Abstract Details

PURPOSE:To optimize the visualization of the posterior lens capsule during pars plana vitrectomy to prevent its injury during the procedure.


Patients were selected from the Kasr Al-Aini Cairo University Hospitals outpatient clinic of Ophthalmology, in the period from Jan 2012 till Jun 2013


This case-control study was conducted on 2 groups of patients. In group I (49 eyes), a few small air bubbles were allowed to pass through the infusion cannula and into the eye where they adhered to the posterior lens capsule, while in group II (control; 52 eyes), phacovitrectomy was carried out without air bubbles. The primary outcome measure was the integrity of the posterior lens capsule during vitrectomy.


In group I, the 49 vitrectomized eyes (100%), the posterior lens capsule was perfectly visualized and avoided during detachment of the anterior hyaloid face, during total vitrectomy and during vitreous base shaving. In group II, there was one eye with posterior capsule rupture and intraocular lens drop (1.9%).


Small air bubbles help perfect delineation of the posterior lens capsule during vitrectomy, avoiding its injury.
