Laser Floater Removal involves the application of nanosecond pulses of low-energy laser light to evaporate the vitreous opacities and to sever the vitreous strands. During this process, the laser energy evaporates the collagen and hyaluronin molecules to form a gas. The end result is that the floater is removed and/or reduced to a size that no longer impedes vision.
Laser Floater Removal is performed as an outpatient procedure; you do not have to stay overnight in a hospital. Immediately prior to treatment, your ophthalmologist will administer eye drops to prepare the eye and to provide mild anesthesia. A contact lens will then be placed on your eye, with the laser light delivered through a specially designed microscope.
During treatment, you will likely observe small, dark specks/shadows – signaling that the floaters are being evaporated into small gas bubbles. These gas bubbles quickly dissolve and reabsorb into the vitreous humor.
Once the treatment is complete, your ophthalmologist may treat your eyes with anti-inflammatory drops. It is important to note that most patients will need to undergo two treatment sessions, sometimes three, in order to achieve a satisfactory result. As there is no inflammation post-treatment, these sessions can be performed on consecutive days.
You may observe small, dark specks in your lower field of vision immediately following treatment, but these small gas bubbles will quickly dissolve and will not impede vision.
It is also important to note that some patients may experience mild discomfort, redness or temporarily blurred vision directly following treatment.
Reported side effects and complications associated with laser floater removal are rare. Side effects may include cataract and intraocular pressure (IOP) spike.
While some floaters can be effectively treated, several floater types are difficult to treat and/or less likely to regress than others. To that end, it is necessary to first undergo an ophthalmic examination in order to determine your eligibility for laser floater removal treatment.
Generally-speaking, if you suffer from persistent moving shadows in your vision due to vitreal condensations, fibers, strands, and/or clouds, you are a good candidate for laser floater removal. A number of factors, such as age, onset of symptoms and floater characteristics, will also determine whether laser floater removal is your best treatment option.
Criteria for Laser Floater Removal:
Stable floater (PVD) of greater than six months duration
No flashes of light
Visually-significant and interfering with activities of daily living
Individual has had prior cataract surgery
In most cases, younger patients (<45) suffer from microscopic floaters located close to the retina (1-2 mm) and are not considered to be good candidates for laser floater removal treatment.
If your floater symptoms came on very quickly then they may be associated with a posterior vitreous detachment (PVD), the characteristics of which can be effectively treated with laser floater removal.
Large floaters with a soft border, situated away from the retina, are ideally suited to treatment with laser floater removal.
