目的:通过超声乳化白内障吸除联合双眼分别植入折射型多焦点人工晶状体(Rezoom NXG1 MIOL)与衍射型多焦点人工晶状体(ReSTOR SA60D3 MIOL),评价个性化搭配模式的术后视觉质量。
方法:将拟行超声乳化白内障吸除术的年龄相关性白内障患者分为多焦点人工晶状体(MIOL)组与单焦点人工晶状体(SIOL)组,每组各10例。MIOL组为主视眼植入ReZoom NXGl MIOL,对侧眼植入ReSTOR SA60D3 MIOL; SIOL组为双眼植入Sensar AR40e IOL。术后1mo,观察两组患者远、中、近视力,对比敏感度,焦点深度及问卷调查,并对结果进行分析。
结果:术后1mo,MIOL组患者获得满意的远视力,且中、近视力明显优于SIOL组。比较不同空间频率对比敏感度,除了暗光条件下,在3c/d空间频率SIOL组要优于MIOL组外,其余各空间频率两组无明显差别,而在明光条件下5种空间频率均未见明显差别。MIOL组的焦点深度可达5.30D,显著高于SIOL组的2.85D。MIOL组的中、近距离的视觉质量满意度也较SIOL组有明显的提高。
结论:个性化搭配IOL能在一定范围内给白内障术后患者提供更好的全程视力,提高白内障患者术后视觉质量。

AIM: To investigate the visual quality after phacoemulsification combined with customized implantation of refractive multifocal intraocular lens(Rezoom NXG1 MIOL)and diffractive multifocal intraocular lens(ReSTOR SA60D3 MIOL).
METHODS: A prospective, nonrandomized, unmasked clinical trial was performed. Patients with age-related cataract who were to undergo phacoemulsification were divided into two groups: multifocal intraocular lens(MIOL)vs monofocal intraocular lens(SIOL). 10 patients were included in each group. In the group of MIOL, patients got implantation of ReZoom NXGl MIOL in the dominant eye and ReSTOR SA60D3 MIOL in the fellow eye while patients in the group of SIOL got implantation of Sensar AR40e IOL bilaterally. One month postoperatively, distance, mid-range and near visual acuity, contrast sensitivity, focal depth were measured. Satisfaction of visual quality was investigated by questionnaire.
RESULTS: One month postoperatively, the patients in the MIOL group were satisfied with distance visual acuity, meanwhile they achieved better mid-range and near visual acuity compared with patients in the SIOL group. Under mesopia condition, SIOL implantation gave better contrast sensitivity in spatial frequency at 3 cpd, and no difference was observed in other spatial frequency, while under photopia condition, no significant difference was observed among all the five types of spatial frequency. The focal depth of MIOL was 5.30D, which was significantly higher than 2.85D of the SIOL. Satisfaction of visual quality of near and mid-range was significantly higher in the MIOL group.
CONCLUSION: Customized implantation of intraocular lens after phacoemulsification provides better visual acuity and visual quality postoperatively.
