Abstract
The assessment of patient satisfaction following cataract surgery is heavily reliant on the evaluation of visual quality, specifically after the placement of diffractive multifocal intraocular lenses (MIOLs) under varying pupil conditions. The objective of this study was to examine the visual and optical clarity following cataract phacoemulsification and the use of Tecnis ZMB00 MIOL for implantation. The study involved 116 individuals (135 eyes) who received cataract phacoemulsification and underwent Tecnis ZMB00 MIOL implantation. Assessments were conducted 1 week and 3 months after the surgery. These assessments involved measuring uncorrected and corrected visual acuity for distant, intermediate, and near vision. Additionally, scatter light values and wavefront aberrations were measured under different aperture settings of 3 and 5 mm. There was no noticeable disparity in visual acuity between 1 week and 3 months after the surgery. After 3 months of surgery, there was a considerable decrease in scatter light values and spherical aberrations compared to the values observed 1 week after surgery, under the setting of a 5 mm aperture. Moreover, the modulation transfer function values showed a significant rise after 3 months following the surgery, particularly under the 5 mm aperture condition. The most substantial increase was observed at the intermediate spatial frequency of 20 cycles per degree (cpd), in comparison to the values obtained 1 week after the operation. The combination of cataract phacoemulsification and Tecnis ZMB00 MIOL implantation yielded favorable visual acuity at various distances for patients. Furthermore, enhancements in the measurements of scattered light, higher-order aberrations, and modulation transfer function values were noted 3 months after the surgical procedure, specifically under the condition of a 5 mm pupil. These findings suggest an increase in visual clarity and night vision to a certain degree.
