Visualizing Eye Surgery

摘要

The medical establishment already has a very clear picture of cataracts and how to treat them. That's encouraging, given the fact that by age 80, more than 50% of all Americans will have developed a cataract-and every year, more than 3 million will undergo eye surgery to correct it. What is also encouraging is the surgical outcome: the success rate is 95%, with vision typically restored within a 20/20 (normal) to 20/40 (good) range.
