This study presents a practical, self-assembled continuous curvilinear capsulorhexis (CCC) training system. The system, including a CCC marker, aids in improving surgical skill and reducing the learning curve for residents.

Area of Science:

  • Ophthalmology
  • Surgical Education
  • Medical Devices

Background:

  • Continuous curvilinear capsulorhexis (CCC) is a critical step in cataract surgery.
  • Mastering CCC requires extensive practice and can have a steep learning curve for residents.
  • A practical, accessible self-training system is needed to enhance resident proficiency.

Purpose of the Study:

  • To describe a practical, self-assembled continuous curvilinear capsulorhexis (CCC) self-training system.
  • To facilitate resident self-training and shorten the CCC learning curve.
  • To evaluate the effectiveness of the training system using objective parameters.

Main Methods:

  • A prospective experimental study involving 600 capsulorhexis cases.
  • Development and utilization of a self-assembled device for CCC practice and testing.

  • Categorization of residents into three groups based on prior CCC experience (<50, 400-500, >1000 cases).
  • Subgroup analysis based on anterior chamber cover and CCC marker presence/magnification.
  • Statistical evaluation of acircularity index (AI), axis ratio (AR), and capsulorhexis time.

    • Main Results:

    • Significant differences in CCC parameters (AI, AR, time) were observed among resident experience groups across various simulated conditions.
    • Increasing manipulation experience correlated with decreased capsulorhexis time, AI, and AR.
    • The CCC marker significantly improved AI and AR, bringing them closer to ideal values (1.0) in specific subgroups.
    • The training system demonstrated effectiveness in differentiating skill levels and improving performance metrics.

    Conclusions:

    • The self-assembled CCC self-training system is a practical and effective tool for surgical education.
    • The inclusion of a CCC marker is beneficial for size specification and centration during resident training.
    • This system offers a viable method to accelerate skill acquisition and improve outcomes in CCC performance.
