Eye Floaters: When to Panic, When Not To
Most floaters are harmless, but some signal a retinal emergency. Learn which symptoms demand same-day review and which can wait for a routine appointment.
Ophthalmologist & Vitreoretinal Surgeon
For when myopia becomes more than just glasses.
Singapore's myopia epidemic is silent — until it isn't. Dr. Wong is the surgeon who understands what decades of high myopia does to the eye, and who operates when it becomes a surgical emergency.
About Dr. Wong
Dr. Chee Wai Wong is Singapore's foremost vitreoretinal surgeon for myopia-related complications — a doctor who has spent two decades studying what high myopia does to the eye over a lifetime, and who operates when it becomes an emergency.
He is simultaneously a surgeon, a researcher with 116+ peer-reviewed publications and H-Index 36, a clinical innovator with an international patent, and a lifelong partner for Singapore families navigating the full arc of the myopia epidemic.
For when myopia becomes more than just glasses — that is when patients need me most. And that moment comes for more Singaporeans every year.

The Myopia Cascade
Most Singaporeans know myopia as a glasses prescription. What they don't know is what happens inside a highly myopic eye over decades — and why catching it early changes everything.
Age 6–10
Myopia begins
Glasses. Normal life. Most parents think the story ends here.
Age 10–20
Progressive myopia
Each dioptre stretches the eye ~0.35mm. At –8D, the eye is significantly elongated.
Age 20–40
Silent structural changes
Retina thins. Lattice degeneration. Risk accumulates invisibly.
Age 40–55
Early complications
Macular traction. Foveoschisis. 10.3% develop macular degeneration within 12 years.
Age 50+
Surgical emergency
Retinal detachment. Macular hole. Surgery within hours or days.

Conditions & Treatments
Dr. Wong's practice focuses on the medical and surgical management of diseases affecting the retina and vitreous. Early intervention is key.
A medical emergency. Dr. Wong offers emergency and elective surgical repair using vitrectomy and advanced techniques to restore and preserve vision.
Age-related macular degeneration (AMD) is the leading cause of vision loss in seniors. Dr. Wong provides intravitreal injections and personalised management plans.
Patients with diabetes are at high risk for retinal damage. Dr. Wong provides laser treatment, intravitreal injections, and surgical care tailored to your condition.
Comprehensive retinal assessment including OCT imaging, fundus photography, fluorescein angiography, and personalised care planning.
Patient Information
Knowledge is reassuring. Dr. Wong believes in empowering patients and their families with clear, jargon-free information about their conditions and treatment options.
Emergency Condition · Surgery Required
The retina is the light-sensitive layer at the back of your eye. When it peels away from the tissue beneath it, this is called a retinal detachment — and it requires urgent medical attention.
Age-Related Condition · Ongoing Management
Age-related macular degeneration (AMD) affects the macula — the central part of your retina responsible for sharp, detailed vision. It is the most common cause of vision loss in people over 60.
Clinic Visit · Friendly & Thorough
Your first appointment with Dr. Wong is a conversation as much as an examination. We take the time to understand your history, concerns, and goals before any investigation or treatment.
Post-Operative Care · Recovery Guide
Recovery after retinal surgery requires careful attention and follow-up. Dr. Wong and his team provide detailed post-operative guidance and are always reachable with concerns.

Excellent care and surgery by Dr Wong. From first consult, the surgery itself and follow up visits were all nicely done. Great thank you to Yolanda the clinic manager and her team for their above and beyond service.
I had eye surgery with Dr Wong Chee Wai to treat a retinal detachment and lens dislocation, and I couldn't be more pleased with the care I received. He clearly explained the condition, surgical plan, and what to expect, which helped ease my concerns going into the procedure. The surgery went smoothly, and my recovery has been progressing well under his attentive follow-up care. Dr Wong is not only highly skilled but also compassionate and thorough. I'm very thankful for his expertise and would confidently recommend him to anyone facing a serious eye issue.
We had a wonderful experience with Dr Wong Chee Wai at Asia Pacific Eye Centre, when bringing in my child for an eye check. The doctor was incredibly patient, gentle, and took the time to make my child feel comfortable throughout the entire process. He explained the diagnosis of myopia clearly and professionally, and gave us helpful guidance on the next steps to manage it. We truly appreciate the care and attention given — it made a potentially stressful visit feel reassuring and positive. Highly recommended!
Dr Wong is very friendly and pleasant to talk to. He made clear and precise explanations prior to my condition. His diagnosis is gentle and he is definitely very experienced in his area of expertise. I know my eyes are in good care under Dr Wong.
Dr Wong Chee Wai performed a surgery for my eye after I suffered with retinal detachment and saved me from going blind. Follow ups with Dr Wong were always pleasant as he is kind, meticulous and takes great care of his patients! Dr Wong and APEC are highly recommended!
I have been seeing Dr Wong Chee Wai for treatment of my dry inflamed eyes. Dr Wong is always professional, attentive, patient and gentle. He takes time to explain in detail and nothing was rushed through for every appointment. So far rather short waiting time for every appointment I was there. It has always been a pleasant experience visiting and I would highly recommend Dr Wong to others.
Dr Wong is an excellent doctor! He listened carefully, explained everything simply, and made me feel at ease. Thank you.
I had vitrectomy done by Dr Wong to fix my retinal detachment, and continued my follow up with him at Asia Pacific Eye Centre. Dr Wong is a highly experienced, caring, and dedicated surgeon. Despite the very complex surgery (I had PVR), he patiently explained everything thoroughly, and made me feel very calm and assured. He had also given many helpful tips on pre and post surgery eye care, resulting in a good visual outcome. Will definitely recommend Dr Wong for his top notch skills and excellent service.
Dr Wong is my favourite eye doctor. He provided clear explanations and took the time to address my concerns. Thank you.
My son was uncomfortable wearing orthokeratology (OK) lenses. We went to Asia Pacific for a detailed eye examination. Dr Wong was very professional and patient, and answered many of our questions. Very satisfied.
