What your patient might ask you…

Are daily contacts healthier than reusable contacts?

Still yes.
A new study was just published in Cornea examining daily vs. reusable contacts and their effect on the ocular surface.

Tell me about the study.
The authors divided patients into three groups and had them wear one of three different type of contacts:
1. Daily disposable hydrogel contacts (22 people).
2. Daily disposable silicone hydrogel contacts (25 people).
3. Reusable silicone hydrogel contacts (24 people).

What did they measure?
They performed tear function tests and measured proinflammatory cytokine levels before contact lens wear and at 1 and 3 months after using contacts.

What did they find?
1. Less proinflammatory cytokines in the tears of daily contact lens wearers as compared to reusable lens wearers. The lowest level was in the daily hydrogel wearers.
2.  Compared to the pre-contact lens wearing baseline testing, there was an increase in proinflammatory cytokines in all groups.

The take home:
Per the authors, “daily disposable CLs can be considered to cause less damage to the ocular surface and less increase in proinflammatory cytokine levels.”
