A new robotic ocular ultramicrosurgical system enables precise delivery of drugs and cells within the eye. This advanced robotic system shows promise for future clinical applications in ophthalmology.

Area of Science:

  • Ophthalmology
  • Robotics
  • Microsurgery

Background:

  • Current handheld instruments lack precision for targeted ocular delivery.
  • Need for advanced techniques in ocular microsurgery for precise interventions.
  • Limitations in delivering small quantities to specific retinal locations.

Purpose of the Study:

  • To describe the design principles of a robotic ocular ultramicrosurgical system.
  • To evaluate the system's feasibility through preliminary animal trials.
  • To develop instruments for specific intraocular applications.

Main Methods:

  • Development of a robotic ocular ultramicrosurgical system.
  • Creation of specialized instruments for intraocular procedures.
  • Testing the system in preliminary animal trials.
