The Zepto® Precision Cataract Surgery System provides high quality anterior capsulotomies during cataract surgery. Follow a few simple instructions to achieve perfection consistently.
- Inspect the capsulotomy tip, make sure the push rod is not dislodged from the nitinol capsulotomy ring. Remove any foreign material that may be attached to the ring.
- Extend the finger slider forward to elongate the tip until a ‘click’ is heard.
- Insert the elongated Zepto tip through the corneal incision. A 2.2mm or larger incision may be used. OVD may be placed at the entrance of the incision to facilitate Zepto tip entry.
- Stabilize the eye using a Thornton ring or a second instrument placed through the sideport.
- Once Zepto is in the anterior chamber, retract the push rod using the finger slider to –re-circularize Zepto.
- Leave the tip of the push rod tip at a position just outside the capsulotomy ring. This allows the push rod to remain in the neck of the device facilitating positioning Zepto for capsulotomy.
- Once capsulotomy position is achieved, the surgeon calls for ”SUCTION”, and the circulating assistant pushes the “SUCTION” button on the control console.
- As suction is applied, the push rod must be retracted fully to the wide portion of the Zepto neck, allowing the suction cup to drop vertically onto the capsule. FULL SUCTION WILL NOT DEVELOP IF THE PUSH ROD IS LEFT IN THE NECK AND A PARTIAL CAPSULOTOMY OR A WEAKER CAPSULOTOMY MAY RESULT.
- Monitor the flow of bubbles visually during suction. When the flow has ceased, the surgeon calls for ‘ENERGY”, and the circulating assistant pushes the “CUT/RELEASE” button on the control console. IF THE FLOW OF BUBBLES HAS NOT CEASED BEFORE ENERGY IS APPLIED, FULL SUCTION MAY NOT HAVE DEVELOPED AND A PARTIAL CAPSULOTOMY OR A WEAKER CAPSULOTOMY MAY RESULT.
