Aestheticians are not licensed to practice medicine. I am sure you understand that now. I am not an expert in the Arizona business and professions codes but I see no where to indicate that an aesthetician can inject BOTOX and Fillers. The Arizona medical board does permit unlicensed medical assistants to do injections and it is possible that some sharp operator may try to justify the illegal, unlicensed practice of medicine using this angle. However, the law is clear that such individuals need to be under the direct supervision of a licensed physician. Direct supervision means that the physician examined you and is in the office and immediately available. However, it is cerainly possible that the Arizona Medical Board may interpret the injection of these agents as outside the scope of what the law authorizes a medical assistant to do even under the direct supervision of a physician.
The Arizona Medical Board (http://www.azmd.gov/) has some very practical documents that can help you evaluate a potential cosmetic surgeon:
Also this site has information on how to file a complaint with the Arizona Medical Board. I assure you that they will investigate your complaint if your file a report. Many spas operate because state medical boards lack the resources to find and close down all of the illegal clinic and spa situations out there. This treatment almost caused you to go blind from corneal ulcers. Taking action to report this individual may very well save someone else.
Could you develop corneal ulcers after a treatment like you describe, absolutely. Please do not get treatment in a salon again (I am sure I don't need to tell you that.) Stick with a core physician: General plastic surgery, dermatology, facial plastic surgery, and oculoplastic surgery. I recommend you see a good cosmetic dermatologist to see if the lumps you are describing can be dissolved with hyaluronidase. Don't be surprised if it turns out that you were not treated with Restylane. Sometimes these dishonest practices use illegal fillers like silicone oil which is much cheaper than a legal filler like Restylane. There are truly excellent, highly ethical physicians in Arizona who can help you. I can recommend Miriam Cummings, M.D. in Scottsdale, a well regarded cosmetic dermatologist.
