First Experience with VERUS

  Channels: Cataract Surgery | Posted 4/22/2015

Aaron Waite, MD, shows his first experience with the VERUS ophthalmic caliper. The VERUS device fits into the standard cataract procedure flow and concludes with a well centered and round 5mm capsulotomy.

Steps to successful use of VERUS (basics for first cases):
1) Create incisions and 3/4 fill eye with a dispersive VE (Viscoat has been best in my hands. Don't use cohesive).

2) Insert VERUS through main wound using Y hook, Kuglen, Duets or similar device, place over anterior capsule surface and tap the device down to ensure it is secure on the capsule. (Duets work great for both insertion and removal but Utratas are fine too.)

3) Enter eye with dispersive VE cannula and tap down on VERUS every 1-2 clock hours while injecting over the VERUS pushing it against the capsule for stability and proper creation of a CCC and simultaneously filling the entire anterior chamber. This step is key because the complete filling of the AC locks the device down.

4) Use the cystotome or forceps to start the rhexis. The initial anterior capsular flap should not be guided directly to the inner edge of VERUS, rather, the flap should be kept short of the inner rim by 1-2mm and then lifted by forceps and walked tangentially to the inner rim while maintaining a vertical orientation along the inner rim of VERUS.

5) Use Duet forceps or other capsulorhexis forceps to grab the capsule and walk along the inner rim of VERUS while keeping the capsule vertically oriented against the device for 360 degrees.

6) Remove VERUS with a Sinskey hook or capsulorhexis forceps.

7) Complete cataract surgery as per routine.
