Patterns of mucin adherence to contact lenses.
PURPOSE Contact lens wear alters the preocular fluid through factors that include tear deposits on the lens. In the current study, lens-adherent material was extracted to assess whether contact lenses sample mucins from the preocular fluid. METHODS Discarded extended-wear contact lenses were collected from patients with no ocular surface disease. Mucins were extracted in guanidine hydrochlori...
متن کاملLipopolysaccharide in adherence of Pseudomonas aeruginosa to the cornea and contact lenses.
PURPOSE To determine the role of smooth or rough lipopolysaccharide on adherence of Pseudomonas aeruginosa bacteria to the rat cornea in vitro and on contact lenses of differing types. METHODS Adherence of a smooth (AK957) and isogenic rough strain (AK1012) of P. aeruginosa bacteria to rat corneas that were either normal, traumatized using a 20-gauge needle or treated for 15 min with 0.1N sod...
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...
متن کاملDrug delivery through soft contact lenses.
Clinical studies were conducted on 466 patients waiting for senile cataract surgery and receiving chloromycetin, gentamicin, or carbenicillin subconjunctivally and through New Sauflon 70 and New Sauflon 85 lenses. The aqueous drug levels were biologically estimated at various time intervals. Soft contact lenses provided significantly higher drug penetration than subconjunctival therapy. Both mo...
