摘　　要：目的研究单眼视（monovision，MV）原理在高度近视白内障患者中应用的效果。方法高度近视伴白内障54例，行白内障超声乳化并单焦点人工晶状体植入术，应用单眼视原理，使术后主导眼（优势眼）形成正视，非主导眼保留-1．0D以上的近视，按屈光参差的程度分为3组，检查术后3个月双眼裸眼远视力、近视力、立体视及对比敏感度，并进行人为加镜形成双眼平衡全矫状态加以对照。最后进行视功能损害眼病患者生存质量量表问卷及满意率调查。结果远视力及立体视3组比较差异无统计学意义（P〉0．05），近视力比较3组单眼视矫正患者均明显优于完全矫正，差异有统计学意义（P〈0．05）。在100％对比度明视白背景下，第3组患者（屈光参差≥2．75D）单眼视矫正视力低于完全矫正，差异有统计学意义（P〈0．05）。明暗视时，红蓝背景下敏感度检查比较差异无统计学意义（P〉0．05）。术后问卷及满意率调查，3组患者间差异无统计学意义（P〉0．05）。结论单眼视原理应用于高度近视伴白内障患者的屈光矫正，可有效提高患者远、近视力，非主导眼宜保留-1．5D以上的近视，具体情况还需根据患者个体差异而定。屈光参差≥2．75D的患者术后需注意夜间眩光现象。Objective To evaluate the clinical effects of monovision principle in high myopia cata- ract patients after application of the operation. Methods 54 cases of high myopia accompanied with cataract received phacoemulsification and single focus intraocular lens implantation, applying the principle of monovi- sion. they were designed to yield 0D for master （dominant） eyes ,and - 1.0D or more myopia for nondomi- nant eyes. According to anisometropia, they were divided into three groups. The far and near vision , stereo- scopic vision, contrast sensitivity were checked 3 months after operation. The patients were corrected in both of the eyes by glasses as a control group, questionnaire survey and satisfaction investigation were done for the patients. Results There were no significant difference between the 3 groups in far vision or stereoscopic vi- sion （ P 〉 0.05 ）. For near visual acuity compared, three groups of monovision patients were significantly bet- ter than the complete correction patients, the difference was statistically significant （ P 〈 0. 05 ）. Under 100% contrast high brightness（250cd/m2） white background, the corrected visual acuity in the third group of monovision patients （anisometropic≥2.75D） were less than the completely corrected group, there was a statistically significant difference （ P 〈 0.05 ）. Under 250 cd/m2 and 25 cd/m2 brightness red and blue background, the contrast sensitivity showed no significant difference（ P 〉 0.05）. In the questionnaire and the satisfaction rate survey, there was no significant difference between the three groups （ P 〉 0.05 ）. Con- clusion Application of monovision principle in refractive correction of high myopia patients with cataract, which can effectively improve far, near vision. Non-dominant eye should retain over - 1.5D myopia based on individual difference. Patients with anisometropic ≥ 2.75D should pay attention to night glare phenomenon.
