Purpose: The aim of this study was to evaluate fitting characteristics of ICD FlexFit scleral lens using slit lamp biomicroscopy (SLB) and anterior segment optical coherens tomography (AS-OCT) and to investigate its early outcomes in patients with keratoconus.
Setting: Department of Ophthalmology, Ankara University School of Medicine, Ankara, Turkey
Methods: Files of consecutive patients with keratoconus who were fit with ICD FlexFit scleral lens were retrospectively evaluated. Following detailed opthalmological examination, demographic data, stage of keratoconus, visual acuities, SLB and AS-OCT measurements during initial scleral lens fitting process as well as patient comfort were evaluated.
Results: Scleral lenses were fit on 21 eyes of 14 patients with mean age of 33.6±10.8 years. Fourteen patient eyes had stage IV, 1 patient eye had stage III, 5 patient eyes had stage II, and 1 patient eye had stage I keratoconus according to Amsler Krumeich classification. The mean uncorrected and corrected visual acuities were 1.15±0.46 and 0.21±0.12 logMAR respectively. The central corneal clearance 15 minutes and 2 hours after lens fit were 332.04 ±113.7 and 284.57±87.9 µm. All cases had adequate limbal clearance, no mid-haptic compression, optimum edge alignment at SLB and AS-OCT assessment. Ideal lens fit was achieved with 1 trial lens in 18 patient eyes, 2 trial lenses in 3 patient eyes. Lens comfort was evaluated as ‘very good’ to ‘excellent’ by all patients.
Conclusion: ICD FlexFit scleral lens fit seems to be easy and time saving with ideal lens fit being achieved with only 1 to 2 trial lenses. The lenses seem to provide excellent patient comfort and visual outcomes at the time of fitting.
