目的比较白内障手术中植入两种不同附加度数的多焦点人工晶状体(MIOL)术后的视觉质量.方法分析白内障行超声乳化吸出联合多焦点人工晶状体植入25例(30眼).随机分为两组:植入+2.5D组13例(16眼),植入+3.0 D组12例(14眼).分析患者的一般情况,观察两组术后3个月的裸眼视力及远、中、近距离的最佳矫正视力;绘制双焦曲线,并收集白内障术后患者问卷调查.结果术后3个月,两组裸眼及最佳矫正远视力和近视力差异均无统计学意义(P＞0.05),+2.5 D组全程中距离视力明显好于+3.0D组(P＜0.05),而近距离裸眼以及最佳矫正近视力则+3.0D组好于+2.5 D组.两组的双焦曲线,均能形成双峰,+2.5 D组的峰值在0.0D和2D.而+3.0D组的峰值在0.0D和2.5D上.+2.5D组在0.5D～2.0 D之间形成一个较高视力平台期.问卷调查显示:两组患者视远、视近的满意度均较高;而视中距离时,+2.5D组患者满意度明显高于+3.0 D组者并且脱镜率明显高于对照组(P＜0.05).两组患者术后无明显夜视力下降、眩光或光晕等干扰现象症状,其发生率,差异无统计学意义(P＞0.05).结论两种非球面MIOL植入术后,均提供了良好远距离视力,植入+ 2.5 D MIOL的全程中距离视力明显好于植入+3.0 D MIOL者,而植入+ 3.0 D MIOL则在33 cm处裸眼及最佳矫正视力表现较好.

Objective To compare the visual quality of implanting two kinds of multifocal intraocular lens (MIOL) with different near add.Methods This prospective, comparative, nonrandomized singleblind observational study comprised of 30 eyes of 25 patients that underwent phacoemulsification and implantation of multifocal IOL: SN6AD2 (13 cases, 16 eyes) (+ 2.5 D group) and SN6AD1 (12 cases, 14eyes) (+ 3.0 D group).Three months after the surgery, the uncorrected visual acuity and monocular near (33 cm and 40 cm), intermediate (50 cm, 60 cm, and 70 cm), and far distance (5 m) best corrected visual acuity were evaluated.Double focal curves were measured, and questionnaires of patients after phacoemulsification were collected.All of the parameters were evaluated at the 4-6mm pupil sizes.Results There was no statistically significant differences at far and near distance visual acuity were found between the two groups(P ＞ 0.05).The + 2.5 D group obtained better performances at all intermediate distances (50 cm, 60 cm and 70 cm;P ＜ 0.05).Whereas the near visual acuity was better in the + 3.0 D group (33cm;P ＜ 0.05).Both the two groups had double summit in the double focus curve.The summit of + 2.5 D group was at 0.0 D ～ 2 D.The summit of + 3.0 D group was at 0.0 D ～ 2.5 D.There was a high visual acuity level at 0.5 D ～ 2.0 D in + 2.5 D group.The questionnaire showed that it was satisfactory in near and far distance vision in both the two groups.But + 2.5 D group had better result in vision than + 3.0 D group in middle range vision (P ＜0.05).No interference such as dark vision dropping, flare or halo was observed.Conclusion Both of the two IOL models showed good results in distance vision.The + 2.5 D MIOL seems to provide better intermediate vision than the + 3.0 D MIOL.For near vision(33cm), the + 3.0 D MIOL performs better result than the + 2.5 D MIOL.
