摘要
目的比较三焦点人工晶状体(IOL)与双焦点IOL植入术后早期视力情况、视觉质量及患者满意度。方法 62例(75眼)行白内障超声乳化吸除联合IOL植入术的白内障患者,根据治疗方法不同分为三焦点IOL组(采用三焦点IOL植入术, 20例25眼)和双焦点IOL组(采用双焦点IOL植入术, 42例, 50眼)。术后随访3个月,测量两组患者远、中、近视力(LogMAR),离焦曲线,调查问卷患者满意度,并进行组间比较。结果三焦点IOL组远、中、近视力分别为(0.04±0.05)、(0.10±0.08)、(0.07±0.08),双焦点IOL组远、中、近视力分别为(0.06±0.06)、(0.36±0.12)、(0.09±0.07),两组患者远、近视力比较差异无统计学意义(t=-1.43、-1.11, P>0.05);三焦点IOL组患者中视力优于双焦点IOL组,差异具有统计学意义(t=-9.78, P<0.05)。两组离焦曲线在0 D处均存在最高峰,三焦点IOL组的离焦曲线中在-1.0~2.5 D平缓稳定于高位。通过问卷调查,三焦点IOL组和双焦点IOL组患者分别有2例和4例出现光晕,但不影响日常生活。三焦点IOL组满意度20%(5/25)明显高于双焦点IOL组的4%(2/50),差异具有统计学意义(P<0.05)。结论三焦点IOL与双焦点IOL植入术后均可获得较好的远近视力,三焦点IOL植入术后的中视力优于双焦点IOL植入,三焦点IOL植入术与双焦点IOL植入术视觉质量相当。
        Objective To compare the early visual acuity, visual quality and patient satisfaction between trifocal intraocular lens(IOL) and bifocal IOL implantation. Methods A total of 62 cataract patients(75 eyes) undergoing phacoemulsification combined with IOL implantation were divided by different treatment methods into trifocal IOL group(receiving trifocal IOL implantation, 20 cases, 25 eyes) and bifocal IOL group(receiving bifocal IOL implantation, 42 cases, 50 eyes). After 3 months of follow-up, the distant, middle and near vision(LogMAR), defocus curve and patient satisfaction of the questionnaire were measured and compared between the two groups. Results Trifocal IOL group had distant, middle and near vision respectively as(0.04±0.05),(0.10±0.08) and(0.07±0.08), which were(0.06±0.06),(0.36±0.12) and(0.09±0.07) in bifocal IOL group. Both groups had no statistically significant difference in distant and near vision(t=-1.43,-1.11, P>0.05). Trifocal IOL group had better middle vision than bifocal IOL group, and the difference was statistically significant(t=-9.78, P<0.05). The defocusing curves of the two groups had the highest peak at 0 D, and the defocusing curves of the three-focus IOL group were stable at high level of-1.0~2.5 D. Through questionnaires, 2 patients and 4 patients in the trifocal IOL group and the bifocal IOL group showed halo, but did not affect daily life. Trifocal IOL group had obviously higher satisfaction degree as 20%(5/25) than 4%(2/50) in bifocal IOL group, and the difference was statistically significant(P<0.05). Conclusion Trifocal IOL and bifocal IOL can obtain better distant and near vision after implantation. The intermediate vision of trifocal IOL is better than that of bifocal IOL implantation. The visual quality of trifocal IOL implantation is similar to that of bifocal IOL.
