Active clinical trials for "Refractive Errors"

The purpose of this clinical study is to evaluate the on-eye performance of an investigational soft contact lens compared to a commercially available soft contact lens following 1 week of extended wear.

This is a single-site, two-visit, contralateral, non-dispensing, randomized, controlled and subject-masked study to measure potential benefits of the new UV blocker.

The purpose of this study is to evaluate the visual performance of DAILIES® AquaComfort Plus® (DACP) Digital lenses by assessing distance visual acuity (VA) as compared to DACP sphere contact lenses after one week of wear.

The Lentechs Apioc-S and Apioc-A contact lenses are made in an FDA-approved contact lens material indicated for single-vision and astigmatism. The novel lens design has a lenticular portion which is thicker than the optical portion of the lens. When applied to the eye, it is oriented in a superior position. Unlike contact lenses currently on the market, this innovative design improves lens stability by preventing lens rotation, and may improve tear flow behind the lens.

There is a great need for precise and repeatable measurements of the choroidal thickness. Including the diurnal physiological changes, accommodation and refractive error impact on those measurements.

The purpose of this study was to evaluate visual acuity at distance when wearing DDT2 contact lenses compared to Acuvue Moist contact lenses.

The primary objective of this study is to evaluate the overall clinical performance of an investigational silicone hydrogel contact lens over 7 days of daily wear.

The primary objective of this study is to evaluate the overall performance of an investigational silicone hydrogel lens when compared to ACUVUE OASYS® with HYDRACLEAR® PLUS (AOHP).

The primary objective of this study is to evaluate the overall clinical performance of an investigational silicone hydrogel contact lens over 2 weeks of daily wear.

The study will compare the short-term clinical performance and wearer and practitioner acceptability of a new-to-market spherical daily disposable (DD) hydrogel soft contact lens to a currently marketed spherical DD hydrogel soft contact lens.
