Purpose:

To evaluate RayOne pre-loaded injector system with new ‘Lock and Roll’ technology for implantation of hydrophilic lens with 6mm diameter through 2.2mm incision

Methods:

While traditional injector folds the lens in to halves, the new ‘Lock and Roll’ technology allows the lens to be folded in to a cylinder shape. This significantly reduces the force required to push the lens and allows the lens to negotiate through the injector tip with external diameter of only 1.65mm. Thus, RayOne system makes it possible to implant a hydrophilic lens with 360 degree enhanced edge and anti-vaulting haptics through 2.2mm incision. 20 consecutive implantations done by single surgeon were evaluated for ease of RayOne system preparation, implantation, unfolding process and any visible damage to the lens or injector nozzle under operating microscope.

Results:

RayOne pre-loaded system required few easy steps to prepare in theatre lighting conditions. It was easy to negotiate nozzle tip through 2.2mm incision single handed using either wound assisted or un-assisted technique. There was no difficulty experienced in starting implantation with 45-degree clockwise rotation of nozzle tip followed by counter rotation once the optic started unfolding. None of the cases showed any undue lens rotation when unfolding or visible damage to lens or nozzle under operating microscope. In every case, the lens unfolded in correct configuration and followed predicted path during implantation.

Conclusions:

RayOne pre-loaded injector system using ‘Lock and Roll’ technology was found to offer safe, predictable and reproducible implantation of hydrophilic lens with 6mm optic and 360-degree enhanced edge through 2.2mm incision.
