PURPOSE OF REVIEW:The manuscript presents a review of recently published studies reporting objective and subjective outcomes and preoperative considerations of asymmetrical multifocal intraocular lenses (IOLs). RECENT FINDINGS:Current publications suggest that asymmetrical multifocal IOLs provide good, distance, intermediate and near vision for cataract and clear lens extraction patients. The contrast sensitivity achieved is similar to monofocal IOLs. Photopic phenomenon such as glare and halos has been reduced through the use of these IOLs leading to better patient satisfaction. Centration plays a critical role and the lack of a gold standard assessment tool has led to a minority of patients experiencing lower quality of vision and side-effects such as glare and hazy vision. The frequency of dissatisfied patients can be minimized by appropriate patient selection. This is achieved by assessing pupil parameters which guides the surgeon to align the IOL accordingly. SUMMARY:Asymmetric multifocal IOLs provide the surgeon with an IOL that achieves excellent visual and refractive outcomes enabling patients to see clearly at a range of distances. Subjectively patients report low levels of photopic phenomena and high levels of spectacle independence resulting in high overall patient satisfaction.

PURPOSE:To compare visual function after implantation of multifocal Lentis comfort LS-313 MF 15 (group 1) or Lentis M plus LS-313 MF 30 (group 2) intraocular lenses (IOLs). METHODS:Patients between 49 and 76 years of age who received monocular cataract surgery with multifocal IOL implantation were analyzed. Patients were evaluated preoperatively and for 5 months postoperatively for distance, intermediate, and near visual acuities, and static photopic and mesopic contrast sensitivity. A satisfaction questionnaire was administered 5 months after surgery. RESULTS:Group 1 comprised 21 eyes and group 2 contained 34 eyes. Both groups had a statistically significant improvement in uncorrected and corrected distance visual acuities postoperatively (p<0.01). Uncorrected visual near acuity at 40 cm was better in group 2 (1 month: p = 0.013; 5 months: p = 0.051). Uncorrected intermediate visual acuity at 70 cm was better in group 1 (1 month: p = 0.060; 5 months: p = 0.044). No significant differences in contrast sensitivity were observed between the groups. Glare and halo symptoms were better in group 1 (glare: p = 0.044; halo: p = 0.029). CONCLUSIONS:Inferior sector-shaped, near-addition IOLs with lower add powers (+1.5 D) provide good vision over longer working distances and show fewer glare and halo symptoms.

DOI :10.1038/s41598-022-24123-7
We compared the visual performance of a diffractive bifocal intraocular lens (IOL) with + 4.0 D near addition (ZMB00 [Johnson & Johnson Surgical Vision]) and a rotationally asymmetric refractive IOL with + 1.5 D near addition (LS-313 MF15 [Teleon Surgical BV]) 10 weeks after cataract patients' last surgery for bilateral ZMB00 or LS-313 MF15 implantation between 2011 and 2020, with the lenses of each eye implanted within 3 months of each other. The ZMB00 and LS-313 MF15 groups comprised 1326 eyes of 663 patients (age: 67.0 ± 7.8 years; females/males, 518/145) and 448 eyes of 224 patients (73.6 ± 7.0 years; females/males, 125/99), respectively. A linear mixed-effects model using data for both eyes, with strict adjustments for sex, age, subjective refraction spherical equivalent, subjective refraction cylinder, corneal astigmatism, axial length, corneal higher-order aberrations, and pupil diameter, ensured statistical validity. Compared to LS-313 MF15, ZMB00 achieved significantly superior uncorrected near visual acuity, reduced higher-order aberrations (ocular/internal, scaled to a 4-mm pupil; Wavefront_4_post_Ocular_Total Higher-Order Aberration/Third/Fourth/Trefoil/Coma/Tetrafoil/Spherical, Wavefront_4_post_Internal_Astigmatism/Total Higher-Order Aberration/Third/Trefoil/Coma/Tetrafoil/Spherical), and superior distance and near spectacle independence (p < 0.00068, Wald test). Contrast sensitivity, measured without (visual angle of the test target: 6.3°/4.0°/2.5°/1.6°/1.0°/0.7°) or with glare (4.0°/2.5°/1.6°/1.0°/0.7°), was significantly better in the LS-313 MF15 than the ZMB00 group (p < 0.00068, Wald test).

4. [Observation of visual quality after implantation of a rotational asymmetric refractive intraocular lens with a low addition region using the micromonovision design].
期刊:[Zhonghua yan ke za zhi] Chinese journal of ophthalmology

