Agreement between Two Devices for Measuring Pupil Diameter in Patients Implanted with Multifocal Intraocular Lenses

Vision, 2023
The purpose of this study was to evaluate the agreement between three methods for measuring pupil size in patients implanted with multifocal intraocular lenses (MIOLs): Keratograph 5M (K5M), Pentacam AXL Wave (PW), and a simple hand ruler.

Efficacy and factors influencing toric orthokeratology lenses in managing moderate to high astigmatic myopia

Optometry and Vision Science, Volume 102, Issue 6, Page 387-393, June 2025.
SIGNIFICANCE: Toric orthokeratology lenses show potential in slowing myopia progression in adolescents with moderate to high astigmatic myopia. These findings support the broader application of toric orthokeratology in managing challenging refractive conditions and mitigating myopia‐related complications. PURPOSE: This study seeks to probe the efficacy
