Abstract
Eyes (18) [human] were preoperatively evaluated and operated on by the Fyodorov method. Although Fyodorov stated that his formula improves the predictability of radial keratomy, there are no known previously published studies that included it. All omitted the Maklakov measurement of scleral rigidity, although, according to Fyodorov, it may influence the surgical result profoundy. Maklakov measurement of scleral rigidity does not correlate with Schiotz measurement of scleral rigidity. The overall predictability of the formula at 6 to 14 mo. postoperatively was good except in the eyes of a diabetic patient. The formula enables the surgeon to show the patient preoperatively what his likely result will be. Of the 17 eyes, 16 (94%) in the refraction range of -2.00 to -7.50 had a visual acuity of 20/50 or better. The patient satisfaction rate was excellent. There were no important complications. Subjective glare and glare independently measured with the Miller-Nadler glare tester was absent in all tested eyes except 1 eye when it was dilated. Radial keratotomy as described here is safe, effective and reasonably predictable and may be offered to selected patients who have personal requirements that are not fulfilled by standard optical devices.
