Long-Term Efficacy, Visual Performance and Patient Reported Outcomes with a Trifocal Intraocular Lens: A Six-Year Follow-up

Abstract

(1) Background: To evaluate the efficacy at 6 years postoperative after the implantation of a trifocal intraocular lens (IOL) AT Lisa Tri 839MP. The secondary objective was to evaluate the contrast sensitivity defocus curve (CSDC), light distortion analysis (LDA), and patient reported outcomes (PROs). (2) Methods: Sixty-two subjects participated in phone call interviews to collect data regarding a visual function questionnaire (VF-14), a patient reported spectacle independence questionnaire (PRSIQ), and questions related to satisfaction and decision to be implanted with the same IOL. Thirty-seven of these subjects were consecutively invited to a study visit for measurement of their visual acuity (VA), CSDC, and LDA. (3) Results: The mean monocular distance corrected VA was −0.05, 0.08, and 0.05 logMAR at far and distances of 67 cm and 40 cm, respectively. These VAs were significantly superior to those reported in previous literature (p < 0.05). The total area under the CSDC was 2.29 logCS/m−1 and the light distortion index 18.82%. The mean VF-14 score was 94.73, with 19.4% of subjects requiring spectacles occasionally for near distances, and 88.9% considering the decision of being operated again; (4) Conclusions: Long-term AT LISA Tri 839MP IOL efficacy results were equal or better than those reported 12 months postoperatively in previous studies. The spectacle independence and satisfaction rates were comparable to those reported in short-term studies.

Visual Performance, Satisfaction, and Spectacle Independence after Implantation of a New Hydrophobic Trifocal Intraocular Lens

“…In the present study, only 1 subject reported seldom needing spectacles for intermediate distances, while for near vision, 88% (22) achieved spectacle independence, and the remaining 12% (3) reported a need for spectacles rarely (1 patient), sometimes (1 patient), and all of the time (1 patient). In the present study, 100% of subjects reported being satisfied or very satisfied with their vision at all distances (PRSIQ, question 2 D), the same as reported by Vargas et al [ 21 ] (100%), and higher than reported by Fernandez et al [ 19 ] and Liu et al [ 22 ] (more than 90%), and Mendicute et al [ 23 ] (more than 80%).…”

“…Patient-reported spectacle independence was assessed using a non-validated Spanish translation of the English validated PRSIQ [ 12 ]. In a study assessing patient-reported spectacle independence 6 years after implantation of a trifocal IOL, Fernandez et al [ 19 ] used the same questionnaire and reported the total spectacle independence for far and intermediate distance vision, but 19.4% of subjects reported a need for spectacle use for near vision, 6.5% reported this aid was sometimes needed, and 12.9% rarely needed it. Song et al [ 20 ] reported good visual outcomes by combining a trifocal and an EDOF IOL using the Visual Function Questionnaire (VFQ-25).…”

Encouraging Visual Outcome of a New Accommodative Intraocular Lens: A Retrospective Long-Term Study with a Mean Follow-Up of 5.3 Years

“…In this cohort 84% of patients received Nd: YAG capsulotomy due to PCO. A mean time to capsulotomy of 44 months has been reported in the literature [28]. Additionally, rates of capsulotomy in other studies (e.g.…”

“…Fernández et al [28] reported disturbing optical phenomena in 32% of the cases, McNeely et al [26] in more than 40% and Brito et al [27] even in 50% of the cases. Although the literature reports the occurrence of optical phenomena with monofocal lenses [30], they do not occur that often.…”

“…The literature also reports a particularly good distance visual acuity of the trifocal lenses, whereas the near visual acuity usually shows the worst results within the three optic planes. Thus, near visual acuity of greater than 0.1 logMAR [24] [25] [26] [27] is frequently reported, in some cases even greater than 0.2 logMAR [28] [29]. Hence, trifocal lenses only partially fulfill their actual purpose (i.e.…”
