Inspiration for TRSC

TRSC International LASIK Center was founded in 1997 by Dr.Ekktet Chansue (Medical Director) and Wanida Chansue as the first private medical center in Thailand that specializes in visual correction. Wanida Chansue was one of first patients to undergo PRK surgery. Her experience of regaining good vision, along with her hospitality and nursing background, became her inspiration in founding TRSC.  


The pioneer era


1997 TRSC, The First Private LASIK Center in Thailand

Dr. Ekktet Chansue and Mrs. Wanida Chansue founded TRSC as the first private LASIK center in Thailand at Thai Wah Building with only 6 staff members. With the determination to raise the standard of the refractive surgery to new levels, TRSC’s vision was to combine exceptional medical standards with excellent service.

TRSC’s exclusive Patient Data System (PDS)
Dr. Ekktet Chansue and his team of programmers designed an online patient information management system to record and analyze all measurement results in order to obtain the most accurate and up-to-date information.

Technolas K217 Excimer Laser
Dr. Ekktet Chansue introduced Asia’s fi1st Technolas K217 Excimer Laser by Bausch and Lomb, then the most advanced excimer laser with capabilities to treat both myopia and astigmatism.  Using less time during operation, this technology also enabled faster vision recovery and highly accurate results.


In 2000, Thailand‘s first Technolas 217 Zyoptix Excimer Laser was introduced. Its innovations included the Flying Spot system, which allowed treatment plans to be customized according to each patient’s eye shape, and an eye tracking system with the fastest response time, to ensure an accurate treatment in the case of eye movement during surgery.


The era of Growth and Development

To ensure the highest quality service at all times, we moved to the 6th floor of the U Chu Liang building, an area four times as large and TRSC was renamed as “TRSC International LASIK Center”

Data of 2022

* Uncorrected visual acuity (UCVA) is defined as visual acuity measured without correcting refractive errors.

  • If you have 20/16 vision, you can see things at 20 feet that people with normal 20/20 vision can see at 16 feet. This means you have vision that is better than 20/20.

  • 20/20 vision is normal vision acuity (the clarity or sharpness of vision) measured at a distance of 20 feet. If you have 20/20 vision, you can see clearly at 20 feet what should normally be seen at a distance.

  • Having 20/40 vision means that when you are standing 20 feet away from an object, you can see it just as clearly as a person with normal (20/20) vision can see an object that’s 40 feet away. You need to meet these requirements of 20/40 or better to get a standard driver’s license.
