【摘要】： 本研究通过比较双眼混合植入多焦点人工晶状体及双眼植入单焦点人工晶状体术后视功能及视觉质量的状态,评价混合植入多焦点人工晶状体术后临床效果及应用价值。研究对象选择在吉大二院眼科医院因双眼白内障行双眼超声乳化白内障吸出联合人工晶状体植入术的患者40例,其中10例根据患者需求混合搭配植入两种不同折射原理的多焦点人工晶状体,余30例双眼植入单焦点人工晶状体,观察术后12个月不同光照条件下的远、中、近距离的裸眼及矫正视力,立体视锐度,影像不等检查,双眼及单眼远距对比敏感度测定,焦点深度及离焦曲线的测定,阅读速度的检测及视觉质量问卷调查。通过随访,术后12个月多焦组患者裸眼全程视力表现优异,与单焦组矫正后视力相当。两组立体视及不等象方面,多焦组表现较好。多焦组远距对比敏感度比各单眼多焦点人工晶状体略高,但略低于单焦组患者,并无统计学意义。多焦组具有较宽泛的焦点深度,比各单眼多焦点人工晶状体焦点深度更宽。阅读速度的比较来看,多焦组裸眼阅读速度接近单焦组矫正阅读速度。术后满意度及脱镜率多焦组较高,不良视觉发生率方面多焦组略高,但对日常生活并无影响。本研究结果表明,混合植入多焦点人工晶状体设计的确能够在远、中、近全程视力上降低患者对眼镜的依赖,在安全可靠基础上实现患者视觉及生活质量的提高。
[Abstract]:In this study, we compared the visual function and visual quality between binocular mixed intraocular lens implantation and single focus intraocular lens implantation, and evaluated the clinical effect and application value of mixed implantation of multi-focus intraocular lens.Participants 40 patients with binocular phacoemulsification combined with intraocular lens implantation were selected from ophthalmological hospital of Jida second Hospital.According to the needs of the patients, 10 patients were mixed with two different refraction principles of multi-focus intraocular lens implantation, and the remaining 30 eyes were implanted with single focus intraocular lens. The distance and distance under different illumination conditions were observed 12 months after operation.Close eye and corrected visual acuity, stereopsis acuity, image inequality, distance contrast sensitivity of binocular and monocular, focal depth and defocus curve, reading speed and visual quality questionnaire.After 12 months follow-up, the uncorrected visual acuity of multi-focus group was superior to that of single-focus group.In both groups, multi-focal group performed well in stereo vision and unequal vision.The far contrast sensitivity of multi-focal group was slightly higher than that of single-eye multi-focus intraocular lens, but slightly lower than that of single focus group, and there was no statistical significance.The focal depth of multi-focal group is wider than that of single-eye multi-focal intraocular lens.In comparison of reading speed, the open eye reading speed of multi-focus group was close to that of single-focus group.The degree of satisfaction and the rate of devitoscopy were higher in the multi-focal group, but had no effect on the daily life in the multi-focal group.The results of this study indicate that the mixed implantation of multi-focus intraocular lens design can reduce the patients' dependence on eyeglasses and improve their visual and quality of life on the basis of safety and reliability.
