The aim of the study was evaluation and comparison of clinical results of two types of rotationally asymmetric multifocal intraocular lens (LENTIS Mplus and LENTIS MplusX).
The study included 247 eyes of 124 patients aged 25 - 76 years (mean, 58 years). After phacoemulsification multifocal intraocular lens LENTIS Mplus (group A, n = 141) or LENTIS MplusX (group B, n = 106) was implanted. Patients were divided into two groups according to the type of intraocular lens. Patients were evaluated at 1 month, 3 months and 6 months after surgery. We assessed the uncorrected visual acuity, best corrected visual acuity, subjective refraction, contrast sensitivity and subjective satisfaction.
Mean preoperative monocular uncorrected distance visual acuity (UCDVA) in the group A was 0,40 ± 0,27; in the group B 0,34 ± 0,25. Postoperatively UCDVA was statistically significant improved in both groups (group A: 1,01 ± 0,20; group B: 0,90 ± 0,15). Mean preoperative monocular uncorrected near visual acuity (UCNVA) was Jaeger (J) 12,82 ± 4,16 (group A), resp. J 12,73 ± 3,99 (group B). Postoperatively UCNVA was statistically significant improved in both groups (group A: J 1,81 ± 1,42; group B: J 1,54 ± 1,72). There was not found statistically significant difference between both groups in these parameters. Contrast sensitivity was evaluated in patients who have undergone clear lens extraction in both eyes. There was not found the statistically significant reduction of contrast sensitivity in both groups. Subjective satisfaction was assessed in the range of marks 1-5. The average mark of the subjective satisfaction ratings in the group A was 1,37; in the group B 1,25.
Our study found the multifocal intraocular lens LENTIS Mplus and LENTIS MplusX give high-quality distance and near vision and provide high degree of spectacle independence. There was not found statistically significant difference in all parameters between the Group A (implantation Mplus LENTIS) and the Group B (implantation LENTIS MplusX) in our study. However, in our study we have observed higher subjective satisfaction and lower incidence of optical phenomena in the Group of patients with the implantation of intraocular lens LENTIS MplusX.Key words: LENTIS Mplus, LENTIS MplusX, visual acuity, contrast sensitivity, optical phenomen.
本研究旨在评估和比较两种旋转不对称多焦点人工晶状体（LENTIS Mplus和LENTIS MplusX）的临床效果。
本研究纳入了124例年龄在25 - 76岁（平均58岁）患者的247只眼。在白内障超声乳化术后，植入多焦点人工晶状体LENTIS Mplus（A组，n = 141）或LENTIS MplusX（B组，n = 106）。根据人工晶状体类型将患者分为两组。在术后1个月、3个月和6个月对患者进行评估。我们评估了未矫正视力、最佳矫正视力、主观验光、对比敏感度和主观满意度。
A组术前平均单眼未矫正远视力（UCDVA）为0.40±0.27；B组为0.34±0.25。术后两组UCDVA均有统计学意义的改善（A组：1.01±0.20；B组：0.90±0.15）。A组术前平均单眼未矫正近视力（UCNVA）为Jaeger（J）12.82±4.16，B组为J 12.73±3.99。术后两组UCNVA均有统计学意义的改善（A组：J 1.81±1.42；B组：J 1.54±1.72）。两组在这些参数上未发现统计学显著差异。对双眼均行透明晶状体摘除术的患者进行了对比敏感度评估。两组均未发现对比敏感度有统计学显著降低。主观满意度采用1 - 5分进行评估。A组主观满意度评分的平均分为1.37；B组为1.25。
我们的研究发现，多焦点人工晶状体LENTIS Mplus和LENTIS MplusX可提供高质量的远视力和近视力，并提供高度的脱镜率。在我们的研究中，A组（植入LENTIS Mplus）和B组（植入LENTIS MplusX）在所有参数上均未发现统计学显著差异。然而，在我们的研究中，我们观察到植入LENTIS MplusX人工晶状体的患者组主观满意度更高，光学现象发生率更低。关键词：LENTIS Mplus，LENTIS MplusX，视力，对比敏感度，光学现象
