CIBA's website says:
"CIBA Vision is working to increase available supply of the lens care
products most in demand by consumers (and eye care professionals).
Because of this, we are not currently shipping SoftWear Saline. We
expect to resume shipments of this product to retail stores and eye
care professionals later in the year, and apologize for any
inconvenience that this supply interruption may cause. If you are a
current user of SoftWear Saline, contact your eye care professional to
see if AQuify® Multi-Purpose Solution would be suitable for your
particular needs."
