In-Depth Information
synthetic block copolymer that improves the hydrophilic properties of SH
lenses. It also has an extremely high affi nity for the hydrophobic areas of
all soft CLs that are not wetted by the tear fi lm.
CONCLUSIONS
CLRDE is the most important cause of CLs dropout with a signifi cant
economic impact on the CLs market. For this reason, it is important for
the ECPs to know the interaction of CLs wear on tear fi lm as well as the
characteristics of CLs products in the market that are useful to minimize
CLRDE effects.
