Preserflo® Microshunt* Glaucoma Surgery (Post-op 4 weeks)

With CASIA2 it is possible to identify the presence of fluid spreading out through the tissues, leading to multilayered conjunctiva. This sign has been reported to be a surgical success factor when it is detected in the early postoperative period. In terms of safety, one of the key points of this device is its relation with the anterior chamber structures after implantation, in particular with the corneal ­endothelium. CASIA2’s calipre tool can be used to measure the distance from the tube to the endothelium and to the iris, as well as the total length of the tube inside the anterior chamber (from its exit throughout the irido-corneal angle).

Anterior Segment Optical Coherence Tomography has been demonstrated to be a useful tool in the postoperative assessment of multiple glaucoma surgeries. This may be particularly relevant in bleb-forming techniques and in those procedures dependent of implants or other devices. In this user experience, several cases of different glaucoma surgeries are presented showing the improved imaging performance of CASIA2 and its utility.
