Cataract surgery and intraocular lenses
A network meta-analysis of 15 studies and 1,178 eyes shorter than 22 mm placed Kane, Haigis and Olsen Standalone among the most accurate formulas. A statistically definitive single winner has not emerged.
doi: 10.1097/j.jcrs.0000000000001793A meta-analysis found the strongest associations between late IOL dislocation and zonular weakness, trauma, uveitis and pseudoexfoliation. A factor's frequency among cases does not necessarily establish independent risk.
doi: 10.1097/j.jcrs.0000000000002025A network meta-analysis of 9 studies and 399 eyes compared 7 formulas for flanged intrascleral IOL fixation. Barrett Universal II ranked consistently well, but no formula showed statistically significant superiority.
doi: 10.1007/s00417-026-07462-3A network meta-analysis of 7 studies and 1,060 eyes compared 12 IOL formulas after vitrectomy with silicone oil tamponade. Kane ranked first within ±0.50 D, while EVO led within ±1.00 D.
doi: 10.1159/000551331An overview of 85 publications mapped indications for toric IOLs, preoperative measurement, calculation, surgical technique, rotational stability and unresolved questions in astigmatism correction during cataract surgery.
doi: 10.1016/j.ajo.2026.02.043The study compared eight modern IOL power formulas in cataract patients with extremely long eyes.
doi: 10.1016/j.ajo.2026.05.026A randomised trial compared emmetropia, mini-monovision, monovision and partial-range-of-field extended IOLs.
doi: 10.1111/aos.70145A randomised trial tested whether intracameral air could reduce endothelial cell loss after surgery for dense nuclear cataract.
doi: 10.1111/ceo.70161A multicentre randomised trial compared three toric IOLs after phacoemulsification in eyes with regular corneal astigmatism.
doi: 10.1097/j.jcrs.0000000000002023An overview of eight systematic reviews compared multifocal, trifocal, EDOF, accommodative and monofocal IOLs.
