Note that most of the ozone is in the lower stratosphere. The ozone layer resides at an altitude of about 12 to 15 miles (20 to 25 kilometers) above sea level. It acts as a shield by absorbing biologically active ultraviolet light (called UV-B) from the sun.
Yag Laser Capsulotomy. Your eyeâs normal lens is like a grape, having an outer skin and in inner gel like material. When a cataract forms, the material inside the lens (nucleus) turns cloudy and interferes with good vision. Cataract surgery removes the cloudy lens and replaces it with an intraocular implant.

In YAG Laser Capsulotomy, a laser is used to create an opening in the hazy capsule situated behind the IOL implant to allow you to see more clearly.
