Selecting an appropriate hydrogel lens care system.

The selection of the appropriate hydrogel lens care system must incorporate an understanding of the properties and actions of cleaning, disinfecting and rinsing solutions; the characteristics of the lens; and the ocular characteristics of the patient. When changes in a care system are required, reselection involves recognizing: the nature of adverse ocular responses; the nature of deposits; any changes in patient characteristics; the characteristics of potential new products. These factors are considered and used to create an approach to selecting the initial care system and to reselecting an alternate care system.
