Comparison of visual performance with an aspheric intraocular lens and a spherical intraocular lens

摘要: Purpose To compare the visual performance after implantation of Akreos Adapt Advanced Optics aspheric intraocular lens (IOL) and Sensar AR40e spherical acrylic IOL. Setting Eye Department, Southampton University Hospital, United Kingdom. Design Randomized masked single-center clinical trial. Methods Patients with bilateral cataract who were older than 50 years a biometry-predicted IOL power between 10.0 diopters (D) 30.0 D recruited. Outcome measures included corrected distance acuity (CDVA) using high-contrast logMAR chart, contrast sensitivity measured Pelli-Robson range accommodation Royal Air Force (RAF) rule, pseudoaccommodation mesopic scotopic pupil diameters refractor, patient satisfaction evaluated previously validated questionnaire 3 months second-eye surgery. Results The difference in mean value 2 IOLs (40 patients) was 0.015 (95% confidence interval [CI], 0.0009 to 0.070) for CDVA favor IOL, 0.02 CI, −0.0534 0.0159) sensitivity, 0.05 −1.90 +2.90) accommodation. Questionnaire results showed no dysphotopsia or IOLs. Conclusions Although there statistically significant differences accommodation, dysphotopsia, subjective preference IOLs, significant, but not clinically important (relative 1.5%), Financial Disclosure No author has financial proprietary interest any material method mentioned.
