Previous studies have suggested that central corneal oedema during hydrogel lens wear can be reduced by placing peripheral fenestrations in the lens. In this study, optical pachometry was used to monitor central and peripheral corneal swelling in response to a peripherally fenestrated hydrogel lens. The experiment was conducted in a double-masked, randomized manner on 10 unadapted subjects. Fenestrations did not alter central corneal oedema, but peripheral corneal oedema was reduced by 34% (p > 0.001). Fenestrations may therefore provide a useful strategy for minimizing lens-induced corneal oedema. Clinical trials with fenestrated lenses are now indicated.

Contact lenses for visual rehabilitation in post-keratoplasty eyes: A systematic review.
Cont Lens Anterior Eye
January 2025
Department of Regeneration and Cell Therapy, Andalusian Molecular Biology and Regenerative Medicine Centre (CABIMER), Avda. Américo Vespucio 24, 41092 Seville, Spain.
Purpose: To evaluate the role of contact lenses (CLs) in visual rehabilitation following keratoplasty.
Methods: Four databases, including PubMed, Scopus, Web of Science, and Embase were systematically searched for studies published between January 2010 and July 2023. Visual outcomes, daily wearing duration, subjective comfort, rate and etiology of CL discontinuation, corneal endothelial cell density, central corneal thickness, and complications were extracted.

Background: This study presents the one-year outcomes of a modified technique for transscleral suture fixation of a posterior chamber intraocular lens (PCIOL) in aphakic eyes.
Methods: A retrospective chart review was conducted on 45 patients who underwent transscleral suture fixation of a foldable one-piece PCIOL through scleral pockets. Preoperative data and follow-up data for a minimum of 12 months were collected for all patients.

Approximately 3% of individuals in road traffic accidents suffer ocular injuries. We present a case of a man in his late 80s who presented with bilateral corneal decompensation following airbag deployment during a road traffic accident. Ocular examination revealed multilevel ocular injury with severe bilateral corneal oedema.
