Saving of Time Using a Software-Based versus a Manual Workflow for Toric Intraocular Lens Calculation and Implantation

Journal of Clinical Medicine, 2022
Background: To determine whether there is a significant saving of time when using a digital cataract workflow for digital data transfer compared to a manual approach of biometry assessment, data export, intraocular lens calculation, and surgery time ...

Repeatability of keratometry depending on tear film osmolarity

Acta Ophthalmologica, Volume 104, Issue 5, Page e530-e537, August 2026.
Abstract Purpose To determine the repeatability of keratometry and astigmatism measurements of patients depending on the tear film osmolarity using three different devices. Methods In this study, 97 eyes of 97 patients with a mean age of 64.92 ± 12.07 years received three repeated measurements with the IOLMaster 700 (Carl Zeiss Meditec, Jena, Germany),

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.

Prospective evaluation of a plate haptic toric intraocular lens [PDF]

Eye, 2001
Standard intraocular lenses (IOL) only correct the spherical component of aphakic refractive error. This study describes clinical experience with a foldable, injectable, toric IOL.Keratometric, refractive and visual data were collected on patients listed for cataract surgery.

One-year long-term clinical outcomes following diffractive trifocal toric intraocular lens implantation: retrospective observational case series study

Annals of Translational Medicine, 2022
Background Trifocal intraocular lens (IOL) provides three foci for the external light to the eye. The reduction of corneal astigmatism makes three foci to clearly focus on the fovea.

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 ...
