Summary

Vitreous floaters are tiny, cloudy, clumps of cells that appear in the otherwise clear fluid (vitreous) that fills the back 3/4 of the eye. Floaters are commonly caused by eye conditions such as posterior vitreous detachment (PVD), vitreous syneresis and asteroid hyalosis. While these symptoms are considered physiological in nature, they can be of considerable inconvenience to many patients which affect essential activities. The investigators wish to assess the safety and efficacy of floater treatment in patients with highly symptomatic floaters using an FDA approved nanosecond infrared yttrium aluminum garnet (YAG) lasers.

Conditions

• Posterior Vitreous Detachment
• Vitreous Floaters

Interventions

Type	Name	Description
PROCEDURE	Laser Ablation of Floaters
PROCEDURE	Sham Laser Treatment	Laser will be set at 0.3 millijoules (mJ). There will be a 100% absorptive filter (black spot) of about 1cm placed centrally on the lens. All laser aiming beams will be placed within the 1cm filter. Laser will be applied at 0.3 mJ at the absorptive black spot (100% density filter) in order to create a realistic treatment therapy procedure.
