Among 331 cataract extractions with IOL implantation performed May 1988-Jan. 1992, 33 (10%) were complicated with posterior capsule rupture and vitreous loss occurred in 16 eyes (4.8%). After vitrectomy with scissors and sponge, in-the-bag implantation was performed in 3 eyes, sulcus-fixed lenses in 24 eyes, and anterior chamber lenses in 6 eyes. 32 eyes (97%) gained visual acuity of 0.5 or better during follow-ups of 5 months to 4 years, indicating that with careful anterior vitrectomy and proper modality of IOL implantation, good visual results could be achieved.
