But proponents say what is new about the technology is the size of the incision - about the size of a fullstop on a page.But proponents say what is new about the technology is the size of the incision - about the size of a fullstop on a page.
This, according to Sheraz Daya, a consultant ophthalmologist at Queen Victoria Hospital, "makes it safer because the eye contents remain steady, under very precise control by the surgeon.This, according to Sheraz Daya, a consultant ophthalmologist at Queen Victoria Hospital, "makes it safer because the eye contents remain steady, under very precise control by the surgeon.

Other consultants agreed with Mr Daya's assessment, although they stressed that Stellaris was not the only device capable of reducing the incision to 1.8mm.Other consultants agreed with Mr Daya's assessment, although they stressed that Stellaris was not the only device capable of reducing the incision to 1.8mm.

"The only problem is many of the lenses on the market aren't yet small enough to fit through this kind of incision, so one side of the technology has yet to catch up with the other.""The only problem is many of the lenses on the market aren't yet small enough to fit through this kind of incision, so one side of the technology has yet to catch up with the other."
