Resumen
In this work we determined the pH of three hydrogen peroxide systems (two steps systems), and we studied the pH time evolution of these systems. The study were carried out over a 32 days periodo The pH of the solutions was measured using a micropH 2002 erison pH-meter. The pH of the disinfection solution was measured immediately at the beginning of ttíe disinfection cycle and for the neutralization solution was measured at the end of the neutralization cycle for each system. The pH of the disinfection solutions ranged from 3.22 to 3.90 pH units and the pH of the neutralization solution ranged from 7.01 to 7.32 pH units. AII the neutralization solutions tested presented pH values within the ocular comfort range during the testing period but these values were not close to the tear's pH.
