Intraindividual comparative study of corneal and ocular wavefront aberrations after biaxial microincision versus coaxial small-incision cataract surgery

Aim: To compare the optical outcomes of biaxial microincision cataract surgery (B-MICS) versus coaxial small-incision cataract surgery (C-SICS).Methods: Thirty patients (sixty eyes) with bilateral age-related cataract underwent B-MICS through a 1.7 mm clear corneal incision (CCI) in one eye and C-SICS through a 2.8-mm CCI in the other eye. Every eye was implanted with a micro-incision aspheric aberration-free intraocular lens (Akreos MI60 AO). Preoperative corneal aberrations, and 3-month postoperative corneal and total ocular aberrations were calculated and compared.Results: The 3-month postoperative corneal root mean square (RMS) of third- to sixth-order aberrations (p
