Abstract

Purpose : To evaluate the quality of the image of a grating target placed in a model eye viewed through extended depth of focus (EDOF) intraocular lenses (IOLs).

Methods : EDOF (Symfony®,ZXR00V), diffractivemultifocal (ZLB00 +3.25D or +4.0D) or monofocal (ZCB00V) IOLs of +20.0D were placed in a fluid-filled model eye with human corneal aberrations. A United States Air Force Resolution Target was placed on the posterior surface of the model eye and was viewed through a flat contact lens, a wide-angle contact lens, or non-contact wide-angle viewing system (60D or 128D, Resight, Carl Zeiss). The contrasts of the gratings were evaluated under chandelier illumination and compared to those obtained through a monofocal IOL.

Results : The grating images viewed through flat contact lens were slightly defocused through the ZXR00V IOL. The images observed through the central area of the ZLB00 with flat contact lens were defocused and the images in the periphery were very blurred. The contrast of the images viewed through ZXR00V and ZLB00 IOLs with flat contact lens decreased significantly in low frequencies (P<0.01) comparing to that of the monofocal IOL. The contrast of the images viewed through ZXR00V and ZLB00 IOLs with wide-angle contact lens and wide-angle viewing system was not significant except the contrast with wide-angle viewing system by 60D lens in low frequencies (P<0.01).

Conclusions : EDOF IOL decreases the contrast of the grating target viewed through flat contact lens comparing to the monofocal IOL but have better contrast than multifocal IOLs. This difference of the contrast decreased in the images viewed through wide-angle contact lens and wide-angle viewing system.
