Correction of myopic anisometropia with photorefractive keratectomy in 15 eyes.

Photorefractive keratectomy (PRK) was performed to correct postoperative myopia and anisometropia in 15 eyes: seven eyes following IOL implantation, six eyes after radial keratotomy, and two eyes after corneal transplantation. The results for the first IOL group were similar to simple PRK in cases of myopia. The RK group showed a tendency for overcorrection. Penetrating keratoplasty eyes showed, after 6 months, changing and moderate haze.
