Clinical Performance of a New Bitangential Mini-scleral Lens.

Significance: New bitangential mini-scleral lens designs provide a highly precise fit, follow the scleral shape, are comfortable to wear, and can correct residual astigmatism. This new scleral lens design complements the arsenal of medical contact lenses available to eye care practitioners.

Purpose: The aim of this study was to evaluate the subjective and objective performance of a new mini-scleral lens design with a bitangential periphery.

Medical applications and outcomes of bitangential scleral lenses.

Purpose: To evaluate the clinical results of a new scleral lens design with a bitangential (nonrotationally symmetrical) periphery.

Methods: All the necessary data were obtained during the 1-year study period. The bitangential scleral lenses were fitted and monitored according to a standardized fitting methodology.

Modern scleral lenses part II: patient satisfaction.

Purpose: To evaluate the subjective performance of modern scleral lenses in patients of the clinics of Visser Contact Lens Practice.

Methods: In this cross-sectional survey, all the necessary data were collected at the first follow-up visit during the 5-month study period. In accordance with the preformed fitting technique developed at Visser Contact Lens Practice, four types of scleral lenses were used: spherical, front-surface toric, back-surface toric, and bitoric.

Modern scleral lenses part I: clinical features.

Purpose: To evaluate the indications for modern scleral lenses and their clinical performance in patients who were fitted with scleral lenses at the authors' practices.

Methods: In this cross-sectional survey, all the necessary data were obtained at the first follow-up visit during the 5-month study period. There were four types of scleral lenses: spherical, front-surface toric, back-surface toric, and bitoric.
