Abstract

OBJECTIVE

To compare the visual outcomes and subjective parameters in patients who underwent implantation of ReSTOR apodized diffractive multifocal intraocular lens on bilateral eyes with those in patients who had monofocal intraocular lens in cataract surgery.

METHODS

Retrospective observational case series. 50 eyes of 25 patients received ReSTOR multifocal intraocular lens (multifocal group) and 56 eyes of 28 patients taken implantation of Natural monofocal intraocular lens (monofocal group) participated in the study. The distance and near visual acuity were compared, as well as contrast and glare sensitivity. Visual symptom and spectacle dependence were assessed using a standardized questionnaire. The minimal follow-up was 3 months.

RESULTS

An uncorrected distance visual acuity of 0.6 or better was achieved in 94% of eyes in multifocal group and 96% in the monofocal group, respectively (chi(2) = 0.347, P > 0.05). Uncorrected near visual acuity was J(3) or better in 88% of eyes in the multifocal group and 13% in the monofocal group (chi(2) = 60.315, P < 0.01). Best distant corrected near visual acuity was Jr3 or better in 90% of eyes in the multifocal group and 11% in the monofocal group (chi(2) = 66.515, P < 0.01). No significant difference in contrast and glare sensitivity was found between the groups (P > 0.05). Glare was reported as severe in 12% of the multifocal group and 7% of the monofocal group, respectively (chi(2) = 0.365, P > 0.05). Halo was reported as severe in 8% of the multifocal group and 4% of the monofocal group, respectively (chi(2) = 0.485, P > 0.05). 96% of patients in both groups never had to wear glasses for the distant purpose (chi(2) = 0.007, P > 0.05), and 80% in multifocal group and 11% in monofocal group never had to wear glasses for the near purpose (chi(2) = 25.811, P < 0.01).

CONCLUSION

The ReSTOR apodized diffractive intraocular lens provided predictably excellent uncorrected distance and near visual acuities, and obtained satisfactory quality of vision. Spectacle independence was significantly higher with this multifocal intraocular lens.

摘要

目的

比较白内障手术中双眼植入ReSTOR变迹衍射多焦点人工晶状体患者与植入单焦点人工晶状体患者的视觉效果和主观参数。

方法

回顾性观察病例系列。25例患者的50只眼接受了ReSTOR多焦点人工晶状体（多焦点组），28例患者的56只眼植入了自然单焦点人工晶状体（单焦点组）参与研究。比较了远视力和近视力，以及对比敏感度和眩光敏感度。使用标准化问卷评估视觉症状和对眼镜的依赖程度。最短随访时间为3个月。

结果

多焦点组94%的眼和单焦点组96%的眼未矫正远视力达到0.6或更好（χ² = 0.347，P > 0.05）。多焦点组88%的眼和单焦点组13%的眼未矫正近视力达到J(3)或更好（χ² = 60.315，P < 0.01）。多焦点组90%的眼和单焦点组11%的眼最佳矫正远视力下的近视力达到Jr3或更好（χ² = 66.515，P < 0.01）。两组之间在对比敏感度和眩光敏感度方面未发现显著差异（P > 0.05）。多焦点组12%的患者和单焦点组7%的患者报告眩光严重（χ² = 0.365，P > 0.05）。多焦点组8%的患者和单焦点组4%的患者报告光晕严重（χ² = 0.485，P > 0.05）。两组中96%的患者远距离视物无需戴眼镜（χ² = 0.007，P > 0.05），多焦点组80%的患者和单焦点组11%的患者近距离视物无需戴眼镜（χ² = 25.811，P < 0.01）。
