Environmental Health and Myopia Prevention and Control

Myopia is one of the major causes of low visual acuity during childhood. It is generally more prevalent in urban areas than in rural areas. Current evidence does not address our understanding of the myopia incidence and development and associated risk geographic factors, such as green spaces. Therefore, our study ...

Phase N/A

Clinical Applications of Advanced Ophthalmic Imaging

This study to determine the clinical application of advanced ophthalmic imaging devices such as optical coherence tomography (OCT), retinal function imager (RFI), slit-lamp biomicroscopy (SLB), PERG in diseased eyes and normal controls.

Phase N/A

Evaluation of Cataract Surgery Outcome

The purpose of this study is to evaluate the visual outcome of the cataract surgery, including best uncorrected and corrected visual acuity, spherical equivalent, wavefront aberration and other measurements.

Phase N/A

Ocular Development and Refractive Error Changes Among Children and Adolescent - A Longitudinal Study

This study aims to observe the refractive error changes of school children and adolescents for 3 years, and to collect data of ocular structural parameters, family history and environmental factors so as to understand the natural course and internal laws of myopia progression.

Phase N/A

Development and Pathological Changes of High Myopia Among Children and Adolescents in China

This study aims to observe children and adolescents with high myopia for 3 years, and to collect data of ocular pathological changes, family history and environmental factors so as to understand the natural course and internal laws of the development of high myopia.

Phase N/A

Long Term Effects of Multifocal Orthokeratology on Corneal and Choroidal Structures in Healthy Subjects With Myopia- A Pilot Study

Orthokeratology has the benefit for slowing down myopia progression and enabling unaided vision during the day. To investigate proposed possible changes of conventional and multifocal orthokeratology in the cornea and choroid this study will image both structures with high resolution optical coherence tomographs over a six month period. Findings will ...

Phase N/A

Effects on Ocular Parameters of Myopic Eyes After Orthokeratology in Myopic Children

1.The primary objective of the current study is to investigate changes in uncorrected visual acuity, diopter, accommodation, peripheral refraction, IOP, tear film quality, corneal thickness, corneal topography, corneal biomechanical parameters, objective optical quality, corneal and conjunctiva sensitivity and choroidal thickness for children with different diopters after wearing orthokeratology lenses; 2. ...

Phase N/A

An Evaluation of LASIK SMILE and PRK Surgery in Physicians

The participants 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 participant ...

Phase N/A

Shanghai High Myopia Study for Adults

High myopia retinopathy has become the first cause of irreversible blindness and severe visual impairment in Chinese adults, in order to avoid the blind and visual impairment caused by high myopia retinopathy, it is very necessary to research the mechanism of early visual impairment to prevent and control damages. Our ...

Phase N/A

Advanced Surface Ablation (ASA) vs Laser-Assisted In Situ Keratomileusis (LASIK)

Excimer laser vision correction (LVC) is a widely used procedure to correct nearsightedness, farsightedness, and astigmatism by reshaping the surface of the eye (cornea). Laser-Assisted In Situ Keratomileusis (LASIK) and Advanced Surface Ablation (ASA) and are techniques currently used to prepare the cornea for Excimer LVC. This review is intended ...
