Spectacle Independence for Pseudophakic Patients - Experience with a Trifocal Supplementary Add-on Intraocular Lens.

ABSTRACT: 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.

Project description:PurposeTo assess refractive and visual outcomes post-cataract surgery with bilateral implantation of a bi-aspheric diffractive trifocal intraocular lens (IOL).MethodsA total of 24 patients who underwent bilateral implantation with the Asqelio Trifocal IOL TFLIO130C were evaluated at the 6 months postoperative mark. Key outcome measures included refractive error, photopic monocular and binocular uncorrected and corrected distance visual acuity (UDVA, CDVA), uncorrected and corrected intermediate visual acuity (UIVA, CDIVA) at 60 cm, and uncorrected and corrected near visual acuity (UNVA, CDNVA) at 40 cm. Additionally, monocular and binocular CDNVA were assessed under mesopic conditions. Monocular and binocular defocus curves, and binocular contrast sensitivity under photopic and mesopic conditions, with and without glare, were measured. Catquest-9SF and visual symptoms questionnaires were also administered.ResultsPostoperative average values of binocular logMAR photopic CDVA, photopic CDIVA, photopic CDNVA and mesopic CDNVA were -0.01±0.06, 0.03±0.09, 0.02±0.05 and 0.19±0.13, respectively. About 100% of patients showed cumulative CDVA and CDNVA ≥20/25, and CDIVA ≥20/32. The average absolute depth-of-focus was about 4.50D. The average postoperative spherical equivalent was 0.05±0.30D and 100% and 93.75% eyes were within ±1.00D and ±0.50D, respectively. Contrast sensitivity was either within or above normal levels under both photopic and mesopic conditions, both with and without glare, except for 12 cpd under mesopic conditions with glare where the mean falls just below the normal range. Questionnaires revealed that 87.5% of patients were either satisfied or very satisfied with their vision after the surgery, and higher percentages for no difficulty in performing different activities, ranging from 70.83% to 95.83%, were reported.ConclusionThis study demonstrates that the bi-aspheric diffractive trifocal IOL yields very good visual performance across distances, fostering high satisfaction levels and minimal difficulties in daily activities.
