[Cataract surgery. Anterior capsulorrhexis technique].

The cataract surgery is in a continuous dynamic because of the technological progress. The last years the surgical technique for cataract has changed and the most important progresses are the use of small incisions that don't require sutures, the realise of the anterior capsulotomy with smooth margins (continuous circular capsulorrhexis) and the extracapsular extraction of the cataract by phacoemulsification. The authors described the most usual techniques of the anterior capsulotomy with the advantages offered by capsulorrhexis, an important surgical step from the manual extracapsular extraction of the cataract to phacoemulsification.
