Attending all of your follow-up appointments and paying close attention to your surgeon's instructions are the best ways to reduce the risks of any type of refractive surgery, including a custom lens replacement. Using the eye drops recommended by your surgeon to prevent dry eye and keep your recovering eyes lubricated will be one of those guidelines. You'll be shown which eye drops to use by your doctor. Antibiotic eye drops help with healing, prevent infection, and make the recovery process more comfortable for you.
