How diabetes affects the retina
Understanding diabetes‑related eye damage
High blood sugar levels over time can weaken or block the tiny blood vessels that nourish the retina, causing leakage, swelling, or abnormal vessel growth. Without timely care, this may lead to vision loss. Early detection allows management before changes become significant.
Adults with diabetes — About 1 in 3
Roughly one‑third of people with diabetes develop some degree of diabetic retinopathy.
Vision‑threatening stage — 1 in 10
Up to 10% of individuals with diabetes experience the more severe, sight‑threatening form that requires active treatment.

Real stories from the thousands of patients who have trusted us with their sight.
“Dr Huang literally saved my eyesight. After 3 doctors misdiagnosed my severe eye infection in Bali and things were getting worse, I booked a flight to Singapore and set an appointment with Dr Huang. Within 5 minutes of sitting down, he already correctly diagnosed my rare condition and began laying out my treatment plan.”
“One of the best decisions I’ve made! Dr Phi answered all my doubts and worries, and made sure that I’m assured on the procedure process and kindly explain to me every step that is he doing during the procedure itself, which is something I’m so appreciative for!”
“I’d like to thank Dr. Huang for being such a wonderful doctor through my process of getting perfect vision. He was so assuring and put me at ease throughout every step of the way, and conducted my procedure with utmost professionalism and expertise. Post-surgery care was also very well conducted; any concerns I had were addressed and allayed. Thank you so much for the great experience amidst what was initially a scary thing for me.”
I recently had TransPRK procedure done by Dr. Philemon and couldn’t have asked for a better experience. From the very first consultation, he took the time to explain every step in detail, making sure I understood what to expect. He’s very thorough and meticulous. You can tell he cares about his patients and takes pride in doing everything perfectly.
What stood out most was how genuine and attentive he is. He checked in with me before and after the procedure, made sure all my questions were answered, and went above and beyond to make sure I felt cared for.
It’s rare to find someone who’s both exceptionally professional and sincerely compassionate. I sincerely recommend Dr. Philemon to anyone considering refractive surgery.
I’m incredibly grateful to Dr Philemon Huang for the outstanding care and results he delivered. I underwent IOL implant surgery with Dr Huang, and it completely transformed my vision—from being unable to see without glasses to achieving 20/20 vision after surgery.
Dr Huang was clear, professional, and thorough in his recommendations, explaining why LASIK wasn’t suitable for me and why the IOL approach was the best option. His expertise and confidence made the entire process feel reassuring, and the results speak for themselves.
Thank you, Dr Philemon Huang, for your exceptional skill and care. I couldn’t be happier with the outcome.
