Unisol 4 Discontinued; Your Best Replacement Options11:03 AM
In fall 2015 Alcon very quietly discontinued their preservative free saline solution for contact lens rinsing and filling, the well-regarded Unisol 4. Most local pharmacies and box stores are now out of the product, and patients that have used the product loyally for years are scrambling for a replacement. If you don't think the panic is real, just check out the price gauging on ebay -- $50 for a 3 pack that would have run you under $10 just a few months ago. I've spoken with a rep from Alcon, and there was no official statement released as to why the product was discontinued, and there is no plan for reinstating the product in future. If you are in need of preservative free saline, here are a few doctor recommended solutions that can take it's place.
CLEAR CARE Rinse and Go: Alcon launched this "replacement" for Unisol in spring 2016, made specifically for rinsing contact lenses. It is a preserved saline so it is fine for rinsing, but not suitable for filling contact lenses.
The Purilens Plus Ultra PF saline mentioned above is also preservative free, so it could be used to fill contact lenses as well as rinse them. I strongly prefer the preservative and buffer free vials mentioned above, but if for some reason those aren't working well for you, the Purilens Plus is the most similar thing to Unisol on the market today.
