or myopia developed bacterial keratitis, one from Staphylococcus epide
rmidis and the other with a negative culture. Both were treated with t
opical antimicrobial agents. One eye recovered an uncorrected visual a
cuity of 20/20. The other was left with a moderate subepithelial scar
and an uncorrected visual acuity of 20/150.
