Hydro-visco-implantation Technique for Wound-assisted Foldable Intraocular Lens Implantation During Microincision Cataract Surgery

We have described a hydro-visco-implantation technique (simultaneous use of sodium hyaluronate and balanced salt solution) for wound-assisted intraocular lens (IOL) implantation and passive removal of ophthalmic viscosurgical device (OVD). In the technique, the capsular bag was filled approximately up to half with OVD, and anterior chamber was formed by bimanual irrigation cannula with continuous irrigation mode from the side port. Sometimes after adequate tonus is provided, continuous mode could be off to reduce wash effect on OVD during injection of IOL. Injection of foldable IOL with the support of wound edges was completed. While the continuous irrigation mode was on, firm downward pressure was applied with the tip of aspiration canula to the posterior lip of main incision, and dynamic outflow was created, and viscoelastic material was removed from the eye.
