简要总结
This is a prospective comparative interventional clinical study, that took place from January 2021 to November 2021. Twenty patients (20) were enrolled in this study 10 patients in each group. It was designed for comparison of uncorrected and best corrected distance and intermediate vision in patients whom implanted with monofocal Tecnis Eyhance or Tecnis 1-piece IOLs.
详细描述
Purpose To determine the Uncorrected and best-corrected distance, and intermediate visual acuity in a new innovative monofocal intraocular lens compared with standard monofocal lens.
Methods This is a prospective comparative interventional clinical study, that took place from January 2021 to November 2021. 40 eyes of Twenty patients (20) were enrolled in this study, patients who are candidates for cataract extraction by phacoemulsification were included in this study and underwent thorough preoperative examination and post-operative evaluation at 3 months after the 2nd eye operation, of distance, intermediate, near add, contrast sensitivity and incidence of photic phenomena using a printed questionnaire for evaluating this incidence and binocular defocus curves were analyzed.

结局指标
主要结局
Uncorrected and best-corrected distance, and intermediate visual acuity.
时间窗: 3 months post operative
Distance visual acuities were examined by ETDRS chart and intermediate and near visual acuity by Jaeger chart at 66 cm and 33 cm respectively.Measured values of the visual acuity were expressed in decimal values and converted to logMAR values.
次要结局
- Contrast sensitivity(3 months post operative)
