Long-term Results of Two Surgical Methods for Scleral IOL Implantation and Fixation in Eyes Without Capsular Support: Yamane- Versus 4-flanged Technique
Sponsor: Medical University of Vienna
Summary
This study is a comparison of the surgical techniques and postoperative outcome between the two intrascleral IOL fixation techniques: Yamane technique versus the 4-flanged technique. The main objectives are postoperative lens tilt, duration of surgery, intra- and postoperative complication rates and scleral integrity around the flanges.

Interventions
Pars plana vitrectomy
25gauge pars plana vitrectomy: to remove the vitreous if present
IOL explantation
Removing if present a subluxated IOL from the anterior chamber or the vitreous cavity
Scleral IOL fixation Yamane Technique
Scleral IOL fixation using the Yamane technique. A 3 piece IOL (Kowa Avansee Preset) gets fixated in the sclera using only its haptics, which are externalised 2.5mm behind the blue line. The haptic ends are flanged using a thermo cautery to prevent slipping back in.
Scleral IOL fixation "4-flanged" Technique
Scleral IOL fixation using the 4 flanged technique. A 4 loop haptic IOL (Physical Micropure 123) gets fixated in the sclera using one 6.0 polypropylene suture per 2 haptic loops, which are put trough the loops in a W shape. The suture ends are externalised 2.5mm behind the blue line and its ends are flanged using a thermo cautery to prevent slipping back in.
