Filter by:The primary objective of the study is to evaluate the clinical performance of test lens (Orion) in comparison with control lens (Gemini) over a period of two weeks of wear.
The principal hypothesis is to be tested in this work is that vision stability (the primary outcome measure) with a spherical contact lens correction vs. a toric contact lens correction will be the same.
The primary objective of this study is to evaluate the overall performance of PRECISION1 contact lenses when compared to Clariti 1-Day contact lenses.
The primary objective of this study is to evaluate the overall performance of PRECISION1 contact lenses when compared to Biotrue ONEday contact lenses.
Being short sighted means that vision is blurry when looking at things far away. People with a condition called "pathologic myopia" are short sighted due to problems in the back layer of their eyes, also known as the retina. Some people with pathologic myopia can develop a serious condition called myopic choroidal neovascularization (mCNV). In people with mCNV, new blood vessels grow into the retina. These blood vessels can break, leaking blood or fluid into the retina. This can cause blurry vision or a loss of vision. In this study, researchers will find out more about how well drug aflibercept works and how safe it is in Canadian patients with mCNV. The researchers in this study will review information from the patients' eye doctor visits. The patients in this study will include Canadian men and women who started receiving aflibercept between May 2017 and August 2019. These patients were at least 18 years old and had not received treatment for their mCNV before. The researchers will look at the results of vision tests to find out how well the patients could read from a distance after they received aflibercept for 6 months. They will compare the results of these tests to before the patients received treatment. They will also learn more about how safe it is to have aflibercept injection into the eye.
The objective of the study is to evaluate and compare the performance of study test lens to study control lens, when worn on a daily disposable modality over a period of approximately one week each
The purpose of this study is to assess the clinical performance of an investigational contact lens over 30 days of daily wear.
This work aims at the analysis of ocular aberrations induced by wave front optimized ablation profiles WFO using I-Trace aberrometer (Ray -Tracing)
To observe the retinal microvascular alteration during 3 months follow-up after Implantable Collamer Lens (ICL) operation in moderate and high myopia patients using quantitative optical coherence tomography angiography (OCTA) analysis.
The aim of this study was to test the hypothesis that OCT-guided 110 µm targeted flaps will result in accurate, predictable, and precise thickness flaps, with low complication rates when performed and compared using both 2D and 3D flap geometry applications and how it correlated to visual experience and quality of life responses during the early postoperative period.
