Which term refers to an implant placed in front of the iris or in the capsular bag to replace the natural lens?

Explanation:
An intraocular lens, or IOL, is the implant used to replace the natural crystalline lens after cataract removal. It can be placed in front of the iris in the anterior chamber or behind the iris within the capsular bag (the posterior chamber). The most common approach is to place the IOL in the capsular bag, which sits where the natural lens used to be, providing stable optics and natural focusing. An anterior chamber IOL is used when the capsular bag isn’t suitable but carries different risks. The other terms refer to tissues or conditions, not implants: epithelium is a cellular layer, fornix is a conjunctival fold, and an epithelial defect is a surface injury.
