Dry eyes drops, must they be preservative free?

Postby Shivan82 » Sun Oct 08, 2006 7:18 pm

I had my PRK op done 5 days ago, and was instructed to use preservative free, single-use packaged eye drops. This gets insanely expensive if I must dose every half hour or so. Is Systane ok to use post-PRK, long-term even though it contains preservatives?

Another thing, why did they only give me nimesulide for pain after the surgery? Thank[fully] I had Zyrem and Xan*x at home so I was able to at least pass out some of the time during the 4 days of excruciating pain that followed the surgery. Is there a medical reason for not prescribing opiate painkillers after the surgery, or is it simply the doc's preference?

The preservatives used in artificial tears are a toxin. Toxins generally do not promote healing. You should use only preservative-free artificial tears until your doctor instructs otherwise.

A variety of pain killers are used for postoperative pain consistent with PRK, LASEK, or Epi-Lasik. There may be a medical reason to not prescribe eye drop pain killers, but meds takin orally would normally be okay. You need to ask this question of your doctor.
