[Comparative characterization of the results of new and standard methods of keratotomy].

The authors compare the efficacies of the traditional "Russian" radial keratotomy and the new method of making radial keratotomic incisions with evenly deep profiles. Keratotomy was carried out in 60 patients (120 eyes) with similar binocular myopia. On one eye the traditional "Russian" method was used, on the other the new method.

[Asymmetric radial keratotomy for low-grade myopia].

Thirty patients (47 eyes) underwent a radial keratotomy for low myopia (from -0.75 to -2.5 D).

New technique for knife and radial keratotomy.

Background: Radial keratotomy is the most popular method of surgical correction of myopia, but requires further improvements. This study presents a new knife design for radial keratotomy.

Methods: Radial keratotomy was performed on 120 eyes of 60 patients with myopia.

[Prevention of postoperative inverse astigmatism during radial keratotomy].

Seventy eight patients (156 eyes) were treated by radial keratotomy. Patients with spherical axial myopia were selected (including 39% of physiological astigmatism cases). After radial conventional technique the against-the-rule astigmatism > 1.

[Management of corneal microperforations during radial keratotomy].

Corneal microperforations induce a corneal astigmatism since refractive effect is increased on the perforated meridian. To counteract this induced refractive error, we performed "flag" or tangenital incisions on the perpendicular meridian.
