Can eye floaters be treated without surgery?

Will my floaters settle without treatment?

Usually, yes. Most troublesome floaters appear when the vitreous, the clear gel that fills the eye, shrinks and separates from the retina at the back of the eye. This is called a posterior vitreous detachment. The floaters it brings rarely vanish completely, but over time they tend to sink out of the centre of vision, and the brain learns to filter them out.

In Dr Chen's experience, most people with new floaters are much less troubled by them within about six weeks. There is no reliable study giving an exact percentage or timetable, which is why he generally suggests allowing three to six months before considering any procedure. A minority of people are still genuinely bothered by floaters after many months, and for them the effect on daily life can be real and significant.

This natural improvement matters when judging any treatment. If most people improve anyway, a treatment started soon after floaters appear will often seem to work, whether or not it has done anything.

How do the non-surgical options compare?

Why do floaters bother some people more than others?

Floaters are small clumps and strands of collagen in the vitreous gel. You do not see the clumps themselves. You see their shadows, cast on the retina by the light passing through the pupil.

How noticeable a floater is depends on three things: its size, how close it lies to the retina, and the size of the pupil. A floater close to the retina casts a sharp, dark shadow. The pupil matters because it acts as the light source for the shadow. In bright light the pupil is small, light arrives through a narrow opening, and floater shadows are crisp and easy to see. This is why floaters are most obvious against a blue sky, a white wall or a bright screen, and why they fade in dim light.

This also explains why floaters that look minor during an examination can still be very bothersome, and why the brain's ability to ignore them varies so much from person to person. Floaters are associated with measurable anxiety for some people, and simply being reassured that the retina is healthy often helps more than any product.

What is VitroCap N and what is in it?

VitroCap N is an oral supplement sold in Australia for floaters. It was developed in Germany, and Dr Chen now sees many patients who have been advised to try it by their optometrist.

Each daily capsule contains:

The recommended course is one capsule a day with food for at least three to six months. At the time of writing it costs about $85 for a 90-day supply when bought online from the Australian distributor.

VitroCap N is a listed complementary medicine. Listed medicines may only contain ingredients the Therapeutic Goods Administration accepts as low risk, and the company certifies that the product meets the listing rules. The TGA does not assess a listed product before it goes on sale, and it does not assess whether it works.

The manufacturer suggests the ingredients protect the collagen and gel of the vitreous from age-related damage, through antioxidant effects and by reducing the chemical stiffening of collagen that comes with age. These ideas come from laboratory studies. There is no independent evidence that this combination, taken by mouth at these doses, changes the vitreous in people, and the trial researchers themselves did not measure whether the ingredients reached the eye. It is not obvious why this particular mix of ingredients was chosen.

What did the VitroCap N study find?

The main evidence is the FLIES trial, published in 2021. Sixty-one adults with floaters in Ireland were randomly given either the supplement or an identical dummy capsule for six months, without them or the researchers knowing which.

Among the 56 people who finished the study, those taking the supplement reported less discomfort from their floaters at the end than at the start, and in the 47 people whose photographs could be analysed, the total area of floaters was smaller. The placebo group improved only slightly: their average discomfort score fell a little, but not significantly, and their measured floater area rose slightly, also not significantly. Visual acuity did not change in either group. One of several contrast sensitivity measures improved slightly with the supplement.

How much should the VitroCap N study be trusted?

Taken at face value the results are encouraging, but several features make them much less certain than the headline suggests.

• Natural improvement was not accounted for. The study did not record how long people had had their floaters. Because new floaters usually settle on their own, the placebo group would be expected to improve noticeably too. It improved only slightly, which is surprising.
• The main measure was a questionnaire written for this study and not tested elsewhere. The widely quoted figure of about two in three people benefiting was calculated by adding together changes in several answer categories, so the same person can be counted more than once. Calculated the same way, the placebo group's figure was about one in four.
• Each group was mainly compared with itself. The conclusions rested on before-and-after comparisons within each group; the paper reports only one direct comparison between the groups, in its discussion rather than its results tables.
• Floater areas were outlined by hand on photographs by a single researcher, one of the patent's named inventors, although they did not know which group each person was in.
• It was small and has not been repeated. Only people who finished were analysed, and no independent trial has confirmed the result. Earlier supportive studies were uncontrolled or not blinded, and are mainly promoted by the manufacturer.
• There are commercial links. The supplement's maker part funded the study and has a royalty agreement with the university, and two researchers, including the senior author, are named inventors on a pending patent for the formulation.

None of this proves the supplement does not work, but the evidence is weak and needs a larger independent trial.

Dr Chen's view. He remains sceptical. He has not seen a convincing explanation of how these ingredients would clear floaters, and suspects most of the benefit people notice reflects natural settling and the placebo effect; he would want people with long-standing floaters to report a clear benefit before recommending it. Even so, he mentions it as an option. It appears to be low risk, so if someone is happy to spend the money and try it for a few months, there is little harm, provided it does not replace an eye examination for new symptoms.

How do dilating eye drops make floaters less noticeable?

Drops that enlarge the pupil can make floaters much less visible. With a wide pupil, light reaches the retina from a broad cone of directions, so a floater blocks only part of it and its shadow becomes a faint, blurred patch instead of a small dark spot.

Small pupil (bright light)

Narrower light bundle: darker, sharper floater shadow (higher contrast)

Large pupil (dim light or dilating drops)

123+

Broader light bundle: lighter, more diffuse floater shadow (lower contrast)

The problem is the side effects. Full-strength dilating drops cause light sensitivity and glare, blurred vision, and, in people who have not had cataract surgery, loss of the eye's ability to focus up close for hours or days. Very few people tolerate this for long, so standard dilating drops are not a practical long-term treatment, even though they work well optically.

