far as keeping the eyes well-hydrated with moisturizing eye drops and following a protocol of medicated drops for a specific time period.
The purpose of the surgery is to allow the patient to potentially decrease or eliminate the dependency on corrective glasses and contact lenses.
