    The bag-in-the-lens (BIL) technique optimizes intraocular lens (IOL) centration by utilizing both anterior and posterior capsulorhexis.

  • 2

    BIL IOL design features a biconvex optic and two elliptical haptics, creating an equatorial groove that captures residual lens epithelial cells.

  • 3

    This technique effectively prevents posterior capsular opacification (PCO), maintaining visual clarity and reducing the risk of complications.

  • 4

    The BIL method was introduced in 2002 by Tassignon and has been validated through experimental studies in both rabbit and human eyes.

  • 5

    Surgical success relies on precise capsulorhexis sizing and centration, with the BIL IOL providing enhanced stability postoperatively.
