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 ...

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 ...

Measurements of Corneal Biomechanical Properties Using a Dynamic Scheimpflug Analyzer for Young Healthy Adults in South Korea

The human cornea is affected by the magnitude and velocity of both internal and external forces because the cornea has both static and dynamic resistance components. Considering these natures of the human cornea, many investigators have tried to demonstrate corneal biomechanical properties to understand these characteristics of the cornea. Corneal ...

The Incidence and Progression of Myopia: Cohort Study

A prospective cohort study to investigate the refractive error development, progression and their risk factors in young adult population comprises a group of medical students in China for two years

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

The Relationship Between Structure and Visual Function in Myopia Foveoschisis

Macular foveoschisis (MF) is a common complication of pathological myopia, which is characterized by choroid-retinal degeneration and vision impairment. Although pars plana vitrectomy (PPV) is the primary method for MF treatment, there is still a large proportion of recurrent MF due to the extremely long global axial length and posterior ...

Phase N/A

Influence of Posterior Vitreous Detachment on Retinal Detachment After Lens Surgery in Myopic Eyes

Phacoemulsification with implantation of posterior chamber lenses represents the gold standard of care for patients needing lens surgery, but there is an increased risk of developing pseudophakic retinal detachment after surgery. Especially myopic patients have an even higher risk of pseudophakic retinal detachment compared to the general population. The aim ...

Phase N/A

Shanghai High Myopia Study

High myopic cataract (HMC) has become a major high-risky type of cataract in China, which accounts for nearly 30% of cataract in recent years. Compared to age-related cataract, HMC is characterized with earlier onset, severer lens opacities, higher incidence of vitreoretinopathy and postoperative complications compared to age-related cataract(ARC). The main ...
