目的比较假性晶状体患者常规单视矫正主视远视力与交叉单视矫正非主视远视力的视力表现及患者满意度。方法对2009年11月至2012年8月在建国大学医学中心接受不同靶点单焦点人工晶状体植入术的59例患者进行前瞻性随机研究。双侧白内障术前及术后2个月检查：屈光不正、双眼未矫正距离视力（UCDVA）、未矫正近视力（UCNVA）、最佳矫正视力（BCVA）、立体视觉。所有患者均完成术后眼镜依赖及患者满意度问卷调查。结果常规单视组28例，交叉单视组31例。两组术后UCDVA、UCNVA、BCVA及立体视觉均无显著差异。此外，两组患者对近、远视力和眼镜依赖的满意度无显著差异。结论交叉单视与常规单视的临床效果无显著差异。因此，对于考虑双侧白内障手术的患者，交叉单视也是矫正术后老花眼的一个有价值的选择。
Aims To compare the visual performances and patient satisfactions of conventional monovision, which corrects the dominant eye for distance vision, and crossed monovision, which corrects the non-dominant eye for distance vision in patients with pseudophakia.Methods This prospective randomised study was conducted in 59 patients who underwent implantation of different targets of monofocal intraocular lens for each eye at Konkuk University Medical Center between November 2009 and August 2012. The following were examined before bilateral cataract surgery and 2 months after the surgery: refractive error, binocular uncorrected distance visual acuity (UCDVA), uncorrected near visual acuity (UCNVA), best corrected visual acuity (BCVA) and stereopsis. Questionnaires to evaluate postoperative spectacle dependence and patient satisfaction were completed by all patients.Results The conventional monovision group and the crossed monovision group were composed of 28 and 31 patients, respectively. There were no significant differences in postoperative UCDVA, UCNVA, BCVA and stereopsis between the two groups. In addition, patient satisfaction with near and distant vision and spectacle dependence were not significantly different in the two groups.Conclusions The clinical results of the crossed monovision were not significantly different from the results of conventional monovision. Therefore, crossed monovision can also be a valuable option for correcting postoperative presbyopia in patients considering bilateral cataract surgery.
