Cataract surgery and intraocular lenses
In a randomized study of 56 eyes, sulcus placement with optic capture after a capsular tension ring produced a more myopic result than standard in-the-bag implantation.
doi: 10.1016/j.pdpdt.2026.105539An analysis of 1,314 eyes found that total keratometry changed predictions according to the posterior-to-anterior corneal radius ratio, without a uniform gain in accuracy.
doi: 10.1016/j.ajo.2026.08.020In a retrospective series of 169 eyes, a formula combining the original IOL, biometry and manifest refraction predicted lens-exchange outcomes more accurately than Barrett Rx.
doi: 10.1016/j.ophtha.2026.01.017In a randomized masked study, 40 patients received DEN00V in one eye and AN6V in the fellow eye. Both provided extended vision at three months, while the primary endpoint favored AN6V.
doi: 10.1016/j.ajo.2026.04.014A systematic review of 19 reports and 1,564 eyes assessed residual cylinder, rotation and reoperation after at least one year. Correction generally persisted to two years, but longer evidence was sparse.
doi: 10.1097/j.jcrs.0000000000001917A prospective study of 28 patients evaluated bilateral Liberty 677MTY implantation. Most participants reported spectacle independence at one year, but the study had no control group.
doi: 10.1186/s12886-026-05145-5In 92 patients, three EDOF approaches improved uncorrected intermediate and near vision compared with a monofocal lens, while the profile of photic phenomena differed between designs.
doi: 10.1016/j.jfo.2026.104823A randomized study of 70 cataract patients compared PanOptix with Vivity. Stereopsis favored the EDOF group at one month, while contrast sensitivity did not differ significantly between groups.
doi: 10.4103/IJO.IJO_2015_25In 67 patients, an EDOF lens in the dominant eye and PanOptix in the nondominant eye provided good binocular vision across distances, but overall satisfaction fell to 38.5% by 12 months.
doi: 10.3341/kjo.2026.0105A meta-analysis of 28 studies found lower mean absolute error with Hill-RBF 3.0 than with Haigis, Holladay 1 and SRK/T. Performance was more often comparable against newer formulas.
