Corneal epithelial bullae after short-term wear of small diameter scleral lenses.

•Scleral lens bearing on the cornea can cause a variety of corneal changes.•OCT imaging is useful to objectively describe scleral lens fitting relationships.•Multiple OCT images are needed to comprehensively describe a scleral lens fitting relationship.•The distribution of scleral lens touch may alter the likelihood of corneal damage .•Corneal epithelial bullae can appear from mechanical damage in scleral lenses.
