Diode laser energy delivered via a 100-micron fiberoptic probe precisely cuts ocular tissues like the lid and cornea. This precise laser surgery results in minimal thermal damage, with coagulation zones up to 50 microns.

Area of Science:

  • Ophthalmology
  • Biomedical Engineering
  • Laser Surgery

Background:

  • Precise surgical cutting of delicate ocular structures is critical in ophthalmic procedures.
  • Minimizing thermal damage to surrounding healthy tissue is a key challenge in laser-based surgery.

Purpose of the Study:

  • To evaluate the efficacy and precision of diode laser energy delivered through a fiberoptic probe for cutting ocular tissues.
  • To characterize the thermal effects and coagulation zone produced by the laser on ocular structures.

Main Methods:

  • Diode laser energy was applied using a 100-micron diameter fiberoptic probe tip.
  • Continuous mode laser energy at 2.5 watts was used for incising the eyelid, cornea, and perforating the glove.
  • The resulting incised borders were examined to measure the extent of coagulation into healthy tissue.

Main Results:

  • The diode laser effectively cut ocular structures including the eyelid and cornea.
  • The laser probe facilitated perforation of the glove, demonstrating cutting capability.
  • Coagulation into healthy tissue at the incised border ranged from 10 to 50 microns.

Conclusions:

  • Diode laser energy delivered via a fine-tipped fiberoptic probe offers a precise method for ocular tissue dissection.
  • The observed coagulation zone suggests controlled thermal effects, important for minimizing collateral damage in ophthalmic surgery.
