Spectacle Lenses With Highly Aspherical Lenslets for Myopia Control: A Comprehensive Review of Recent Clinical Trials and Emerging Evidence

Spectacle Lenses With Highly Aspherical Lenslets for Myopia Control: A Comprehensive Review of Recent Clinical Trials and Emerging Evidence

This review synthesizes recent randomized clinical trials and real-world studies confirming the safety and efficacy of highly aspherical lenslets (HAL) spectacle lenses in slowing myopia progression among children, emphasizing comparative effectiveness, visual performance, and long-term outcomes.
Impact of Corneal Posterior-to-Anterior Radius Ratio on Intraocular Lens Power Calculations: Rethinking the Role of Total Keratometry

Impact of Corneal Posterior-to-Anterior Radius Ratio on Intraocular Lens Power Calculations: Rethinking the Role of Total Keratometry

This study reveals that the corneal posterior-to-anterior radius ratio (PAR) influences the refractive prediction differences between standard keratometry (K) and total keratometry (TK) for intraocular lens (IOL) power calculations, underscoring PAR as a potential biomarker for personalized keratometric approaches.
