Purpose:
To analyze effects of the composition and the color of intraocular lenses (IOLs) on laser wavelength.
Design:
A case control study.
Method:
Laser light rays at wavelengths ranging from 0.1 to 0.5 W were directed at a polymethymethacrylate ocular model fitted consecutively with three types of IOLs at various refractive powers. A laser detector was placed on the model beneath the lenses. The laser beam was passed through the IOLs and the output measured by a sensor. Attenuation rate was calculated.
Results:
The colored IOL caused significantly more attenuation than did the noncolored IOLs (p <.01). A 30-diopter colored IOL showed an attenuation rate of up to 15% at a wavelength of 488 + 514 nm.
Conclusions:
Consideration of the wavelength and the output of a laser for a particular IOL is required when laser photocoagulation of the retina is performed in patients with pseudophakia.
