Case report of a rapidly progressing monocular keratoconus over two years

Keratoconus, the non-inflammatory, progressing, thinning disorder of the cornea, is characterized by diminishing unaided visual acuity and increasing dependence on professional treatment. We report the management of over two years of a 25-year-old monocularly keratoconic male whose disease progression was unusual in that it was remarkably rapid. During the 28 months, the patient's flat-K increased by 3.00 diopters and his steep-K increased by 4.00 diopters. Our lens design and treatment, using the Rose K design rigid gas-permeable lenses, is detailed in this report. Corneal topographies documenting the ectatic progression, as well as a model three-point touch fit, are also shown. Continued monitoring of the patient is still underway as his keratoconus has not yet stabilized.
