Optical Quality and Visual Performance With Different Toric Contact Lens Designs.

Objectives: To evaluate the optical quality of different toric contact lens (CL) designs and compare their on-eye visual correction performance.

Methods: Twenty soft CL wearers aged 20 to 39 years were enrolled. Two daily disposable silicone-hydrogel toric CLs were tested: the "Eyelid Stabilized Design" (ESD-CL) and prism-ballast design (PB-CL); a spherical daily disposable silicone hydrogel CL (spherical CL) was used as a control.
