The SWISS IOL Technique (Small-Width Incision Scleral Suture): A Mini-Invasive Technique

Abstract

Purpose. To evaluate the outcomes and safety of a minimally invasive technique for sutured IOL scleral fixation in case of compromised capsular and iris support. Materials and Methods. In this retrospective study, we explain our mini-invasive technique and assess the outcomes in terms of visual acuity, pre- or postoperative complications, and IOL position (Sensar AR40e, AMO) in a case series of three patients. Results. The expected best corrected visual acuity could be achieved after one month. Surgeries were uneventful with a stable eye. No postoperative complications occurred except for one patient who had a conjunctival disinsertion. Neither postoperative hypotony nor raised IOP was found. Additionally, no patient experienced corneal edema at one week control, IOL dislocation, vitreous hemorrhage, or new pupil’s irregularity. Conclusions. In conclusion, each scleral technique has its own advantages and its inherent postoperative complications. To date, there is no evidence of superiority of any single technique. By improving our scleral sutured lens techniques, we could improve peroperative ocular stability, potentially decrease postoperative complication rate, and offer a rapid recovery with a stable visual acuity within a month.

“…Massa and colleagues from the Geneva University Hospitals presented the SWISS IOL, a new minimally invasive technique for the scleral fixation of intraocular lenses (IOLs) in eyes without capsular support [ 6 ]. The postoperative spherical equivalent refraction ranged between −0.75 and −2.25, and no perioperative or postoperative complications were recorded while all IOLs were well centered postoperatively without any dislocation or tilt.…”
