Vision conditions
Astigmatism
Astigmatism causes vision to appear blurred or distorted at any distance. It happens when the cornea or lens has an irregular curve, affecting how light focuses inside the eye. A professional eye assessment can determine the best correction for clear, comfortable vision.
What happens when you have Astigmatism
Understanding age-related changes
In Astigmatism, the cornea or lens is shaped more like a rugby ball than a perfect sphere. This uneven curvature bends light unevenly, making both near and distant vision less sharp. It can occur alone or alongside short‑sightedness (myopia) or long‑sightedness (hyperopia).
Adults — About 3 in 10
Studies show roughly 30% of adults in Singapore have some degree of astigmatism.
Children — Up to 20%
Around 1 in 5 children may also develop astigmatism, often discovered during routine school vision screenings.

“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.

Frequently Asked Questions
We understand that vision correction is a significant decision. Here are honest, transparent answers to the questions we hear most often from our patients.
Astigmatism is a common refractive error where the cornea or lens of the eye is irregularly shaped, causing blurred or distorted vision. It can affect both near and distant vision.
Symptoms include blurred or distorted vision, eye strain, headaches, and difficulty seeing clearly at night.
An eye examination, including a refraction test, is used to measure the degree of astigmatism and how it affects your vision.
Astigmatism can be corrected with eyeglasses, contact lenses, or refractive surgery (such as TransPRK, SmilePro or LASIK), depending on the severity and your individual suitability.
If you’re experiencing blurred or distorted vision, frequent headaches, or difficulty seeing clearly, it’s recommended to arrange an eye examination for proper diagnosis and treatment options.
OneLaser™ TransPRK uses a precise, bladeless laser to reshape the cornea, correcting irregular curves that cause astigmatism. The treatment is tailored to your eye and suitable for those with higher prescriptions or thinner corneas. An assessment determines if OneLaser™ is right for you.
