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

Topo-guided LASIK and Photorefractive Keratectomy vs Wavefront LASIK and Photorefractive Keratectomy

This study evaluates the difference in results between eyes that have been treated wavefront optimized laser vision correction (either LASIK or Photorefractive Keratectomy) compared to eyes treated with topography-guided laser vision correction (either LASIK or Photorefractive Keratectomy). Each participant will receive wavefront optimized correction in one eye and topography-guided correction ...

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. ...

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

Topography-Guided Customized PRK Versus Q-value Adjusted PRK in Correction of Myopia With or Without Astigmatism

This study will include patients who will undergo PRK in both eyes, for each patient each eye will be randomly allocated to one of 2 procedures: topography-guided ablation in one eye (group I) and Q-factor customized ablation in the other eye (group II). Alcon/Wavelight Light Laser Technologie (GmbH, Erlangen, Germany) ...

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 ...

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

A Study of a New Surgical Treatment of Macular Hole Retinal Detachment in High Myopia

This study uses a new surgical method (vitrectomy combined with inverted internal limiting membrane insertion and intraocular sterilized air tamponade) to assess its effectiveness and safety on the prognosis of macular hole retinal detachment secondary to high myopia, and also compares this new type of surgery with the current commonly ...
