Active clinical trials for "Myopia"

The purpose of this study is to compare an experimental contact lens with a currently marketed contact lens.

The objective of this study is to evaluate the clinical performance of two daily disposable contact lenses.

The study compares the precision and accuracy of two laser refractive techniques, PRK and LASIK, for correction of nearsightedness between -6 and -8 diopters.

The aim of this subject-masked prospective study is to evaluate the clinical performance of habitual wearers of Clariti Elite sphere lenses after a refit with Avaira Vitality sphere lenses.

The objective of the study was to compare the clinical performance of the two contact lenses when used in combination with three care systems.

The purpose of this study is to compare the dispensing performance of somofilcon A test 1 day contact lens against somofilcon A control 1 day contact lens.

This is a prospective single-center study of implantations of the presbyopic version of phakic intraocular lens IPCL (EyeolUK, United Kingdom).

The primary objective of the study is to evaluate the clinical performance of test lens (Orion) in comparison with control lens (Gemini) over a period of two weeks of wear.

The objective of the study is to evaluate and compare the performance of study test lens to study control lens, when worn on a daily disposable modality over a period of approximately one week each

The objective of the study is to determine if habitual or adapted contact lens wearers of Omafilcon A can be confidently refit into Somofilcon A lenses and be successful after one week of daily wear. The primary outcome variables for this study are: Investigator responses to refit questions; Lens fit.
