Comparison of color perception after tinted blue light-filtering and clear ultraviolet-filtering intraocular lens implantation.

摘要

PURPOSE: To compare color perception after implantation of clear and yellow-tinted intraocular lenses (IOLs). SETTING: Dr. Rajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi, India. DESIGN: Comparative case series. METHODS: This study evaluated eyes that had implantation of an Acrysof IQ SN60WF yellow-tinted IOL or an Acrysof SA60AT clear IOL. All eyes were evaluated postoperatively at 1 month and 3 months. The uncorrected distance visual acuity, intraocular pressure, and color vision (Ishihara pseudoisochromatic test, Edridge-Green lantern test, Heidelberg anomaloscope, and Farnsworth-Munsell (FM) 100-hue test) were evaluated. RESULTS: Both IOL groups comprised 50 eyes. There were no significant differences between the 2 groups in color vision on any of the 4 tests (P>/=.05). Plotting the error scores on the polarity graph of the FM 100-hue test showed that eyes with a yellow-tinted IOL did not have a specific axis of confusion. CONCLUSION: There was no difference in color perception between the 2 IOLs irrespective of the color vision test used.
