Active clinical trials for "Refractive Errors"

The purpose of this study was to assess the comfort of OPTI-FREE RepleniSH in soft contact lens wearers.

This clinical trial will document the feasibility of the Apioc lens design by assessing which lens shape parameters yield successful on-eye-fit and movement of the Apioc contact lens design and evaluate the subjectively-reported comfort of the Apioc contact lens design.

The purpose of this study was to determine whether ocular surface sensitivity to pneumatic, mechanical and chemical stimulation would be affected by the use of the combination of a specific silicone hydrogel lens material with two lens care products over a four week period.

The purpose of this study is to determine if reduced lens deposits and increased comfort can be achieved by using Multipurpose disinfecting solutions (MPDS) in a no-rub format but in conjunction with an intensive cleaner, rather than using MPDS in a rub format.

The aim of this prospective study is to evaluate the clinical performance of habitual wearers of methafilcon A aspheric lenses after a refit with fanfilcon A sphere lenses for 4 weeks of daily wear.

The purpose of this study is to evaluate the rotational behavior of DT1 Toric contact lenses.

Primary objective of this study was to compare the efficacy of premium monovision with Restor and Panoptix, against other prevalent monovision techniques and against bilateral Panoptix implantation in a sample of patients following lens-extraction surgery.

A prospective, self-control, double-blind design was conducted in Tianjin. Two hundred participants were assigned to wear two kinds of spectacle glasses. To examine the effect of free-toroidal design and aspherical lens on the subjective visual quality among the myopic population.

The purpose of this study is to evaluate AIR OPTIX® plus HYDRAGLYDE® (AOHG) contact lenses compared to AIR OPTIX® AQUA (AOA) contact lenses in overall lens fit.

The purpose of this study is demonstrate substantial equivalence of an investigational contact lens disinfecting solution to a commercially available contact lens solution in silicone hydrogel and soft contact lens wearers.
