Filter by:The purpose of this study is to verify the compatibility of a silicone hydrogel lens when used with four multipurpose disinfecting solutions (OPTI-FREE® RepleniSH®, ReNu MultiPlus®, Solo-Care Aqua™ and MeniCareTM Soft).
The purpose of the study is to evaluate and compare, on a daily wear basis, the performance of two contact lens care solutions when used with silicone hydrogel soft contact lenses with regards to comfort and dryness symptoms.
The purpose of this study is to determine whether a new non-contact biometer, is as accurate as the the available gold-standard.
Purpose: To determine whether the use of reading glasses blocks the near work mediated increased incidence of myopia in healthy school children. Methods: SMART enrolled 115 emmetropic children (ages 7-9 years). The children were recruited in the Principality of Liechtenstein. They were randomly assigned to either the control group (n=52) or to receive reading glasses with a lens power of +2.0 dioptres (n=63). The primary outcome measure was progression towards myopia as determined by autorefraction after cycloplegia. The secondary outcome measure was change in biometry measurements of corneal curvature, axial length, anterior chamber depth, crystalline lens thickness, and vitreous chamber depth using partial coherence interferometry.
To evaluate the safety, efficacy and physiological performance of daily disposable spherical and toric soft contact lenses in a vision-corrected population of children ages 8-11 years of age. To evaluate the ability of the practitioner to fit these lenses and for the children to wear and manage these lenses.
This study was designed to compare the difference of using atropine eyedrops alone from atropine combined with the stimulation of auricular acupoints therapy in reducing myopia progression.
The primary objective of this study is to compare subjective symptoms and ocular health in a group of individuals who are currently wearing soft contact lenses on a daily wear basis, after a short period of no lens wear and during the time course when using differing care regimens.
The primary purpose of this study is to investigate the clinical performance of a new silicone hydrogel contact lens over a period of 6 months of extended wear.
The purpose of this study is to conduct a prospective assessment of small target contrast sensitivity and disability glare in refractive surgery. Study subjects will undergo the treatment of their choice (PRK or LASIK) and will be evaluated before and after treatment. Evaluations will include best corrected visual acuity, uncorrected visual acuity, psychometric questionnaire, pupil size, biomicroscopic examination, manifest refraction, wavefront measurements, low contrast acuity, and contrast sensitivity at normal and at low luminance with and without disability glare.
The objective of this study is to conduct a prospective clinical trial to evaluate the safety and efficacy fo the VISX Excimer Laser system for the treatment of naturally occurring low to moderate myopia, with or without low levels of astigmatism, in U.S. Army personnel.
