The following are needed to perform a trabeculectomy:

  • Magnification: An operating microscope is recommended, but a powerful binocular loupe can be used if a microscope is not available.

  • Surgical instruments: The basic ophthalmic microsurgical instrument set is needed.

  • Hemostasis: Electrocautery or diathermy is recommended. A heated metal cautery method is not recommended because of the difficulty controlling the amount of heat delivered. Excessive tissue contraction is often induced by this method.

  • Anterior chamber opening/sclerostomy: A trabeculectomy punch (eg, Kelly) is recommended for more precise and controlled excision of the corneal block (sometimes inaccurately called the trabecular block) but this step can also be performed using forceps, a blade, and Vannas scissors.
