This study aimed to evaluate the improvement in quality of life for patients with keratoconus fitted with scleral lenses, showing that visual acuity and NEI-VFQ 25 scores improved significantly after fitting. Factors such as disease severity and visual gain were found to be associated with improvements in quality of life.
Objectives: To assess the quality-of-life improvement after scleral lens fitting in patients with keratoconus. Methods: We conducted a prospective observational study of all consecutive patients with keratoconus starting scleral lens fitting in 2019, from January 2 to December 27, at the Dijon University Hospital, France. Quality of life was assessed before and after wearing scleral lenses for 3 months through the National Eye Institute Visual Function Questionnaire 25 (NEI-VFQ 25) questionnaire. We investigated factors potentially influencing quality of life: final visual acuity, keratoconus stage, and maximum keratometry reading. Results: In total, 41 eyes of 24 patients were successfully fitted with scleral lenses, 92.9% were 18 mm in diameter and 7.1% were 17 mm. The visual acuity improved by -0.4 +/- 0.3 logarithm of the minimum angle of resolution (P<0.001) after scleral lens fitting. Visual gain increased with keratometry and keratoconus severity (PP<0.01). The NEI-VFQ 25 score increased by 19.5 +/- 19.1 points on average (P<0.001). No association was found between the factors under study and improvement in quality of life. Conclusion: Our study confirms the functional improvement in patients with keratoconus fitted with scleral lenses, especially in patients with more advanced disease. Moreover, it suggests a major role of these lenses in improving quality of life, independently of the severity of the disease and the visual gain.
