TL;DR
Postoperative VF sensitivity improved after all three IOL types, whereas multifocal IOLs, particularly trifocal IOLs, showed higher MS in paracentral and peripheral zones.
Abstract
Purpose
To compare the visual field (VF) outcomes after implantation of monofocal, bifocal and trifocal Intraocular Lenses (IOL) from the same manufacturer platform.
A total of 102 patients (123 eyes) with age-related cataract were divided into monofocal, bifocal, and trifocal IOL groups. Best-corrected visual acuity (BCVA), refraction, Humphrey 30-2 standard automated perimetry (SAP), and defocus curve were assessed preoperatively and 3 months postoperatively. Outcome measures included visual field index (VFI), mean deviation (MD), and pattern standard deviation (PSD), as well as regional mean sensitivity (MS) in 3 predefined visual field regions: central (0°-5°, zone I), paracentral (6°-15°, zone II), and peripheral (16°-30°, zone III).
Results
All three IOL groups showed significant postoperative improvements in BCVA, VFI, MD, PSD, and MS in all zones (P < 0.05). Postoperative MS did not differ significantly among groups in zone I. In zone II, MS was higher in the bifocal and trifocal groups than in the monofocal group, with no significant difference between bifocal and trifocal IOLs. In zone III, MS was highest in the trifocal group, followed by the bifocal and monofocal groups (P < 0.05). Intergroup differences in ΔMS were not significant in zone I but were greater in zone II for bifocal and trifocal IOLs. For zone III, ΔMS was significantly larger in the trifocal group than in the monofocal group.
Conclusion
Postoperative VF sensitivity improved after all three IOL types. Central MS did not differ significantly among groups, whereas multifocal IOLs, particularly trifocal IOLs, showed higher MS in paracentral and peripheral zones.
The subjective and objective visual outcomes after implantation of monofocal, bifocal, and extended depth-of-focus (EDOF) intraocular lenses (IOLs) were compared to compare the subjective and objective visual outcomes after implantation of monofocal, bifocal, and extended depth-of-focus (EDOF) intraocular lenses (IOLs).

The CNWTTx lens results in excellent visual acuities at distance, intermediate, and near, leading to high rates of spectacle independence and patients are subjectively satisfied with their visual outcomes.

PURPOSE
To evaluate visual, refractive, and quality-of-vision outcomes after unilateral cataract surgery or refractive lens exchange (RLE) with implantation of a rotationally asymmetric refractive multifocal intraocular lens (IOL), including the LENTIS Mplus LS-313 MF30 and LENTIS MplusX.
METHODS
Thirty-nine patients who underwent unilateral lens extraction (24 for cataract, 15 for RLE) with LENTIS Mplus multifocal IOL implantation were analyzed. Examinations were performed preoperatively and postoperatively at 1, 3, and 6 months, and at the final follow-up. Distance, intermediate, and near visual acuity, refraction, wavefront aberrations, contrast sensitivity, defocus curves, and Quality of Vision questionnaire scores were assessed.
RESULTS
At the final visit, 60.72 ± 37.75 months postoperatively, mean uncorrected and corrected distance visual acuity were 0.10 ± 0.23 and 0.01 ± 0.08 logMAR, respectively. Mean uncorrected and corrected near visual acuity were 0.10 ± 0.11 and 0.09 ± 0.17 logMAR, respectively. Mean uncorrected intermediate, corrected distance intermediate, and corrected distance near visual acuity were 0.12 ± 0.14, 0.12 ± 0.07, and 0.12 ± 0.15 logMAR, respectively. Defocus curves demonstrated broad functional vision across distance, intermediate, and near ranges. Contrast sensitivity and quality-of-vision outcomes suggested generally mild visual disturbances.
CONCLUSION
Unilateral implantation was well tolerated, with favorable monocular and binocular performance, high refractive predictability, and minimal optical side effects.

This segmental multifocal intraocular lens provides good visual acuity at all distances, particularly providing good intermediate visual acuity and depth of focus, and showed good contrast sensitivity and high spectacle independence with a high degree of patient satisfaction.

Bilateral mix-and-match implantation of EDOF and trifocal IOL implantation showed good visual outcomes for distance, intermediate, and near vision until 12 months, while more than 70% of patients consistently reported that they would recommend the surgery to others.

PURPOSE
Multifocal intraocular lenses (MIOLs) are disadvised among patients with irregular corneas, but the role of subclinical corneal irregular astigmatism on long-term visual outcomes remains poorly elucidated.
SETTING
Keye Eye Center, Seoul, Korea.
DESIGN
Retrospective single-center clinical cohort study.
METHODS
Bilateral implantation of PanOptix MIOL with 3 years follow-up. Eyes were stratified based on total corneal irregular astigmatism (TCIA) in Scheimpflug tomography into low (≤0.15 µm), moderate (>0.15 to <0.30 µm), and high (≥0.30 µm) TCIA groups.
RESULTS
In the cohort of 474 eyes of 237 patients, those with high TCIA had greater prevalence of prior refractive surgery (16% vs 2%; p<0.001), greater spherical aberration (0.45±0.26D vs 0.28±0.10D; p<0.001), and lower central corneal thickness (511±43µm vs 548±30µm; p=0.001) than those with low TCIA. High TCIA resulted in worse uncorrected distance visual acuity (UDVA) at 1-year (0.11±0.10 vs 0.03±0.08 logMAR units; p=0.001) and at 3-years (0.16±0.15 vs 0.04±0.08 logMAR units; p<0.001) compared to low TCIA, despite comparable postoperative refractive outcomes. At 3-years, Strehl ratio (0.024±0.019 vs 0.041±0.027; p=0.001), photopic (1.23±0.14 vs 1.39±0.20; p<0.001) and mesopic AULCSF (0.91±0.16 vs 1.06±0.19; p<0.001) were worse in high TCIA group compared to low TCIA group. Greater preoperative TCIA was associated with poorer age- and sex-adjusted UDVA (B=0.174, 95%CI: 0.101 to 0.248, p<0.001), corrected distance visual acuity (B=0.261, 95%CI: 0.132 to 0.389, p<0.001), and Strehl ratio (B=-0.598, 95%CI: -0.865 to -0.332, p<0.001) at 3-years.
CONCLUSIONS
High preoperative TCIA should be considered as predictive for impaired long-term visual acuity and quality outcomes after MIOL implantation.
