After a posterior continuous curvilinear capsulorhexis (PCCC) causing a posterior capsule tear, how should the capsular defect be closed?

Management of Posterior Capsule Tear After PCCC

The posterior capsule defect after a PCCC-related tear is typically not "closed" surgically; instead, the tear should be converted into a controlled posterior continuous curvilinear capsulorhexis (PCCC) when possible, allowing for in-the-bag IOL placement, or managed with alternative IOL fixation strategies when conversion is not feasible.

Intraoperative Management Strategy

The key principle is converting an uncontrolled posterior capsule tear into a controlled PCCC whenever the anterior capsulorrhexis remains intact 1.

When Conversion to PCCC is Possible

• Primary approach: If the anterior continuous curvilinear capsulorrhexis (CCC) is intact, convert the posterior tear into a controlled PCCC
• Success rate: This conversion is achievable in approximately 61% of posterior capsule tears 1
• IOL placement: Once converted, in-the-bag IOL fixation can be achieved in most cases (98% in one large series) 1
• Vitrectomy consideration: Anterior vitrectomy is performed in approximately 49% of cases with posterior capsule tears to prevent vitreous traction 1

Alternative Fixation When Conversion Fails

When PCCC conversion is not possible, use these sequential options 1:

1. Neuhann anterior capsule rhexis fixation (20.5% of cases): Haptics in sulcus with optic captured through anterior capsulorrhexis
2. Standard sulcus placement (12.1% of cases): IOL placed entirely in ciliary sulcus
3. Anterior chamber IOL (6.0% of cases): Reserved for cases where bag/sulcus fixation is impossible

Critical Technical Points

The Hole Is Not "Sutured Closed"

• Unlike anterior capsulorrhexis tears which can be sutured 2, posterior capsule defects are managed by controlled enlargement or alternative IOL positioning
• The goal is controlled opening, not closure, to prevent uncontrolled radial extension

Risk of Secondary Closure

Important caveat: Even with intentional PCCC, the opening can spontaneously close postoperatively through lens epithelial cell proliferation 3, 4:

• Partial closure: Occurs in 8% of cases 3
• Complete closure: Occurs in 12% of cases, with 4% requiring Nd:YAG laser capsulotomy 3
• Mechanism: Lens epithelial cells can proliferate on the anterior hyaloid membrane, closing the defect in approximately one-third of cases 4
• High-risk populations: Young adults, diabetics, and uveitic eyes are at greatest risk for closure 3, 5

Postoperative Outcomes

When managed appropriately with PCCC conversion and in-the-bag fixation 1:

• No increased risk of clinically evident cystoid macular edema
• No increased risk of retinal detachment
• No increased risk of endophthalmitis
• Excellent visual outcomes comparable to uncomplicated cases

Key Pitfall to Avoid

Do not attempt to physically close the posterior capsule defect—this is neither technically feasible nor desirable. The intact anterior capsulorrhexis provides the structural support needed for IOL stability, while the posterior opening (whether intentional PCCC or converted tear) allows for visual axis clarity and reduces posterior capsule opacification risk.
