Active clinical trials for "Myopia"

To assess whether Chinese ocular exercise is effective in altering distant and near visual acuity, ocular accommodation and visual symptoms in myopic teenager, and thus might have the possibility of slowing myopia progression in teenager through a weak but long-term effect.

This study aims at investigating the efficacy of myopic control using ortho-k in younger and older children.

The purpose of this study is to evaluate the safety and effectiveness of the Bausch & Lomb Technolas 217z laser with the investigational Zyoptix Aspheric Algorithm when used for LASIK treatment of myopia and myopic astigmatism.

This purpose of this study is to evaluate the safety and effectiveness of a topography-based custom ablation treatment using the ALLEGRETTO WAVE® Eye-Q 400 Hz laser system for treating myopia and hyperopia.

The primary purpose of this study is to investigate the effect of silicone hydrogel contact lenses on conjunctival flora over a period of 6 months of daily wear. A secondary aim is to compare the levels of microbial contamination of silicone hydrogel lenses after daily wear.

The objective of this clinical investigation is to evaluate the safety and efficacy of the Vedera KXS in sighted eyes for the correction of spherical myopia.

The purpose of this study is to evaluate two different types of contact lenses and their effect on dry eyes when compared to wearing glasses in a controlled, low humidity chamber.

To assess how well and safe is Neurovision technology in improving the vision of people with low myopia in Singapore

Phakic intraocular lenses (pIOL) have proven to be a great alternative to corneal refractive surgery in certain situations. They offer several advantages over corneal techniques, such as being suitable for high myopes and causing relatively fewer higher-order aberrations. In addition, pIOLs have been shown to provide better retinal image magnification and higher contrast sensitivity compared to laser in situ keratomileusis, regardless of whether the myopia is low or high.

To evaluate the performance of two monthly replacement silicone hydrogel contact lenses in habitual FRP CL wearers when worn for 1-month.
