Posterior Capsular Tear Management Flowchart

Posterior capsule rupture (PCR) is a complication every cataract surgeon eventually encounters. Outcomes depend far less on whether it happens and far more on how promptly it is recognized and how methodically it is managed. The core principle: slow down, stabilize, reassess — do not chase problems reactively.

Step 1: Recognize early

• Sudden deepening of the anterior chamber, a subtle "pupil snap" or momentary dilation, or a fragment that suddenly seems to disappear posteriorly are all classic warning signs
• A sudden loss of followability/holdability of nuclear fragments during phaco suggests loss of capsular support
• Do not chase lens fragments that drop posteriorly — attempting to retrieve them anteriorly risks vitreoretinal traction and retinal tears; if fragments are in the vitreous cavity, this needs a posterior segment approach (often a separate pars plana vitrectomy by a retina specialist), not anterior segment maneuvers

Step 2: Stabilize the chamber

• Stop phacoemulsification immediately; do not withdraw instruments from the eye abruptly, as this can further prolapse vitreous
• Inject dispersive OVD behind the remaining nuclear material and in front of the rupture to tamponade vitreous and prevent further prolapse before removing instruments
• Maintain a closed, pressurized system throughout — avoid sudden pressure fluctuations that encourage vitreous to prolapse forward

Step 3: Anterior vitrectomy

• Remove all vitreous from the anterior chamber, the wound, and the iris surface — the pupil should be round and free of vitreous strands by the end
• Preservative-free triamcinolone acetonide is a valuable adjunct: it stains vitreous strands white, making otherwise invisible vitreous visible and confirming a complete vitrectomy
• Bimanual anterior vitrectomy through separate infusion and cutter incisions (rather than a single coaxial approach) reduces vitreoretinal traction compared to older "sponge and scissors" technique, which should be avoided if at all possible
• A pars plana approach may be preferred over an anterior approach in some cases, depending on surgeon experience and the extent of posterior vitreous involvement

Step 4: Decide on IOL placement

Special case: posterior polar cataract

Posterior polar cataracts carry a pre-existing weakness or dehiscence in the posterior capsule in a meaningful proportion of cases. Avoid hydrodissection in these eyes — use gentle viscodelineation instead, since standard hydrodissection can extend a pre-existing posterior capsular defect into a full rupture.

Always remember

• Early recognition matters more than any single technical maneuver
• Do not panic — pause, stabilize, and reassess before continuing
• Inform the patient of the complication and the plan going forward
