Revisiting Minimal Solver of Camera Triplets for Incremental Structure‐from‐Motion

The Photogrammetric Record, Volume 41, Issue 193, January–March 2026.
Left: Overview of T2vP, a minimal solver for camera pose estimation requiring as few as six pure 2D correspondences, without relying on three‐view overlap. Right: T2vP successfully registers cameras in challenging scenarios where PnP solvers fail, as three‐view points are insufficient due to large viewing angle discrepancies.

Through-Focus Vision Performance and Light Disturbances of 3 New Intraocular Lenses for Presbyopia Correction

Journal of Ophthalmology, 2018
Purpose. To compare the through-focus visual performance in a clinical population of pseudophakic patients implanted with two new trifocal intraocular lenses (IOLs) and one extended depth of focus IOL. Methods. Prospective, nonrandomized, examiner-masked

Assessment of a New Trifocal Diffractive Corneal Inlay for Presbyopia Correction Using an Adaptive Optics Visual Simulator

Photonics, 2022
In this work, we analyze a proposal of a new intracorneal diffractive lens for presbyopia correction that could allow good, distance, intermediate and near vision. By using an adaptive optics visual simulator, we study the influence of two factors in the

Association Between Lens Thickness and SRK/T Refractive Prediction Error After Cataract Surgery: A Single‐Center Retrospective Cohort Study

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To evaluate the association between lens thickness (LT) and SRK/T refractive prediction error following cataract surgery and to analyze its underlying mechanism. Methods This retrospective cohort study collected data from patients who underwent surgical treatment for age‐related cataracts between January 2025 and June 2025.

Visual Outcomes and Patient Satisfaction After Implantation of Enhanced Versus Standard Monofocal Intraocular Lenses With a Myopic Target Refraction: A Retrospective Comparative Study

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To compare the clinical outcomes of enhanced monofocal IOL (Eyhance) and monofocal IOL (TECNIS) implantation in cataract patients whose target refraction is myopia. Methods This is a retrospective chart review for patients who underwent cataract surgery and whose target refraction is myopia (−3 D).
