Dr. Tran

Blending a rich background in engineering with profound medical expertise, Dr. Dan B. Tran has become a pivotal figure in vision correction technology since 1999. His pioneering use of the first commercially available IntraLase femtosecond laser for LASIK in the United States has set new benchmarks for safety and precision in the field, establishing techniques now standard in laser vision correction.

His approach combines IntraLase with Custom LASIK, offering personalized treatments that have significantly enhanced the likelihood of achieving 20/20 vision or better. This meticulous combination is approved by NASA and the Department of Defense for U.S. Service personnel, highlighting its effectiveness.

Further extending his innovative impact, Dr. Tran was the first in the world to integrate IntraLase technology with intracorneal rings (Intacs™) to treat keratoconus, offering new hope to young adults facing this vision-impairing disorder. Beyond LASIK, he excels in using cutting-edge technology for correcting near vision and presbyopia, providing alternatives for those over 40 and performing advanced cataract surgeries. His real-time surgical adjustments ensure optimized outcomes, setting him apart in the field.

In 1999, Coastal Vision Medical Group earned the distinction of becoming the official LASIK provider for both the Long Beach Police Department and the San Bernardino Sheriff’s Department. Esteemed by eye doctors, physicians, and high-level executives for his surgical skills, Dr. Tran is the surgeon of choice among industry insiders.

For Dr. Tran, the greatest reward comes from restoring vision for his patients, witnessing firsthand the transformative impact on their lives. His ongoing commitment to innovation and excellence continues to lead the way in providing superior eye care.
