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

open access: yesActa Ophthalmologica, Volume 104, Issue 2, Page 181-192, March 2026.
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, Volume 104, Issue 2, Page e173-e182, March 2026.
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.

Nationwide trends in macular hole, epiretinal membrane and floaters surgery, 2010–2023

open access: yesActa Ophthalmologica, Volume 104, Issue 2, Page 193-200, March 2026.
Abstract Purpose To examine the incidence of pars plana vitrectomy (PPV) for full‐thickness macular hole (FTMH), epiretinal membrane (ERM) and floaters over time and across regions in Denmark. Methods This nationwide registry‐based study included all patients undergoing PPV for FTMH, ERM, or floaters in Denmark from 2010 to 2023.

Technological characteristics of cataract surgery in eyes with posterior chamber phakic intraocular lens implanted previously

open access: yesJournal of Ophthalmology, 2016
Introduction. Implantation of phakic intraocular lenses (PIOL) is used for the correction of high myopia. The problem of PIOL implantation is that cataract may develop in a long-term period after surgery due to the contact of constructive PIOL elements ...
