Area of Science:

  • Ophthalmic Surgery
  • Surgical Technology
  • Ergonomics in Medicine

Background:

  • Conventional surgical armrests present challenges in height and position adjustment during procedures.
  • Surgeon fatigue and arm tremors can negatively impact surgical precision and patient outcomes.

Purpose of the Study:

  • To evaluate the efficacy of a freely movable armrest (FMA) in mitigating surgeon fatigue and arm tremors.
  • To determine if FMA improves surgical accuracy in ophthalmic procedures.

Main Methods:

  • A basic study involved porcine eye suturing with and without FMA, quantifying tremor and fatigue.
  • A clinical study assessed surgeon fatigue during corneal transplantation, cataract, and glaucoma surgeries with and without FMA.

Main Results:

  • FMA significantly reduced resting hand tremor (p < 0.0001) and subjective fatigue scores (p = 0.0465) in the basic study.
  • No significant difference in suturing accuracy was observed.
  • Clinical studies indicated a trend towards reduced fatigue during corneal transplantation and glaucoma surgeries with FMA.

Conclusions:

  • Freely movable armrests (FMA) offer a valuable solution for stabilizing the surgeon's arm.
  • FMA demonstrates potential in enhancing ophthalmic surgery quality by decreasing hand tremor and surgeon fatigue.
