The purpose of this study is to compare lens characteristics and comfort between an experimental contact lens and a marketed contact lens.
The purpose of this study is to compare the clinical performance of three silicone hydrogel contact lenses over a 2 week period.
This study will assess the ophthalmic compatibility of three different silicone hydrogel lenses worn on an overnight basis for six nights by adapted daily soft contact lens wearers.
This trial will aim to assess lotrafilcon A lenses, in terms of comfort and symptoms, that include the following upgrades: the addition of Copolymer 845 (Co845) as a conditioning packaging...
This trial will aim to assess lotrafilcon A lenses that include the following upgrades: the addition of Copolymer 845 (Co845) as a conditioning packaging saline additive, an inversion mark...
With the increasing prevalence in myopia there is growing interest in active myopia prevention. This study aims to increase our understanding of parental attitudes to myopia development and control, a...
During the past 30 years, the prevalence rate of myopia has been increased dramatically. Myopia has become one of the leading causes of vision loss in some countries, whereas the mechanism of the main...
The purpose of this study was to determine the prevalence of myopia in a population of children in Sweden. Retrospective analysis of children in a region in Sweden referred to eye care from the nation...
High myopia and pathologic myopia are common causes of visual morbidity. Myopic pathology can affect all regions of the retina, though there is currently no classification system to distinguish anteri...
Myopia progression is thought to involve biomechanical weakening of the sclera, which leads to irreversible deformations and axial elongation of the eye. Scleral crosslinking has been proposed as a po...
Excessive axial myopia associated with complications (especially posterior staphyloma and CHOROIDAL NEOVASCULARIZATION) that can lead to BLINDNESS.
A projective test used to evaluate a broad range of personality variables including pathology of thought and perception. The subject's responses to inkblot prints are scored along with subjective interpretation by the test administrator.
A test to determine the lowest sound intensity level at which fifty percent or more of the spondaic test words (words of two syllables having equal stress) are repeated correctly.
Tests of accuracy in pronouncing speech sounds, e.g., Iowa Pressure Articulation Test, Deep Test of Articulation, Templin-Darley Tests of Articulation, Goldman-Fristoe Test of Articulation, Screening Speech Articulation Test, Arizona Articulation Proficiency Scale.
Method of measuring the bactericidal activity contained in a patient's serum as a result of antimicrobial therapy. It is used to monitor the therapy in BACTERIAL ENDOCARDITIS; OSTEOMYELITIS and other serious bacterial infections. As commonly performed, the test is a variation of the broth dilution test. This test needs to be distinguished from testing of the naturally occurring BLOOD BACTERICIDAL ACTIVITY.
