Chandelier retroillumination–assisted torsional oscillation for cataract surgery in patients with severe corneal opacity
Accepted 3 July 2007.
We describe a technique that uses 25-gauge transconjunctival chandelier endoillumination in combination with a torsional oscillation system for cataract surgery in cases with severe bullous keratopathy. Because of the hands-free and self-retaining nature of the chandelier fiber, continuous curvilinear capsulorhexis and subsequent bimanual intraocular manipulation can be performed easily. Torsional oscillation efficiently emulsifies lens particles along with the fluidics, preventing posterior capsule rupture and endothelial cell damage. After the chandelier fiber is removed at the end of surgery, the 25-gauge incision self-seals. This technique is safe and provides excellent visualization during cataract surgery in patients with severe corneal opacities.
