Intrascleral anchoring knot on the double suture without peritomy for fixation of intraocular lens.

A new minimally invasive technique for universal fixation of any posterior chamber intraocular lens (IOL), iris prosthesis or capsular tension device (CTD), both for rescuing in case of dislocation and for secondary implantation, is described. It uses intrascleral anchoring knot on the reinforced double 9-0 polypropylene suture without conjunctival opening or scleral dissection. The technique was applied for scleral fixation of the S-shaped monoblock acrylic IOL dislocated into the vitreous cavity in 1 eye, and decentered IOL-CTD-capsular bag complexes in 3 eyes.

Experimental femtosecond laser-assisted nanosurgery of anterior lens capsule.

Purpose: To investigate femtosecond laser-assisted nanosurgery of the anterior lens capsule in a prospective in vitro study.

Methods: Eight anterior lens capsules obtained during conventional phaco surgery were irradiated with a nonamplified 80-MHz near-infrared 800-nm titanium:sapphire femtosecond laser. Line intratissue laser cuts were examined by femtosecond multiphoton laser scanning microscopy (MLSM) and transmission electron microscopy (TEM).

In vitro femtosecond laser-assisted nanosurgery of porcine posterior capsule.

Purpose: To investigate femtosecond laser-assisted nanosurgery of the posterior capsule in a prospective in vitro animal study.

Setting: Department of Ophthalmology and Eye Hospital, University of Saarland, Homburg, and Fraunhofer Institute for Biomedical Engineering, St. Ingbert, Germany.
