The authors of this study evaluated the potential benefit on visual performance of a novel 3 week visual rehabilitation program based on the use of Gabor patches in patients undergoing bilateral cataract surgery with the implantation of two models of trifocal diffractive intraocular lens (IOL). A total of 30 patients were randomly assigned to two groups: a study group (15 patients) that used a videogame based on Gabor patches and a placebo group (15 patients) that used a videogame without specific stimuli for improving visual performance. No statistically significant differences between groups were found in distance, intermediate, and near post-training visual acuity ( ≥ 0.15). Significantly better distance contrast sensitivity (CS) was found for the spatial frequencies of 6 ( = 0.02) and 12 cpd ( = 0.01) in the study group. Likewise, significantly better values of near CS were found in the study group compared to the placebo group for the spatial frequency of 1.5 cpd ( = 0.02). In conclusion, a 3 week visual rehabilitation program based on the use of Gabor patches in the immediate postoperative period after the bilateral implantation of trifocal diffractive IOLs seems to be beneficial for improving both distance and near visual performance achieved with the implant.
本研究的作者评估了一项为期3周的新型视觉康复计划对视觉表现的潜在益处，该计划基于对接受双侧白内障手术并植入两种三焦点衍射人工晶状体（IOL）模型的患者使用Gabor斑块。总共30名患者被随机分为两组：一组是研究组（15名患者），使用基于Gabor斑块的电子游戏；另一组是安慰剂组（15名患者），使用没有特定改善视觉表现刺激的电子游戏。训练后，两组在远、中、近视力（≥0.15）方面未发现统计学上的显著差异。研究组在空间频率为6（P = 0.02）和12 cpd（P = 0.01）时，远视力对比敏感度（CS）显著更好。同样，研究组在空间频率为1.5 cpd时，近CS值与安慰剂组相比显著更好（P = 0.02）。总之，在双侧植入三焦点衍射IOL后的术后早期，基于使用Gabor斑块的3周视觉康复计划似乎有利于改善植入后获得的远视力和近视力表现。
