背景:针对眼镜独立性,传统的人工晶状体单视已广泛应用于近视患者的双侧单焦点人工晶状体植入术。然而,交叉的单视动物,即矫正近视眼的优势眼和远视眼的非优势眼,一些研究已经提到高度近视性白内障患者更可取。我们进行了这项研究,以比较临床结果,通过比较患者满意度来评估常规和交叉单视对高度近视假晶状体患者的可行性。视觉功能和眼镜独立性。
方法:将第四十六例高度近视患者分为两组:交叉单视组22例,优势眼屈光度为-2.00屈光度(D),非优势眼屈光度为-0.50D;常规单视组24例,优势眼屈光度为-0.50D,非优势眼屈光度为-2.00D。双眼未矫正远距视力(BUDVA),双眼未矫正近视敏度(BUNVA),双眼矫正远距视力(BCDVA),双眼矫正近视敏度(BCNVA),术后2周检查对比视力和立体视敏度,1个月和3个月。双眼手术后3个月,对患者进行问卷调查,以评估患者的满意度和眼镜独立性。
结果:常规单视组和交叉单视组的BUDVA平均值无显著差异,Bunva,BCDVA,BCNVA2周,术后1个月或3个月(P>0.05)。常规单视组和交叉单视组的双侧对比敏感度或立体功能差异无统计学意义(P>0.05)。患者对近距离和远距离视力的满意度,两组患者眼病依赖及眼病依赖均无显著差异(P>0.05)。
结论:与传统单视技术相比,交叉人工晶状体单视显示出相似的视觉功能,这表明对于考虑双侧白内障手术的高度近视患者,这是改善视觉功能和生活质量的有效选择。

BACKGROUND: Aiming at spectacle independence, conventional pseudophakic monovision has been widely used in myopia patients with bilateral monofocal intraocular lens implantation. However, the crossed monovision, which is to correct the dominant eye for near vision and the non-dominant eye for distant vision, has been mentioned preferable for high myopic cataract patients by some studies. We have conducted this
study to compare clinical results to assess the feasibility of conventional and crossed monovision for high myopic pseudophakic patients by comparing patient satisfaction, visual function and spectacle independence.
METHODS: Forty-sixth high myopia patients were divided into two groups: 22 in crossed monovision group with patients whose refraction targeted to - 2.00 diopters (D) in the dominant eye and - 0.50D in the non-dominant eye; 24 in conventional monovision group with patients whose refraction targeted to - 0.50D in the dominant eye and - 2.00D in the non-dominant eye. Binocular uncorrected distance visual acuity (BUDVA), binocular uncorrected near visual acuity (BUNVA), binocular corrected distant visual acuity (BCDVA), binocular corrected near visual acuity (BCNVA), contrast visual acuity and stereoacuity were examined at postoperative 2 weeks, 1 month and 3 months. Questionnaires were completed by patients 3 months after binocular surgery to evaluate patients\' satisfaction and spectacle independence.
RESULTS: The conventional monovision and the crossed monovision group showed no significant differences of mean BUDVA, BUNVA, BCDVA, BCNVA 2 weeks, 1 month or 3 months postoperatively (P > 0.05). There was no difference in the bilateral contrast sensitivity or stereoscopic function between the convention conventional and crossed monovision groups (P > 0.05). Patient satisfaction with near and distant vision, as well as spectacle dependence did not differ significantly between the two groups (P > 0.05).
CONCLUSIONS: Crossed pseudophakic monovision exhibited similar visual function when compared with conventional monovision technique, which indicates that it is an effective option to improve the visual functionality and quality of life for high myopic patients who considering bilateral cataract surgery.
