AB - Purpose: To evaluate the refractive and functional outcomes of the trifocal 1stQ AddOn®
(Medicontur) supplementary intraocular lenses (IOLs) designed for implantation into the
ciliary sulcus.
Patients and Methods: The study included 18 eyes of 11 pseudophakic patients with
uncomplicated previous implantation of monofocal capsular bag IOLs. These patients had a
desire for spectacle independence. Distance, intermediate and near visual acuities were
measured, and defocus curves were plotted over a period of 6 months following implantation
of the add-on IOLs. Intraocular pressure (IOP), endothelial cell density measurements and
biomicroscopic evaluation were also performed.
Results: In this study, 83.3% of eyes had spherical refractions within ±0.5 D from
emetropia and 100% of eyes had spherical equivalent refractions that were within ±1.0
D of the target refraction. Visual acuities and defocus curves clearly confirmed trifocal
optical performance (UDVA=0.03 ±0.05; UIVA=0.21 ±0.04; UNVA=0.12 ±0.04 logMAR;
expressed as mean ±SD). Depth of focus showed identical results (DOF=0.486 D)
compared to a trifocal capsular bag IOL, while the defocus curve was found to be
superior in the intermediate and near ranges when compared to a trifocal capsular bag
IOL. All patients achieved spectacle independence at all distances. All add-on IOLs were
well positioned in the ciliary sulcus. No negative changes were noted in connection with
endothelial cell counts, IOPs, the angle structure during surgery and during the follow-up
period.
Conclusion: The supplementary trifocal add-on IOL seems to be a safe, efficient and stable
solution for achieving spectacle independence in pseudophakic patients with monofocal primary
IOLs.
