Floaters and Flashes: When Should You Worry?
Most floaters are harmless, but some are a sign of something serious. Here's how to tell the difference — and when to call your doctor immediately.
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.
