Abstract
PURPOSE: To describe the use of FLACS (Femtosecond-Laser-Assisted Cataract Surgery) and pupiloplasty technique employed in a cataract surgery associated with iris-lens-zonule coloboma, as well as to report the advantages that FLACS can provide in this type of complicated surgery. OBSERVATIONS: During FLACS (Victus® - TECHNOLAS, Bausch and Lomb Incorporated, USA), after the docking procedure, the parameters of capsulotomy, fragmentation and incisions were manually adjusted. Iris retractors were anchored to the edge of the anterior lens capsule to provide stability to the bag during phacoemulsification maneuvers, and a capsular tension ring and intraocular lens (IOL) were implanted. Iris repair was approached using a modification of the slip-knot technique. For this purpose, a 10.0 Prolene on a straight needle was used and knotted extraocularly, over the conjunctiva. Finally, an anterior vitrectomy was performed as a precaution. CONCLUSIONS AND IMPORTANCE: In spite of the existing controversy regarding FLACS technology compared to conventional surgery, it seems to be beneficial in complicated cases such as cataracts associated with iris and lens coloboma, since it allows the modification of different parameters that facilitate and ensure surgery safety. On the other hand, the iris repair technique described facilitates manipulation of the iris sutures. In addition, complementary techniques such as the use of a capsular tension ring and pupiloplasty help to center and stabilize the IOL, and to reduce the symptoms derived from iris coloboma, obtaining a better visual quality.
