Alcohol Myopia Objectification and Sexual Assault

These studies will provide a comprehensive test of our proposed model of alcohol-involved sexual assault that includes situation-specific mechanisms and key moderators of sexual violence. Specifically, hypotheses will be tested in the context of two carefully controlled laboratory studies. In Study 1, laboratory alcohol administration procedures will be used to ...

Phase N/A

Microdosed Atropine 0.1% and 0.01% Ophthalmic Solutions for Reduction of Pediatric Myopia Progression

Subjects will be evaluated for eligibility during an initial Screening Visit and enrolled after signing the study-specific informed consent form(s). Eligible subjects must complete a run-in period where they use the microdose dispenser to administer study drug "vehicle" solution daily in both eyes. After run-in, subjects return for a Baseline ...

Phase

Visual Outcomes for Toric Efficacy Study

This is a crossover study of two types of contact lenses (toric orthokeratology and soft multifocals). Primary aims are to quantify correction of astigmatism, subjective and objective visual performance, aberrometry, peripheral refraction and bacterial bioburden between toric orthokeratology and soft toric multifocal contact lenses.

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

Topography-guided LASIK Surgery

The investigators are analyzing outcomes of topography-guided LASIK surgery in participants with myopia and myopic astigmatism. The investigators will be monitoring changes in anterior segment optical coherence tomography epithelial thickness maps. The investigators will compare preoperative maps to postoperative maps at one, three, six and twelve months. In addition, the ...

Phase N/A

Photorefractive Keratectomy for Severe Anisometropia and Isoametropia Associated With Amblyopia

Anisometropia is a condition in which one eye has a significantly different refractive error from the other and commonly leads to the development of refractive amblyopia in the affected eye. High isoametropia is the condition in which both eyes have high refractive error and commonly leads to bilateral refractive amblyopia ...

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

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

Effectiveness of Myopia Control by Breath-O Correct Orthokeratology Lenses

Myopia is the most common refractive error in the world. In Hong Kong, the number of children in myopia is on the rise and approximately 80% of children are myopic by the end of childhood. Orthokeratology is one of the most successful myopia control methods adopting the strategy of peripheral ...

Phase N/A

The Safety and Efficacy of SYD-101 in Children With Myopia

This will be a 5-arm, multicentered, randomized, double-masked, vehicle-controlled study conducted in 2 parts. Part 1 is the primary treatment period of 3 years, during which participants will receive 1 of 3 masked medications. Part 2 is the randomized withdrawal period of 1 year, during which participants originally receiving Vehicle ...
