Looking for A Replacement for Unisol 4 PF Saline?

Although we do not fit for scleral lenses at Dedham Ophthalmic Consultants, we felt this information would be useful for those who currently wear them. 

Alcon stopped producing and distributing Unisol 4 but the good news is, there are solutions!

Addipaks sterile saline vials

Addipaks are preservative free simple sodium chloride 0.9% and water solution in single 3ml or 5ml vials. At Dedham Ophthalmic Consultants, we recommend 0.9% sodium chloride solution, for “off-label” use to rinse and fill your scleral lenses. Because scleral lenses are a relatively new phenomenon, and also a niche concept, the market has not yet caught up in terms of providing products with FDA sanctioned labeling for that specific use. Therefore, they may not be covered by health insurance, as their use with prosthetic devices is considered “off-label”.

There are some limitations to Addipak Sterile Saline Vials

  • Not large enough for those who use a lot in lens rinsing/filling
  • Unbuffered saline, not tolerated equally well by all users
  • Not labeled for ocular use

Other highlights of Addipak Sterile Saline Vials Include:

  • Non-Pyrogenic
  • Not for parental administration
  • No bacteriostatic agent or other preservative added

Another option to Unisol 4 is Purilens Plus.

Purilens Plus is a chemical and preservative-free contact lens cleaning solution exclusively formulated for use with the PuriLens Plus Soft Contact Lens Cleaning/Disinfecting System. It is a sterile preservative-free saline solution buffered with boric acid and sodium borate. Purilens can also be used as an alternative to Unisol in the rinsing and filling of the prosthetic devices used in scleral lens treatment.

PLEASE NOTE: Purilens is NOT a standalone cleaner or disinfection solution; it does not substitute for nightly cleaning and disinfection.

PuriLens Plus solution can be ordered directly from Purilens at www.purilens.com.

Do not hesitate to email a Dedham Ophthalmic Consultants technician by using our contact form, with any further questions or concerns; and please let us know right away if you notice any irritation caused by your new products.
