VTICL size was calculated using the standard STAAR Visian ICL calculation software for phakic eyes. Postoperative study visits (1 day, 1 week, 3 months and 6 months after VTICL implantation) included UDVA, corrected distance visual acuity (CDVA), VTICL axis alignment, vault (space between mIOL and VTICL), IOP and documentation of adverse events.Results: At 6 months, mean UDVA (logMAR) increased from 0.26 preoperatively to −0.01 (P<0.001) while mean CDVA remained unchanged. Mean VTICL misalignment from the preoperative target axis was 5.3° and mean vault was 1385 μm. In the initial phase of the study, 2 VTICL had to be exchanged due to oversizing.Conclusion: Piggy-back low power VTICL can efficaciously correct residual refractive error after mIOL implantation and significantly increase UDVA. Advantages of this novel surgical approach include: VTICL availability in small diopter steps, no significant surgical-induced astigmatism, atraumatic and reversible procedure.Keywords: multifocal intraocular lens, ICL, Visian Implantable Collamer Lens®; piggy-back, add-on, residual refractive error  Duncker GIWSasse ACDuncker TDove Medical Pressarticlemultifocal intraocular lensiclimplantable collamer lenspiggy-backadd-onresidual refractive errorOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 13, Pp 1689-1702 (2019)
