Abstract | INTRODUCTION: MATERIAL AND METHODS: A total of 30 patients already scheduled for cataract surgery were enrolled and microperimetry and visual acuity evaluation was performed before and after cataract extraction. The patients were allocated to 1 of 3 study groups in accordance with the main cataract subtype: nuclear, cortical, or posterior subcapsular (PSC) cataract. RESULTS: Visual acuity increased significantly after cataract surgery (from 0.34 to 0.00 logMar, p < 0.001, paired t test). Similarly, median retinal sensitivity increased significantly from 23 dB (IQR 21-25 dB) to 27 dB (IQR 25.75-28 dB) (p < 0.001, Wilcoxon test). The increase of retinal sensitivity after cataract surgery was highest in the PSC cataract group. CONCLUSION: This study showed an increase in retinal sensitivity values after cataract removal, especially in the PSC group. Therefore, coexisting cataract should be considered when interpreting microperimetry results.
