联合使用自控微型板层角膜成形刀及准分子激光机,先做一个以鼻侧为基底的角膜瓣,然后再于瓣下行基质内光学切削治疗的方法,治疗50例58只超高度近视眼。术前平均屈光度为-19.29±3.88D(-15.37～-36.00D),随访三个月以上者,其术后平均裸眼视力为0.61±0.27,其中≥0.5者占67.24%,≥0.8者占32.76%;术后平均屈光度为-0.49±3.01D,其中屈光度在±1.00D 内者占51.72%,±2.00D 内者占75.86%。结果表明此手术对超高度近视矫治能力及可预测性优于共它角膜屈光手术,但其稳定性、潜能及安全性有待于长期观察和进一步研究。 Joint use of self-controlled micro-layer corneal knife and excimer laser machine, the first to do a nasal flaps based on the corneal flap, and then in the flap down the matrix optical cutting treatment of 50 cases of 58 super-high myopia. The average preoperative refractive power was -19.29 ± 3.88D (-15.37 ~ -36.00D) .All patients were followed up for more than three months, the average postoperative uncorrected visual acuity was 0.61 ± 0.27, of which ≥0.5 accounted for 67.24%, ≥0.8 accounted for 32.76 %. The average postoperative refractive power was -0.49 ± 3.01D, of which 51.72% were within ± 1.00D and 75.86% within ± 2.00D. The results show that the surgical treatment of ultra-high myopia ability and predictability is better than total corneal refractive surgery, but its stability, potential and safety to be long-term observation and further study.
