Lasik Eye Surgery
LASIK Eye Surgery There is much to know about LASIK surgery. Let us start by breaking down the acronym "LASIK". Spelled out LASIK stands for "laser-assisted in situ keratomileusis." A laser is used to make an incision across the cornea and a piece of tissue is lifted forming a hinged access panel to the cornea. Once the cornea is exposed the surgeon an ophthalmologist will then reform the cornea so that it better refracts light onto the retina. That is why LASIK is classified as a refractive surgery. Prior to the procedure, the patient will be given a prescription for a course of antibiotics to reduce the risk of infection. Anesthetic eye drops are administered previous to the surgery and an oral sedative may be offered. As part of the pre surgical preparation, the density of the cornea is measured using a device known as a pachymeter.
A corneal topography machine a low powered laser maps the contours of the cornea while detecting defects in the eye. There are three conditions that can be corrected with LASIK Surgery. These are myopia (near or short-sightedness), hyperopia (far-sightedness), and astigmatism which is the aforementioned malformation of the cornea that diverts light away from the retina. It should be noted that Lasik is contraindicated for patients with high-myopia or a cornea that is abnormally thin. The FDA has approved LASIK for individuals 18 or older. You may have cringed a little reading the description above. The fact is that if you are a candidate the befits of LASIK Eye Surgery outweigh the risks. Fewer than five percent of the over half-million Americans who have undergone LASIK Eye Surgery experience complications. On average the complications that are experienced are not serious and do not result in any loss of vision. The bottom line is likely your top concern when pondering whether or not to have LASIK Eye Surgery. The truth is most health insurances consider LASIK to be an elective or cosmetic surgery and will not cover it. The cost of laser eye surgery varies. Currently, the average cost of laser eye surgery is $2,135 per eye. The cost of the procedure is influenced by three factors.
The experience and expertise of the ophthalmologist, a more skilled surgeon will likely charge more. The more up-to-date the equipment the higher the cost. The most modern laser will cost the doctor more. The severity of your condition. Correcting extremely poor eyesight is more involved than correcting eyesight that is less poor. Potentially laying over $4,000.00 out of your own pocket doesn't sound like one of the befits of LASIK Eye Surgery. That cost has to be compared to the cost of continually having to purchase glasses or contacts. For 66% of patients, LASIK minimizes or eliminates the need for corrective lenses. According to one source, the average American will spend about $173.00 on their next purchase of eyewear. Consider also the inconveniences that come with corrective eyewear: loss or misplacement, scratching or breakage. It may take a few weeks for the effects of the procedure to fully manifest themselves, but when they do they will usually be permanent. Prescriptions for corrective lenses will most likely change over time and become more expensive. The probability of needing stitches or any type of dressing is very low. Normally, you can resume living your life without restrictions within 24 hours.
After the surgery, your vision is immediately better. Roughly, 95% of patients have their vision increase to 20/40 or higher. Eighty-five percent of patients experience a return to 20/20 vision. Follow-up visits after LASIK are only necessary if the outcome is not preferable or in the event your vision changes with age. If needs must because your vision has changed with age you can undergo a second procedure years after the first. The patient satisfaction rating for LASIK averages 92-98%. As with any surgery, LASIK entails risks and there are no guarantees. A year after the procedure you may experience the loss of your highest visual acuity. Changes made to the cornea during the procedure cannot be altered. Laser eye surgery is a technically complex procedure. Although the likelihood is minimal circumstances may arise that can permanently and adversely affect vision. Correcting any problems that result from the surgery can only be accomplished with another LASIK surgery.
