The Practice
Dr. Mahanti’s first priority is delivering the highest quality eye care to the population of Flagstaff and its surrounding communities. While having special training and expertise in refractive surgery (procedures to reduce dependence on glasses and contact lenses), he provides a wide range of services. Outpatient cataract and other eye surgery are provided by an on-site facility with state-of-the-art equipment. Diabetic and glaucoma lasers can be performed on-site. Routine and emergency care are provided on a daily basis. Visiting subspecialists regularly use the office to assist with difficult eye problems.
Dr. Mahanti is on active staff at Flagstaff Medical Center and helps with trauma, medical eye consults and emergencies. He has an excellent rapport with other physicians in the Flagstaff community and regularly works with them in helping patients with their eye and vision problems. He is proud and humbled that many of our local physicians and their family members have chosen him for their eye surgery.
