Keratoconus doesn’t always cause eye pain. However, its symptoms can cause discomfort and other problems. The most common symptoms of Keratoconus include astigmatism, degrading vision quality, and corneal thinning, bulging, or rounding. Some individuals may experience corneal scarring and find themselves unable to use contact lenses. These individuals may require a corneal transplant to correct this problem.
If you have Keratoconus and experience sudden pain in your eyes, you should consult with your Keratoconus specialist immediately.
