Laser in situ keratomileusis (LASIK) combines a 30-year-old established lamellar keratectomy procedure with the precision of the photoablating excimer laser. This procedure is used to reduce moderate myopia and astigmatism.
LASIK was performed on 130 eyes and the visual outcome was evaluated.
A total of 63 male eyes and 67 female eyes (mean age, 36 years: range, 19 to 57 years) were evaluated, for a total of 130 eyes. The mean preoperative spherical equivalent was -7.450 (range, -3.12 to -13.87 D). The mean preoperative cylinder was -1.15 DC (range, plano to -4.50 DC). For 130 eyes, after 1 month the mean postoperative spherical equivalent was -0.53 D (range, +2.00 to -4.62 D), and the mean postoperative cylinder was -0.33 DC (range, plano to -2.75 DC). For 82 eyes, after 3 months the mean postoperative spherical equivalent was -0.83 D (range, +1.00 to -4.67 D), and the mean postoperative cylinder was -0.41 DC (range, plano to -2.00 DC). For 49 eyes, after 6 months the mean postoperative spherical equivalent was -0.84 D (range, +1.00 to -8.25 D), and the mean postoperative cylinder was -0.43 DC (range, plano to -1.75 DC). For 20 eyes, the mean postoperative spherical equivalent after 12 months was -0.72 D (range, +0.50 to -2.50 D), and the mean postoperative cylinder was -0.53 DC (range, plano to -2.50 DC).
LASIK appears to be an effective treatment for the reduction of moderate-to-high myopia.
准分子原位角膜磨镶术(LASIK)将一项有30年历史的板层角膜切除术与光消融准分子激光的精确性相结合。该手术用于降低中度近视和散光。
对130只眼实施LASIK手术并评估视觉效果。
共评估了63只男性眼和67只女性眼(平均年龄36岁:范围19至57岁),总计130只眼。术前平均等效球镜度为-7.450(范围-3.12至-13.87 D)。术前平均柱镜度为-1.15 DC(范围平光至-4.50 DC)。130只眼在术后1个月时,术后平均等效球镜度为-0.53 D(范围+2.00至-4.62 D),术后平均柱镜度为-0.33 DC(范围平光至-2.75 DC)。82只眼在术后3个月时,术后平均等效球镜度为-0.83 D(范围+1.00至-4.67 D),术后平均柱镜度为-0.41 DC(范围平光至-2.00 DC)。49只眼在术后6个月时,术后平均等效球镜度为-0.84 D(范围+1.00至-8.25 D),术后平均柱镜度为-0.43 DC(范围平光至-1.75 DC)。20只眼在术后12个月时,术后平均等效球镜度为-0.72 D(范围+0.50至-2.50 D),术后平均柱镜度为-0.53 DC(范围平光至-2.50 DC)。
LASIK似乎是降低中高度近视的一种有效治疗方法。
