Abstract
Non-corrected residual refractive errors after cataract extraction and implantation of an artificial intraocular lens (IOL) lead to limited visual acuity or suboptimal usage of enhanced optical properties of IOLs, such as bifocal implants, which are dependent on postoperative emmetropia. In addition to the established corneal procedures for correction of ametropia (excimer laser surgery or limbal relaxing incisions) sulcus supported pseudophakic supplementary IOLs can also be implanted. These IOLs have been designed to deal with the problem associated with sulcus implantation, such as pigment dispersion glaucoma, intralenticular opacification or iris capture. Other possible fields of application of these lenses are the correction of higher astigmatism after any form of keratoplasty in pseudophakic eyes, reversible presbyopia correction by implementing bifocal optics or reversible, bulbus growth-adjusted treatment of ametropia in pediatric cataract surgery.
