EFFECTS OF TINTED INTRAOCULAR-LENS ON CONTRAST SENSITIVITY

We evaluated contrast sensitivity and glare in 64 pseudophakic eyes. A n ultraviolet-absorbing intraocular lens (IOL) was implanted in 32 eye s and a noncyanopsia yellow-tinted IOL was implanted in 32 eyes. The l atter lens was designed to effectively absorb light below a wave-lengt h of 500 nm. Contrast sensitivity was measured at a pupil diameter of 3 mm using an artificial pupil. The implanted yellow-tinted IOL showed improved contrast sensitivity in the middle spatial frequencies of 6 and 12 c/deg in photopic and mesopic vision. In addition, the yellow-t inted IOL decreased the effect of central glare on the contrast sensit ivity. Copyright (C) 1996 The College of Optometrists. Published by El sevier Science Ltd.
