Abstract

Objective To evaluate the contrast sensitivity and color vision of the yellow colored UVCY Intraocular Len (IOL). This new IOL can reduce the absorption of UV and short-wave length (400–500nm) visible light by adding UV blocking material and yellow coloring dye to ordinary PMMA. Methods ECCE and UVCY IOL implantation were performed for the senile cataract patients in 30 eyes, and the UV-IOL in 36 eyes. Visual acuity, contrast sensitivity measured by SINE WAVE CONTRAST TEST of Stereo Optical Co. and FM-100 color vision were examined at l week, 1 month, 3 months, 6 months after operation respectively. Results The contrast sensitivity and color vision of the patients normalized after they had been performed ECCE and IOL implantation. The yellow colored UVCY-IOL showed significant higher values than ordinary UV-IOL in the low and medial frequency in spatial contrast sensitivity and was above the normal people's level. The subjective sensation was better than UV-IOL in the early postoperative period. Conclusion the yellow colored UVCY-IOL is better than ordinary IOL in spatial contrast sensitivity. Its subjective sensation is also good in the early postoperative period.
