以放射状角膜切开术治疗13例(15只限)圆锥角膜患者。术后近期内患者视力均得到较大改善。12只眼经1年随访,1只眼视力显著提高,5只眼视力和角膜圆锥有不同程度改善。以上6只眼中,4只眼为较早期圆锥角膜。6只限无效,其中4只眼术前为晚期圆锥角膜。并发症包括术中角膜穿孔5只眼、眩光2例、视力波动3例。提示放射状角膜切开术治疗早期圆锥角膜有一定效果,但远期疗效有待进一步随访。 Thirteen patients (15 limited) keratoconus were treated with radial keratotomy. The patient’s visual acuity has been greatly improved in the near future. After 12 eyes were followed up for 1 year, visual acuity was significantly increased in 1 eye, 5 eyes and corneal visual acuity improved to varying degrees. Of the 6 eyes above, 4 eyes were earlier keratoconus. 6 invalid only, of which 4 were preoperative keratoconus late. Complications included corneal perforation in 5 eyes, glare in 2 and visual acuity in 3. Prompted radial keratotomy for early keratoconus has some effect, but the long-term efficacy needs further follow-up.
