A practical continuous curvilinear capsulorhexis self-training system
Purpose: To describe a practical, self-assembled continuous curvilinear capsulorhexis (CCC) self-training system to facilitate resident self-training and shorten the CCC learning curve.

| description | Purpose: To describe a practical, self-assembled continuous curvilinear capsulorhexis (CCC) self-training system to facilitate resident self-training and shorten the CCC learning curve. Methods: This was a prospective experimental study that included a total of 600 capsulorhexis cases. A device for CCC practice was self-assembled and used for training and testing. Based on capsulorhexis manipulation experience, three main groups of residents (A, capsulorhexis experience with <50 cases; B, capsulorhexis experience with 400–500 cases; and C, capsulorhexis experience with >1000 cases) were created. Furthermore, based on different capsulorhexis conditions, each main group was divided into four subgroups (1, CCC without an anterior chamber cover and capsulorhexis marker; 2, CCC with an anterior chamber cover without a capsulorhexis marker; 3, CCC with an anterior chamber cover and a capsulorhexis marker; and 4, CCC with an anterior chamber cover and a capsulorhexis marker under 2.5 times magnification). Three CCC-related parameters, including acircularity index (AI), axis ratio (AR), and capsulorhexis time, were statistically evaluated. Results: We compared the differences in study parameters among 50 consecutively completed capsulorhexis cases by one trainee with different capsulorhexis experience in each subgroup. The CCC-related parameter values in subgroups 1 and 4 were significantly different among the three groups (P < 0.001). The capsulorhexis time in subgroup 2 was significantly different among the three groups (P < 0.001). The capsulorhexis time and AI in subgroup 3 were significantly different among the three groups (P < 0.001). Moreover, with increasing manipulation experience (from group A–C), the capsulorhexis time, the AI, and AR tended to decrease. With the help of the CCC marker, in subgroups 3 and 4, the AI and AR were closer to 1.0. Conclusion: This self-assembled CCC self-training system is practical. The CCC marker seems helpful for size specification and centration during self-training. |
