A robotic laser system significantly reduces operating room time for cataract surgery patients and surgeons compared to traditional femtosecond laser setups. This robotic approach streamlines the workflow, leading to substantial time savings per case.

Area of Science:

  • Ophthalmology
  • Surgical Technology
  • Robotics in Medicine

Background:

  • Cataract surgery often involves multiple steps and room transitions.
  • Femtosecond laser technology has advanced cataract surgery, but workflow efficiencies are continually being optimized.
  • Minimizing operating room (OR) time is crucial for patient throughput and resource management.

Purpose of the Study:

  • To compare the time efficiencies of a traditional femtosecond laser platform versus a single-room robotic laser system in cataract surgery.
  • To evaluate operative time parameters for both surgeons and patients.

Main Methods:

  • A prospective, non-masked study compared 23 patients undergoing cataract surgery with a traditional femtosecond laser (LenSx) in two rooms versus 23 patients using a robotic laser (ALLY) in a single room.

  • Key time metrics including laser setup, docking, suction, total laser time, and total case times were recorded by third-party observers.
  • Time from laser completion to phacoemulsification initiation was a critical parameter evaluated.

    • Main Results:

    • The robotic laser system (ALLY) demonstrated statistically significant reductions in mean suction time (1:16 vs. 2:26), laser completion to phacoemulsification initiation (0:57 vs. 4:39), and total surgeon case time (14:27 vs. 19:40).
    • Total patient OR time was also significantly reduced with the robotic system (25:25 vs. 33:22).
    • No significant difference was found in total phacoemulsification procedure time between the two platforms.

    Conclusions:

    • The implementation of a robotic laser system in cataract surgery offers considerable time savings for both surgeons and patients.
    • This single-room, robotic approach enhances workflow efficiency compared to traditional multi-room femtosecond laser setups.
    • The study highlights the potential of robotic technology to optimize surgical processes and reduce OR time in ophthalmic procedures.
