EYEBALL PRESERVATION LIQUID FOR KERATOPLASY

摘要

PURPOSE:To obtain an eyeball preservation liquid for keratoplasy, by adding sodium chondroitinsulfate which is a biocomponent having higher colloid-forming capability than dextran. CONSTITUTION:The objective eyeball preservation liquid for keratoplasy can be produced by dissolving NaCl, KCl, CaCl2.2H2O and MgSO4.7H2O in purified sterilized water at room temperature - 60 deg.C, successively dissolving glucose, sodium citrate dihydrate, sodium chondroitinsulfate, NaH2PO4 and Na2HPO4.12 H2O into the above solution and sterilizing the product. Preferably, the sodium chondroitinsulfate has a molecular weight of 20,000-60,000, preferably 40,000-60,000 and its concentration in the liquid is 0.5-3.0w/v%, preferably 1.0-2.0w/v%. The liquid is preferably adjusted to have an osmotic pressure of 270-350mOsM.
