Both are FDA-approved as safe and effective. EVO can be a better option for patients than contacts for a variety of reasons including efficiency, cost, and convenience. In terms of costs, on average, contact lenses cost $12,000 over a lifetime. (Your personal cost will vary). Because EVO is a long-term solution, your procedure costs are generally fixed to a one-time fee. When you compare with the long-term costs of contact lenses, EVO typically pays for itself. Finally, EVO lenses can free contacts and glasses wearers from the daily inconvenience and maintenance associated with contacts and glasses.
