Ethnic differences in dry eye symptoms: effects of corneal staining and length of contact lens wear.
PURPOSE To explore the relationships among length of contact lens (CL) wear, degree of corneal staining and severity of dryness symptoms, and to determine whether these relationships differ between Asians and non-Asians. METHODS Adapted soft CL wearers (n=395; 180 Asian, 215 non-Asian) were required to discontinue CL wear for at least 24h and report to the University of California, Berkeley C...

Materials and Methods. This was a prospective and comparative study in which 31 myopic subjects were fitted with the same Si-Hy CL and 23 underwent OK treatment for 3 months. Dry eye questionnair...
متن کاملCorneal response to rigid contact lens wear.
Three adult rhesus monkeys were subjected to 2 and 24 hours of polymethylmethacrylate (PMMA) contact lens wear. The induced corneal changes were examined with the electron microscope. Mild epithelial oedema as well as early degenerative cell changes was present already after 2 hours' wear. Rigid lens wear for 24 hours produced more severe oedema and cell alterations together with premature cell...
متن کاملLower volumes of tear menisci in contact lens wearers with dry eye symptoms.
PURPOSE To investigate tear meniscus volumes during short-term lens wear by soft contact lens (SCL) wearers with dryness symptoms. METHODS Three groups of 20 subjects were recruited. Group 1 consisted of SCL wearers with self-reported dryness. Group 2 consisted of asymptomatic wearers. Group 3 was composed of asymptomatic non-lens wearers. Contact lenses were fitted on each eye, and both uppe...
متن کاملLid-wiper epitheliopathy and dry-eye symptoms in contact lens wearers.
PURPOSE To evaluate whether dry-eye symptoms are associated with epitheliopathy of that portion of the upper eyelid marginal conjunctiva-the lid wiper-that wipes the ocular, or contact lens surface, during blinking. METHODS Subjects were divided into two groups based on the presence or absence of dry-eye symptoms. The lid wiper of asymptomatic (n=75) and symptomatic (n=30) soft contact lens w...
