Qualité de vie des patients équipés en verres scléraux

We included 47 patients (83 eyes) fitted with scleral lenses on one or both eyes: 56 eyes with keratoconus and 27 post-keratoplasty eyes. The average duration of wearing scleral lenses was 18 ± 10 months and the average wearing time was 14 ± 3 hours per day. The rate of participation in the survey was 86.5% (41 patients). Visual acuity in the better eye progressed from 0.68 ± 0.46 to 0.15 ± 0.17 logMAR at the 6th month after scleral lens adaptation (P < 0.0001). The average scores on the NEI-VFQ 25 questionnaire of patients fitted with scleral lenses for at least 6 months were significantly higher than those without scleral lenses, with a global score of 80.2/100 with, versus 48.1/100 without, scleral lenses (P < 0.0001). The global score increased by an average of 32.1 ± 4.6 points (−28, 82) (P < 0.0001). Statistical analysis found no significant difference in global score between patients in the keratoconus and keratoplasty groups (P > 0.05). Scleral lenses showed a significant improvement in quality of life for patients who had failed or are intolerant to conventional rigid gas permeable contact lenses. In our two main optical indications, keratoconus and keratoplasty, they represent an alternative or a step prior to surgery.
