Ophthalmic composition that is an aqueous composition that has a pH between 7 and 7.4, osmolarity between 280 and 300 mOsm / l, and that comprises one or more glycosaminoglycans (GAG) in amounts ranging between 0.1 and 5% w / w, poly (vinyl alcohol) (PVA) in a concentration between 0.1 and 0.5% w / w, glycerol in amounts ranging between 0.5 and 1% w / w, chloride of sodium between 0.01 and 1% w / w, disodium phosphate between 0.1 and 1% w / w, in which said composition has a contact angle measured on a Kapton surface in the range of 50º to 80º, in which said contact angle is measured as a static contact angle by means of the sessile drop method with the Contact Angle System OCAE15 instrument, in which the drop has a volume of 3 ml and the rate of deposition is 1 ml / s, where the measurement time after droplet deposition is 50 seconds. |
