Abstract Details

Purpose:

Posterior capsule opacification (PCO) is still the most frequent long-term complication of modern cataract surgery and leads to significantly reduced visual acuity in many patients. We describe a new technique for performing a primary posterior laser-assisted capsulotomy (PLC) after IOL implantation to prevent posterior capsule opacification.

Setting:

Ruhr University Eye Clinic, Bochum, Germany

Methods:

After IOL implantation, a thin layer of OVD was injected between the IOL optic and the posterior capsule. After sterile re-docking to the laser system, the IOL-optic, OVD-layer, the posterior capsule and Berger’s space were identified using 3D SD OCT. The treatment zone was positioned on the posterior capsule. The IOL-optic was always outside the treatment zone.

Results:

Fifty-five patients were re-docked after IOL implantation. In all cases, no sutures were necessary to re-dock the eye after laser cataract surgery and no wound leaks were observed. In 8 cases (4%), the OCT was not able to visualize the posterior capsule after IOL implantation and no PLC was performed. In 8 cases (15%), the posterior capsule was connected to the anterior hyaloid surface as interpreted from the OCT. In 45 of these 55 cases (81%), the posterior capsule was located and identified between the posterior surface of the IOL and the anterior hyaloid membrane. In all treated PLC cases, a 360° cut was successfully accomplished. In none of the cases the IOL optic was damaged by the laser.

Conclusions:

Due to a relatively large Berger’s space intraoperatively, which we detected in a large proportion of our patients, the described techniques for PLC has the potential to prevent and solve posterior capsule opacification in routine cases.
