What is vitreolysis and how does it work?
Vitreolysis is an outpatient laser treatment for eye floaters, the drifting specks, threads and cobweb shapes that many people see against a bright background. Floaters are clumps of collagen fibres or a ring of tissue floating in the vitreous, the clear gel that fills the back of the eye. Each one casts a shadow on the retina. In vitreolysis an ophthalmologist uses a YAG laser, with a special contact lens, to fire very short pulses at the floater. The pulses vaporise or fragment it so that it casts a smaller, fainter shadow or stops crossing the line of sight. Vitreolysis in Turkey is offered by eye hospitals that already use YAG lasers for other procedures.
This guide explains how the laser is aimed, what the research shows and does not show, who should not have it, what it costs against the UK, US and Germany, and what to ask a clinic. For other eye procedures see our eye treatments in Turkey.
Why do floaters appear, and when are they harmless?
With age the vitreous gel shrinks and liquefies, and its collagen fibres clump. The gel may then peel away from the retina, an event called posterior vitreous detachment (PVD). Many people notice a large ring-shaped floater, often called a Weiss ring, after a PVD. Short-sighted people and people who have had cataract surgery tend to see floaters earlier. Most floaters are harmless and become less noticeable over months as the brain learns to ignore them.
Some changes are not harmless. A sudden shower of new floaters, flashes of light, or a dark curtain or shadow spreading across your vision can mean a retinal tear or detachment. As the NHS advises, that needs same-day assessment by an eye specialist, not a laser appointment. No clinic should treat floaters before examining the retina through a dilated pupil.
Does vitreolysis work? What the evidence says
The honest answer is that it can help some people, but the research is limited. A small number of controlled trials, including a published sham-controlled trial of YAG vitreolysis for symptomatic floaters, reported that a proportion of treated patients had meaningful improvement in symptoms. Reviews by ophthalmology bodies note that studies are few, short and small, that results depend on the type and position of the floater, and that some patients need more than one session or see no change.
Evidence is best for a single, well-defined floater lying a safe distance from the lens and the retina, such as a Weiss ring. It is weakest for diffuse cloudy floaters and for floaters sitting close to the retina, which a laser cannot safely reach. A trustworthy clinic will measure your floater on a scan, say whether it is treatable and avoid promising that every floater will disappear.
Who is a good candidate for laser floater treatment?
Suitable patients usually have floaters that have been stable for at least three to six months, that interfere with reading, driving or screen work, and that lie well forward of the retina. A dilated retinal examination should show no tears, no detachment and no other disease. You are usually less suitable if your floaters are very recent, if the vitreous is cloudy throughout, if the floater is close to the retina, or if you have uncontrolled glaucoma, an active eye infection or significant inflammation. People with a clouded cornea or lens may also be unable to be treated because the laser beam must pass cleanly through the eye.
If your problem is a squint or double vision rather than floaters, a different specialist is needed; our guide to strabismus surgery covers that separate condition.
How much does vitreolysis cost in Turkey compared with the UK, US and Germany?
The figures below are approximate ranges per eye for the laser session, not hospital quotes. Vitreolysis is generally treated as elective, so health systems and insurers rarely fund it and patients pay privately in all four countries. Each hospital confirms its own price in a written quote.
| Country | Approximate cost range (per eye) |
|---|---|
| Turkey | €400 – €1,500 |
| United Kingdom | €800 – €2,800 |
| United States | €1,000 – €3,500 |
| Germany | €700 – €2,500 |
What changes the price: the number of sessions planned, whether one or both eyes are treated, the imaging done beforehand (optical coherence tomography and a retinal photograph) and whether the quote includes the dilated retinal check and follow-up visits. A package normally covers the consultation, the examination, the laser session itself and a review a few days later. Ask what happens if a second session is needed and whether it is charged.
Vitreolysis step by step: what happens on the day
You arrive for a full eye assessment: visual acuity, eye pressure, a dilated retinal examination and usually an OCT scan or an ultrasound of the vitreous. If the floater is suitable, the pupil is dilated and numbing drops are applied. You sit at the laser microscope with a contact lens resting on the eye. The ophthalmologist focuses the aiming beam on the floater and fires pulses; you may see small flashes and bubbles of gas, and hear the laser clicking. A session often lasts 15 to 30 minutes per eye. There is no cut and no general anaesthesia. Afterwards your vision is blurred from the dilating drops for a few hours, so you should not drive.
Some floaters need two or three sessions spaced weeks apart. The ophthalmologist will not keep firing if the floater cannot be reached safely.
Vitreolysis, waiting or vitrectomy: how do they compare?
