A comparative study on visual and optical performance of Akreos AO and Kontur AB IOLs after phacoemulsification cataract surgery

Purpose: akreos ao and kontur ab are two commonly used intraocular lenses (iols) in iran. this study was designed to evaluate the visual performance of these lenses. methods: in a comparative interventional study,35 patients (70 eyes) were recruited,and each iol was implanted in one eye of the patients,randomly. best corrected visual acuity (bcva),contrast sensitivity,aberrometric analysis,and depth of focus were evaluated 1 month and 3 months postoperatively. a visual quality questionnaire was also filled for each eye,and the results were compared. results: mean age of the patients was 60.97 ± 7.00 years. bcva was not significantly different between the two eyes,before,1 month,and 3 months postoperatively (p > 0.05 for all). photopic and mesopic contrast sensitivity was not different between the two lenses instead of photopic 18 cycles per degree,3 months postoperatively and in mesopic 6 cycles per degree 1 month postoperatively (p = 0.034 and p = 0.002,respectively). aberrometric factors including horms,total rms,and higher order without z(4,0) were not significantly different between the two lenses (p > 0.05 for all),but they were slightly lower for akreos ao. post-operative distance-corrected visual acuity for intermediate and near vision were not different between the two groups (p > 0.05,respectively). conclusion: visual performance of akreos ao and kontur ab is similar. however,contrast sensitivity and aberrometric parameters are slightly better for akreos ao iol. © 2016 iranian society of ophthalmology.
