NCT ID: NCT03067077 Completed - Myopia Clinical Trials

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

Start date: March 12, 2017
Phase: N/A
Study type: Interventional

Subjects will undergo SMILE surgery in one eye and LASIK surgery in their other eye to correct myopia.

NCT ID: NCT03063164 Completed - Myopia Clinical Trials

A Comparison of LASIK Outcomes Using Two Femtosecond Lasers

Start date: February 14, 2017
Phase: N/A
Study type: Interventional

Comparing LASIK outcomes using two femtosecond lasers

NCT ID: NCT03026257 Completed - Myopia Clinical Trials

Clinical Assessment of a HYDRAGLYDE® Regimen

Start date: February 13, 2017
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate worn AIR OPTIX® plus HYDRAGLYDE® (AOHG) lenses cleaned and disinfected with HYDRAGLYDE® containing lens solutions compared to each of the control habitual silicone hydrogel (SiHy) lenses cleaned and disinfected with habitual multi-purpose solution (MPS) for cholesterol uptake.

NCT ID: NCT03024970 Completed - Myopia Clinical Trials

Daily Disposable Dispensing Clinical Trial of Test Lens Against Stenfilcon A Lens

Start date: January 2017
Phase: N/A
Study type: Interventional

The purpose of this study is to investigate the overall clinical performance of the test daily disposable stenfilcon A lens with solution additive (test) compared to the stenfilcon A lens (control).

NCT ID: NCT03024073 Completed - Presbyopia Clinical Trials

Assessment of Near Vision Capacity in Different Light Intensities

Start date: January 2017
Phase:
Study type: Observational

Patients who underwent presbyopic correction with bilateral bifocal intraocular lenses implantation are supposed to have sufficient uncorrected vision capacity for activities of daily living (ADLs) that require near vision acuity (NV), (ie. book reading). However, it is known that light intensity and temperature has a great impact on near vision capacity. Primary objective of this study is to identify the optimal task lighting conditions (in terms of light intensity and temperature) for ADLs that demand near vision acuity for a sample oa patients who underwent presbyopic correction with bilateral bifocal intraocular lenses implantation

NCT ID: NCT03023800 Completed - High Myopia Clinical Trials

Effects of Macular Buckle Versus Vitrectomy on Macular Schisis and Macular Detachment in Highly Myopic Eyes

Start date: April 2015
Phase: N/A
Study type: Interventional

Macular schisis associated with macular detachment is a one of the complications of high myopia. There is controversy in the primary treatment for this situation. This study will compare the effects of macular buckling + gas injection versus vitrectomy + internal limiting membrane peeling + gas tamponade in a cohort of highly myopic eyes with macular retinal detachment associated with macular schisis.

NCT ID: NCT03021707 Completed - Clinical trials for Refractive Error - Myopia Simple

Early Feasibility Study of UV-Femtosecond Laser Assisted Lenticular Extraction

Start date: March 7, 2017
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate the initial safety of the UV-FS laser in humans.

NCT ID: NCT03021629 Completed - Clinical trials for Vitamin D Deficiency

Comparison of Vitamin D Status and Vitamin D Receptor Polymorphisms in Patients With High Myopia and Primary Open-angle Glaucoma

Start date: July 2013
Phase: N/A
Study type: Observational

Vitamin D deficiency is known to be significantly associated with high myopia. This study investigated the vitamin D status in patients with high myopia and primary open-angle glaucoma, in order to understand the relationship between high myopia and the development of primary open-angle glaucoma.110 primary open-angle glaucoma patients, 110 high myopia patients and 110 age-matched people in the Han population were enrolled. Serum levels of 1a, 25-Dihydroxyvitamin D3 were measured by an enzyme-linked immuno-absorbent assay.Vitamin D receptor polymorphic analysis was studied by polymerase chain reaction-restriction fragment length polymorphism technique.

NCT ID: NCT02965534 Completed - Clinical trials for Myopia-Night Blindness

Evaluation of a Night Spectacle Correction Concerning an Improvement of Mesopic Vision Quality

Start date: October 2015
Phase: N/A
Study type: Interventional

Reduced quality of vision and glare in twilight or night are frequently mentioned complaints within the optometric examination. A reason for these problems could be a myopic refractive shift in dark light conditions, commonly known as night myopia or twilight myopia. The aim of this study was to investigate whether quality of vision in twilight or night could be improved by a spectacle correction optimized for mesopic light conditions. Moreover, objective refraction in large pupils measured by aberrometry was compared to subjective mesopic refraction.

NCT ID: NCT02956460 Completed - Myopia Clinical Trials

Performance Comparison Between Fanfilcon A and Senofilcon A Sphere Lenses

Start date: October 27, 2016
Phase: N/A
Study type: Interventional

Prospective, multi-center, bilateral, double-masked, randomized, cross-over, daily wear, 1 month dispensing study (2 weeks each lens pair)
