Abstract
Background: There is an increasing need for improved microsurgical techniques in the eye. Delivery of small quantities of chemicals or cells into specific retinal locations, for example, cannot be achieved with hand‐held instruments. The present paper describes the design principles used in the development of a robotic ocular ultramicrosurgical system and the results from preliminary animal trials. Methods: We have developed a robotic ocular ultramicrosurgical system and a range of instruments for specific intraocular applications. Results: We have successfully used the system for intravascular (< 70 >) drug delivery, implantation of microdrainage devices and the intraretinal manipulation of microelectrodes with minimal damage. Conclusion: A clinically usable system using the same principles appears feasible.
