Summary

Sutureless clear corneal incision (CCI) is the most commonly used technique for creating an entrance wound in cataract surgery. Corneal incision hydration enhances wound tightness and reduces postoperative fluid suction from the ocular surface into the anterior chamber; thereby, loweres the risk of postoperative endophthalmitis. Various hydration methods have been employed to close corneal incisions. Standard CCI hydration may be ineffective in sutureless incisions with central wound gaping.

Authors described a new technique of hydration: a posterior flap hydration technique. This study evaluates its effect on corneal wound tightness immediately after hydration, and assess wound architecture on the first postoperative day using anterior segment optical coherence tomography (AS-OCT).

Interventions

PROCEDURE

Patient with visible central wound gap of the CCI

Patient with visible central wound gap of the CCI were treated with posterial flap hydration. Standard hydrodissection and hydrodelineation cannulas are used for hydration. Cannulas with flat ends, including the cortical cleaving hydrodissector 27 G × 7/8 (BVI Visitec) and a hydrodissector 27 G × 7/8 (Sterimedix Ltd.), are employed. The morphology of the central wound before and after hydration is evaluated using video recordings. On the first postoperative day (20-24 hours after surgery), anterior segment optical coherence tomography (AS-OCT) analysis of corneal incisions is performed with a Tomey Casia 2 device using the Post-op Cataract AS Global Scan application.
