Purpose:
The purpose of the study is to evaluate the visual outcomes and improvement in quality of life (QOL) of patients with keratoconus with scleral lenses.
Methods:
In this prospective study, 14 patients (28 eyes) with bilateral keratoconus were fitted with scleral lenses (McAsfeer 16.00 mm) in Pune city, Maharashtra, India. Uncorrected visual acuity (VA), best spectacle-corrected VA, and VA with scleral lenses were evaluated. The patients were given the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25) for judging the QOL, before and after using scleral lenses for 3 months.
Results:
The mean uncorrected VA of the 14 patients with a mean age of 28.64 ± 6.57 years was 1.18 ± 0.19 logMAR. Best spectacle-corrected high-contrast VA improved from 0.47 ± 0.25 logMAR to 0.03 ± 0.07 logMAR with scleral lenses (P < 0.001). Best spectacle-corrected low-contrast VA improved from 0.68 ± 0.22 logMAR to 00.47 ± 0.10 logMAR with scleral lenses (P < 0.001). Along with the increase in overall median scores on the NEI VFQ-25 from 1735 to 2930 points (P < 0.001), the distance and near activities (P < 0.001), vision-specific mental health (P < 0.002), social functioning (P < 0.004), and driving (P < 0.005) improved after using scleral lenses for 3 months.
Conclusion:
Scleral lenses can be an effective and safe management option for patients with keratoconus leading to an improved vision and QOL.
