Abstract Details

Purpose:

Measuring number and shape of endothelial cells after phacoemulsification using an anterior capsule rhexis flap for endothelial cell protection.

Setting:

Vienna Institute for Ocular Surgery (VIROS), a Karl-Landsteiner institute, Hanusch Hospital, Vienna, Austria

Methods:

Cataract patients scheduled for surgery (LOCSII >2) were included in this prospective study. The anterior capsule flap from the capsulorhexis was pushed against the endothelium using ophthalmic viscoelastic substance and, hence, used as an endothelial protection shield during phacoemulsification (as mentioned by G. La Rocca et al. (Italy)). During surgery, continuous intra-operative optical coherence tomography (ReScan700, Carl Zeiss Meditec AG) recordings were performed to verify the position of the anterior capsule flap. Endothelial cell density was measured pre-operatively and two months post-operatively. Additionally, central corneal thickness was measured pre-operatively, one hour, one day and two months after cataract surgery.

Results:

: Sixty eyes of 60 patients were recruited. First attempts showed an existence of a learning curve to maintain the flap during the whole phacoemulsification but after few tries the precodure could be attempted with a good feasibility. Further data as well as the success rate of the novel technique will be presented at the meeting.

Conclusions:

Swirling lens fragments are a risk factor for the endothelium. Novel techniques to protect the endothelium are promising.
