If you have been noticing tiny specks, threads, or cobweb-like shadows drifting across your vision, you are experiencing eye floaters — and you are not alone. They are one of the most common visual complaints we hear at Visual Aids Centre. A question that comes up frequently is whether LASIK can fix floaters at the same time it corrects your glasses prescription.
The short answer is no — LASIK does not get rid of eye floaters. But that does not mean floaters are untreatable or that you should panic. This article explains exactly why LASIK and floaters are unrelated problems, what actually causes those drifting shadows, and which treatments can help if floaters are seriously affecting your quality of life. Understanding the difference will help you set realistic expectations before laser vision correction and make better decisions about your overall eye health.
Key Takeaways
- LASIK reshapes the cornea to correct refractive errors — it does not treat floaters, which originate deeper inside the eye in the vitreous humour.
- Eye floaters are usually harmless and caused by age-related changes in the vitreous gel, though they can occasionally signal a retinal tear or detachment.
- Treatments for bothersome floaters include laser vitreolysis and vitrectomy — not LASIK.
- A sudden increase in floaters, flashes of light, or a shadow across your vision requires urgent medical attention.
What Are Eye Floaters?
Eye floaters are small, shadowy shapes that appear to drift across your field of vision. They are most noticeable against bright, uniform backgrounds — a white wall, a clear sky, or a lit computer screen. Floaters can look like black or grey dots, squiggly lines, thread-like strands, cobwebs, or tiny rings. They seem to move when you move your eyes, and dart away the moment you try to look directly at them.
What you are actually seeing are shadows. Inside the main cavity of your eye sits a clear, gel-like substance called the vitreous humour. When tiny clumps of collagen or other cellular debris form within this gel, they cast shadows on the retina — the light-sensitive layer at the back of the eye. Your brain interprets those shadows as floaters.
What Causes Eye Floaters?
Most floaters are a normal part of ageing. As you get older, the vitreous gel gradually liquefies and shrinks. Collagen fibres within the gel clump together, and these tiny clumps create the shadows you perceive as floaters. People over the age of 50 are most commonly affected, but floaters can appear at any age.
Several factors increase the likelihood of developing floaters. Myopia (nearsightedness) is a major one — highly myopic eyes have a longer axial length, which means the vitreous gel is stretched thinner and more prone to early degeneration. If you are considering LASIK to correct your myopia, it is worth understanding that while the surgery will permanently correct your refractive error, it will not reverse the vitreous changes that cause floaters.
Other causes include posterior vitreous detachment (PVD), where the vitreous separates from the retina; eye inflammation (uveitis); eye trauma; and, in rare cases, retinal tears. PVD in particular is very common after the age of 60 and often produces a sudden burst of new floaters along with flashes of light.
Why LASIK Cannot Treat Eye Floaters
LASIK works exclusively on the cornea — the transparent front surface of the eye. During the procedure, a femtosecond laser creates a thin corneal flap, an excimer laser reshapes the underlying tissue to correct how light focuses on the retina, and the flap is repositioned. The entire process takes place on the outermost layer of the eye and is completed in under 15 minutes per eye.
Floaters, on the other hand, exist inside the vitreous cavity — a completely different anatomical compartment located much deeper within the eye. There is simply no mechanism by which reshaping the corneal surface could affect the vitreous gel or the collagen clumps floating within it. The two problems occupy different parts of the eye and require entirely different solutions.
This is an important distinction for patients considering Femto LASIK, Contoura Vision, or SMILE Pro. All three procedures are excellent at eliminating dependence on glasses for myopia, hyperopia, and astigmatism — but none of them will remove, reduce, or prevent eye floaters.
Can You Get New Floaters After LASIK?
Some patients report noticing floaters for the first time after LASIK. This is not because the surgery caused the floaters — it is because their vision is suddenly much sharper. When you go from blurry, uncorrected vision to crisp 20/20 overnight, pre-existing floaters that were always there become more visible against a newly clear visual field.
