[Extracapsular cataract extraction combined with the implantation of an intraocular lens (author's transl)].

Between 1973 and 1980 349 intraocular lenses were implanted after intracapsular and 470 after extracapsular cataract operation. The results and complications are evaluated: following intracapsular lens extraction a 4-loop Binkhorst lens (iris clip lens) was inserted in all cases. Following extracapsular cataract operation a 2-loop Binkhorst lens (iridocapsular lens) was implanted in 194, a 4-loop lens in 276 cases. The two complications occurring most frequently were an Irvine-Gass syndrome in 10% following intracapsular, and a disturbing secondary cataract necessitating a discision in 19% after extracapsular lens extraction. A dislocation-decentration of the pseudophakos was observed in some cases after extracapsular cataract operation. It is therefore recommended that the extracapsular be preferred to the intracapsular cataract extraction, that a 4-loop lens be implanted, secured by a transiridectomy suture, but that the haptic part of the intraocular lens should not be inserted in the capsular bag. It is of paramount importance, especially in young pseudophakic patients, to prescribe carefully an additional optical correction, preferably progressive glasses.
