目的:探讨准分子激光原位角膜磨镶术(LASIK)治疗近视合并中高度散光的安全性和有效性。方法:应用德国Wavelight公司的鹰视准分子激光治疗系统对62例83眼近视合并中高度散光(≥-2.00D)患者进行LASIK治疗。随访6mo,比较手术前后的视力、屈光度、散光及其散光轴位的变化。结果:术后6mo,视力在0.8以上(≥0.8)和1.0以上(≥1.0)者分别为78%和47%,裸眼视力≥术前最佳矫正视力(BCVA)57眼(69%),散光度数在±1.00以内64眼(77%),残留散光平均为-0.80D,散光矫正(±0.50以内)37眼(45%)。结论:LASIK治疗近视合并中高度散光效果明显,患者术后满意度高。

AIM:To investigate the clinical efficacy of laser in situ keratomileusis(LASIK)for myopia combined with medium and high astigmatism.METHODS:Sixty-two myopia patients 83 eyes combined with medium and high astigmatism(≥-2.00D) were treated with LASIK by the excimer laser treatment system of Wavelight company of Germany.Preoperative and postoperative tests included vision,dioptre,astigmatism and the axis of astigmatism.RESULTS:After 6 months’ follow-up,the results showed that vision was over 0.8 in 78% and 1.0 in 47% respectively.The postoperative uncorrected visual acuity better than preoperative best-corrected visual acurity was in 57 eyes(69%).64 eyes(77%) were within ±1.00D of astigmatism.The average residual astigmatism was-0.80D,and 37eyes(45%) residual astigmatism were within ±0.50D.CONCLUSION:The LASIK is an effective treatment for myopia combined with medium and high astigmatism,patients have a high level of satisfaction.
