Exploring patient involvement in target refraction decision‐making for cataract surgery

Optometry and Vision Science, Volume 103, Issue 5, May 2026.
ABSTRACT Purpose Post‐surgical emmetropia is frequently used as the target refraction in cataract surgery. Such target does not reflect guidance available from regulatory or professional bodies which recommend that the refractive implications of surgery, notably changes in post‐surgical spectacle needs, should be discussed with the patient.

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

Acta Ophthalmologica, Volume 104, Issue 2, Page e122-e138, March 2026.
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 ...
