Keratoconus is a condition characterized by a change in the curvature of the cornea, the clear clear outer layer of the eye. The cornea is typically round, but in keratoconus, it becomes more elongated, like a spoon. This change in curvature can cause various problems, including blurred vision, difficulty seeing in low-light conditions, and an increased risk of refractive errors.
The cause of keratoconus is unknown, but it is often linked to genetics and aging. Risk factors include diabetes, obesity, excessive exposure to ultraviolet (UV) light, and certain medications.
Symptoms of keratoconus include:
Blurred or dim vision
Difficulty seeing in low-light conditions
Night vision problems
Eye strain
Headaches
Difficulty driving at night
Diagnosis of keratoconus is typically made through a physical examination and a slit lamp exam. During the slit lamp exam, the doctor shines a special type of light into the eye to check the curvature of the cornea.
Treatment for keratoconus depends on the severity of the condition. Treatment options may include:
Wearing corrective lenses, such as glasses or contact lenses
Anti-reflective coatings on lenses to reduce glare
Laser refractive surgery to reshape the cornea
Ortho-k lenses, which are rigid contact lenses that can be worn overnight
Corneal transplants, which are a surgical procedure to replace a damaged cornea with a healthy one
