Abstract Details

Purpose:

In this study, we examine the influence of ionizing radiation on the optical properties of the intraocular lenses (IOLs). The factors that affect the postoperative “life” of the IOL causing cloudiness or discoloration have no be yet fully clarified. The results of the IOLs exposure to X-rays through interventional radiology and cardiology procedures are investigated.

Setting:

All the authors have no conflict of interest.

Methods:

Yellow azo-dye IOLs made from an acrylate/methacrylate copolymer were irradiated with x-rays at clinical doses. Undoped hydrophobic acrylic IOL made from acrylate/ methacrylate copolymer were used as control. The transmittance of the IOLs was measured pre-irradiation and post-irradiation by using a spectralon-coated integration sphere and a UV/Visible spectrometer.

Results:

The transmission spectra of the IOL pre- and post-irradiation indicate that in the UV-VIS spectrum region the IOLs show an increase in the transmittance with a highest change equal to 35%. In the residual spectrum the transmittance is decreased by average percentage of 4%, respectively.

Conclusions:

The results indicate that the transparency of the IOLs change after the exposure to X-ray radiation even at low clinical doses. The UV-blue light protection filter against the harmful for the retina UV radiation and short wavelength blue right is decreased.
