We always aim for a perfect case, but as every seasoned surgeon knows, it’s not about the complication, rather it’s about how you recover from it. Today we’re discussing a challenging scenario: a combined Phaco-PPV for a macular hole and while inserting a trocar, the sharp tip inadvertently punctures the posterior lens capsule. This is a “stop and think” moment. If you proceed with standard phacoemulsification, that small tear will quickly become a massive hole, and you’ll find the crystalline lens sitting on the macula. Here is how to handle a Trocar-Induced Posterior Capsule Rupture successfully.
The Management Strategy: Stability First
- Step 1: Don’t Panic and Don’t Hydrodissect. If you haven’t started the cataract portion yet, do not perform traditional hydrodissection. The fluid pressure will propagate the tear. Instead, perform hydrodelineation to stay away from the capsule and focus on a slow-motion phaco technique.
- Step 2: Scaffolding with Viscoelastic. Before you even touch the lens with the phaco probe, fill the area of the tear with a cohesive OVD. This creates a physical barrier that keeps the vitreous back and prevents lens fragments from falling into the vitreous cavity.
- Step 3: Management of the Nucleus. Use a low-flow setting and avoid any sudden changes in anterior chamber pressure that would allow the tear to expand.
- Step 4: The Vitrectomy Advantage. Since you are already set up for a PPV, you have the ultimate safety net. If any lens material starts to migrate posteriorly, do not chase it with the phaco tip, just switch to the vitrector
Converting to a Success
Pro-Tip: If the tear is peripheral and small, you can often still place a one-piece IOL in the capsular bag, provided you don’t over-inflate it. However, if the tear is large or central, plan for a three-piece IOL in the sulcus with optic capture through the anterior capsulorhexis. This may be the safer option particularly since the vitreous cavity will be filled with expansile gas at the end of the case. Once the anterior segment is stable and the IOL is secure, you can proceed with your vitrectomy and membrane peeling for the macular hole. The beauty of the combined approach is that the vitrectomy actually helps clear any lens material or OVD that slipped into the posterior cavity.
