regular eyedrops VS non-preserved eyedrops
In the previous article, preservative-free eye dropper is recommended for user. Then let’s see what we found in the study.
?A study in users of regular eyedrops found that:
42% patients reported sensation of a foreign body.
48% reported pain or discomfort on?instillation.
35% reported eye dryness
?
However, in the users of non-preserved eyedrops found that:
Only 15% of patients report sensation of a foreign body.
Only 19% of patients report pain or discomfort on instillation.
Only 16% of patients report eye dryness
?
So how are non-preserved eyedrops better?
1.?Better tolerance
2.?Better treatment compliance
3.?Better surgical prognosis
4.?But more important is about the special design of the packaging can ensure that bacteria does not have the chance to settle inside it.?
