title: [Intraocular Lens as a Drug Delivery Device: State of the Art and Future Perspective].
abstract: Development of an intraocular lens (IOL) as a drug delivery device has been pursued for many years and is a promising concept in modern cataract surgery. Common postoperative conditions such as posterior capsule opacification (PCO), intraocular inflammation or the rare but severe complications of cataract surgery like endophthalmitis are potential therapeutic targets for a drug-eluting IOL. There are three techniques of pharmacological IOL modification: Firstly, surface modification of the IOL ("coating"); secondly, IOL optic modification ("soaking") and lastly, loading the IOL haptics with a slow release system. The last option does not interfere with the IOL optics at all. Therefore, a broad spectrum of pharmacological agents needs to be assessed in preclinical and clinical studies to determine which agent/IOL combination is safe and efficient. For pharmacological PCO prophylaxis, erufosine-loaded IOLs are of great clinical interest. Heparin-coated IOLs might become clinically relevant for attenuation of intraocular inflammation after cataract surgery and cefuroxime-loaded IOLs for endophthalmitis prophylaxis.