For floaters there are three realistic paths. Observation costs nothing and works for most people, because the brain adapts. Vitreolysis is a quick laser option for selected floaters. Vitrectomy is a surgical operation that removes the vitreous gel and the floaters with it; it is more certain at clearing floaters but is a retinal operation with greater risks, such as cataract, retinal tear and detachment, so it is normally kept for severe cases. Our guide to photocoagulation describes another laser used inside the eye, for a different purpose.
| Option | Best suited to | Typical limits |
|---|---|---|
| Waiting and adapting | Mild, recent or fading floaters | Floaters may persist for months |
| YAG vitreolysis | Single, well-defined floater away from the retina | Limited evidence; may need repeat sessions |
| Vitrectomy | Severe floaters that disable daily life | Operating-theatre surgery with greater risk |
What results can I realistically expect?
Before-and-after expectations are different for floaters because the change is in what you see, not in how the eye looks. Photographs cannot show it. What patients report is a smaller, paler or absent shadow. After treatment some notice a short-lived rise in new tiny floaters from the fragments, which usually settle. Some feel a clear improvement, some a partial one and some none. Results are judged by your own symptoms after four to eight weeks. Floaters can also form again later, because the ageing of the vitreous continues.
How long is recovery, and how long should I stay in Turkey?
Vitreolysis recovery is short. Most people resume normal activities the next day, avoiding heavy lifting and eye rubbing for a few days. Mild eye ache, light sensitivity or a gritty feeling can occur and is usually brief. A review within a week checks eye pressure and the retina. For a single treatment most patients allow two to three nights in Turkey so that the pre-treatment checks, the laser and the follow-up can be done without rushing. A second session, if planned, may be spaced a few weeks apart, so ask the clinic whether it can be done on a later visit or locally.
What are the risks and side effects of vitreolysis?
Every eye procedure carries risks. Reported effects include temporary blurring, a transient rise in eye pressure, inflammation, new floaters from laser debris, laser marks on the lens that can contribute to cataract, and, rarely, a retinal tear or bleeding if the laser strikes the retina. Because the treatment is delivered inside the eye, the position of the floater is the main safety factor. Professional bodies such as the Royal College of Ophthalmologists and the American Academy of Ophthalmology note the limited evidence and advise careful selection. Ask the surgeon what the specific risks are for your floater and what the plan is if you develop flashes or a shadow after you return home.
How do I choose an eye hospital for vitreolysis?
Choose a hospital where an ophthalmologist, preferably with retinal or vitreous experience, examines you in person or reviews your scans before agreeing to treat. Look for a dilated retinal examination and OCT imaging before any laser, a written explanation of why your floater is treatable, and a clear plan for aftercare and emergencies. Red flags include promises that all floaters will vanish, treatment without a retinal check, a quote with no breakdown, pressure to pay a deposit quickly and no named doctor.

Questions to ask the clinic:
- Will you examine my retina with dilated pupils and scan the vitreous before treatment?
- Is my floater suitable, and how far is it from the retina and the lens?
- How many sessions might I need, and is each one charged?
- What are the risks for my eye, and how do you treat a retinal tear if it happens?
- Who will review me if I notice flashes or a shadow after I fly home?

Frequently asked questions
Vitreolysis is a laser treatment for eye floaters. A YAG laser fires short pulses at a floater inside the vitreous gel to break it up or vaporise it, so that it casts a smaller shadow on the retina. It is done as an outpatient procedure.
It helps some people, particularly those with a single, well-defined floater well away from the retina. The research is limited and small, and some patients see only partial improvement or none, so a clinic should explain your chances honestly.
Approximate costs are €400 to €1,500 per eye in Turkey, against about €800 to €2,800 in the UK. The price depends on the number of sessions, the imaging done beforehand and the follow-up included; the hospital confirms it in writing.
Numbing drops are used and most people feel little more than pressure from the contact lens and the clicks of the laser. Mild eye ache or light sensitivity can follow and usually settles within a day or two.
Most people return to normal activities the next day, once the dilating drops have worn off. Heavy lifting and eye rubbing are usually avoided for a few days, and a check-up within a week reviews eye pressure and the retina.
Treated floaters do not return, but the vitreous continues to age, so new floaters can appear later. Some patients need more than one session to reach the improvement they hoped for.
It is generally considered low-risk when carefully selected, but complications can include raised eye pressure, inflammation, new floaters, lens marks and, rarely, retinal damage. Safety depends heavily on the floater being a safe distance from the retina.
Vitreolysis is a laser that breaks up selected floaters in a short outpatient session. Vitrectomy is an operation that removes the vitreous gel itself; it clears floaters more reliably but carries greater risks, so it is kept for severe cases.
A sudden shower of new floaters, flashes of light or a dark curtain across your vision can signal a retinal tear or detachment. This needs same-day examination by an eye specialist, before any floater treatment is considered.
Two to three nights is usual for a single treatment, which allows the retinal examination, the laser and a follow-up check without rushing. If a second session is planned, ask whether it can happen on a later visit.
