Purpose:
To present a modified surgical technique for implantation of the sutureless scleral-fixated hydrophilic intraocular lens (FIL SSF).
Methods:
Single surgeon retrospective case series and review of surgical videos with step-by-step technique analysis. Uncorrected and best corrected visual acuity (UCVA and BCVA), refractive error (spherical equivalent), full clinical examination with intraocular pressure (IOP) measurement, endothelial cell density on corneal specular microscopy and macular optical coherence tomography (OCT) were recorded at baseline, 1, 4 and 8 weeks postoperatively.
Results:
The FIL SSF IOLs were successfully implanted using the so-called "full reverse" technique, having the lens loaded in the injector in an upside-down fashion, as opposed to IOL technical specifications. In all cases, the FIL SSF IOL was properly placed in the ciliary sulcus, well-centered and without signs of tilt. Follow up figures at 2 months are consistent with published data, confirming the potential benefits of the new implantation technique.
Conclusion:
In our preliminary experience, the "full reverse" technique of the FIL SSF IOL has proven effective in preventing incorrect IOL orientation in 100% of cases. However, larger prospective controlled studies and longer follow up are required to either support or disprove our results.