In very rare cases, the suction ring used during LASIK can cause a transient spike in intraocular pressure, which could theoretically accelerate a posterior vitreous detachment in someone already on the verge of one. However, this is exceedingly uncommon. If you notice a sudden shower of new floaters, flashing lights, or a curtain-like shadow in your vision after any eye procedure, contact your surgeon immediately — these can be signs of a complication that needs prompt assessment.
Treatments That Actually Work for Floaters
Observation and Neuroadaptation
The majority of floaters are benign and do not require treatment. Over weeks to months, the brain learns to filter them out — a process called neuroadaptation. Your regular eye check-ups will help confirm that the floaters are not related to a retinal tear or other serious condition, after which most ophthalmologists recommend simply giving your brain time to adjust.
Laser Vitreolysis (YAG Laser)
For floaters that significantly impair daily activities — difficulty reading, driving discomfort, or persistent visual disturbance — laser vitreolysis is a minimally invasive option. A YAG laser is used to break large floater clumps into smaller, less noticeable fragments. The procedure is performed in-office, takes about 15–20 minutes, and carries a lower risk profile than surgery. It is not always 100 percent effective, and multiple sessions may be needed.
Vitrectomy
In severe cases where floaters dramatically reduce quality of life, a vitrectomy may be considered. This surgical procedure removes the vitreous gel entirely and replaces it with a saline solution. While highly effective at eliminating floaters, vitrectomy carries risks including cataract formation, retinal detachment, and infection. It is generally reserved as a last resort when other options have failed. If you are exploring this route, a retinal specialist — rather than a refractive surgeon — is the appropriate provider.
Supporting Eye Health
While no supplement can dissolve existing floaters, maintaining overall ocular health may reduce the risk of new ones forming. A diet rich in omega-3 fatty acids, vitamin C, and antioxidants supports the vitreous and retinal tissue. Staying well hydrated and protecting your eyes from UV exposure with quality sunglasses also helps. For patients who have had LASIK, keeping your eyes healthy post-surgery is equally important for long-term visual comfort.
When Floaters Are a Medical Emergency
Most floaters are harmless, but certain warning signs require immediate attention. Seek urgent care if you experience a sudden onset of many new floaters (especially if accompanied by flashes of light), a shadow or curtain spreading across part of your visual field, or any sudden loss of vision. These symptoms may indicate a retinal tear or retinal detachment — conditions that can lead to permanent vision loss if not treated within hours.
At Visual Aids Centre, we perform comprehensive pre-operative retinal evaluations on every LASIK candidate. If we detect signs of PVD, lattice degeneration, or retinal holes during your assessment, we address them before proceeding with vision correction surgery — not after.
Conclusion
LASIK is a remarkable procedure for correcting myopia, hyperopia, and astigmatism — but it does not treat eye floaters. The two conditions affect completely different parts of the eye: LASIK works on the cornea, while floaters originate in the vitreous. If your floaters are mild, neuroadaptation will likely make them far less noticeable over time. If they are severe, laser vitreolysis or vitrectomy are the appropriate treatments — not refractive surgery. Whether you are considering LASIK for clear vision or concerned about persistent floaters, book a consultation at Visual Aids Centre and our team will evaluate both issues and recommend the right path forward.
Frequently Asked Questions (FAQs)
Does LASIK make eye floaters worse?
No. LASIK does not worsen floaters. However, clearer post-operative vision can make pre-existing floaters more noticeable because you are now seeing them through a sharper visual field.
Can I still get LASIK if I have eye floaters?
Yes. Floaters do not disqualify you from LASIK. Your surgeon will perform a thorough retinal examination to ensure the floaters are not linked to a retinal tear or detachment before clearing you for the procedure.
Will floaters go away on their own?
Many floaters become less noticeable over weeks to months as the brain adapts. Some may settle below the line of sight. However, they rarely disappear completely without intervention.
What is the best treatment for severe eye floaters?
Laser vitreolysis is the least invasive option for bothersome floaters. For severe, vision-impairing cases, a vitrectomy (surgical removal of the vitreous gel) is the most definitive treatment, though it carries higher risks.
Are floaters a sign of something serious?
Usually not — most floaters are harmless age-related changes. However, a sudden increase in floaters, flashes of light, or a shadow across your vision can indicate a retinal tear or detachment, which is a medical emergency.
