back in 2011 i had a detached retina, and bangkok hospital rayong wanted 160,000thb for the op to be done at BH Pattaya, which was to take place 4 days later, my stepson arranged for a doctor at rama hospital Bangkok to see me so a drive to bangkok was required, this doctor said she could do the op the next day at EENT https://eent.co.th/ hospital Bangkok, a laser was used to repair the tear and the eye was filled with gas, so as Transam posted above 2 weeks of laying face down, the gas eventually turns into eye fluid, total cost yes i know it was in 2011 was 80,000thb as apposed to BH Rayong price of 160,000thb picked up by travel insurance from the UK, operation carried while awake and aware of what was going on, 12 years on eye is still good, i highly recommend her https://www.bumrungrad.com/en/doctors/Somsiri-Sukavatcharin, i know the op was looking at the N East area , posted for information of the op.
