He has done several eye surgeries and shows extreme compassion. He is the most amazing doctor I have had the pleasure of meeting. Dr. Tan is one of a kind!~RM I found Dr. Tan a patient and caring man who took time to listen to my many questions. When my surgeries were performed in early 2016 I had total confidence in his great skill and experience. My eyesight is much improved and I am mostly free of glaucoma drops. The quality of my life has improved.~JM We want to let you know how grateful we are with your recent surgery. He is a different person now and able to use the minimal sight in both eyes. Thank you for the wonderful work you performed on both eyes. We can never thank you enough for all you did.~HT After years of struggling to find a doctor to help control my glaucoma, I was lucky to find Dr. Tan.
