摘要

目的 

评估三焦点人工晶体植入术后的视力及屈光结果。

设计 

具有前瞻性的,非随机非比较性案例。

方法 

观察对象:27名患者54只眼,双眼植入蔡司三焦点人工晶体(AT LISA tri839 MP)并预先登记,选取标准为未接受过除白内障及屈光性晶体手术以外的眼科手术,没有角膜不规则散光〉1.5D,且没有其他角膜及眼部病理性异常。

干预及观察方式:术后1个月及3个月检查,包括综合验光、单眼及双眼分别在4m,80cm 及40cm的未矫正远中近视力及最佳远视力下的中近视力、裂隙灯、OCT。术后3个月进行双眼离焦测试、及明暗光线下对比敏感度测试以及术后有关眼镜依赖及视觉质量的主观问卷。

主要观察结果:术后三个月单眼、双眼未矫正及最佳远距离视力下4m, 80cm,40cm(logMAR)各距离视力,离焦曲线,对比敏感度及视觉质量主观问卷结果。

结果

术后三个月SE为0.05 ± 0.32 D,双眼未矫正的远中近分别为0.1 ± 0.1 logMAR, 0.0 ± 0.1 logMAR and 0.0 ± 0.1 logMAR。排除一些视觉干扰的因素,92%的患者声称如果可以再次选择,他们仍然会选择蔡司三焦点。

结论

评估显示术后三个月,三焦点植入后远中近视力均达到0.1logMAR或者更好,高患者术后满意度,高脱镜率,仅部分患者会存在一些视觉干扰。

Abstract

Purpose

To evaluate visual and refractive outcomes after implantation of a trifocal intraocular lens (IOL).

Design 

Prospective, nonrandomized non-comparative case series.

Methods 

Patient or Study Population: 27 patients (54 eyes) who had bilateral implantation of the AT LISA trifocal IOL (AT LISA tri839MP, ZEISS) pre-enrollment. Exclusion criteria were previous ocular surgeries excluding cataract surgery and refractive lens exchange, irregular corneal astigmatism of > 1.5 D and ocular pathologies or corneal abnormalities.

Intervention or Observation Procedure(s): Postoperative examination at 1 and 3 months included manifest refraction, monocular and binocular uncorrected (UDVA) and distance corrected (CDVA) visual acuity in 4m, 80cm and 40cm, slit lamp examination and tomography. At 3 months defocus testing, binocular contrast sensitivity (CS) under photopic and mesopic conditions and a questionnaire on subjective quality of vision, optical phenomena and spectacle independence were performed.

Main Outcome Measure(s): 3 months postoperative monocular and binocular UCVA and DCVA in 4m, 80cm and 40cm (LogMAR), defocus curve, CS and quality of vision questionnaire results

Results Mean spherical equivalent was 0.05 ± 0.32 D 3 months postoperative. Binocular UDVA at distance, intermediate and near was -0.1 ± 0.1 logMAR, 0.0 ± 0.1 logMAR and 0.0 ± 0.1 logMAR, respectively. Despite some optical phenomena, 92% of patients would choose the same IOL again.

Conclusion Evaluation of a trifocal IOL showed good VA (0.1 logMAR or better) at far, intermediate, and near distance; high patient satisfaction despite some optical phenomena; and high spectacle independence 3 months postoperatively.
