Abstract

PURPOSE
To compare contrast sensitivity and color vision after implantation of a clear intraocular lens (IOL) and a yellow-tinted IOL in diabetic retinopathy patients. METHODS: In the 50 eyes of 25 diabetic patients with non-proliferative diabetic retinopathy, clear IOLs were implanted in 25 eyes, and yellow-tinted IOLs were implanted in 25 fellow eyes. Three months after the surgery, contrast sensitivity function was measured with a vision contrast test system, and color discrimination was tested using the Farnsworth Munsell 100-hue test. RESULTS: Eyes implanted with yellow-tinted IOLs had significant differences in contrast sensitivity values compared to those of fellow eyes implanted with clear IOLs in both the moderate diabetic retinopathy group (6.0 cycles per degree) and the severe diabetic retinopathy group (throughout all spatial frequencies except 12.0 cycles per degree). The yellow-tinted IOL did not modify chromatic discrimination compared with that of the clear IOL. In the blue-yellow axis error score, however, there were significant differences between the clear IOL and the yellow-tinted IOL. CONCLUSIONS: With progressing diabetic retinopathy, the yellow-tinted IOL provided better contrast sensitivity than the clear IOL. The yellow-tinted IOL improved color vision in the blue-yellow chromatic axis without causing chromatic discrimination defects.
