Udon Thani. I have my eyes checked every three months by the Government Hospital Doctor who has in addition a private practice which I attend. Eighteen months ago he carried out, at his clinic, a cataract operation on my right eye . Cost 25,000 baht. He has been looking after my eyes for a number of years, controlling glaucoma and ensuring consistently good eye pressure and 20/20 distance viewing. I am 84 by the way. Please contact me if you would like to discuss this further.
