Finally, the retinal break is repaired with cryotherapy or laser.Īlthough there is evidence about the effectiveness of these techniques separately in pseudophakic retinal detachments, it is not clear whether the combination of scleral buckling with pars plana vitrectomy is superior in patients with an artificial lens (pseudophakic) or patients without an intraocular lens (aphakic). In scleral buckle, the surgeon sutures a silicone implant to the outer surface of the sclera creating an indentation in the wall of the eye to achieve the apposition of the neurosensory retina and retinal pigment epithelium. Pars plana vitrectomy consists in the removal of vitreous gel associated with laser and injection of gas or silicone oil to compress the retina. Pars plana vitrectomy and scleral buckle (or encircling band) are two surgical procedures employed to repair retinal detachments. Cataract surgery, an intervention that aims to replace the natural lens by an artificial lens (pseudophakia), could increase the risk of retinal detachment by a factor of seven to eight times.

Rhegmatogenous retinal detachment is defined as the separation of the neurosensory retina from the underlying retinal pigment epithelium. In terms of surgery complications, we are uncertain if vitrecto-my plus scleral buckle increases the risk of proliferative vitreoretinopathy or reduces the risk of glaucoma because the certainty of the evidence is very low. With this data, we conclud-ed that pars plana vitrectomy plus scleral buckle may make little or no difference in primary or final retinal reattachment rate nor in final visual acuity, but the certainty of the evidence is low. We identified four systematic reviews with eight studies overall, one of them was a randomized trial. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. The combination of both techniques had been proposed for rhegmatogenous retinal detachment in patients with previous cataract surgery (pseudophakic or aphakic), but its effectiveness remains unclear.

Pars plana vitrectomy and scleral buckling are two surgical procedures used for its repair. Cataract surgery increases the risk for rhegmatogenous retinal detachment.
