AVH HOLDER – Anterior vitrectomy holder

PRODUCT NUMBER 1677

The Advanced Cataract/Anterior Vitrectomy Holder (AVH) allows for simulation of cataract surgery and its complications when used with Bioniko OKULO anterior segment models

Use with an OKULO BR8 anterior segment and a cataract lens to perform capsulorhexis, phaco, anterior vitrectomy and scleral fixated IOL in a single setup.

Compatible with ROMANO head

CASES AND PATHOLOGIES

VITREOUS LOSS SCENARIO (ANTERIOR VITRECTOMY): There are two ways to simulate an Anterior Vitrectomy scenario: One, right after performing a phacosimulation with our cataract lens, and the second option, skipping the phaco and starting the anterior vitrectomy scenario with an empty bag lens.
  • CATARACT LENS: Insert an OKULO BR8 anterior segment with cataract lens as described above; perform the cataract simulation normally until you have an empty capsular bag. If posterior capsule is still intact (good job!),create a PCR with the energized phaco hand-piece or with your second instrument. Make sure the rupture is large (3-4mm) so that vitreous can easily flow anteriorly. Slowly inject vitreous substitute with the syringe connected to the port.
  • EMPTY BAG: Create a PCR on the empty bag posterior capsule. Make sure the rupture is large (3-4mm) so that vitreous can easily flow anteriorly. Attach the empty bag to an OKULO BR8 anterior segment. Insert the pre-assembled segment and len sin the prepared AVH as described above; create the main incision and paracentesis in the cornea. Slowly inject vitreous substitute with the syringe connected to the port. After the Vitreous is in the anterior chamber, proceed to perform the Anterior Vitrectomy technique as guided by your faculty. To repeat the scenario, simply inject more vitreous with the syringeand start over.

CHARACTERISTICS

KEY FEATURES:
  • The holder features a vitreouscavity that can be filled with vitreous substitute through a port using a standard syringe (5cc recommended). The soft seal mates with the OKULO anterior segment model when inserted in the holder, allowing for vitreous loss to be controlled via the syringewhen a rupture is made in the posterior capsule of a cataract lens or an empty bag lens.
  • As with all BIONIKO holders, the AVH has flexible neck to simulate natural eye movement and is coupled to a suction cup for fixation to any flat surface.
  • The release tab is used to remove the AVH from the surface. The raised lip feature allows fluid pooling, mitigating the ingress of bubbles when using instruments with high rates of aspiration during phaco or vitrectomy. The AVH also features a 0.6mm punctum feature.
INSTRUCTIONS FOR USE: INSERT AN OKULO ANTERIOR SEGMENT:
  1. Place AVH on a smooth surface and press down to engage suction
  2. Connect a syringe filled with vitreous substitute (egg whites are a good option)
  3. Add DISPERSIVE viscoelastic around the soft seal
  4. Fill the vitreous cavity up to the seal margin by slowly pressing on the syringe
  5. Slide the anterior segment under the eyelid and over the soft seal into place. Do not compress the OKULO model while engaging to the holder, but rather gently peel the holder eyelid until eye model seats properly
  6. Press the anterior segment down to confirm proper seating of the anterior segment and to create a coupling with the seal
  7. Wait 5 minutes for visco-seal to set
DISASSEMBLY:
  • Remove ANTERIOR SEGMENT by leveraging out with a blunt object through either “corner” of the eye. DO NOT PULL ON HOLDER BODY TO RELEASE. Lift the suction release tab to remove the AVH from surface.
