Abstract: To evaluate the effect of mini scleral contact lenses and corneal rigid gas permeable (RGP) keratoconus lenses on the quality of life (QoL) of patients with keratoconus (KCN), using self-reported data from the Contact Lens Impact on Quality of Life (CLIQ) Questionnaire.
Methods: Between January 2023 and May 2023, a total of 124 consecutive keratoconus patients who used either mini scleral or corneal RGP contact lenses were assessed using the CLIQ questionnaire. Demographic and clinical characteristics, including age, sex, visual acuity and keratometric (K) values, were recorded for all participants.
Results: The study population had a mean age of 28.7 ± 7.2 years. Among the participants, 61 were mini scleral lens users. Both groups were comparable in terms of age, sex, and mean K values (P=0.1, P=0.8, and P=0.1, respectively). The mean CLIQperson score was significantly higher in the mini scleral contact lens group (56.7 ± 5.6) compared to the corneal RGP lens group (43.5 ± 6.2; P ≤ 0.01). Additionally, the CLIQperson measure showed a positive correlation with K values and visual acuity. When stratified by visual acuity, eyes with visual acuity of 20/20 to 20/25 had a mean CLIQperson score of 52.12 ± 6.6, whereas eyes with visual acuity of 20/32 or worse had a mean score of 41.4 ± 5.3 (P ≤ 0.01).
Conclusion: The findings indicate that mini scleral contact lens users report a higher quality of life compared to users of corneal RGP lenses. This suggests that mini scleral lenses may offer greater satisfaction and comfort for keratoconus patients.
