Observation of Visual Quality after Femtosecond Laser-Assisted Cataract Surgery Combined with Trifocal Intraocular Lens Implantation

Abstract

Objective. This study is the first observation of Alcon’s PanOptix trifocal intraocular lens (IOL) implanted in 55 cataract patients with femtosecond laser-assisted cataract surgery. Methods. Fifty-five patients (63 eyes) with cataract were treated with femtosecond laser-assisted cataract surgery combined with trifocal IOL implantation. Visual acuity, defocus curve, higher order aberration (HOA), refractive stability, eyeglass removal rate, and satisfaction were evaluated and analyzed. Results. We found that the visual acuity of patients with near, intermediate, and distance vision was better than 0.1 LogMAR at 1, 3, and 6 months after the completion of surgery. The uncorrected near visual acuity (UCNVA), uncorrected intermediate visual acuity (UCIVA), and uncorrected distance visual acuity (UCDVA) of patients at 1, 3, and 6 months after surgery were compared with those before operation, showing statistical significance. Six months after the operation, all patients’ surgical eyes had a smooth transition in the defocus range from +0D to -2.5D, and the visual acuity of the surgical eyes reached a level better than 0.1 LogMAR. The statistical results of 6-month follow-up showed that the eyeglass removal rate at near, intermediate, and far distances was 100%. At 6 months postoperatively, only 1 case had nocturnal glare, which affected life; 3 cases developed glare and halo but did not affect life. The patient satisfaction rate was 98.18%. Conclusions. Femtosecond laser-assisted cataract surgery with trifocal IOL implantation can remove the lens from the patient with satisfactory visual quality and significantly improve the postoperative satisfaction of the patient.

Comparison of short-term clinical outcomes of a diffractive trifocal intraocular lens with phacoemulsification and femtosecond laser assisted cataract surgery

“…Similar UIVA outcomes have been reported by other authors for the same trifocal IOL [ 18 , 36 , 37 ]. Compared to the results of Ma et al’s [ 38 ] study of trifocal IOL implantation via FLACS, they applied more satisfactory and stable UNVA, UIVA and UDVA results. The source of the difference may be related to the follow-up time.…”

“…The source of the difference may be related to the follow-up time. As in this study we only observed post-operative visual acuity at 1 month postoperatively, while their team observed visual acuity at 1, 3 and 6 months postoperatively [ 38 ]. Several other factors may contribute to this difference, such as differences in patient samples (e.g.…”

“…The defocus curve is an important indicator for evaluating the performance of multifocal IOLs, mainly reflecting the patient’s continuous visual range [ 38 ]. The 1-month postoperative defocus curve of this study showed two peaks at 0D and − 2.5D in FLACS group while showed three peaks at 0D, -1.5D and − 2.5D in PHACO group, but the transition of these curves was smooth in the middle.…”
