Abstract Body:

Purpose: To develop a technique to prevent incomplete caps during FLACS, which may tear out. 

Study Design: The technique was developed based upon the principles of rheology, and its success was observed in subsequent cases. 

Methods: After the femto rhexis creation, a highly viscous and cohesive OVD is injected through a small-bore cannula over the center of the casulorhexis, until the rhexis becomes concave. The OVD cannula is then used to progressively depress the perimeter of the rhexis x 360 degrees along its circumference, pulling gently towards the centre, to assure that it is free. 

Results: Since adopting this technique, no further incomplete caps have been seen. 

Conclusions: The OVD Central Press Technique works because depression of the centre of the rhexis causes it to extend centrally, if at all, and not peripherally
