Patients who don’t follow their doctor’s instructions for wearing their contact lenses are at higher risk of developing infectious corneal ulcers. If an ulcer is out of the visual axis, a remaining scar will not affect the vision. But a central ulcer, like this one, is at high risk of developing permanent loss of vision to some degree. Culturing becomes important in case chosen treatment isn’t effective. In addition to proper antibiotic treatment, the best chance of minimizing the scar is the use of an amniotic membrane and possibly the very judicious use of topical steroids as the infection is controlled.
