To evaluate the safety and efficacy of photorefractive keratectomy for correcting residual myopia and astigmatism in patients who previously underwent radial keratotomy or penetrating keratoplasty.
Treated 15 eyes presenting with initial myopia between -5.00 D and -12.00 D using photorefractive keratectomy (PRK) at least 6 months after radial keratotomy (RK), with 6 to 24 months of follow-up.
Treated 5 eyes with PRK for residual ametropia after penetrating keratoplasty (PKP), monitoring outcomes for up to two years.
In RK-treated eyes, mean spherical refraction improved from -4.00 D pre-PRK to -0.52 D post-PRK, and mean cylinder improved from +1.25 D to +0.73 D.
The incidence of post-procedure complications, including corneal haze, was extremely low in both RK and PKP groups.
