Mapping the lineage of prostate tissue ablation medical device predicates for focal therapy of prostate cancer approved via the FDA 510(k) clearance pathway

open access: yesSurgical Practice, EarlyView.
Abstract Objective Medical devices are reviewed by the US Food and Drug Administration (FDA) for safety and effectiveness. Class II devices can receive 510(k) clearance if they are “substantially equivalent” to an existing predicate device. This process can be repeated iteratively, leading to a lineage of predicates for newly cleared devices.

Impact of mono‐ or multitherapy on ocular surface health and quality of life after 5 years of follow‐up in the Glaucoma Intensive Treatment Study (GITS)

open access: yesActa Ophthalmologica, EarlyView.
Abstract Aim To evaluate the impact of initial mono‐ versus multitherapy on the ocular surface and related quality of life after 5 years follow‐up in the Glaucoma Intensive Treatment Study (GITS). Method The study included patients with primary open‐angle glaucoma and pseudoexfoliation glaucoma who completed 5‐year follow‐up in GITS.
