Filter by: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.
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).
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
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.
The purpose of this study is to evaluate the initial safety of the UV-FS laser in humans.
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.
The objective of this study is to evaluate the safety and effectiveness of the Raindrop Near Vision Inlay implanted in bilateral pseudophakes with presbyopia for improvement of near and intermediate vision. The ReVision Optics corneal inlay is a 2.0-mm, 30-micron inlay made of a hydrogel material, implanted under a lasik flap. Subjects must require reading add from +1.50 D to +2.50 D. Subjects must have a preoperative manifest refraction spherical equivalent of -0.50 to +1.00 D with no more than 0.75 D of refractive cylinder. The Raindrop Near Vision Inlay will be implanted in the non-dominant eye.
This study aims to determine the treatment effect of vision therapy on myopic children by assessment of accommodative function before and after therapy.
The proposed study seeks to compare visual acuity, tomographic outcomes, biomechanical changes and inflammatory profile of normal eyes (matched for age, refraction and corneal thickness) undergoing iDesign and SMILE procedure. The hypothesis is that iDesign may deliver equivalent or better clinical outcomes than SMILE, by removing less tissue and correcting for higher order aberrations.
The purpose of this study is to compare Topography Guided Laser In Situ Keratomileusis (LASIK) corneal surgery to Small Incision Lenticule Extraction (SMILE) corneal surgery for the treatment of myopia with astigmatism.
