Continuous tear capsulotomy, or capsulorhexis, permits secure and precise placement of a posterior chamber intraocular lens. This technique can be used open sky during triple procedures combining penetrating keratoplasty with cataract extraction and intraocular lens insertion. Expression of the nucleus through a continuous tear capsulotomy can be difficult. Incisions in the anterior capsule facilitate nucleus expression but can extend, obviating the advantages of continuous tear capsulotomy. With phacoemulsification using low irrigation and adequate ultrasound power, the nucleus can be completely emulsified or fragmented into easily removable pieces. This permits continuous tear capsulotomy to be part of triple procedure surgery.
连续环形撕囊术，即囊膜撕开术，可确保后房型人工晶状体安全精确植入。该技术可在穿透性角膜移植联合白内障摘除及人工晶状体植入的三联手术中于开放视野下使用。通过连续环形撕囊术娩出晶状体核可能会很困难。在前囊膜上做切口有助于晶状体核娩出，但切口可能会扩大，从而抵消连续环形撕囊术的优势。使用低灌注和足够的超声能量进行超声乳化时，晶状体核可被完全乳化或破碎成易于取出的小块。这使得连续环形撕囊术能够成为三联手术的一部分。
