The authors evaluated the final functional results in 30 eyes where on account of nuclear and cortical cataract an intraocular lens was implanted. The operation was preceded by pars plana vitrectomy (PPV) with internal gas tamponade on account of an idiopathic macular hole (IMD). The cataract the development of which was recorded in 57 eyes was the manifestation of a late postoperative cmplication from a total number of 84 phakic eyes (67.9 %) which were operated on account of IMD between April 1996 and June 1999. After cataract surgery the corrected visual acuity improved in 23.3 % eyes. The investigation confirmed improvement and stabilization of the final corrected visual acuity in 24 eyes (80 %) and confirmed the importance of these surgical procedures.
