Kreps EO, Pesudovs K, Claerhout I, et al. - Researchers conducted this prospective, interventional study to assess the impacts of mini-scleral lenses on visual acuity (VA) and visual functioning in patients with keratoconus. This investigation analyzed the impacts of mini-scleral lenses on VA and visual functioning in patients with keratoconus. Patients under the age of 18 and those who had previously undergone refractive surgery or corneal graft surgery were excluded. Outcome measures were scleral lens–corrected VA and vision-related quality of life as evaluated with the National Eye Institute Visual Functioning Questionnaire (NEI VFQ-39). The research included 89 eyes from 50 keratoconus patients. In patients with keratoconus, mini-scleral lenses significantly improve VA and visual functioning on NEI-VFQ. The most common cause of lens dropout is difficulties with insertion and removal.
