To evaluate usefulness of a new semicircular capsulotomy marker in continuous curvilinear capsulorrhexis (CCC).In 20 eyes of 20 patients who underwent cataract surgery, a newly designed semicircular marker with an internal diameter of 5.5 mm was used to place a circular mark directly on the lens capsule. The mark was then used as a guide to complete CCC of the set diameter. The resultant size of CCC in each case was confirmed by analysis of the video image.The average CCC diameter size was 5.2 ± 0.3 mm. In all cases, the edge of the intraocular lens was completely covered by the anterior capsule.The semicircular capsulotomy diameter marker was useful in making a complete CCC of a set diameter.
