ABSTRACT
AIM: To evaluate the preservation of anterior capsule during vitrectomy and lensectomy.ment (RD) and grade C proliferative vitreoretinopathy (PVR)underwent pars plana vitrectomy (PPV) and pars plana lensectomy (PPL) with preservation and polishing of the anterior capsule. Of the 15 eyes, 4 eyes had giant tear, 3 had recurrent rhegmatogenous retinal detachment (RRD), 2 had diabetic retinopathy. Totally 6 eyes had gas and 9 had silicone oil tamponade. The surgeries were evaluated according to the visual acuity (VA) and the postoperative complications during the follow-up of at least 3 months.in all eyes, improved by 3± 3 lines overall. Eight eyes were implanted posterior chamber intraocular lens (PCIOL) successfully at 2-3 months after operation, including 6 having gas and 2 having silicone oil tamponade. No eyes had central anterior capsule opacity, corneal decompensation, puplillary block, retina redetachment or other complications.an intact anterior capsule in eyes with RD and PVR. Preserving the anterior capsule can help preventing intraoperative and postoperative complications of gas or silicone oil, simplify future PCIOL placement, and maintaining a normal iris appearance.
ABSTRACT
We evaluated after-cataract, capsular opacification, following combined lens removal with phacoemulsification or pars plana lensectomy, pars plana vitrectomy and primary or secondary IOL implantation on 34 eyes followed up more than 3 years.For the lens removal 23 eyes had pars plana lensectomy ad 11 eyes phacoemulsification. Nd-YAG capsulotomy is needed on 8/34 eyes(25.5%). Nd-YAG capsulotomy was performed on 3/23 eyes(13%) of pars plana lensectomy and on 5/11 eyes(45.5%) of phacoemulsification. Nd-YAG capsulotomy was performed to 7/22 eyes(31.8%) of primary IOL implantation and 1/12 eyes(8.3%) of secondary IOL implantation. Most patients had systemic vascular disease such as diabetes or hypertension.In conclusion, combined pars plana lensectomy, pars plana vitrectomy and secondary IOL implantation was the least incidence of after-cataract and side effects, so this procedure was thought to be recommended for vitreoretinal surgery.

Many patients present simultaneously with visually significant (to the patient and surgeon) lens opacities and vitreoretional disease. Traditional management of this problem has included two operations: vitrectomy followed by cataract extraction or cataract extraction followed by vitrectomy. Visual rehabilitation of aphakic eyes after pars plana vitrectomy is often difficult when anatomic objectives are achieved. Intraocular lens provides more natural and convenient vision. Now, simultaneous cataract extraction and lens implantation during pars plana vitrectomy can be considered. We performed posterior chamber lens insertion in the ciliary sulcus after completion of pars plana lensectomy, vitrectomy, and removal of intraocular foreign body. During pars plana lensectomy, we left the anterior lens capsule and zonules intact. After posterior chamber lens insertion, we removed the central anterior lens capsules from behind the optical component leaving a peripheral rim to support the haptics. The procedure provided good pseudophakic vision.
