Active clinical trials for "Myopia"

Evaluation of Johnson & Johnson Acuvue Vita (senofilcon C) soft contact lenses to the Bausch + Lomb Ultra (samfilcon A) soft contact lenses

The purpose of this study is to validate the clinical performance of a new contact lens design.

The purpose of this study is to compare the clinical performance of TOTAL30 contact lenses with Biofinity contact lenses over 30 days of daily wear.

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 utilizing a wearable device will stimulate physiological changes similar to those in the literature.

The objective of the study is to measure the difference in the lag of accommodation between DOT spectacle lenses and control spectacles.

The purpose of this study is to evaluate the performance of Precision1 DD CLs with regard to subjective symptoms (dryness, comfort, vision), lens fit and time to haze in CL wearers who identify themselves as heavy digital devices users (at least 6 hours of digital device use per day).

The purpose of this study is to compare ACUVUE® ADVANCE® Plus contact lenses made prior to process qualification (prePQ) against the ACUVUE® ADVANCE® Plus lenses made after the process qualification (postPQ).

The purpose of this research is to measure daytime open-eye response to wearing of narafilcon B lenses.

By using a new software two consecutive laser treatments have been combined to correct the distance vision and to provide a near vision component in addition to the first treatment. This study will help us to answer 2 questions: How accurately this combined technique corrects distance and near vision Whether the correction is adequate to remove the complete need for supplementary near spectacles

Subjects with myopia, hyperopia and astigmatism are being randomized to be treated in one eye with a wavefront-guided excimer laser and their fellow eye treated with a wavefront-optimized excimer laser.
