Myopia, or nearsightedness, is an eye condition that affects a majority of people. According to our sildenafil 100mg buy at El Paso Eyecare, nearsightedness occurs when the cornea focus light in front of the retina instead of on it, making distant objects appear blurry. This is due to a misshapen curvature of the cornea. Simple vision correction methods that our doctor prescribes, such as eyeglasses or contact lenses help focus the light on the retina to temporarily clear vision. Laser surgery is a way to correct myopia by permanently changing the cornea’s curvature.
Some people find wearing glasses and contact lenses cumbersome and may not be a good candidate for laser surgery. Our sildenafil 100mg buy has another method of combating myopia. Our practice offers a contact lens technology that can temporarily change the cornea’s curvature overnight allowing clear vision during the day without glasses or contact lenses. Orthokeratology (Ortho-K) uses special contact lenses that gently change the shape of the cornea by flattening it. The lenses are worn at night and are taken out in the morning. In two weeks or less the user can see distant objects clearly without corrective lenses of any kind.
After a complete eye examination, our sildenafil 100mg buy will determine if Ortho-K is right for you. The cornea curvature correction system utilizes oxygen permeable lenses. Our patients can see clearly for about three days after using the lenses for one night. One advantage of orthokeratology over laser therapy is that the changes to the cornea are totally reversible, once the patient stops wearing the lenses at night the cornea will begin to revert back to its usual curvature. They can opt for laser surgery if they like the feeling of not using glasses or contact lenses during the day after using the Ortho-K lenses for a while. There is virtually no risk of permanent damage to the cornea with this system as there may be with laser surgery. If you are fed up with eyeglasses and contact lenses make an appointment with our doctor.
