Efficacy of visual rehabilitation of patients with pellucid marginal degeneration fitted with SPOT® scleral contact lenses.

Summary Purpose To assess visual improvement in patients with pellucid marginal degeneration (PMD) after fitting with SPOT® scleral contact lenses (Scleral Protection & Ocular Treatment, Laboratoires d’Appareillage Oculaire, Amphion-Les-Bains, France). Methods We report a case series of 5 patients with PMD and unsatisfactory refractive correction managed at Clermont-Ferrand university hospital from January to December 2018 fitted with customized SPOT scleral lenses. We assessed the best-corrected visual acuity (BCVA) before and after fitting with SPOT, keratometric data and tolerability of the scleral lenses. Results Nine eyes of 5 patients aged 51.8 ± 8.47 years were fitted. The BCVA was significantly improved from 0.51 logMAR (± 0.39) to 0.04 logMAR (± 0.07) (P  Conclusion Fitting PMD patients who have failed conventional optical devices with SPOT scleral lenses significantly improves BCVA, without serious adverse events, allowing surgery to be deferred even when it appears to be unavoidable.
