title: Visual performance in pseudophakia with standard and ultraviolet-absorbing intraocular lenses: a preliminary report.
abstract: There is currently considerably interest in the vulnerability of the pseudophakic eye ultraviolet light. Contrast sensitivity was measured in patients receiving UV-absorbing and standard posterior chamber intraocular lenses (IOLs) and in normal age-matched observers. The results suggest that in the relative short-term there is no difference in visual performance with either type of IOL. Modulation Transfer Function studies on 3 batches of IOLs (2 standard and 1 UV-absorbing) showed slight variations in optical performance within and between batches. Spectral sensitivity testing demonstrated increased macular protection from short wave-length blue light by the crystalline lens when compared with both types of IOL.
