本文报道193nm准分子激光角膜切削术（PRK）矫正139例近视、屈光度为-2．25～－9．00D的257只眼的疗效，随访6个月至1年。术后1年随访时，低中度组（≥－6．00D）81．25％的屈光度在±1．00D以内；高度组（＞－6．00D）则为69．57％。术后裸眼视力≥0．5和≥1．0者，低中度组为97．5％和77．5％；高度组为100％和73．3％。术后无3级及其以上的、具有临床意义的角膜上皮下混浊。看来，PRK为目前矫正近视的一种安全有效的术式。
This article reports the results of 193 keratorectal excimer laser keratectomy (PRK) correction of 139 cases of myopia, refraction of -2.25 ~ -9.00D 257 eyes of curative effect, followed up for 6 months to 1 year. At 1 year follow-up, 81.25% of the patients in the low-medium group (≥-6.00D) had refraction within ± 1.00D and 69.57% in the height group (> -6.00D). Postoperative uncorrected visual acuity ≥0.5 and ≥1.0 were 97.5% and 77.5% in the low-medium group and 100% and 73.3% in the high-group. No grade 3 and above, with clinical significance of corneal subcutaneous turbidity. It seems, PRK is currently a safe and effective surgical correction of myopia.
