• laser light stimulates the body’s own healing response to lower eye pressure
  • effective as primary, adjunctive or repeat therapy
  • safe, office-based procedure
  • reimbursed by most insurance policies
OptoSLT is a laser for Selective Laser Trabeculoplasty. This is a laser procedure used to treat open angle glaucoma by reducing the pressure within the eye. The laser system is a Q-switched frequency doubled Nd:YAG laser emitting short pulses at the wavelength of 532 nm. OptoSLT emits pulses at levels from 0.2 to 2.6 mJ. Red laser diode aiming beam with continuous power adjustment allows precise targeting of the SLT laser. OptoSLT can be integrated into the e-SlitLight or adapted to various slit lamps.
