摘要
目的探讨准分子激光角膜瓣背面磨镶术(LASUK)治疗准分子激光原位角膜磨镶术(LASIK)术后屈光欠矫和回退的疗效。方法对LASIK后屈光欠矫和回退的14例(24眼)施行LASUK,观察术后视力、屈光度、角膜后表面及haze情况。结果术后3个月视力和屈光度趋于稳定,术后无角膜浑浊,无继发性圆锥角膜。术后6个月,裸眼视力≥0.6和≥1.0者分别为24眼(100.00%)和18眼(75.00%)。屈光度介于±1.00D者22眼(91.67%),19眼屈光度介于±0.50D之间,最佳矫正视力无下降者。结论LASUK治疗LASIK术后屈光欠矫是安全有效的。
Objective To evaluate the efficacy of laser in undersurface flap keratomileusis （LASUK） treating for the undercor-rection after laser in situ Keratomileusis. Methods After treated with laser in situ Keratomiieusis （LASIK）, the myopia in 14 patients （24 eyes） was undercorrected. The residual myopia was-1.75D - -4.25D（ average -3.15D±1.05D） and astigmatism -0.50D - -1.25D（ average - 0.78D - 0.35D） , The thickness of central cornew was 425 μm-2.05 μm. All the patients was tveated with laser in undersuface flap Keratomileusis （LASUK） using Nidek EC-5000 cx Ⅱ and Visx star S4. Results The vision and refractive status were statle at 6 months postoperatively. No eye lost best corrected sneller visual acuily, No intraoperative or postoperative complications occurred. At 6 postoperative months, 22 eyes （91.67%） were within ±1.00 diopter, and 19 eyes（79. 17% ）were with in -0.50 diopter. The uncorrected vision was over 0.6 in 24 eyes（ 100% ）,and over 1.0 in 18 eyes （75.0%）. Conclusions The undercorrected myopia after LASIK can be treated with LASUK. It is effective and safe procedure.
