A review of angle kappa and multifocal intraocular lenses and their effect on visual outcomes

open access: yesActa Ophthalmologica, EarlyView.
Abstract Although most patients are satisfied with their vision after multifocal intraocular lens (IOL) implantation, dissatisfaction has been reported for various reasons, including poor visual outcomes and visual disturbances. Many published reports hypothesise that preoperative angle kappa may be an associated factor in patient dissatisfaction ...

A two‐step formula constant optimization strategy for minimal standard deviation and zero mean prediction error in IOL power calculation

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To investigate the precision and accuracy performance of a two‐step approach for optimizing lens formula constants (FC) with a refractive offset correction (RO) as a second tuning parameter. Methods Using IOLMaster 700 biometric data from 4 datasets (886/613/821/467 eyes treated with the Hoya Vivinex/Johnson&Johnson ZCB00/Alcon SA60AT ...

Risk of rhegmatogenous retinal detachment following pars plana vitrectomy for full‐thickness macular hole and epiretinal membrane in pseudophakic eyes

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To estimate the risk of rhegmatogenous retinal detachment (RRD) following pars plana vitrectomy (PPV) for full‐thickness macular hole (FTMH) or epiretinal membrane (ERM) in pseudophakic eyes. Methods We conducted a nationwide Danish registry‐based cohort study from 2010 to 2023.
