We describe a new method for placing transscleral sutures when fixating posterior chamber intraocular lenses to the sulcus. An intraocular microendoscope with an 18 gauge probe is used for direct sulcus observation and needle position assessment. The straight needle of a 10-0 polypropylene suture and the tip of the probe are placed in a 16 gauge silicone rubber tube to hold them together. Fixing the needle to the endoscope 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 under 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.
