Active clinical trials for "Myopia"

The objective of this study is to determine the clinical feasibility and to evaluate the product performance of an investigational contact lens.

A prospective comparison of eyes undergoing wavefront-guided LASIK in one eye and wavefront-guided PRK in their fellow eye for myopia.

The objective of this study is to determine the product feasibility of the investigational contact lens (Test) when compared to the currently marketed Acuvue Oasys contact lens (Control) and the Air Optix Aqua contact lens (Control) when worn by adapted wearers of soft contact lenses.

The purpose of this study is to assess whether a short-term imposed myopic defocus is effective in preventing the development and progression of juvenile-onset myopia in Chinese children.

To evaluate the effects of exam preparation on anxiety level, self perception, ocular symptoms and oculomotor responses in myopes

Compelling evidence of genetic components in high myopia has been put forward by several studies. Twin cohorts, familial linkage studies and population studies has described at least 10 loci containing genes involved in the disease development. The investigators previously demonstrated novel linkage on chromosome 7q36 and chromosome 7p15 in French families. A new approach consisting of a case-control based population association study is underway in order to recover a high number of myopic subjects avoiding the limitation of familial cases. 1.8 millions polymorphic markers will be compared with emmetropic controls in order to recover loci associated with the disease in the population.

The objective of this study is to evaluate a new daily disposable silicone hydrogel soft contact lens by comparing to an existing daily disposable soft contact lens.

The purpose of this study is to compare the subjective performance for handling of two daily disposable contact lenses, stenfilcon A and etafilcon A.

Clinical Performance of Stenfilcon vs. Filcon II 3

This will be a controlled and randomized, single-masked, crossover study in which 48 subjects will use the Biofinity Contact Lens (comfilcon A) with each of the two lens care products ('solutions'), (Synergi and Biotrue Multi-purpose Solution) for one month each. Follow-up visits for each solution will take place at one week, two weeks and four weeks: with a one-week 'wash-out' period between the solutions. Key outcome measures for this study include biomicroscopic and subjective responses to the lens/solution combinations.
