Abstract

BackgroundA simple technique to facilitate removal of subincisional cortex in cataract surgery is presented.MethodsA disposable 27-gauge blunt needle attached to a 5.0-ml syringe containing balanced salt solution (BSS) is introduced through the side port incision into the anterior chamber. The tip of the needle is directed toward the capsule fornix beneath the incision site, and BSS is flushed to disperse the remaining cortex. Thereafter, the coaxial irrigation/aspiration device is used to remove the loosened cortex.ResultsThis technique was used in 60 eyes of 60 patients with difficulty of removing cortical remnant in the subincisional space. Subincisional cortical material was successfully removed in 93.3% (56/60 eyes). There were no intraoperative and postoperative complications related to this procedure.ConclusionsThe hydro-dispersion technique is a simple and safe approach to remove the subincisional cortical material that is difficult to manage with the standard coaxial irrigation/aspiration device.

Highlights

Removal of cortical material beneath the incision site remains challenging even in modern cataract surgery
Bimanual irrigation and aspiration techniques have been developed for safer removal of subincisional cortex [1,2,3,4,5]
When removal of subincisional cortex was difficult with a coaxial irrigation/aspiration handpiece during routine phacoemulsification and intraocular lens (IOL) implantation, this technique was applied

Summary

Introduction

Removal of cortical material beneath the incision site remains challenging even in modern cataract surgery. Bimanual irrigation and aspiration techniques have been developed for safer removal of subincisional cortex [1,2,3,4,5]. This method, entails creation of additional side port wound and special irrigation/aspiration cannulas are required. In 2002, Dewey reported a technique to use J-cannula to hydrodissect the cortex from the posterior capsule in routine cataract surgery [7]. He introduced the cannula through the main incision and irrigated the cortex from. A simple technique to facilitate removal of subincisional cortex in cataract surgery is presented
