Keratoconus
Keratoconus occurs when the cornea starts to thin and bulge out like a cone. If left untreated, Keratoconus can degrade your vision.
Keratoconus Symptoms
- Blurred vision
- Poor night vision while driving
- Double vision
- Frequent eye rubbing
- Halos and glare around light
- Frequent changes in eyeglasses or contact lens prescriptions
Keratoconus Treatment Options
Refractive errors caused by keratoconus can sometimes be corrected by prescription glasses or hard contact lenses. If keratoconus is progressing, corneal crosslinking can be done to help strengthen the cornea and prevent the keratoconus from getting worse. However, if the keratoconus has caused corneal scarring that limits vision, this may require a full-thickness corneal transplant. This means that the damaged cornea gets replaced by donated corneal tissue in a procedure called Penetrating Keratoplasty (PKP).
