Artificial tears: active ingredient %

2022-07-14 23:33:27
Hello, I underwent LASIK two weeks ago and my doctor recommends using artificial tears daily including Carboxymethyl cellulose preservative-free but I've seen two types Carboxymethyl cellulose 0.5% (liquid drops) and another one 1% (gel drops) . . What's the difference between the two percentages? Which is better? particularly right before sleeping (that would last longer) Thanks

Gel drops will be better.
