Floaters After Eye Surgery: What Is Normal and What Is Not
Expert guidance from Dr. Daniel Baik at Nunehim Eye Center, Yeongdeungpo-gu, Seoul
Q. Are floaters after eye surgery normal?
Yes — some degree of floaters after eye surgery is normal and expected, particularly following cataract surgery, vitreoretinal procedures, LASEK/TransPRK, or intravitreal injections. However, a sudden dramatic increase in floaters, new flashes of light, a shadow or curtain across vision, or loss of central vision after surgery warrants immediate evaluation at an ophthalmology clinic in Seoul. At Nunehim Eye Center in Yeongdeungpo, we distinguish post-surgical floaters from warning signs of retinal detachment and other complications.
Q. What exactly are eye floaters?
Floaters are small deposits of protein, blood cells, or vitreous debris that cast shadows on the retina as light passes through the eye. They appear as dots, threads, cobwebs, or translucent shapes drifting across your visual field — especially visible against a bright background such as a blue sky or white screen. After eye surgery, the vitreous (the gel filling the back of the eye) may be disturbed, accelerating floater formation or causing existing floaters to become more noticeable.
📊 Floaters & Surgery: Key Facts in Korea
- ▸ Korea has one of the world’s highest rates of high myopia — over 96% of young adults are myopic in Seoul
- ▸ Highly myopic eyes have a 6–8× higher risk of posterior vitreous detachment and retinal tears
- ▸ Cataract surgery is the most commonly performed surgical procedure in Korea, with floaters reported in up to 20% of post-op patients
- ▸ Retinal detachment, if floaters are a warning sign, requires treatment within 24–72 hours for best visual outcomes
Q. What types of floaters are expected after surgery vs. warning signs?
After most eye surgeries in Seoul, including cataract surgery and TransPRK/2-Day LASEK at Nunehim Eye Center, patients may notice new or worsened floaters in the days to weeks following the procedure. This is typically a result of vitreous disturbance and is generally benign. However, certain floater patterns require urgent assessment.
Q. What floaters are considered normal after cataract or refractive surgery?
After cataract surgery, new floaters — particularly a ring-shaped or arc-like floater — often represent the detachment of the posterior vitreous face from the optic disc (posterior vitreous detachment, or PVD). This is extremely common in patients over 60, and in younger highly myopic patients across Seoul’s Guro, Gasan, and Gwanak districts who undergo surgery. A PVD floater typically fades over weeks to months as the brain adapts.
After TransPRK or 2-Day LASEK (the refractive procedures offered at Nunehim Eye Center), floaters are not a direct consequence of the surgery itself — which affects only the cornea — but patients with high myopia may notice pre-existing floaters more acutely after vision correction, when their sight is clearer.
Q. What floater symptoms after surgery require urgent care in Seoul?
Contact Nunehim Eye Center or go to an emergency eye clinic in Seoul immediately if you experience: a sudden shower of new floaters (like a snowstorm), flashes of light (photopsia) in peripheral vision, a dark shadow or curtain creeping in from any side of your vision, or any sudden loss of central or peripheral vision. These may signal retinal tear, retinal detachment, vitreous hemorrhage, or endophthalmitis — a serious infection.
In Yeongdeungpo, Guro, and Gasan districts, Nunehim Eye Center offers urgent slot appointments for post-surgical concerns. Early intervention — within hours for retinal detachment — dramatically improves visual outcomes. Do not wait to “see if it gets better” with these symptoms.
Q. Which post-surgical floater symptoms are emergencies?
- Sudden shower of new floaters — possible vitreous hemorrhage or retinal tear
- Flashing lights (photopsia) — traction on the retina, risk of detachment
- Dark curtain or shadow in vision — retinal detachment until proven otherwise
- Reduced vision + red painful eye — possible endophthalmitis (surgical infection) — ophthalmic emergency
- Floaters + high fever after injection procedure — rule out endophthalmitis urgently
🔬 After Cataract Surgery
New ring or arc floaters (PVD) are common and usually benign. Full floater assessment at 1-week and 1-month post-op at Nunehim Eye Center, Seoul.
