Active clinical trials for "Myopia"

The aim of this study is to determine if habitual or adapted wearers of stenfilcon A control contact lenses can be refit into test lenses and be successful after one week of daily wear.

This study is a multi-site, group sequential, adaptive, randomized, double-masked, 2×2 crossover design, 1-week dispensing study. Subjects will wear bilaterally both Test and Control lenses in a random order for 1-week each as a daily disposable modality with a wash-out period of 1 week between the wearing periods.

The objective of the study is to evaluate and compare the performance of somofilcon A to etafilcon A when worn on a daily disposable wear modality over a period of approximately one week.

The purpose of this study is to validate the clinical performance of a new contact lens design when worn over a period 1 week compared to nelfilcon A (control).

To compare axial length growth of white European myopic children wearing Menicon Z Night orthokeratology contact lenses to a control group of distance, single-vision glasses and contact lenses over an 11-year period.

Acucela Inc. intends to develop a medical device to significantly halt or reverse myopic progression, which is a significant public health concern across the world, especially in Asian demographics. Acucela is working towards a spectacle-like device (eSPECs), which will have a clear zone for unimpeded central visual tasks and a periphery that provides defocus in order to alter retinal physiology leading to myopia regulation. This study will establish the changes seen during a proof-of-concept that projected defocus in the periphery will stimulate physiological changes similar to those in the literature.

This study is to compare the short-term clinical performance and subjective acceptance of two silicone hydrogel soft contact lenses.

The purpose of this study is to evaluate the clinical performance and subject's preference out of three LRE (Limbal Ring Enhancing) lens types: etafilcon A (Johnson&Johnson), methafilcon A (Interozzo), and methafilcon A (CooperVision).

From July 2015 to December 2015, clinical record of 8 consecutive cases of macular hole with retinal detachment in high myopia treated with combined inverted and free ILM flap insertion into the hole were retrospectively reviewed. The anatomical and function outcomes were assessed.

The purpose of this study is to validate the clinical performance of a new contact lens design when worn over a period of 6 hours compared to nelfilcon A (control).
