title: Continuous Curvilinear Capsulorhexis Performed With the VERUS Ophthalmic Caliper.
abstract: OBJECTIVE
  To compare size, circularity, and centration outcomes of continuous curvilinear capsulorhexis (CCC) performed with or without assistance from the VERUS ophthalmic caliper (Mile High Ophthalmics, Denver, CO).
  
  
  METHODS
  This was a multicenter retrospective consecutive case controlled series review.
  
  
  RESULTS
  Data from 40 consecutive cases using the VERUS device for CCC were compared to 40 consecutive cases with standard manual CCC. VERUS-assisted CCC size, circularity, and centration were closer to target compared to that of manual only procedures (P < .05). The average time from initiation to completion of the capsulotomy was shorter with manual (40 ± 11 seconds) compared to VERUS-assisted (71 ± 13 seconds) cases (P < .0001).
  
  
  CONCLUSIONS
  The VERUS ophthalmic caliper is effective at improving size, circularity, and centration of the CCC in a time-efficient manner when compared to manual procedures performed without VERUS guidance. [J Refract Surg. 2016;32(10):654-658.].
