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

Surgical 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.

Refining laissez‐faire treatment of periocular tumour defects by exploring the impact of defect localization and geometry on the healing process

Acta Ophthalmologica, EarlyView.
Abstract Background Large lower eyelid defects resulting from tumour removal are frequently reconstructed using a tarsoconjunctival flap from the upper eyelid together with an overlying free skin graft, the so‐called Hughes procedure. One disadvantage of this technique is that the tarsoconjunctival flap occludes the eye during the revascularization of ...

Anterior chamber flare and central macular thickness after trabeculectomy versus after phacoemulsification

Acta Ophthalmologica, EarlyView.
Abstract Purpose To compare the inflammatory response in the eye after trabeculectomy to after phacoemulsification, focusing on anterior chamber flare (AC flare) and central macular thickness (CMT). Methods Data from 436 participants in two randomized controlled trials were analysed.

Effect of chilled eye drops on postoperative pain sensation after phototherapeutic keratectomy: Randomised controlled clinical trial

Acta Ophthalmologica, EarlyView.
Abstract Purpose To analyse pain sensation after phototherapeutic keratectomy (PTK) using chilled eye drops or drops at room temperature during the early postoperative period. Methods Our randomised controlled, parallel‐group study conducted in the Department of Ophthalmology, Goethe‐University, Frankfurt (Main), Germany, with blinded participants and ...

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)

Acta 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.

Interpreting the structure–function relationship in high myopia‐associated glaucoma: A review

Acta Ophthalmologica, EarlyView.
Abstract Visual field (VF) interpretation in high myopia‐associated glaucoma (HMG) is challenging due to frequent structure–function discordance and coexisting myopia‐related changes. These changes may reduce the reliability of conventional structure–function mapping and increase the risk of misclassifying non‐glaucomatous VF abnormalities as ...

Genetic risk factors in Finnish patients with Fuchs endothelial corneal dystrophy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To study the genetic risk factors of Fuchs endothelial corneal dystrophy (FECD) in the Finnish population using hospital‐based and large biobank cohorts. Methods We genotyped a cohort of 107 Finnish patients with FECD for the primary associated genetic risk factor, the TCF4 (CTG)>50 expansion, and studied their clinical phenotype.
