What term is used to describe the condition where the natural crystalline lens is replaced with an artificial lens?

  1. Pseudophakia

  2. Miotic

  3. Hypermetropia

  4. Aphakia

The correct answer is: Pseudophakia

Pseudophakia is the term used to describe the condition where the natural crystalline lens is replaced with an artificial lens. This term is derived from the Greek words "pseudo" meaning false and "phakos" meaning lens. The other options are incorrect because miotic refers to a class of drugs used to constrict the pupil, hypermetropia refers to farsightedness or difficulty seeing objects up close, and aphakia specifically means the absence of a crystalline lens either due to surgery or congenital defect.
