The range of contact lens modalities currently available for the successful optical correction of keratoconus is greatly expanded. We review lens types currently available for the nonsurgical management of keratoconus, including rigid gas-permeable (GP) lenses, intralimbal lenses, corneoscleral lenses, scleral lenses, hybrid lenses, and piggyback lenses. In this review, we discuss the contemporary range of available lens types and the circumstances in which they are best used.

We hypothesize that the stage of life at which keratoconus commonly presents plays a crucial role in personality and coping mechanism development that significantly affects behavioral patterns and the relationship with caregivers.

Scleral lenses are effective and safe in patients who have had PK. There was a mean gain in visual acuity, with the majority of patients achieving 20/40 vision or better. The patient's subjective perception of vision was a significant factor in determining whether scleral lens wear was continued or abandoned.
