PATIENT INFORMATION: Eye Implants
What … for? (Indications)
Intraocular Lenses (IOL)
– Anterior chamber lenses
Phakic (remaining natural lens). Refractive lenses are used for myopia, presbyopia and high hyperopia, if laser or corrective lens treatment is not done.
– Posterior chamber lenses
Aphakic (no lens). Used at cataract, the replacement of the natural lens.
Glaucoma Filtration Device
Glaucoma filtration devices are used to control intraocular pressure (IOP), at previously failed trabeculectomy, at insufficient conjunctiva, scarring and complicated glaucomas.
Partial or complete aniridia
Capsular tension ring
– Diplopia Implant
– Pupil Dilator
– Implants for Children
Global 19Mio 2010, 19.7Mio 2012 IOL
Cataracts account for 48% of world blindness.
Germany: 650.000 Cataract surgeries/year
Recovery from the procedure is usually within 24 hours.
(some may be relative)
Specific job requirements (e.g. pilot, public service vehicle). Night vision important. Low change of myopia.
Retinitis pigmentosa. Stargardt disease. Macular diseases. Any abnormality of the optic nerv. Fuchs corneal dystrophy. Macular degeneration. Diabetes mellitus.
No improvement, infection (0.03-0.05%), rotation of the lens, lose of vision.
Secondary cataract (0.6%), yearly loss of 1.8% of the endothelial cells, retinal detachment, corneal swelling (0.4%). Glaucoma, Glare, Halo (FDA)
Loss of accommodation, minimized with multifocal lenses (slight double vision, reduced contrast), difficulty with performing tasks like driving at night or in fog.
Mechanical trauma, infection, optical problems

Cornea Implants, Cornearing
Glaucoma Filtration Device, valved/nonvalved
Stainless steel, Acrylics
Antenna, electronic case, electrode array
No longterm studies with appropriate numbers available.
