Continuous circular capsulorhexis (CCC) was demonstrated independently by Thomas Neuhann, Kimiya Shimizu, and Howard Gimbel in the 1980s and it finds mention in the landmark paper by Gimbel and Neuhann. The authors describe a technique of achieving the rhexis in a stable, viscoelastic-filled anterior chamber using the tunnel floor as the entry. This gets covered by the roof of the tunnel postoperatively and, therefore, does not leak. There is no oar-locking or striae even when cystitome goes beyond the edge of the tunnel. As there is no escape of the viscoelastic substance, there is no change in the pressure or shallowing of the anterior chamber. It is a useful technique for beginners. It is of great help in difficult cases like intumescent cataracts, shallow anterior chambers, hyperopes, nanophthalmos, pseudoexfoliation, small non-dilating pupils, intraoperative floppy iris syndrome (IFIS), and phacomorphic glaucoma.
