For their size, your eyes are incredibly complex structures that rely on a precise balance and shape in order to help you see clearly. When light first enters your eye, it passes through your cornea, which refracts the light through to your lens, which then focuses the light onto your retina. From there, your retina sends the information to your optic nerve, which translates it into electrical impulses for your brain to create an image.
Any minor problem in this delicate chain can throw off the information, causing the resulting image to be distorted.
Most astigmatism occurs when your first point of entry — your cornea — is misshapen. Your eye functions best when it’s round, but if your cornea is irregularly shaped, it prevents the light from focusing on your retina properly.
There are many solutions for astigmatism and it largely depends upon the degree of the problem. To start, Dr. Krad performs an extensive eye exam that measures how your eyes refract light. Dr. Krad can figure out the extent of your astigmatism using a test called a retinoscopy, where he shines a light into your eyes and tries different lenses in front of you to gauge the degree of the problem.
Armed with this information, Dr. Krad reviews your options. In mild cases, corrective glasses or contact lenses may do the trick. If you already wear soft contact lenses, you may have to switch over to gas permeable lenses, which are stiff in shape, making up for the irregular shape of your cornea.
The answer to this depends upon the degree of your astigmatism, but in most cases, refractive surgery can help you regain clear vision. To do this, Dr. Krad turns to LASIK, or laser-assisted in situ keratomileusis. During the procedure, Dr. Krad creates a flap in your cornea and then he uses an excimer laser to reshape your cornea. The LASIK procedure takes only minutes for each eye and Dr. Krad performs it on an outpatient basis, which means you’re free to go home afterward.
The best news is that once Dr. Krad reshapes your cornea, the results are permanent. This doesn’t mean that you won’t need reading glasses down the road, but it does create a new corneal shape that lasts.
