Ocular Response Analyzer Assessment of Intraocular Pressure and Corneal Biomechanical Properties in Myopic and Anisometropic Patients Under Atropine Treatment

Our study has three parts has three parts, and the main aim of the study is to find out if corneal hysteresis was associated with myopia or even a predictor of myopia poor control predictor: - Part 1 of our study: patients with anisomeropia whose spherical equivalent refraction as measured ...

Phase N/A

Study of Myopia Prevention in Children With Low Concentration of Atropine

The prevalence rate of myopia is rising rapidly in several Asian countries. A prevalence survey conducted in 1995 of 11178 school children in Taiwan were 12 percent for six year old and 84 percent for teenagers 16 o 18 years. Among them, twenty percent were high myopes. While in the ...

Phase

Aberration-Free Refraction Correction

The quality of an image on the retina is determined by the optical system of the eyeball, which is dominated by the refractive contribution of the optically powerful cornea. The large difference in refractive index between air and the cornea is the basis for anterior corneal refractive surgery such as ...

Phase N/A

The Role of SNP of ECM and MMP on the Development of Pathological High Myopia

High myopia (pathological myopia) is caused by excessive axial elongation that primarily involves the ora-equatorial area and the posterior pole. Pathological myopia often accompanied by glaucoma, cataracts, macular degeneration, and retinal detachment, leading to blindness when the damage to the retina is extremely severe. Population and family studies in Chinese ...

Phase N/A

The Collaborative Longitudinal Evaluation of Ethnicity and Refractive Error (CLEERE) Study

The Orinda Longitudinal Study of Myopia (OLSM) was started in 1989 to investigate normal eye growth and the development of myopia in over 1,200 school-aged children to date. Beginning in 1997, three parallel study phases are being conducted. Phase 1 investigates additional factors that may predict the onset of juvenile ...

Phase N/A

The Effect of +3.00ADD on Myopia Progression in Chinese Children

The optical intervention has been extensively explored for the intervention of myopia progression. Based on the theory that myopia was caused by the excessive accommodative, bifocal or multifocal spectacles for slowing the progression of myopia have been fully studied. Although some studies' results showed statistically significant for slowing myopia progression ...

Phase N/A

A Comparison of LASIK Outcomes Using Two Femtosecond Lasers

Patients will have a comprehensive eye examination once they express an interest in the study. This includes a slit lamp examination of the front of the eye and a dilated fundoscopic examination of the back of the eye. If there is any pathology noted that would exclude the patient from ...

Phase N/A

A Prospective Contralateral Eye to Eye Comparison of SMILE Surgery to LASIK Surgery

Subjects will have a comprehensive eye examination once they express an interest in the study. This includes a slit lamp examination of the front of the eye and a dilated fundoscopic examination of the back of the eye. If there is any pathology noted that would exclude the subject from ...

Phase

Shanghai Eye Study for Older People

Blindness and visual impairment severely impact the visual health and life quality of people, particularly the 2.566 million senior citizens aged at 65 and above in Shanghai. The main reason is uncorrected refractive error, of which, 62.1% can be solved through refractive correction. For this reason, the uncorrected refractive errors ...

Phase N/A

Low-Dose Atropine for Treatment of Myopia

Study Objectives The objectives for this randomized trial are: To determine the efficacy of daily low-dose atropine (0.01%) for slowing myopia progression over a two-year treatment period in children aged 5 to less than 13 years with myopia -1.00 to -6.00D at the time of enrollment (Primary Outcome On-Treatment). To ...
