Multi-step systems entail the use of at least a daily cleaner, a disinfectant, and a weekly enzyme cleaner. Multi-step systems differ from multi-purpose solutions in that the user typically uses three different products versus an all-in-one product.
Multi-step systems share many of the disadvantages of multi-purpose solutions. Daily cleaning solutions generally contain many different chemicals and preservatives. Enzymatic cleaners are an effective way to remove protein buildup, however once the enzyme cleaner is dissolved in a saline solution, lenses must soak in the solution for up to 8 hours to achieve optimal results.
After cleaning, disinfection of soft contact lenses is required. Disinfection options for multi-step system users include thermal or chemical means.
Because of the increased number of products, multi-step systems are usually less convenient and much more expensive than other cleaning and disinfecting options.
If you use a multi-step system to clean and disinfect your lenses and you are interested in saving both time and money, while taking proper care of your lenses, you should contact an eye care specialist to see if the PuriLens System is right for you.
