[Clinical observation on pars plana lensectomy-vitrectomy preserving lens anterior capsule]

To investigate the therapeutic effect of combined operation on cataract complicated with vitreous pathology.

19 patients (20 eyes) with coexisting cataract and vitreous opacification or endophthalmitis or intraocular foreign bodies were operated with pars plana lensectomy-vitrectomy preserving lens anterior capsule. The ciliary sulcus intraocular lenses (IOLs) were primarily implanted for sixteen eyes of 19 cases in the operation.

All cases were followed up for 12-36 months. Visual acuities of 18 cases were improved, 7 eyes between 0.3-0.5, 11 eyes beyond 0.5, the best one at 1.2. Anterior capsule opacification occurred merely in one eye, and in others the capsule kept being transparent.

Preserving anterior lens capsule in the operation is beneficial to the insertion of IOL, and the anterior segment is affected slightly, thus it is a promising method for treating cataract complicated with vitreous opacification.