Can low-dose atropine drops help?

Low-dose atropine is an attempt to find a middle ground: a dose weak enough to be tolerable, but strong enough to widen the pupil a little and soften floater shadows. Atropine is usually used at 1% strength to dilate the pupil fully. The low doses used for floaters, typically 0.01%, are the same concentrations used to slow short-sightedness in children, where they widen the pupil by about half a millimetre on average in children. In young adults the effect can be larger: in one small study, a single 0.01% drop widened the pupil by more than a millimetre and reduced near focusing for about a day. Higher strengths such as 0.05% widen the pupil further, but reduce near focusing more.

The evidence for floaters is limited. The main published study, from a retina practice in the United States in 2025, looked back at 44 adults whose floaters had persisted for at least three months who were prescribed 0.01% atropine once a day. Only half used the drops for at least a week. Of those 22, 13 were satisfied and 11 wanted to continue, while about one in five reported worse near vision, and similar numbers reported worse distance vision or light sensitivity. There was no comparison group and follow-up was only one week, so a placebo effect cannot be excluded. A larger study led by the same investigator was registered in late 2023, again without a comparison group. Its status has not been updated since, and no results have been posted.

Some clinics overseas sell low-dose atropine specifically for floaters. A well-known example is a US floater practice that supplies custom-diluted atropine in several strengths after a telehealth consultation. In Australia, low-dose atropine is registered only for slowing myopia in children, so using it for floaters is off-label and needs a prescription; strengths outside the registered range need a compounding pharmacy.

It is most likely to be worth trying for someone who has already had cataract surgery, because their near focusing no longer depends on the natural lens. Younger people who still focus naturally are more likely to notice blurred reading vision. Any dilating drop can trigger acute angle-closure glaucoma in an eye with a narrow drainage angle, so the angle should be checked by an eye specialist before starting.

Do pineapple, bromelain or other enzyme supplements work?

Bromelain, an enzyme from pineapple, and papain, from papaya, can break down proteins, which is why they are promoted to "dissolve" floaters. A laboratory study found that enzymes, including bromelain, can partly reverse the light scattering caused by gel artificially aged with enzymes, but that was in pig vitreous in a dish.

+

One trial from Taiwan in 2022 gave 160 people with ordinary floaters capsules of bromelain, papain and ficin at different doses for three months, and reported floaters disappearing in 55% to 70% of eyes, compared with 5% of eyes in the group given a vitamin C tablet instead. The result has not been repeated, the capsule was developed by the researchers themselves, and, as with VitroCap N, the near-absence of improvement in the comparison group is hard to reconcile with how often floaters settle naturally. There is no good evidence that eating pineapple helps.

Enzyme supplements such as bromelain and nattokinase can increase bleeding tendency, which matters for people taking blood thinners. There is no trial evidence for serrapeptase, hyaluronic acid, ginkgo, bilberry or other products sold as floater formulas.

Are there eye drops that dissolve floaters?

No. Drops applied to the surface of the eye cannot reach the vitreous in meaningful amounts to break up collagen clumps. Iodine-based drops have been used for floaters in some countries, but the supporting studies are decades old and poorly controlled. Other drops sold online for floaters have no reliable evidence, and some imported eye drops have been recalled or subject to regulatory warnings overseas because of contamination or unapproved claims. Unregulated eye drops can cause serious eye infections, so they are best avoided.

What helps day to day?

Simple measures reduce how often floaters catch your attention, even though they do not remove them.

+

• Sunglasses or tinted lenses in bright light, which soften glare and bright backgrounds.
• Avoiding very bright, plain backgrounds where possible, such as turning down screen brightness or using a darker screen theme if you find it helps.
• Moving your eyes briefly up and down or side to side, which can shift a floater out of your line of sight for a while.
• Not watching for them. The more attention floaters receive, the more noticeable they become; the brain adapts faster when they are not being monitored.

These are sensible suggestions from eye professionals rather than proven treatments. There is no evidence that eye exercises, drinking more water, massage, diet or blue-light filters make floaters go away.

If floaters are making you anxious or low in mood, it is worth saying so. Knowing the retina is healthy helps many people, and some benefit from talking with their GP.

What treatments are still being researched?

Researchers are exploring ways to break up floaters without surgery. One approach injects tiny particles into the eye that attach to floater clumps; a gentle laser then produces microscopic bubbles that break the clumps apart. It has worked in rabbits and in samples of human vitreous removed at surgery, but has not been tested in people. Drugs that liquefy or loosen the vitreous have been studied for other conditions, but are not used for floaters and can themselves cause new floaters. None of these is available as a treatment.

When are laser or surgery worth considering?

If floaters are still interfering with reading, driving or work after several months, a procedure may be worth discussing. YAG laser for floaters can help selected people with a single, well-defined floater positioned safely away from the lens and retina. A randomised trial found it improved symptoms compared with a sham treatment in people with a ring-shaped floater.

For floaters that remain troublesome despite time, vitrectomy removes the gel and the floaters within it. It is effective but carries real risks, including an earlier cataract and a small risk of retinal detachment. The page on floaters and floater surgery explains how the options are weighed, and the article on recovery after vitrectomy for floaters describes what surgery involves afterwards.

When do floaters need urgent attention?

No supplement, drop or waiting period is appropriate for new symptoms that could mean a retinal tear. About one in seven people who develop a sudden burst of floaters or flashes has a retinal tear at their first examination. Contact your ophthalmologist urgently, or attend an emergency department, if you notice:

• a sudden shower of new floaters
• new flashes of light
• a shadow or curtain spreading across your vision
• a sudden drop in vision

The article on flashes, floaters or a curtain in your vision explains these warning signs in more detail.
