Filter by:The purpose of this study was to evaluate overall satisfaction with AIR OPTIX® COLORS as compared to FRESHLOOK® COLORBLENDS contact lenses.
To assess whether Chinese ocular exercise is effective in altering distant and near visual acuity, ocular accommodation and visual symptoms in myopic teenager, and thus might have the possibility of slowing myopia progression in teenager through a weak but long-term effect.
Evaluate visual outcomes and contrast sensitivity for subjects undergoing bilateral myopic LASIK procedure using the 200 kHz WaveLight® FS200 Femtosecond Laser and the WaveLight® Allegretto Wave® Eye-Q Laser. The use of advanced technology may decrease the loss of contrast sensitivity and improvement of postoperative visual acuity results.
This study is to evaluate the performance of the LSH (mangofilcon A) silicone hydrogel soft contact lenses when used as a daily wear contact lens for the correction of myopia.
The purpose of this study is to determine whether a new type of soft contact lens with a unique optical design (dual focus) is effective at slowing the progression of myopia (near-sightedness) in children.
The purpose of this protocol is to determine wether the initial protocol in the treatment of subfoveal choroidal neovascularization associated to High Myopia with bevacizumab intravitreal injections is more effective when using 3 doses vs using 1 single dose in the load period
The purpose of this study is to compare the subjective performance for handling of two daily disposable contact lenses, stenfilcon A and etafilcon A.
Phase I: Focus groups on different designs of adjustable glasses and standard glasses (August-September 2012) Phase II: Two-month randomized trial comparing four groups: (September 2012 - August 2013)
Over 1 million people in the UK suffer from untreatable visual impairment, many of them elderly. The major complaint of visually impaired people is their inability to carry out simple tasks, especially those involving reading. It is known that this activity limitation is a major cause of depression in an older population, and it is reflected in reduced quality of life. Low vision clinics, mostly based within hospital ophthalmology departments, dispense optical magnifiers to allow patients to carry out these tasks again, but these devices do have limitations (unusual posture, short working distance, monocular viewing). Although electronic magnifiers have been around since the 1960s, they were initially very large and expensive. Recent advances in technology have brought about an explosion in the number and range of portable and moderately-priced aids, which can be used binocularly, in a natural working position: these are currently not available through the NHS. Evidence is needed as to whether these portable hand-held electronic magnifiers could offer a significant benefit to the majority of patients, and therefore whether they should be routinely dispensed in low vision clinics. The proposed study is a two-arm randomised crossover trial with existing users of optical magnifiers being assigned to use a hand-held electronic magnifier in addition to their existing devices for 2 months. Reading and task performance will be measured with the aid, and compared to the performance with optical aids, and the patient will be asked to report on the comparisons between the aids.
The purpose of this study is to evaluate the lipid uptake, wetting characteristics, and visual performance of AIR OPTIX® AQUA and ACUVUE® OASYS® with HYDRACLEAR® contact lenses when used in conjunction with two contact lens care systems.
