为评价微型角膜刀板层角膜成形联合准分子激光角膜切削术(MLK-E或LASLK)治疗高度近视的效果和安全性,利用微型角膜刀作一带蒂角膜瓣,在其下用schwindKeratomⅠ型准分子激光机进行PRK激光切削,共治疗了30例47眼,术前屈光状态<-15D的Ⅰ组共35眼,屈光度为-10.20±2.04D,最佳矫正视力为0.92±0.26(0.4—1.5);等球镜≥-15D的Ⅱ组共12眼,屈光度平均为-17.64±1.83D,最佳矫正视力为0.42±0.23(0.1—0.8)。散光最高为4.5D。结果:术后3个月随访:Ⅰ组:屈光度平均为-0.48±0.52D(-1.75—+0.50D),裸眼视力34眼(97%)达到0.5以上(另1眼裸眼视力等于术前),25眼(71.4%)裸眼视力达到术前最佳矫正视力。Ⅱ组:屈光度平均为-1.44±1.97D(-5.50—+1.25D),8眼(66.7%)裸眼视力达到术前最佳矫正视力。是一种安全有效的高度近视治疗方法。
To evaluate the efficacy and safety of microkeratome keratorefractive keratorectal excimer laser keratomileusis (MLK-E or LASLK) in the treatment of high myopia, a miniature corneal knife was used to make a pedicled corneal flap under which schwind Keratom type I excimer Laser machine PRK laser cutting, a total of 47 cases were treated in 30 cases, preoperative refractive status <-15D group Ⅰ a total of 35 eyes, the refraction was -10.20 ± 2.04D, the best corrected visual acuity was 0.92 ± 0.26 (0.4-1.5). There were 12 eyes in group Ⅱ with spherical ≥ -15D. The average diopter was -17.64 ± 1.83D and the best corrected visual acuity was 0.42 ± 0.23 (0.1-0.8). Astigmatism up to 4.5D. Results: After 3 months of follow-up, in group Ⅰ, the average refractive power was -0.48 ± 0.52D (-1.75- + 0.50D) and the uncorrected visual acuity was above 0.5 (97%) Eye uncorrected visual acuity equal to preoperative), 25 eyes (71.4%) uncorrected visual acuity reached the best corrected visual acuity before surgery. In group Ⅱ, the average refractive power was -1.44 ± 1.97D (-5.50- + 1.25D), and the uncorrected visual acuity of 8 eyes (66.7%) reached the best corrected visual acuity before operation. Is a safe and effective treatment of high myopia.
