Cataracts surgery is the highest volume surgical procedure in the world. If untreated the eye begins to become cloudy, effecting the quality of life. Currently most affordable procedures are done manually and require great accuracy and precision, especially when working within a 4-10mm space. Accidentally piercing the back of the lens capsule can lead to possible infection, fluid leaking through the front of the eye or retinal detachment. The risk is very high and therefore surgeons must not pierce the capsule.

axsis delivers precision

Axsis has virtual boundaries which reduce the risk of lens capsule piercing as well as motion scaling and tremor reduction increases surgeon precision. The system features haptic feedback, allowing surgeons to feel differences between delicate tissues. 

Real-time OCT imaging allows a 3D and section view to supplement the normal microscope view meaning surgeons are no longer required to bend over a microscope during the procedure. A virtual boundary based on the OCT imaging ensures the robotic flexure cannot pierce the back of the lens capsule.
