Abstract:
Although the occurrence of iatrogenic light-induced retinal toxicity is beyond doubt, several issues remain to be studied further. These include conflicting reports regarding the wavelength of light that is most hazardous; what mechanism contributes more significantly in the pathogenesis of light-induced retinal toxicity-photochemical or photothermal; why does it occur in only some patients; and what is the protective role of UV absorbing chromophores in intraocular implants. Nevertheless, it is important for all ophthalmic surgeons to be aware of this complication and take measures that could decrease the risk of its occurrence.
