Better Vision Overnight
Orthokeratology is a non-surgical way to improve your vision while you are asleep. Ortho-k as it is known is the process of wearing rigid gas-permeable contact lenses at night to reshape the cornea and provide clearer vision during the day. The optometrists at Advanced Eye Care Associates in Providence are experts at using orthokeratology as a tool for better sight.
How Does Orthokeratology Work?
Ortho-k for eye care is often compared to orthodontia for the teeth. Patients wear gas-permeable contact lenses while they sleep to flatten the cornea and reshape it for better vision.
The cornea is the clear tissue at the very front of the eye that lets light in and focuses it on the retina. Patients with myopia, or nearsightedness, can see fairly well up close but objects in the distance are blurry. The vision problem comes because the cornea is misshapen. While nearsightedness can be corrected with glasses or contact lenses or even surgery, ortho-k works at night and the effects last during the day.
How Long Does Orthokeratology Take to See Results?
Your optometrist may fit you with a series of lenses to wear before achieving the final vision correction. This process can take a few weeks. Once your eye doctor is pleased with your vision you will be fitted with a retainer type of lens to wear. Much like retainers after orthodontia, the retainer lens is there to hold the new shape of your cornea. Orthokeratology is not a permanent vision solution on its own. Without the use of a retainer lens and good follow-up care from your optometrist, the cornea can return to its previous shape. Ortho-k eye care can be maintained indefinitely.
Is it Difficult to Sleep in Contact Lenses?
At the beginning of orthokeratology treatment many patients report that they are aware they have lenses in their eyes as they begin to go to sleep. But the eye quickly becomes used to the sensation of the lens. While a gas-permeable lens is more rigid than a standard soft contact lens, it does allow oxygen into the eye.