👁️ After LASEK/TransPRK
Pre-existing myopia-related floaters may become more visible after clearer vision is restored. New floaters after corneal-only surgery should still be checked — especially in high myopes in Guro or Gwanak.
💉 After Intravitreal Injection
Transient floaters from the injection bubble are expected and typically disappear within 24 hours. Persistent or new floaters plus pain after injection requires same-day evaluation.
From Dr. Daniel Baik, Board-Certified Ophthalmologist
“Post-surgical floaters are one of the most common concerns I hear from patients at Nunehim Eye Center in Yeongdeungpo. The key message: not all floaters after surgery are dangerous, but none should be ignored. In Seoul, where myopia rates are among the highest in the world, the risk of surgery-related retinal complications is real — but with timely evaluation, almost all serious outcomes are preventable.”

❓ Frequently Asked Questions: Floaters After Eye Surgery
Q. How long do floaters last after cataract surgery in Seoul?
Most post-cataract surgery floaters related to PVD become less noticeable over 3–6 months as the brain adapts (neuroadaptation). The floaters themselves do not disappear, but most patients stop noticing them in normal daily activities in Guro, Gwanak, and Yeongdeungpo. Floaters that remain severely bothersome after 6 months can be discussed with Dr. Daniel Baik — in rare cases, vitrectomy may be considered.
Q. Can floaters after surgery be treated with laser?
YAG laser vitreolysis is a procedure that uses laser energy to vaporize floaters. It is available in some Korean ophthalmology clinics but is not universally recommended due to limited evidence of long-term efficacy and a small risk of retinal damage. Vitrectomy (surgical removal of the vitreous) is more reliably effective but carries its own surgical risks. At Nunehim Eye Center, Dr. Daniel Baik will discuss all options in the context of your specific case.
Q. I had LASEK/TransPRK and now see more floaters. Is this normal?
Yes, this is a well-recognized phenomenon. Before LASEK or TransPRK, blurry vision from myopia effectively “hides” pre-existing floaters. After surgery successfully corrects your vision at Nunehim Eye Center, the newly sharp optics make floaters more visible — even though you had them all along. A dilated fundus exam before or after surgery rules out any retinal pathology, which is especially important for high myopes in the Gasan and Guro area.
Q. Is a floater the same as a posterior vitreous detachment (PVD)?
Not exactly — but they are closely related. A PVD is the separation of the vitreous gel from the retinal surface, which commonly produces a characteristic large ring-shaped floater (Weiss ring). PVD is extremely common over age 60 and in myopic patients of all ages across Seoul. While PVD itself is usually benign, it carries about a 15% risk of causing a retinal tear at the time of separation, which is why new PVD symptoms require prompt dilated examination.
Q. Can OK lens (orthokeratology) cause floaters?
OK lens wear does not directly cause floaters. OK lenses reshape the cornea during sleep to temporarily reduce myopia — they do not interact with the vitreous or retina. However, patients with high myopia who use OK lenses (a specialty at Nunehim Eye Center) are still at elevated risk of myopia-associated vitreoretinal changes. Regular retinal checks alongside OK lens management are standard practice at our clinic in Yeongdeungpo-gu.
Q. What follow-up schedule should I expect after eye surgery in Seoul?
At Nunehim Eye Center, post-surgical follow-up typically includes: Day 1 (or Day 2 for LASEK), Week 1, Month 1, and Month 3 check-ups. Retinal examination is incorporated for all patients with high myopia. If you develop new floaters between scheduled visits — particularly if sudden or accompanied by flashes or visual field changes — contact the clinic for an urgent slot rather than waiting for your next appointment.
Q. Are expat patients in Seoul welcome at Nunehim Eye Center?
Absolutely. Dr. Daniel Baik conducts consultations in both Korean and English.
