The relationship between soft contact lens adverse events and corneal sagittal depth

Contact lens wearers with adverse events had a corneal sagittal depth that was significantly shallower than the population mean. These data suggest that one-size-fits-most soft contact lenses may have a sagittal depth that is too deep for patients with a shallower-than-typical corneal sagittal depth, which presumably inhibits the eye's natural defenses. Future studies should compare the relative risk of corneal sagittal depth to other known risk factors and determine clinical guidelines for fitting soft contact lenses based on sagittal depth.
