Title

FRO - Investigating the influence of light intensity and wavelength on retinal straylight

Purpose	To study the influence of macular pigmentation and yellow intraocular lenses (IOLs), promoted with the argument that by blocking blue and ultraviolet light the retina would be protected. Moreover the influence of the yellow lenses on color vision is studied as well.
Methods	For this study a cohort of 100 patients diagnosed with bilateral cataract, is divided into four subgroups of 25 patients each. The patients in these groups will be bilaterally implanted with respectively two colorless Bag-in-the-Lens IOLs (BiL), two yellow BiL IOLs, two colorless AcrySof SA60AT IOLs or two yellow AcrySof SN60AT IOLs . Patients with prior ocular surgery, retinal defects or glaucoma will be excluded from this study. Three months after surgery of both eyes patients perform a straylight test using the Oculus C-Quant straylight meter, a color vision test with the City Occupational CAD test and the macular pigment test with the Tinsley QuantifEYE (MPOD) device.
Results	This project has recently started the recruitment phase and so far a number of subjects have agreed to participate. These patients will soon be bilaterally implanted with the IOL type of their respective group. The first follow-up tests on these patients will be performed shortly.
Conclusion	This study is progress and we hope to present the results at the 2011 OB congress.
