A healthy cornea is round like a ball. If the cornea begins to thin, it can start to bulge into a cone shape. This is a condition called keratoconus. Due to the cone shape of the cornea, the light bends irregularly and as it hits the back of the eye (retina), defocus and blur will distort vision. Many times glasses are not able to increase vision due to the irregularities on the cornea. There is a loss of best-corrected vision. Fortunately, the professionals at Dr. Landrio & Associates can treat the condition.
There are several treatments for keratoconus. The treatment method that your optometrist chooses would depend on the severity of your condition. In some cases, your eye doctor will need to try a few treatment methods until they find the one that is the most effective.
Gas-Permeable Contact Lenses
Gas-permeable contacts are rigid; therefore, they will hold your cornea in a round shape. This will keep it from bulging. Also, gas-permeable lenses provide sharper vision than soft lenses, which will help you see more clearly.
Piggyback Contacts Lenses
Trying to fit a round contact over a cone-shaped cornea can cause discomfort. A piggyback contact involves fitting a soft lens over the cornea and then a gas-permeable lens over it. The soft lens will provide the cushion necessary to make the contacts comfortable.
Hybrid lenses are rigid in the center, and the outer area is soft. If you find gas-permeable lenses to be uncomfortable, hybrid lenses are an option.
Prosthetic lenses are often prescribed for patients with advanced keratoconus. To make these contacts, a 3-D scan of your eye would be taken so that every curvature and irregularity is mapped. This allows your optometrist to have a lens designed that fit your eyes perfectly.
There are two types of crosslinking. Epithelium-off involves removing the outer layer of the cornea to allow vitamin D and riboflavin to enter the cornea and is then activated with a UV light. The second type is epithelium-on. This method takes longer for the riboflavin to penetrate the cornea; however, there is less risk of infection, and your vision will be restored faster.
