Poster Abstract

Purpose
To determine the primary indications, outcomes, and complications in patients fitted with custom 3-D scanned EyePrint PRO (EPP) scleral contact lenses (SCLs).
Methods
A retrospective medical chart review identified all patients at the University of Iowa Hospitals and Clinics fitted with EPP SCLs between December 2013 and March 2018. Demographics, fitting indication, and lens use history were determined at baseline. Patients were followed for the duration of charted EPP use. Primary outcome measures included best corrected visual acuity (BCVA) measured at all visits, and complications of EPP use. Visual acuities were converted to log MAR for statistical analysis. Significant differences between BCVA before and after EPP fitting were determined by Wilcoxon sign ranked test.
Results
In total, 89 eyes from 70 patients were followed for a median of 11.1 months (IQR 4.4-18.6). Median age at fitting was 52.2 years and 46 (66%) patients were prior contact lens users. Primary indications were irregular corneal shape including ectasia (66%), surface disease (17%), exposure (10%), neurotrophic keratitis (9%), conjunctival or scleral abnormalities (9%), and corneal scarring (4%). Mean BCVA improved from 0.63 to 0.03 (p<0.0001). Thirty-four (49%) patients developed complications and device cessation occurred in 8 (11%) patients unrelated to prior lens wear or indication. Patients requiring lens reprinting (19%) were more likely to stop lens use than those who did not (p=0.03).
Conclusion
EPP SCLs improved BCVA in patients with varying primary indications and lens use history. Nearly half of all eyes developed complications, but this event was not associated with lens use history or indication. EPP lens reprinting may be predictive of ultimate device failure.
