Abstract:
The device for central photorefractive keratectomy(CPRK) was recently introduced for the correction of myopia. Of 61 sighted myopic eyes treated by CPRK. there were 21 female and 40 male patients. The eves were classified in the 3 refraction groups. Group I included eyes with myopia ranging from -2.0 to -4.75 D (3 eyes); Group II eyes with myopia ranging from -4.0 to -5.75 D (17 eyes); and Group III eyes with myopia ranging from -6.0 to -9.0 D (41 eyes). On the sixth postoperative months, mean skiascopic correction of the group I, II, and Ill were 2.30 D, 4.19 D and 6.01 D, respectively, and mean reduction of keratometric diopter of the group I, II and Ill were 2.28 D, 2.99 D and 3.26 D, respectively. Six months postoperatively, mean uncorrected visual acuity of the group I, II and Ill were 20/30, 20/25 and 20/40, respectively. The CPRK was better to the correction of moderate and high myopia than Excimer laser RK(Radial Keratotomy) or RK by diamond knife.
