Most frequent questions and answers

During trabeculectomy, it is convenient to inject the required quantity to lift up the scleral flap sufficiently and to put the sutures under tension. Healaflow shall be placed with care respecting a security distance so as to avoid any risk of involuntary gel injecting into the anterior chamber through the trephination. Any injection under the conjunctiva shall be performed at a safe distance from the limbus, making sure the conjunctival is properly secured (rigorous water tightness). This will help in preventing any risk of postoperative Seidel/bleb leakage.

During deep sclerectomy, the scleral space has to be completely filled with Healaflow, notwithstanding the number of sutures used to tighten the scleral flap. If any injection under the conjunctiva is required, this should follow the same procedure as for trabeculectomy. 

In association with the implementation of shunts, stent or tube, Healaflow can be used to fill-up the conjunctiva bleb reasonably.

Cross-linked sodium hyaluronate is not toxic for ocular tissues, including those of the anterior chambers. In addition, the nature of this implant (a cross-linked gel, thus endowed  with a «compact» structure) considerably limits the risk of gel migration into the anterior chamber.

Nevertheless, should the gel be unexpectedly present in the anterior chamber during or after surgery (detected through a deepening of the anterior chamber and slight concavity of the iris), this would require removal of the gel to avoid hypertension risk.

 The combination of Healaflow and Mitomycin is routinely used to create a synergical action. Indeed, Healaflow is dedicated to long-term preservation of the filtering space. On the other hand it cannot fully control the fibrosis process especially for patients at risk. Thus, Healaflow can be used for keeping the filtering bleb open or acting in the regulation of the aqueous humour outflow. The combination between the structural properties of Healaflow and the pharmacological action of Mitomycin C is beneficial and synergetic.
