Correlative Comparison of Three Ocular Axes to Tilt and Decentration of Intraocular Lens and Their Effects on Visual Acuity

, 2020
To evaluate which ocular axis, the corneal topographic axis (CTA), pupillary axis (PA) or line of sight (LOS), for measuring the tilt and decentration of intraocular lens (IOL) is most relevant to correct distance visual acuity (CDVA).

Relationship between anterior capsule opening and direction of intraocular lens decentration

Journal of Cataract & Refractive Surgery, 2023
Purpose: To compare intraocular lens (IOL) decentration between patients in whom the continuous curvilinear capsulorhexis (CCC) completely covers the IOL optic and those in whom it incompletely covers the IOL optic and determine how an incompletely covered CCC affects the IOL position. Setting:

Congenital aniridia: European COST action ANIRIDIA‐NET guidelines for diagnosis, management and care

Acta Ophthalmologica, Volume 104, Issue 3, Page 267-279, May 2026.
Abstract Congenital aniridia is a rare ocular disorder affecting the majority of eye structures and can be associated with systemic manifestations. The main visible phenotypic characteristic is the partial or complete absence of the iris; however, foveal hypoplasia is a more frequent and reliable clinical sign. Other ocular comorbidities are associated

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 ...
