Cataract Surgery Basics. In cataract surgery, the lens inside your eye that has become cloudy is removed and replaced with an artificial lens (called an intraocular lens, or IOL) to restore clear vision.The procedure typically is performed on an outpatient basis and does not require an overnight stay in a hospital or other care facility.hankfully, modern cataract surgery is one of the safest and most effective surgical procedures performed today. More than 3 million cataract surgeries are performed in the United States every year, with the vast majority of these procedures produce excellent visual outcomes.

The Ramus is a branch off the Left Main and lies between the LAD and LCX and not everyone has a Ramus. Instead of the Left Main splitting into 2 vessels (LD And LC) it splits into 3 vessles (LD, LC and Ramus). But the Ramus is considered a branch (and not a vessel)of the either the LD or the LC so the branch rules apply. You are placing a stent on 1 vessel and another stent on a branch of a 2nd vessel with both coming off of the Left Main. Medicare has been pretty clear that they will only consider interventions on the 3 vessles identified by CPT, the LD, LC and RC.
