Comparison of best spectacle-corrected logMAR visual acuities in our PRK study group (A) compared with a group of noncompliant or late diagnosis anisometropic amblyopic children (P = .003, Fisher’s exact test) (B) and a group of compliant anisometropic amblyopic children (P = .26) (C). Improved visual acuity after treatment is demonstrated as a point below the line. Note how the compliant group uniformly experienced improved visual acuity and the noncompliant group almost uniformly experienced no change in the visual acuity. Most children in the PRK group experienced some improvement in visual acuity, though not as marked as the compliant group.
