An introduction to scleral lenses

S
cleral contact lenses have been a part of management and treatment of corneal disease since the 19th century. Due to
difficulty with manufacturing, improper fitting and poor patient comfort, scleral lenses were not as frequently used as rigid
gas permeable lenses. Significant advances in technology have allowed scleral lenses to become a more important player in the
management of diverse groups of conditions. The development of high Dk lens material, the same used for rigid gas permeable
lenses, has reduced hypoxic related complications that prevented scleral lenses from being the primary lens used for corneal
conditions. These new lenses have increased oxygen permeability, tear flow and are able to vault the limbus appropriately
preventing limbal cell damage. The enhancement in design features of scleral lenses is evidenced by the various eye conditions
treated, including ocular surface disease, keratoconus, pellucid marginal degeneration, post-operative or post-trauma corneal
disease, and irregular astigmatism. By creating a smooth refractive surface, scleral lenses have optimized visual performance
and clarity. Scleral lenses have given patients increased options for visual enhancement without requiring surgery or the need
for glasses. This lecture will guide practitioners through a basic scleral lens fitting starting from lens selection to fit evaluation.
