Laser capsulotomy is a surgical therapy used to remove an opacified posterior capsule. The opacified posterior capsule is a clouding of the membrane behind the intraocular lens implant that causes blurring. The laser is used to cut a hole in this cloudy membrane, in order to improve your vision. The laser is a tiny but powerful beam of light that can make a small burn or opening in tissue. Light passes harmlessly through the outer covering of the eye and is used to create an opening in the cloudy membrane.
