单眼视LASIK治疗伴有老视的屈光不正临床观察

目的:探讨单眼视准分子激光原位角膜磨镶术(单眼视LASIK)治疗伴有老视的屈光不正对患者视觉质量、生活质量的影响。方法:屈光不正伴老视的患者172例中124例施行单眼视LASIK(主视眼按最佳矫正远视力完全矫正,非主视眼近视者低矫-0.75~-2.00D,远视者过矫0.75~2.00D),35例放弃手术,13例患者双眼全部矫正。观察术后1d;1wk;3mo时的检查结果。结果:术后3mo单眼视LASIK组124例患者双眼远视力0.7~1.2,双眼近视力J1~J3。无因为难以耐受的不适而需要戴镜补充矫正或再次手术者。双眼完全矫正组术后双眼远视力0.7~1.2,双眼近视力J3~J6,8例(62%)视近困难,需配近用眼镜。结论:单眼视LASIK治疗伴有老视的屈光不正安全有效。单眼视治疗在设计手术方案时需根据患者年龄及调节能力、近附加度数、阅读距离、工作性质等综合考虑。

Clinical observation of monovision with LASIK for correction of refractive errors with concomitant presbyopia

AIM:To evaluate the effectiveness of monovision with LASIK (MV-LASIK) for correction of refractive errors with concomitant presbyopia.METHODS: A total of 124 patients were treated with MV-LASIK: the dominant eyes were treated according to the best corrected vision, and the nondominant eyes of myopia patients were undercorrected -0.75-2.00D, and the hypermetropia was overcorrected 0.75-2.00D. Thirty-five patients gave up the surgery, and 13 patients treated with LASIK had refractive errors of both eyes corrected. The subjects were examined at 1 day, 7 days and 3 months after surgery.RESULTS: In the MV-LASIK group, the uncorrected distance binocular vision was 0.7-1.2, and the near binocular vision was J1-J3 at 3 months after surgery. Nobody needed reading spectacles or to be treated again due to unbearable discomfort or difficulty in reading. In the completely corrected LASIK group, the postoperative uncorrected distance binocular vision was 0.7-1.2, and the near binocular vision was J3-J6 at 3 months after surgery. Eight patients (62%) needed reading spectacles.CONCLUSION: MV-LASIK is safe and effective for correction of refractive errors with concomitant presbyopia. It is very important that the program should be designed according to patient's age, amplitude of accommodation, near addition and reading distance.
