[Radial keratotomy for the treatment of myopia].
210 eyes were performed radial keratotomy for treatment of myopia of mean -5.65D. The central clear zone was 3mm-4mm in diameter, and 4, 6, 8 or 12 incisions were made. The depth of cut was estimated at 90%-95% of the corneal thickness. After a mean follow-up of 15.4 months, myopia was reduced by an average 4.99D, keratometric corneal refractive power by 3.91D, and 42.4% of the eyes became emmetropic. The complications included corneal microperforation in 4.3%, visual fluctuation in 36.2%, glare in 11.9%, overcorrection from +0.75 to +1.50D in 3.8%, and undercorrection from -1.00 to -5.25D in 20.0% of the eyes. The rate of endothelial loss averaged 5.9% in the central and 6.0% in the peripheral area of the cornea.
