放射状角膜切开术治疗圆锥角膜

Radial keratotomy for keratoconus

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。

15 consecutive eyes of 13 patients with kerato- conus were treated with radial keratotomy and follo- wed up periodically about 1 year.The visual acuity of all eyes was improved significantly,in the early stage after surgey.The 12 eyes were examined one year postoperatively,1 eye maintainning good result,5 eyes obtainning some improvement of vision and flatt- ening of central cornea,6 eyes of which 4 had adv- anced corncal cones gainning no visual benefit from the surgery.Radial keratoto my appears to be effec- tive in early case of keratoconus,however the long- term result is still not known.
