We read with interest the article by Gentile and Eliott describing silicone oil retention sutures for aphakic eyes with iris loss.1 This technique aims to create a physical barrier with polypropylene retention sutures that can prevent silicone oil prolapse into the anterior chamber and related complications.
This astute idea can be improved further by a simple modification to establish a uniplanar barrier against herniating silicone bubble. Bringing all the polypropylene sutures into a single plane can be accomplished by weaving the individually placed sutures into each other to form a net. For this purpose, the first 2 sets of vertical sutures are passed across the anterior chamber as described previously (Figure); however, the horizontal sutures are woven across the vertical threads by simply passing the 16-mm-long straight needle between vertical one. This way, woven polypropylene sutures (Figure) create a uniplanar net and increase their contact surface with the silicone bubble. Increased surface translates into decreased pressure at the silicone-suture interface and a lower chance for silicone to pass through the retention sutures.
