Filter by:The aim of this clinical study is to compare the efficacy of DIMS technology spectacle lenses with conventional single vision spectacle lenses at slowing the progression of myopia in the category of children and young adults during three years.
This double-blind, randomized controlled clinical study is to evaluate the effectiveness and safety of low concentration atropine in preventing myopia in pre-myopia children, and to explore whether there is a dose effect relationship between different concentrations of atropine in preventing myopia.
A 2-year prospective, multicenter, randomized controlled, and double-blind clinical trial is used to investigate the efficacy of a new design of ophthalmic lenses to slow the progression of myopia. 300 children aged from 6 to 13 years old will be recruited and randomly assigned to a study or control group. The study group will be composed of 150 children wearing MyoCare while the control group will be composed of 150 children wearing Clearview. The inclusion criteria will be myopia with a spherical equivalent between -0.75D and -5.00D, astigmatism < 1.50D, and anisometropia < 1.00D, as well as having a historical evolution of at least -0.50 The primary outcome is to compare the mean annual progression of the spherical equivalent between both groups. The secondary outcomes are axial length, choroidal thickness, phorias, and accommodative status of both groups.
The Purpose of this study is to explore the safety and effectiveness of SAT-001, a medical device for the treatment of myopia in pediatric patient with myopia
This trial hypothesized that novel laser refractive surgery techniques (PRK, LASIK, SMILE) or laser-assisted cataract surgery (FLACAS) could suppress postoperative inflammation and improve recovery in patients by reducing oxidative stress generated by the surgical procedure. It is also intended to verify whether the new laser technology is necessary for clinical use in groups with low antioxidant activity through the detection of antioxidant activity in the eyes of patients.
This study uses 1.585 double helix defocus lens PC lenses with a unique optical design that includes a globally coherent visible area and complementary left and right helices that can form clear images. In addition, the helical arrangement and reduced slit area can generate defocusing signals, inhibiting the development of myopia. Therefore, based on previous research, this study plans to evaluate the safety and effectiveness of 1.585 double helix defocus lens PC frame eyeglasses in controlling the progression of myopia in children and adolescents through a randomized controlled clinical trial.
To quantify myopic progression (cycloplegic spherical equivalent refraction - cSER) following the cessation of use of specific spectacle lenses. To quantify axial length progression following cessation of use of specific spectacle lenses.
The purpose of this study is to examine the efficacy and performance of the Defocus Incorporated Multiple Segments (DIMS) Spectacle lenses on controlling myopia progression in fast progressing myopic children.
The purpose of this study is to examine the efficacy and performance of the variant of Defocus Incorporated Spectacle lenses on controlling myopia progression in fast progressing myopic children.
The objective is to compare the percentage of monocular UDVA -0.1 logMAR (20/16) outcomes for each planning strategy (Phorcides and manifest refraction) at the 3-month post operative visit.
