Biomicroscopy of papillae associated with wearing of soft contact lenses.
We studied the topographical, macrostructural, and fluorescein staining characteristics of papillary changes of the upper tarsal conjunctiva associated with the wearing of hydrophilic (soft) contact lenses. Fifty soft contact lens wearers with elevated conjunctival papillae greater than 0.3 mm in diameter were studied. Topographic characteristics recorded were distribution and number of papilla...
متن کاملThe impact of wearing single vision soft contact lenses on the peripheral refractive error
The purpose of this study was to determine the changes in the relative Aim: peripheral refractive error produced by soft single vision contact lenses in myopic schoolchildren. 27 myopic schoolchildren aged between 13 to 15 years were Methods: included in this study. The measurements of central and peripheral refraction were made only on the right eye using a Grand-Seiko WR-5100K open-field auto...
متن کاملOn-eye performance of custom wavefront-guided soft contact lenses in a habitual soft lens-wearing keratoconic patient.
PURPOSE To assess visual, optical, and fitting characteristics for wavefront-guided soft contact lenses produced for one habitual soft lens-wearing moderate keratoconic eye. METHODS A process for production and evaluation of custom wavefront-guided soft contact lenses was developed. Wavefront aberrations were quantified with the COAS-HD wavefront sensor (Wavefront Sciences); soft contact lens...
متن کاملSoft contact lenses in cases of aphakia.
The use of hydrophilic acrylates (POIYHEMA) in the composition of contact lenses was first described by Wichterle and Lim (I960). The development of a spun cast lens has taken several years. The basic technique by Wichterle has now been extended by the manufacturers, Bausch and Lomb. Whilst the low minus powers are available in more than one back curve fitting, the high minus and aphakic series...
