Purpose
To evaluate the technical feasibility of robot-assisted gonioscopic micro-intervention
using a novel system for ophthalmic robot-assisted surgery
Setting/Venue
Preclinical surgical robotic system
Methods
A surgical setup for robot-assisted micro-intervention in the anterior segment was
developed for specific application in ab-interno micro-interventional glaucoma surgery (MIGS).
The surgical system was interfaced with existing implantable and non-implantable MIGS
instrumentation to achieve targeted, single micron-level precision in the trabecular meshwork
Results
Successful surgical goniotomy and trabecular stenting were performed with robotic
assistance and manually in a synthetic model of trabecular MIGS. Two
anterior segment surgeons completed 10 consecutive trials each of ab-interno goniotomy with
robotic assistance and manually using a standard goniotomy knife, and
more than 10 clock hours of goniotomy using a flexible micro-interventional goniotomy instrument. The simulated iStent inject W deployment was
successfully achieved within the trabecular meshwork band in 100% of attempts manually and
using the robotic-assisted interface for stent implantation
Conclusions
A first-in-class micro-interventional system for robotic-assisted MIGS surgery can successfully achieve implantable and non-implantable interventions in the anterior segment.This is the first demonstration of the feasibility of robot-assisted ophthalmic gonioscopic-surgery
