Abstract

PURPOSE
To report the long-term results concerning refractive changes after radial keratotomy in 6 eyes of 3 patients.
CASE SUMMARY
We observed 3 patients who underwent radial keratotomy over 25 years previously. The positive effect of this surgery on the correction of refractive error decreased with increasing post-surgery time and myopic refractive errors accompanying astigmatism recurred. On average, refractive errors improved to 3.375 diopter (D) and corneal power improved to 2.954 D; in all cases, uncorrected visual acuities were not significantly improved.
CONCLUSIONS
The effect of radial keratotomy on the correction of refractive errors decreased with time due to regression; myopic refractive errors recurred in the long-term.
