Patients often ask me if there are differences between brand name and generic contact lens solutions.  They are concerned about price and wonder if the brand name solutions are really worth the extra expense.  The answer is YES!  Dr. Gary Andrasko is noted for his continued research regarding the biocompatibility of contact solutions with various contact lens products.  He measures the amount of corneal cell disruptions caused by both brand name and generic solutions.  The greater the amount of corneal irritation, the greater the likelihood of discomfort with contact lens wear and the potential for contact lens related red eye.  The cornea has a similar structure to our skin and the more wear a solution causes on a contact lens, the more irritated the cornea becomes.  You can find the results of Dr. Andrasko's most recent research at, http://www.staininggrid.com/faq.aspx.  Just find the brand of contact lens you are wearing and match it to the solution you are using.  The lower the staining percentage, the better compatibility between the two products.  Dr. P
