In this presentation “A comparative study on visual and optical performance of Akreos AO and Kontur AB IOLs, after phacoemulsification cataract surgery”, Gharaee H et al have evaluated the visual performances by comparing two aspheric intraocular lenses (IOL). They indicate that with age positive spherical aberration increases, and consequently mesopic contrast sensitivity decreases and in such condition application of spheric IOL would aggravate the positive spherical aberration and mesopic contrast sensitivity.1 In this randomized, comparative, interventional investigation 35 aged patients (mean-age ¼ 60.97 ± 7.00 years) have been selected. Randomly, in one eye Akreos AO and in the second eye Kontur AB IOLs has been placed, following phacoemulsification. They indicate that although the visual acuity and photopic, mesopic contrast sensitivity, and aberrometric factors were not significantly different between two lenses but aberrometric and contrast sensitivity were somehow more in favor for Akreos AO.
