The spot size of Selective Laser Trabeculoplasty (SLT) is typically 500 microns, which is equivalent to 0.5 millimeters.
This spot size is crucial for the precise delivery of laser energy to the trabecular meshwork, the tissue responsible for draining fluid from the eye.
Here's why the spot size matters:
- Targeting the right tissue: The 500-micron spot size allows the laser to target the trabecular meshwork effectively, minimizing damage to surrounding tissues.
- Minimizing collateral damage: The small spot size minimizes the risk of collateral damage to other structures in the eye, like the cornea or lens.
- Optimizing energy delivery: The laser energy is concentrated within the small spot size, ensuring efficient and effective treatment.
The spot size of SLT is a key factor in its effectiveness and safety. It allows for precise targeting of the trabecular meshwork, minimizing damage to surrounding tissues and maximizing treatment efficacy.
