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 ...

Mathematical Modeling of IOL Power Changes After Pupil Dilation Based on Multifactorial Analysis

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose This study aimed to explore the factors affecting the changes in intraocular lens (IOL) power after pupil dilation in patients with age‐related cataract and to construct linear regression models. Methods A total of 167 patients with age of 66.47 ± 8.63 (years) were included in this study to evaluate whether pupil dilation led to significant ...
