Abstract

Purpose. To analyze the long term effect of our combined technique of radial keratotomy for the surgical correction of myopia. Methods. 378 out of 1200 myopic eyes operated with a personal combined technique of radial keratotomy (go - go back technique; Boll Ocul 70;401,1991) with follow up > 1 year (range 1,5-5 years; mean 3,2 years) were evaluated. Our technique combines 4 or more centrifugal and centripetal incisions. Corneal pachymetry is performed at 8 points in the perioptic zone. The centrifugal incision is 100% of the measured pachymetric value; the centripetal is 90% of the same value. A nomogram with different variables (refraction; corneal thickness, curvature and diameter; age and intraocular pressure) has been developed. Results. Preoperative vs postoperative myopia was - 6.35 ± 2.60 vs - 0.76 ± 1.27 (p 7). 92% of patients achieved 20/40 or better uncorrected visual acuity at all time points. Microperforation rate was <2%. No progressive hyperopia > 1 diopter was found. Conclusions. Our combined technique of radial keratotomy is a safe and reliable method for the surgical correction of myopia. Its effects appear stable during long term follow up.
