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

Acta 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 ...

Analysis of best corrected visual acuity following corneal refractive surgery comparing low and standard predicted postoperative keratometry [PDF]

, 2018
BACKGROUND: It is a commonly held view in the ophthalmologic community that eyes with sufficiently low calculated postoperative corneal keratometry, less than 35 diopters, should not undergo corrective refractive laser surgery (CRLS) due to the increased

Progression and topographic subtypes of Terrien marginal degeneration

Acta Ophthalmologica, Volume 104, Issue 1, Page 33-43, February 2026.
Abstract Purpose To report long‐term outcomes and to search for immunological and genetic risk factors in Terrien marginal degeneration (TMD). Methods Retrospective, in part prospective, hospital‐based longitudinal follow‐up study of 32 eyes of 16 Finnish patients from 2012 to 2023. Median follow‐up was 7.3 years (range, 0.3–15.2).

Tolerance to surgically induced anisometropia—A systematic review

Acta Ophthalmologica, Volume 104, Issue 1, Page 10-21, February 2026.
Abstract Surgically induced anisometropia is well tolerated by some individuals, while others experience binocular visual complaints. Surgically induced anisometropia is a common treatment for presbyopia and may also intentionally or non‐intentionally be the results after surgery for unilateral cataract with ametropia in the fellow eye.
