Capsulorrexis circular continua manual sin viscoelástico: técnica, características y ventajas

Abstract

Introduction: The main goals of using viscoelastic substances during some phases of modern cataract surgery with phacoemulsification are to achieve greater stability in the anterior chamber and to protect corneal endothelial cells. Capsulorhexis is a major step for adequate cataract extraction and subsequent correct intraocular lens centering. Strategies differ in the tools used for the creation of capsulorhexis, which can be either a cystotome, utrata forceps or femtosecond laser; however, since they generally have previous use of viscoelastic substances in common, our goal is to propose a technique involving the use of a cystotome under continuous irrigation requiring no previous use of viscoelastics.
Materials and methods: Our technique features a variation in the traditional capsulorhexis technique with previous viscoelastic use. We propose starting with the use of a 27-gauge cystotome with continuous irrigation through a single side-port incision created with a straight 23-gauge knife requiring no viscoelastic.
Conclusions: The continuous circular capsulorhexis technique using a cystotome under continuous irrigation seems to be safe, simple, reproducible and requires no viscoelastic, therefore, it may be applied on a large scale and with a short learning curve.
