摘要
为评价准分子激光角膜原位磨镶术治疗近视的疗效， 将１２４０ 例 （２４８０ 眼） 近视眼患者 （－ １．２５～－２５．００Ｄ） 分为３ 组： １组为－ １．２５～－ ６．００Ｄ， ２ 组为－ ６．１５～－ １０．００Ｄ， ３组为－ １０．１５～－ ２５．００Ｄ， 均采用准分子激光角膜原位磨镶术（ＬＡＳＩＫ） 进行治疗， 术后平均随访１８ 个月（６～３６个月）， 并对资料进行分析。结果显示： 术后１８个月屈光度与预矫相差在±０．５０Ｄ和±１．００Ｄ以内者１ 组为８５％ 和９６％ ； ２ 组为７５％ 和９０％ ； ３ 组为３５％ 和７５％ 。裸眼视力０．５ 和１．０ 者１ 组为９９％ 和８７％ 。２ 组为９３％ 和７２％ ； ３ 组为７０％ 和３２％ 。其中２５２ 眼进行了再次手术， ２０ 眼因各种原因致矫正视力下降２行或更多。因此我们认为ＬＡＳＩＫ 可有效地治疗－ １．２５～－ ２５．００Ｄ的近视眼而无严重并发症发生。患者的合作以及手术技巧和激光设备及其程序的不断改进有助于进一步提高手术的预测性。
To evaluate the therapeutic effects of excim er laser in situ keratom ileusis (LASIK) in the treatm ent ofm yopia, 2480 eyes of1240 m yopic patients w ho received LASIK w ere studied. The patients w ere divided into 3 groups according to the preoperative diopters (- 1.25 to - 6.0 OD, - 6.15 to - 10.0 OD, - 10.15 to - 25.0 OD) .The m ean follow -up w as 18 m onths (6 to 36 m onths) and the results w ere statistically analyzed. Eighteen m onths after surgery, 85 % and 96 % ofthe eyes show ed the refraction of ±0.5 ODand ±1.0 OD respectively in the firstgroup, 75 % and 90 % in the second group, 35 % and 75 % in the third group. The uncorrected visualacuities of0.5 and 1.0 accounted for 99 % and 87 % ofthe eyes respectively in the first group, for 93 % and 72 % in the second group, for 70 % and 32 % in the third group, respectively. 252 eyes w ere retreated w ith LASIK. Tw enty eyes losttw o orm ore lines ofthe best corrected visualacuity due to various causes. The resultsindicated thatLASIK can treatm yopia of- 1.25 to - 25.0 OD effectively w ithout severe vision com plications.The patient cooperation and the im provem ent ofsurgicaltechniquesand lasernom ogram w illhelp to im prove the predictability and stability of outcom e.
