Background: Visual acuity (VA) outcomes after phacoemulsification cataract surgery in the very elderly (≥90 years) compared to those in younger patients remain unclear till date.
Methods: We retrospectively investigated 138 (group 1) and 152 (group 2) eyes in patients aged ≥90 and < 80 years, respectively, with senile cataracts who underwent phacoemulsification and intraocular lens implantation between 2014 and 2016. Four highly experienced ophthalmic surgeons performed the procedures.
