What happens if YAG capsulotomy is incomplete?

1 min read

An incomplete YAG capsulotomy occurs when residual posterior capsule opacity remains in the central visual axis after the initial laser treatment, resulting in persistent visual symptoms despite having undergone the procedure. ³ This occurs in a minority of cases, estimated at 5% to 10%, and typically reflects particularly dense or thick posterior capsule opacification, fibrotic changes that resist laser disruption, or conservative initial energy application to minimise complication risk.

When capsulotomy is incomplete, patients report that vision has improved somewhat but remains suboptimal, less blurred than before treatment, but not as clear as expected. ² Slit lamp examination reveals that the capsulotomy opening is either too small, irregular, or that significant opacification persists at the periphery of the opening, encroaching into the visual axis.

The management of incomplete capsulotomy is straightforward: a second YAG laser session is performed to enlarge the capsulotomy opening or clear residual opacification. ¹ This repeat treatment is typically scheduled within two to four weeks of the initial procedure once any post-operative inflammation has settled. The second session follows the same procedural steps as the first: pupil dilation, topical anaesthesia, contact lens application, and targeted laser delivery to residual capsular tissue.

Patients should confirm in advance whether repeat treatment is included within the initial fee. ² Rarely, in cases where posterior capsule opacification is extremely dense or fibrotic, surgical capsulectomy, removal of the capsule via vitrectomy, may be required, though this is exceptional.
