Disclosed is a portable model eye apparatus for intraocular lens evaluation that enables more accurate comparison of intraocular lenses by capturing the same image and situation for different intraocular lenses. A portable model eye apparatus for intraocular lens evaluation according to an aspect of the present invention may include a beam splitter configured to emit an incident light source in two directions at right angles to each other; a pair of corneal modules including a first corneal module and a second corneal module disposed in a first emission direction and a second emission direction of a light source, respectively; a pair of intraocular lens modules including a first intraocular lens module disposed behind the first corneal module along the first emission direction, and a second intraocular lens module disposed behind the second corneal module along the second emission direction; and a pair of camera modules disposed behind the pair of intraocular lens modules, respectively, to obtain images emitted.

An optical bench tester for a multifocal intraocular lens is disclosed. An optical bench tester for a multifocal intraocular lens according to an aspect of the present disclosure may include a resolution test chart; a plurality of optical systems that refract images irradiated from the resolution test chart; an electrically driven liquid lens unit provided at the rear of the optical system to control the refraction of light passing through; a model eye having a multifocal intraocular lens on which light transmitting through the electrically driven liquid lens unit is incident; a camera that captures light transmitted through the model eye; and a control unit that controls the electrically driven liquid lens unit to control the refractive index of the electrically driven liquid lens unit, and calculates a defocus curve by analyzing images captured through the camera.
