Keratoconus is an eye condition that causes vision loss as the normally round cornea thins and bulges into a cone shape. This irregular shape prevents light from properly focusing on the retina, resulting in significant vision impairment. If you or a loved one has been diagnosed with keratoconus, you likely have many questions. We would like to answer some of the frequently asked questions about living with keratoconus.
What Causes Keratoconus?
While the exact cause is unknown, keratoconus tends to occur in those with certain genetic factors. Eye rubbing, asthma, and allergies may also play a role. The cornea changes shape over time, resulting in astigmatism, nearsightedness, and light sensitivity. Glasses can initially compensate, but vision continues deteriorating.
At What Age Does Keratoconus Occur?
Keratoconus typically begins during the teen years and progresses until the mid-30s. However, it can occur at any age. Early diagnosis and treatment are key to slowing progression. Routine eye exams can detect changes in corneal shape before major vision loss.
What Are the Treatment Options?
In the early stages, custom eyeglasses or contact lenses can correct vision fairly well. A procedure called corneal collagen cross-linking uses UV light to strengthen the cornea and slow progression. If vision worsens, corneal ring implants or corneal transplants may be required.
Will Keratoconus Affect My Peripheral Vision?
The central cornea is most impacted by keratoconus, so peripheral vision is typically unaffected. However, there may be some difficulty with activities requiring good central vision like reading and driving.
Can Keratoconus Be Passed to My Children?
Keratoconus can be hereditary. Children of an affected parent have a 50% chance of developing the condition. Be sure to schedule annual eye exams for early detection.
How Often Do I Need Eye Exams?
Those with keratoconus require more frequent exams to monitor vision changes—usually every six months. Your optometrist can recommend the ideal exam schedule based on your specific case.
Can I Still Wear Contact Lenses?
Specialized rigid gas permeable (RGP) lenses can vastly improve vision in many keratoconus patients. Your optometrist can determine if you are a candidate for these custom lenses.
When Should I Consider a Corneal Transplant?
If vision deteriorates to the point where even rigid contacts cannot provide functional vision, a corneal transplant may be necessary. Your doctor can advise you on when a transplant is appropriate based on exam findings.
