[Cost effectiveness evaluation of cataract patient care in respect of monofocal intraocular lenses from the perspective of German statutory health insurance].

[Implantation of an ARTISANtrade mark toric phakic intraocular lens to correct high astigmatism after penetrating keratoplasty].

Background: Visual outcome after penetrating keratoplasty is often Iimited by residual astigmatism.
