Hoya iSert® 254 Preloaded IOL

Fully preloaded 100% hydrophobic aspheric 1 piece IOL
Simple, fast, predictable

HOYA iSert® delivers a faster average IOL delivery time than manually loaded IOL delivery systems.

Improves efficiency and productivity

Preloaded features streamline operating procedures and optimise clinical efficiencies.

Sharp optic edge

Proven ABC Design of optic provides patients with a sharp visual image. The square edge helps to minimise posterior capsule opacification (PCO).

Simple and superior injector

Simple and superior ease of use of the injector, through a small 2.2mm incision.

Proven hydrophobic IOL material

Over 10 million IOLs sold worldwide over 15 years.
