Douglas Clarkson takes a look at how the increasing body of evidence for light toxicity effects on the retina have influenced the design of intraocular lenses
Intraocular lenses (IOLs) remain something of a relatively recent innovation in ophthalmology, with uptake of such lenses not really taking off until the mid-1970s with the introduction of cataract extraction techniques of phacoemulsification. It was around 1978 that the first reports were made by Mainster1 linking intraocular lenses with photic retinopathy.
