You’re Going To Vacuum Out My Eye?

Imagine you have a plastic trash bag (the cheap thin ones from a discount store, not the Heavy Duty Hefty bag) – this is going to be our imaginary capsular bag. In the eye this bag is only a few millionths of a meter thick. Now fill it up with oatmeal – this is our model cataract. Now, in order to remove the cataract we are going to use an instrument that both pours fluid into the bag and vacuums the oatmeal out of the bag.
