Magnification correction improves OCTA vascular density accuracy but doesn't significantly enhance structure-function relationships or glaucoma detection, suggesting its limited clinical impact for these specific assessments.

This study found a 1.0mm central hole in phakic IOLs prevents cataract development in porcine eyes by improving aqueous humor flow, suggesting a clinical benefit for human ICL design.

Studying ICLs in pigs, researchers found ICLs without holes disrupt aqueous humor flow to the lens, causing cataracts. Central or haptic holes improve flow, reducing opacities, suggesting design impacts cataract risk.
