Unlabelled:
We present a simplified modification to a technique for early or mild in-the-bag subluxation that avoids conjunctival and scleral incisions and minimizes intraocular manipulation. While the capsulorhexis edge is grasped with an intraocular forceps to stabilize the IOL-capsular bag complex, a 10-0 polypropylene suture on a long curved needle is used to secure the fibrotic superior capsulorhexis edge to the midperipheral iris at 12 o'clock using a combination of a modified McCannel suture and a Siepser sliding knot.
