This procedure utilizes a Neodymium:Yttrium-Aluminum Garnet (Nd:YAG) laser to vaporize floaters within the eye. The Nd:YAG laser is commonly used in other eye procedures including posterior capsule opacification and peripheral iridotomy. When applied to the treatment of vitreous floaters, the laser energy is focused through the cornea and lens and onto the surface of the floater. Upon discharge, a plasma field is formed which converts the collagen fibers, hyaluronic acid, and proteins in the floater into a gas bubble which is absorbed by the retina/blood stream. Complete elimination of a floater may require multiple (~100 – 300), manually targeted, ‘shots’ and several office visits.
Laser vitreolysis is generally considered to be safer than a classic, surgical vitrectomy since it is less invasive. Despite a variety of studies describing this procedure as a treatment for vitreous floaters, it is not widely practiced. This is perhaps due in part to its limitations. Since floaters must be seen to be targeted, it is common for small floaters or floaters close (2-5mm) to the retina to remain after treatment or be untreatable. It is however, ideal for patients with large, well-suspended floaters in the mid-vitreous who are seeking a reduction in the number of floaters within their visual field.
