[The investigation with contrast sensitivity after implantation with UV and UVCY types of intraocular lens].
OBJECTIVE
To research the difference in vision after UV and UVCY two types of intraocular lens implantation (The light 380-790 nm may transmit through the UV lens, and the UVCY lens may partly filter the light < 640 nm including part of the light < 460 nm.).


METHODS
MCT 8000 contrast tester was used in the postoperative two months.


RESULTS
The contrast sensitivity of the patients with UVCY lenses was superior to that with UV lenses obviously (P < 0.05) under the condition of glare and 3 c/d, 6 c/d space frequency.


CONCLUSIONS
The UVCY lens is more advantageous to improve visual function.
