Comparisons of Intraocular Lens Calculation Formulas for Eyes With Astigmatism: Systemic Review and Network Meta‐Analysis

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To compare the accuracy of different formulas for calculating toric intraocular lens (IOL) power. Methods PubMed, EBSCO, Web of Science, and the Cochrane Library were systematically searched for studies published from 2015 to 2025. Numbers of eyes with a prediction error (PE) within ±0.50 and ±1.00 diopters (D) were synthesized for the meta ...

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
