Dr. David Richardson talks about cataracts, cataract Surgery, types of intraocular lenses, and laser cataract surgery or laser-assisted cataract surgery.
LECs are naturally occurring cells that line the capsular bag (which holds the lens in place). Although they provide a needed function in the natural lens, they can be problematic after the natural lens has been replaced by a man-made intraocular lens (IOL).
Ever Wonder What Happened to Waterbed Technology? Don’t Look Now, but Someday It Could Be in Your Eye.
Dr. Louis “Skip” Nichamin gave an interesting talk at the 2013 Hawaiian Eye Meeting titled “Update on a Fluid-based Accommodating IOL.” This technology being developed by PowerVision involves an IOL with the lens optic and haptics filled with silicon oil.
The Electro-Active Accommodating IOL – an experimental intraocular lens (IOL) that changes focus from distance to near, controlled by a computer chip that is part of the IOL itself!
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.
Before we begin the discussion about cataracts and cataract surgery, I’d like to first introduce you to the way the eye works.
