Glasses and contacts have their benefits – mainly helping people with refractive errors see clearly. Since the late 90’s, lasers have been used to correct these refractive errors in very safe and effective ways. Procedures such as LASIK and PRK have been providing patients with clear vision for over 15 years now. However, many people continue to put up with the inconveniences of glasses and contacts because they have fears or misconceptions about laser vision correction, like LASIK.
One of the most common fears of laser vision correction is losing vision as a result of the procedure. This fear comes from not understanding how your eye works and how specifically laser vision correction works.
How LASIK Works
There are three main parts to the human eye: the cornea, the lens, and the retina. In normal vision, the cornea refracts (bends) light so it can be directed correctly through the lens and onto the retina. The retina works as a transmitter to transfer the message to your brain, where it processes the message to tell you what you are looking at. Refractive errors – nearsightedness, farsightedness, astigmatism – are caused by the cornea being slightly misshapen. LASIK utilizes cool lasers to reshape the curve of the cornea so you can have normal, clear, vision.
Prior to surgery, Dr. David O'Day maps out your specific eye and plans out exactly how to correct your vision. He then programs this plan into the laser, ensuring that the correct amount of your cornea is altered.
There are risks associated with laser vision correction, mainly dry eye. It is essential to ensure that you are an excellent candidate prior to receiving treatment, to give you the best results possible.
Officially there is no reported case of a patient losing their eyesight from LASIK.
