He helped several excimer laser manufacturers obtain FDA approvals for their lasers in the United States. He holds the record for many firsts. He was the first doctor in California to perform LASIK surgery and was the first to perform Custom Wavefront Guided LASIK. He was also the first to use the FemtoSecond Laser (IntraLase FS30 – All Laser LASIK), which is safer and more precise than a traditional blade and also increases the patient’s chances of achieving 20/20 or better vision.  He was the first in California to use the Ziemer FEMTO LDV™ Crystal Line laser, currently the most advanced laser available for LASIK surgery.

He completed his fellowship in Corneal Surgery and External Disease at the Emory University Department of Ophthalmology in Atlanta, Georgia. He has been board certified in ophthalmology for more than 25 years.

Dr. Tooma has done medical teaching missions to Romania, Bulgaria, China and Fiji, helping teach local ophthalmology doctors about LASIK procedures. In 2008, he and his wife, Maria Tooma DDS, founded the Mission at Natuvu Creek in Fiji.

James Pereyra, Vice President of Business Development

As vice president of business development for NVISION, James Pereyra’s mission is to form new opportunities for the company, including mergers and acquisitions and relationships with large accounts. “I work with corporations, referral networks, hospital systems and insurance companies,” he says.  “I cultivate relationships to not just build business, but to build the right kind of business.”

Having done mergers and acquisitions from “both sides of the table,” James says that integration is always the biggest objective, specifically ensuring that the employees of the acquired company feel like they have a new home and are assimilated into the processes. Cultivating a sense of belonging is the key to a successful merger.

James is genuinely interested in people and their stories and relies on his natural curiosity and intuition to understand what people need when doing business with NVISION.  Being successful in new business requires sensitivity, empathy, and emotional intelligence – all gifts that James demonstrates on a daily basis.

Originally from Texas, James moved to Orange County in his teens and has lived in California most of his life. He and his wife travel the world and have the goal of visiting every country. But despite his wanderlust, James is a homebody and at the end of every trip, he relishes coming home to his two Chihuahuas.

James knows that cultivating symbiotic relationships is key to strategic growth. “Business development is the successful marriage of analytics and humanity,” he says. “The personal side of the business helps ensure the success of the financial side. Without both you cannot unlock the true value of acquisitions.”
