First Experience With the ICD 16.5 Mini-Scleral Lens for Optic and Therapeutic Purposes

OBJECTIVES To evaluate the success rate, efficacy, and safety of the ICD 16.5 mini-scleral gas permeable (GP) contact lens. METHODS This prospective study included referred consecutive patients with irregular corneas and severe ocular surface disease (OSD) in treatment failure. All patients were fitted with the ICD 16.5 mini-scleral GP lens. Even though we had some limited experience with scleral lenses, it was our first experience with the ICD 16.5 mini-scleral GP lens. Efficacy was assessed by comparing best-corrected visual acuity (BCVA) with the mini-scleral lens to baseline BCVA. A subjective visual functioning questionnaire (comfort score, visual quality score, handling rating, and wearing time) was administered in a face-to-face structured interview. RESULTS Thirty-nine eyes of 23 patients with a mean age of 43±16 years were included. Fitting indications were keratoconus (46%), post-penetrating keratoplasty (21%), other irregular astigmatism (15%), and severe OSD (18%). Twenty-five eyes (64%) were successfully fitted with an 18-month follow-up. The mini-scleral GP lens BCVA was 0.16 logarithm of the minimum angle of resolution (logMAR; 20/25) versus a baseline BCVA of 0.44 logMAR (20/63; P
