ENDOSCOPE-ASSISTED TRANSSCLERAL SUTURE FIXATION OF INTRAOCULAR LENSES

We describe a new method for placing transscleral sutures when fixatin g posterior chamber intraocular lenses to the sulcus. An intraocular m icroendoscope with an 18 gauge probe is used for direct sulcus observa tion and needle position assessment. The straight needle of a 10-0 pol ypropylene suture and the tip of the probe are placed in a 16 gauge si licone rubber tube to hold them together. Fixing the needle to the end oscope allows a direct view of its tip and requires only one hand. The other hand is used to grasp the tip of the needle when it comes out u nder the scleral flap after passing through the sulcus. Assessment of needle position with an endoscope avoids surgically induced iris root or ciliary body damage. Fixing the needle to the endoscope simplifies the surgical technique.
