I know this is an old thread but since it didn’t get much response I will post my current situation just in casr there are some folks wondering about cataract surgery. I don’t live in Udon anymore so my experience is in Ubon Ratchathani, but should be typical of what you will find in Udon. Bottom line is I am now scheduled for cataract surgery on April 7. Total cost wil be 23,000 baht inclusive at a private clinic in Ubon.
The technical term is Phacoemulsification with Intraocular Lens Implantation. In layman’s terms, they make a tiny incision in your lens, stick some sort of device in there which dissolves the lens, then extract the now emulsified lens.

You can google those terms to read more than you care to know about the procedure. Now I realize that this sounds like some North Korean torture practice to extract information, but trust me it’s not as horrible as it sounds. Then they insert a folded up acrylic lens through the incision and it unfurls somehow, then they stitch up the incision and voila, you’ve got a new lens, which should never need correction. I had it done about six years ago in the States on my right eye and it was a piece of cake. Took about 20 minutes, I didn’t feel a thing as I was awake during the procedure but somewhat groggy. It was done as an outpatient in a clinic and I went home immediately after with a black eye patch on the eye. The next day I went back and they took out the stitches and gave me those horrible dark glasses that you see old people walking around in and looking ridiculous. But hey, I’m an old person too so what the Hell. After a few days I had perfect vision in the right eye. It was a revelation to see how bright and clear everything was. When I first went into Wal-Mart I couldn’t believe all the bright colors whereas for years I had been seeing dingy blurry colors, and I didn’t need glasses which I had worn since high school, except for reading.
So back to the present. My eyesight in my left eye has been getting progressively worse so that I am now legally blind in my left eye, although I can still see distances without glasses. However I have no 3D vision which makes it hard to go down long flights of stairs or to navigate the uneven sidewalks so prevalent in LOS. So I went to our local hospital here in Amnat Charoen and they do this operation routinely, but only once a week and they have a FIVE MONTH waiting list!. There must be an epidemic of cataracts in Issan. The ophthalmologist recommended a private clinic in Ubon that could do it faster, and my wife found out that a nurse friend of hers had just had her Father done at that clinic and highly recommended it.
So we went down there today and the place was packed. Apparently this guy has a great reputation. It took practically the whole day, but I got the most comprehensive eye exam I have ever had. Several machines, some that I had seen before, and some that I had not. I noticed that the machines that you put your chin on had a tissue liner, which was changed after each patient. A good sign.
The doctor spoke passable English and discussed the whole issue with me. I asked him a trick question about multifocal lenses and he stated firmly that he would NOT allow them to be used in his clinic. He stated that many patients were unhappy with them as they sometimes tended to have a lot of glare, lacked contrast and vision was generally not as sharp. This is exactly what my ophthalmologist back in the States told me a few years ago. His cost ranged from 19,000 to 24,000 baht depending on the type of lens. He recommended a “Hydrophobic Acrylic Aspheric Sperical Aberration“ lens. Even though I have googled it and found several references I still don’t know what the Hell that all means, but hey, the guy is going to be gouging my eyes out so I guess I gotta trust him. Prices are prominently posted, so there is no farang/local price structure. So I was sent off with an appointment date, all kinds of literature to read, and some antibiotic eye drops to take every hour the day of the operation.
So it would seem that in Udon there would be plenty of hospitals or clinics that do this if it’s so popular here. I would start with the major hospital of your choice and go from there. Or perhaps some members who have gone through this recently would care to share their experiences.
