Filter by:The purpose of this Post-Market Clinical Follow-Up (PMCF) study is to continuously assess the visual performance and safety of TOTAL30 Sphere and TOTAL30 for Astigmatism contact lenses in a real-world setting across a broad variety of patients through routine clinical practices.
The aim of this study is to compare the short-term clinical performance of two sphere contact lenses.
The objective is to compare the refractive parameters of the photorefraction prototype device without cycloplegia with the refractive parameters of reference device, an autorefractometer with and without cycloplegia.
The purpose of this study is to assess the clinical performance of TOTAL30 for Astigmatism (T30fA) soft contact lenses with Biofinity Toric soft contact lenses.
The primary objective of this study is to evaluate the axis orientation of LID226397 toric contact lenses.
Photobiomodulation therapy, that is, Low-level red-light technology provides a new and innovative myopia control approach. This strategy enables relatively high energies of light to be delivered at much shorter durations of exposure to induce the myopia control effect. The efficacy of the low-level red-light technology has been proven in a Chinese populationb for the recent 3 years with evidence based papers and amazing results. However, there's not yet evidence to demonstrate the relationship between the dose response effect of photobiomodulation therapy on myopia control at the different age lever.
This was a single-blind, interventional, prospective, direct refit, bilateral wear, fixed-sequence crossover study.
The primary purpose of this study is to demonstrate noninferiority in the visual acuity at distance when wearing PRECISION1™ for Astigmatism (P1fA) soft contact lenses compared to another commercially available, soft toric contact lens, MyDay® toric (MDT).
To evaluate the clinical performance of two monthly silicone hydrogel contact lenses in habitual wearers of frequent replacement (FRP) lenses when worn for 1-month.
The purpose of this study is to compare the clinical performance of DAILIES TOTAL1 ( DT1) contact lenses with Infuse contact lenses.
