Bimanual teleoperated robotic penetrating keratoplasty (PK) is feasible in porcine and human eyes. This robotic approach allows for precise suturing in corneal transplantation, paving the way for future advancements.

Area of Science:

  • Ophthalmology
  • Robotic Surgery
  • Surgical Innovation

Background:

  • Robotic ocular microsurgery, including corneal suturing, has demonstrated feasibility in porcine models.
  • Previous studies established the potential for robotic assistance in delicate eye procedures.

Purpose of the Study:

  • To evaluate the feasibility of bimanual teleoperated robotic penetrating keratoplasty (PK).
  • To assess the procedure's applicability in both porcine and human eyes.

Main Methods:

  • Utilized the da Vinci surgical robot with specialized instruments for corneal procedures.
  • Performed mechanical trephination, cardinal sutures, and continuous nylon sutures remotely.
  • Documented surgical steps using high-resolution photography and videography.

Main Results:

  • Successfully executed robotic penetrating keratoplasty on both porcine and human eyes under natural anatomical conditions.
  • Demonstrated precise continuous suture placement facilitated by wristed-end effector instruments.
  • Confirmed that orbital rims and nasal structures did not impede surgical maneuverability.

Conclusions:

  • Teleoperated robotic penetrating keratoplasty is technically achievable in human subjects.
  • Future research will focus on integrating femtosecond laser technology and further automation into robotic PK.
