Chances are you scheduled an appointment to see your optometrist because you were not seeing as well as you used to. But, instead of getting a simple prescription for glasses or contacts, you received a diagnosis of keratoconus, a progressive condition that poses a threat to your vision. Now you’re left wondering: what is keratoconus and what treatment options are available to me?
In simple terms, keratoconus is a condition where the typically round cornea becomes thinner and takes on a cone shape. This alteration in form affects how light is directed onto the retina, leading to blurred and distorted vision.
Treatment for keratoconus varies depending upon the severity of your condition and the rate of progression. The goals of treatment are to slow the progression of the disease and to improve your vision.
There are several things you can do to help slow the progression of keratoconus.
Rubbing your eyes has been associated with accelerated progression of keratoconus, so it is important that you stop this habit. Rubbing your eyes too often or too hard can scratch or damage the cornea and lead to further thinning of the cornea. If your eyes feel uncomfortable, consider using lubricating drops instead of rubbing them. Additionally, antihistamine eye drops can be effective in preventing and treating itchy eyes triggered by allergies.
Corneal topography provides a detailed image that shows the contour of the cornea, serving as a crucial tool in the treatment of keratoconus. Through topography scans, your optometrist can track any alterations in the curvature of the cornea.
Ill-fitting lenses may rub against the affected area of the cornea, exacerbating symptoms by further irritating the already delicate cornea. Getting an evaluation every 6-12 months can help ensure that your lenses maintain a proper fit.
If your keratoconus has advanced, corneal cross-linking is a highly effective procedure for slowing its progression. During this in-office treatment, the cornea is soaked in riboflavin (vitamin B2) eye drops and exposed to ultraviolet light. This process strengthens the cornea, preventing further alterations in its shape.
The severity of your disease will determine the best options for you.
In the early stages of keratoconus, your vision can often be corrected with glasses or soft contact lenses to treat nearsightedness and astigmatism.
As keratoconus progresses, specially fitted contacts are needed to provide better vision. These include gas permeable lenses,
hybrid lenses or
scleral lenses.
For the majority of individuals diagnosed with keratoconus, a scleral lens is the best option for better vision. Unlike traditional lenses, a scleral lens is a large diameter gas permeable lens that arches over the cornea, resting on the less sensitive sclera. This innovative design offers a seamless refractive surface, alleviating discomfort by alleviating pressure on the cornea. Scleral lenses also have a fluid layer that ensures the eye remains hydrated and increases the comfort of the lens. This fluid layer plays a crucial role in evening out any irregularities in the cornea's shape, thereby enhancing overall vision quality.
Other Treatments
In less than 10% of individuals with keratoconus, the cornea may eventually become too scarred, making it challenging to wear contact lenses. For these individuals, corneal transplant surgery might be necessary.
