Daily disposable soft lens sagittal depth and other lens parameter changes measured at room temperature (20 °C) and on-eye temperature (34 °C).

Purpose: To investigate the differences in contact lens sagittal depth (CL-SAG), base curve (BC), and overall lens diameter (OAD) of daily disposable (DD) SCLs at room temperature (20 °C) and on-eye (34 °C) temperature.

Methods: Twelve different spherical daily SCLs were analyzed (labeled power -3.00 D) at 20 °C and 34 °C.

Variation in sag values in daily disposable, reusable and toric soft contact lenses.

Purpose: While knowledge of the ocular surface sagittal height (OC-SAG) is increasing with newer instrumentation, understanding of soft lens sag values (CL-SAG) in daily clinical practice is limited. This study aimed to report the differences in CL-SAG of a large collection of daily disposable (DD), reusable (2-week and 4-week replacement) and toric lens designs.

Methods: 12 different spherical DD and 15 reusable lens types were analysed (labelled power -3.
