Abstract: 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.

Abstract: A slit lamp microscope may include first and second arms rotatably provided on a main shaft; a microscope provided on the first arm and used to observe a subject's eyeball; a light source unit provided on the second arm and irradiating light including near-ultraviolet and visible light regions, including light with a wavelength of 405 nm, to the eyeball of a subject; a third arm rotatably provided on the main shaft; a camera provided on the main shaft and imaging the eyeball of the subject; an excitation filter that transmits only light with a wavelength of 405 nm that induces a fluorescence reaction in stained goblet cells among the light irradiated from the light source unit to the eyeball of the subject; and a light receiving filter that transmits only the light fluorescently reacted in the goblet cells among the light received by the camera.

Abstract: Disclosed is a defocus curve measuring apparatus for a multifocal intraocular lens capable of automatically measuring an objective defocus curve. A defocus curve measuring apparatus for a multifocal intraocular lens according to an aspect of the present invention may include a light source passed through a target image for focusing; a first lens that infinitely refracts the focus as the light source passes through it; a beam splitter having a polarization function that passes p-polarized light of the light source that has passed through the first lens and reflects s-polarized light; an intraocular lens module that refracts the light source that has passed through the beam splitter as it passes, thereby determining the focus; and a camera that captures an image of s-polarized light reflected by the beam splitter after the light source reflected from a retina passes through the intraocular lens module.

Abstract: 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.

Abstract: A multilayer cornea harvesting apparatus capable of obtaining layers of cornea from one cornea enucleation object and a cornea harvesting method is disclosed. The apparatus includes a base supported on a bottom surface, a mount detachably coupled to the base, allowing a cornea enucleation object to be placed thereon, having a first opening part formed at a portion corresponding to the cornea of the cornea enucleation object, and having a first medicinal fluid charging space formed between the base and the mount, a stabilizer fixing, to the mount, a sclera portion of the cornea enucleation object placed on the mount and having a second opening part formed at a portion corresponding to the cornea, and an upper cover detachably provided on the upper side of the cornea, supported by the mount or supporting the mount, and forming a second medicinal fluid charging space on the upper side of the cornea.

Abstract: Disclosed is a model eye apparatus by which patients can wear an intraocular lens in reality before a surgery and experience an image that the patients will actually see after the surgery. A wearable model eye apparatus according to the present invention comprises: a plurality of guide members arranged in parallel; an intraocular lens module which is installed to be movable forward or backward by guidance of the plurality of guide members and has an intraocular lens installed therein; and a minus lens module which is installed in front of the intraocular lens module to be movable forward or backward by guidance of the plurality of guide members and has a minus lens disposed therein.
