ABSTRACT
·

AIM:

To inspect and compare the functional vision of an aspheric intraocular lens (Tecnis) with those of conventional monofocal silicone and acrylic intraocular lens and multifocal intraocular lens (Array).·

METHODS:

The IOLs were tested in the eye model, which was designed to be optically equivalent to the theoretical eye model. The eye model is a combination of a spherical photographic lens with 35mm focal length ( IOL put in a water cell)and a charge coupled device (CCD) camera. The images constructed by the lenses are observed on a monitor of personal computer and the contrasts of the images are analyzed by using commercial image processing software

RESULTS:

The modulation transfer function of the eye model equals the scale produced by the theoretical eye model. The images constructed by changing the diameter of aperture stop and IOL.·

CONCLUSION:

The proposed eye model is useful for testing functional vision and for inspecting differences of intraocular lens.
