Basically, the catadioptric telescope is just one of the 3 main types of the optical telescopes.The other 2 main types of optical telescopes are the refracting telescopes and the reflecting telescopes.
Dioptrics is the study of the refraction of light, especially by lenses. Telescopes that create their image with an objective that is a convex lens (refractors) are said to be "dioptric" telescopes.
An early study of dioptrics was conducted by Ptolemy in relationship to the human eye as well as refraction in media such as water. Understanding of the principles of dioptrics was further expanded by Alhazen, considered as the father of modern optics.

Lenses had been known for some time before the telescope was invented. No one really specifically "invented" the telescope lens, they simply used existing equipment (lenses) in a new device (the telescope).
