“…We recommended patients with HOA ≤ 0.5 μm received trifocal IOLs implantation, for high HOA might affect visual quality after surgery. 19 A primary limitation of this study is the absence of a comparison group. The PanOptix IOLs utilized in this investigation were not contrasted with other presbyopia-correcting intraocular lenses, such as AT Lisa tri 839 MP or TECNIS Synergy.…”

Purpose To examine the visual outcomes, particularly at 33 cm, and assess patient satisfaction following the implantation of a diffractive trifocal intraocular lens (IOL) and its toric variant. Patients and Methods This prospective single-arm observational study involved 45 Chinese patients (90 eyes) underwent bilateral cataract surgery and PanOptix or PanOptix toric intraocular lenses (IOLs) implantation. Postoperatively, visual acuity was evaluated at various distances, including 40 cm and 33 cm, for both monocular and binocular outcomes. Patient satisfaction was evaluated using the VF-14 questionnaire. Results 72 eyes underwent PanOptix IOLs implantation, and 18 eyes received PanOptix toric IOLs. At 3-month postoperative mark, the mean monocular UDVA, UIVA, and UNVA at 40 cm and 33 cm were −0.02±0.09, 0.00±0.07, 0.02±0.07, and 0.07±0.14 logMAR, respectively, with proportions of visual acuity exceeding 0.1 logMAR were 96.7%, 96.7%, 94.4%, and 74.4%, respectively. The mean binocular UDVA, UIVA, and UNVA at 40 cm and 33 cm were −0.05±0.06, −0.03±0.05, 0.00±0.05, and 0.04±0.07 logMAR, respectively, with proportions of visual acuity exceeding 0.1 logMAR were 97.8%, 100.0%, 100.0%, and 91.1%, respectively. When the near point shifted from 40cm to 33cm, some patients showed a decline for UDVA, but the average reduction was less than one line. The overall VF-14 questionnaire score was 4.02±4.19. Conclusion PanOptix can provide Chinese patients with a full range of satisfying visual acuity, near to 33cm. Though the visual acuity of some patients at 33 cm did not match the level at 40 cm, the gap of one line may not carry clinical significant.

Background To compare clinical outcomes of trifocal intraocular lens in patients with and without prior history of laser in situ keratomileusis (LASIK). Methods A retrospective study included patients who underwent bilateral cataract surgery and PanOptix trifocal intraocular lens (IOLs) implantation. Patients were grouped: Group A for patients with history of LASIK and Group B for patients without history of LASIK. Postoperative outcome measures comprised distance, intermediate, and near visual acuity, manifest refraction, defocus curve, contrast sensitivity, visual quality, patient satisfaction, and the rate of spectacle independence. Results A total of 288 eyes (144 patients) were included: 132 eyes in Group A and 156 eyes in Group B. At 6 months post-surgery, patients of both groups achieved a continuous satisfying visual acuity from 33 cm to distance. 73% of eyes in Group A and 75% of eyes in Group B were within ± 0.50 D of emmetropia ( P > 0.05). The percentages of eyes within ± 1.00 D of emmetropia were 98% for Group A and 96% for Group B ( P > 0.05). The total scores of satisfaction were 52.58 ± 3.46 for Group A and 53.23 ± 3.46 for Group B ( P > 0.05). Most of patients (98% for Group A, 99% for Group B) were able to be spectacle independence for daily living. 53% of patients in Group A and 51% in Group B experiencd mild to moderate negative visual symptoms, which made it a little or moderate difficult to drive at night. Conclusions Cataract patients with and without history of LASIK could safely undergo implantation of the PanOptix IOLs, which results in precise refractive outcomes and satisfactory visual acuity. Although contrast sensitivity decreased and some negative visual symptoms were observed, patients’ satisfaction was generally high due to the high rate of spectacles independence. There were no statistically significant differences between the study groups.

To investigate the visual acuity and satisfaction of patients after Zhang & Zheng's corneal laser-enhanced accommodation refraction Q (ZZ-CLEAR-Q) surgery utilizing differential modulation of binocular longitudinal spherical aberration and determine its clinical significance. Patients and Methods: This prospective observational study enrolled a consecutive cohort of patients with presbyopia who underwent ZZ-CLEAR-Q surgery between December 2020 and January 2023. The study assessed visual acuity, distance-corrected defocus curve, satisfaction, Q factor, manifest spherical equivalent, and primary spherical aberration, among others, at 3 months postoperatively. Additionally, the study conducted a binocular comparison to analyze the clinical significance of setting the different longitudinal spherical aberrations. Results: A total of 232 eyes of 116 patients were included. The binocular uncorrected distance visual acuity was 20/20 for all patients. At 3 months postoperatively, the binocular uncorrected near visual acuity was Jaeger 1 for 96% of the patients and Jaeger 2 for 100% of the patients. Furthermore, 93.1% of the patients expressed satisfaction. The monocular distance-corrected defocus curve revealed that the dominant eyes had significantly better visual acuity at 0 D (P<0.001), while the non-dominant eyes had significantly better visual acuity across various defocus levels except 0 and −0.50 D (All P<0.05). At 3 months, there were no significant differences between the expected and achieved manifest spherical equivalents, corneal Q factor values, and ocular primary spherical aberration values of both groups. Conclusion: Patients with presbyopia who underwent ZZ-CLEAR-Q surgery were likely to achieve normal uncorrected visual acuity and be satisfied. The increased depth of field has clinical significance for assisting near vision.
