Purpose: To determine the safety and efficacy of corneal photovitrification (CPV), a new corneal laser procedure, for vision improvement in patients with late-stage dry age-related macular degeneration (AMD).
Design:Â Retrospective observational cohort study
Participants:Â 32 eyes of 17 patients with late-stage dry AMD; each eye received a single CPV corneal laser procedure and had 12 months (12m) post-treatment (Tx) follow-up.
Methods: Pre- and post-Tx examinations included slit-lamp biomicroscopy, subjective manifest refraction, best corrected distance and near visual acuity (BCDVA and BCNVA), and potential visual acuity (PVA). Additional examinations including contrast sensitivity (CS), corneal topography (CT), ray tracing aberrometry (RTA) and microperimetry (MP) were obtained for a subgroup (n=12) of eyes.
Main Outcome Measures:Â BCDVA, BCNVA, PVA, CS, CT, RTA and MP measurements
Results: Safety - There were no complications or adverse events.  Efficacy â Mean (± SD) B...
