    The study evaluated the effectiveness of adjunctive ab-interno goniotomy during phacoemulsification with goniosynechialysis in chronic angle-closure glaucoma.

  • 2

    A total of 102 eyes were analyzed, with 54 receiving Phaco-GSL alone and 48 receiving adjunctive goniotomy.

  • 3

    Adjunctive goniotomy showed higher 24-month qualified-failure-free survival compared to Phaco-GSL alone, with a weighted hazard ratio of 0.475.

  • 4

    Doubly robust estimates indicated that adjunctive goniotomy favored medication-free complete success and qualified success at 24 months.

  • 5

    The study concluded that adjunctive goniotomy may improve surgical control, but individualized benefit estimates require further validation.
