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. In none of the cases, complications including knot slippage, suture exposure or hypotony were observed. All patients were followed up for 6 months. The uncorrected distance visual acuity was significantly improved and the IOLs positions remained stable. The described technique might be a simple, effective and safe alternative to flanged scleral fixation approaches.

Herein, we provide evidence that human regulation of aqueous outflow is by a pump-conduit system similar to that of the lymphatics. Direct observation documents pulsatile aqueous flow into Schlemm's canal and from the canal into collector channels, intrascleral channels, aqueous veins, and episcleral veins. Pulsatile flow in vessels requires a driving force, a chamber with mobile walls and valves.

Introduction: The aim of this study was to evaluate the outcome of the modified Carlevale intraocular lens (IOL) fixation technique, using two different vitrectomy ports (23- vs. 27-gauge) as anchor fixation.
Methods: Retrospective, consecutive study of 282 eyes (282 patients) who underwent a secondary IOL implantation using the Carlevale IOL (Soleko IOL Division, Italy) with two anchor haptics for intrascleral implantation with either 23- or 27-gauge (G) port.

A technique using the single-string, closed-loop fixation method to reposit dislocated triple-looped haptic intraocular lens (IOL)-capsular bag complex is described. The long needle or curved needle with a 10-0/8-0 polypropylene suture and a 27/30-gauge needle were used as the guide needle to pass through the fenestrated haptics twice. The scleral interlaminar course was used as the fixed point.

Purpose: To describe a flapless technique for two-point fixation of intraocular lens (IOL) with four fenestrated haptics.
Methods: A transconjunctival puncture of 1-mL syringe needle was used to guide the suture needle out of the eye. The suture was taken out of the eye through the corneal incision, passed through the pair of fenestrated haptics of the IOL and then securely tied with overhand knots.
