Laser vitreolysis is a possible treatment option for the removal of vitreous strands and opacities (floaters). In this procedure an ophthalmic laser (usually a yttrium aluminium garnet (YAG) laser) applies a series of nanosecond pulses of low-energy laser light to evaporate the vitreous opacities and to sever the vitreous strands.
A ring of floaters or hairs just to the temporal side of the central vision As a posterior vitreous detachment proceeds, adherent vitreous membrane may pull on the retina. While there are no pain fibers in the retina, vitreous traction may stimulate the retina, with resultant flashes that can look like a perfect circle.
Nd:YAG lasers are used in ophthalmology to correct posterior capsular opacification, [6] after cataract surgery, for peripheral iridotomy in patients with chronic [7] and acute angle-closure glaucoma, [8] where it has largely superseded surgical iridectomy, [9] for the treatment of vitreous eye floaters, [10] for pan-retinal photocoagulation in ...

Even after treatment, it can take months for the body to clear all of the blood from the vitreous. [2] In cases of vitreous hemorrhage due to detached retina, long-standing vitreous hemorrhage with a duration of more than 2–3 months, or cases associated with rubeosis iridis or glaucoma , a vitrectomy may be necessary to remove the standing ...
Treatment with Nd:YAG lasers and with Nd:YAG laser passed through a Potassium titanyl phosphate crystal, and with an argon laser has been studied in small clinical trials. [11] Nd:YAG laser has been abandoned due to risks of damaging the colon wall, fibrosis, stricture formation, and recto-vaginal fistula, and severe damage in case of accidents ...
Laser eye surgery or laser corneal surgery is a medical procedure that uses a laser to reshape the surface of the eye to correct myopia (short-sightedness), hypermetropia (long-sightedness), and astigmatism (uneven curvature of the eye's surface). Importantly, refractive surgery is not compatible with everyone, and people may find on occasion ...
