Central Vault in Dry Eye Patients Successfully Wearing Scleral Lens

Purpose. Scleral contact lenses are used to treat symptoms of severe dry eyes. Procedures for fitting scleral lenses have been vague because of lack of standardized guidelines. This retrospective case series sought to establish average vault over central cornea in successful scleral lens wearers with dry eyes. Methods. Anterior segment optical coherence tomography was used to measure the distance between the posterior lens surface and cornea in 20 eyes of 12 consecutive patients successfully fit in the Vanderbilt Scleral Lens Clinic. Results. Mean vault was 380 +/- 110 mu m. There was no correlation between vault and corneal curvature or vault and visual acuity. Conclusions. With a large SD in average vault, precision in central vault does not seem to be important in scleral contact lenses for successful fit for dry eyes.
