Active clinical trials for "Astigmatism"

The objective of the study is to compare the clinical performance of two different daily disposable, SiHy toric contact lens types, Lens A and Lens B, in existing soft lens wearers when worn for one week each.

This is a single-center, prospective PMCF study whereby patients undergoing routine cataract surgery will have monolateral implantation of hydrophilic monofocal toric intraocular lens Ankoris.

The principal hypothesis is to be tested in this work is that vision stability (the primary outcome measure) with a spherical contact lens correction vs. a toric contact lens correction will be the same.

The objective of this study is to evaluate the fitting and visual outcomes of Nexis Lens, made of silicone commonly used in the contact lens industry, on healthy eye with or without astigmatism.

This study was conducted to evaluate changes of reduction of corneal astigmatism with toric intraocular lens(IOL) in congenital cataract.

The results of this trial will demonstrate that ISAK performed with the iFS™ femtosecond laser is a safe procedure.

The purpose of this study is to compare the overall performance of a monthly replacement contact lens when worn for one month and when worn for two weeks.

The purpose of this trial was to compare the performance of two contact lenses commercially available for people with astigmatism.

The purpose of this study is to determine the relative performance of a new daily disposable toric soft contact lens against a daily disposable toric contact lens currently available in market, specifically with regards to the comfort and vision with the lens.

The purpose of this study is to investigate the subjective and objective performance of two daily disposable lenses for wearers with astigmatism.
