An objective, digital-imaging method of measuring corneal staining was evaluated in 24 subjects wearing soft contact lenses. The method was used to compare the clinical performance of common multipurpose care systems (MPS) for soft contact lens care. Subjects used three different MPS, one containing polyquaternium-1 (PQ) and two containing polyhexanide (PX1(More)
PURPOSE To evaluate factors affecting corneoscleral profile (CSP) using anterior segment optical coherence tomography (AS-OCT) in combination with conventional videokeratoscopy. METHODS OCT DATA WERE COLLECTED FROM 204 SUBJECTS OF MEAN AGE 34.9 YEARS (SD: ±15.2 years, range 18-65) using the Zeiss Visante AS-OCT and Medmont M300 corneal topographer.(More)
Patients with acute leukaemia or undergoing allogenic bone marrow transplantation at University College London Hospital Trust were screened for the presence of aspergillosis by polymerase chain reaction (PCR). Aspergillus DNA, from whole blood samples, was amplified by nested PCR to detect a 135 bp fragment in the mitochondrial region of Aspergillus(More)
BACKGROUND Allegations that exposure to endogenous silicone, especially related to breast implants, might be causally related to connective tissue disease originated from case studies. More recent comparative studies have implied no such increased risk. The aims of the present study were to compare the prevalence and/or incidence of autoimmune and(More)
PURPOSE To determine the first-year retention rate for patients fitted with contact lenses (CLs) and identify factors associated with retention and dropout. METHODS This multi-site study was a retrospective chart review of the status of neophyte CL wearers fitted in representative UK eye care practices. RESULTS Consecutive records for 524 patients at 29(More)
PURPOSE To determine which ocular topography variables affect soft contact lens fit. METHODS Fifty subjects each wore three pairs of soft lenses in random succession (Vistakon Acuvue 2, Vistakon Acuvue Advance, Ciba Vision Night & Day), and various aspects of lens fit were evaluated. The steeper base curves of each type were worn in one eye and the(More)
