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.

Objective and subjective evaluation of the performance of medical contact lenses fitted using a contact lens selection algorithm.

Purpose: To evaluate the performance of medical contact lenses (CLs) for a wide range of clinical indications.

Design: Prospective cross-sectional study.

Methods: A total of 281 eyes were evaluated in 281 consecutive patients (≥18 years of age; CL use ≥3 months) who visited the contact lens service in a tertiary academic clinic for a scheduled follow-up visit.

Scleral lens influence on corneal curvature and pachymetry in keratoconus patients.

Objectives: To investigate the influence of full scleral lenses on corneal curvature and pachymetry in keratoconus patients.

Methods: In this intervention study, 20 eyes of 14 patients were measured by Scheimpflug imaging (Pentacam HR, Oculus) at two time points: directly and ≥1 week after scleral lens removal. Steep, flat and maximal keratometry (K(steep), K(flat) and K(max)) and optical pachymetry were analyzed.

Scleral lens tolerance after corneal cross-linking for keratoconus.

Purpose: Subjective and objective evaluation of scleral lens tolerance and fitting before and after corneal cross-linking (CXL) for progressive keratoconus.

Methods: In this prospective cohort, evaluations were made of 18 unilateral eyes in patients who underwent CXL and had been wearing scleral lenses before the procedure. All the patients gave informed consent; they were able to cooperate with the study, were eligible for CXL, had been wearing well-fitting scleral lenses for at least 3 months, and had no other active ocular disease.

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.

Advantages of toric scleral lenses.

Purpose: The purpose of this study was to investigate whether back surface toric scleral lenses stabilized (i.e., returned to their original position after rotation) and how long the return times were.