DOI :10.3760/cma.j.cn112142-20230220-00060
To investigate the effects of the application of a low addition refractive multifocal intraocular lens (IOL) using the micromonovision design in the non-dominant eye with different degrees of preset myopia on the visual acuity, visual function and visual quality after bilateral cataract surgery. In this randomized controlled trial, patients who were proposed to undergo bilateral phacoemulsification combined with rotational asymmetric refractive IOL (MF15 IOL) implantation at the First Affiliated Hospital of Zhengzhou University between September 2020 and August 2022 were included. All patients were divided into three groups using the random number method. The target refraction of the IOL in the dominant eye was 0.00 D. Non-dominant eyes were given different preoperative IOL reserve refractions, with the reserved near additional degree>0.20 D and≤0.40 D as the low addition,>0.40 D and≤0.60 D as the medium addition, and>0.60 D and≤0.80 D as the high addition. We compared uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA) and uncorrected near visual acuity (UNVA) of monocular and binocular eyes at 1 day, 1 month and 3 months postoperatively in the 3 groups of patients. Furthermore, the contrast sensitivity, stereopsis, defocus curves and visual quality questionnaire results of binocular eyes were compared at 3 months postoperatively. The statistical methods mainly used were chi-square test, two-factor repeated measures ANOVA, one-way ANOVA, LSD test, Kruskal-Wallis test, and paired -test. A total of 110 patients (220 eyes) were enrolled in the study, including 48 males and 62 females, with an average age of (59.74±9.38) years. There were 40 patients (80 eyes) in the low additional degree group, 37 patients (74 eyes) in the medium additional degree group, and 33 patients (66 eyes) in the high additional degree group. The differences in distance, intermediate and near visual acuity of the dominant eyes among the three groups were not statistically significant at different measurement timepoints postoperatively (>0.05). The differences in intermediate and near visual acuity of the non-dominant eyes were also not statistically significant (>0.05) among the three groups. In contrast, at 3 months, the UDVA of the non-dominant eyes in the low additional degree group (0.04±0.06) and medium additional degree group (0.04±0.07) was significantly higher than that in the high additional degree group (0.08±0.09) (=4.776, =0.011, bias =0.086). There was no statistically significant difference in binocular uncorrected distance, intermediate and near visual acuity among the three groups at different postoperative timepoints (>0.05). The binocular UDVA, UIVA and UNVA (logMAR visual acuity) at 3 months postoperatively were -0.04±0.04, 0.03±0.08, 0.10±0.13 in the low addition group, -0.01±0.05, -0.02±0.06, 0.09±0.10 in the medium addition group, and 0.02±0.07, 0.01±0.09, 0.16±0.11 in the high addition group. At 3 months postoperatively, the binocular contrast sensitivity of the low additional degree group was significantly higher than that of the high additional degree group (<0.05), except that there was no significant difference at the spatial frequency of 6 cycles per degree in the absence of glare (>0.05). The binocular contrast sensitivity of the medium additional degree group was significantly higher than that of the high additional degree group at the spatial frequencies of 6 and 18 cycles per degree in the glare condition (<0.05). The difference in the binocular contrast sensitivity between the low and medium additional degree groups did not reach statistical significance (>0.05). The peak of the binocular defocus curve in the three groups was significantly wider than that in the monocular eyes, and the decline trend was more gentle, with no trough in the middle, and the visual acuity could be maintained above 0.2 (logMAR visual acuity) in the 0.00 D to -3.00 D defocus range. There was no significant difference in the postoperative near stereopsis results among the three groups (>0.05), with the percentage of near stereopsis sharpness≤60″ reaching 90.00% (36/40), 89.19% (33/37) and 78.79% (26/33), respectively. The proportions of VF-14 scores≥90 in the postoperative questionnaire were 90% (36/40), 91.89% (34/37) and 81.82% (27/33) for the low, medium and high additional degree groups, respectively. The differences in the probability of photic phenomena and spectacles-independent rate were not statistically significant (>0.05). The use of micromonovision design for bilateral implantation of a rotational asymmetric refractive MF15 IOL, with the non-dominant eye reserved for different near additional degrees, can enable cataract patients to have significantly improved binocular full-range vision, visual function and visual quality. When the degree of reserved near additions in the non-dominant eye preoperatively is>0.20 D and≤0.60 D, it can ensure sufficient binocular UDVA, UIVA and UNVA after surgery, and meanwhile help to obtain superior contrast sensitivity and stereopsis, as well as a satisfactory spectacles-independent rate and low incidence of photic phenomena.

5. Clinical Outcome of Lentis Comfort Intraocular Lens Implantation.
期刊:Journal of Nippon Medical School = Nippon Ika Daigaku zasshi
日期:2020-09-30
DOI :10.1272/jnms.JNMS.2021_88-504
PURPOSE:To evaluate visual outcome and patient satisfaction following Lentis Comfort intraocular lens (IOL) implantation. METHOD:This retrospective case series examined 68 eyes of 41 patients (mean age 72.0 ± 8.1 years) who underwent Lentis Comfort (LS-313 MF15, Oculentis GmbH, Berlin, Germany; Santen, Osaka, Japan) implantations. Patients were evaluated for visual acuity (VA) at several distances (0.3, 0.5 and 5 meters), refractive error, defocus curve and contrast sensitivity, in addition to answering a questionnaire on photic phenomena, visual discomfort and patient satisfaction. RESULTS:Uncorrected visual acuity was 0.05 ± 0.13 (logMAR) for distance, 0.23 ± 0.17 (logMAR) for intermediate, and 0.52 ± 0.20 (logMAR) for near. Defocus curve showed the binocular visual acuity attained was almost 20/20 within the range of +0.5 D to -1.5 D. Contrast sensitivity was within the normal range. The Lentis Comfort IOL tolerated astigmatism to some extent. Patient age could potentially be related to uncorrected visual acuity. Questionnaire results showed almost all patients were satisfied with Lentis Comfort IOL implantation. CONCLUSION:Lentis Comfort IOLs provided better visual function at far and intermediate distances.

6. One-year clinical evaluation of rotationally asymmetric multifocal intraocular lens with +1.5 diopters near addition.
We conducted a one-year prospective, multicenter study to assess clinical outcomes after implantation of segmented, rotationally asymmetric multifocal intraocular lenses (IOLs) with +1.5 diopters (D) near addition. In this phase III clinical trial, 120 eyes of 65 patients undergoing phacoemulsification and implantation of Lentis Comfort LS-313 MF15 (Oculentis GmbH) were included. The ophthalmological examinations were performed before and 1 day, 1 week, 1, 3, 6, 9, and 12 months after surgery. Uncorrected (UDVA) and corrected (CDVA) distance visual acuity, uncorrected (UIVA) and distance-corrected (DCIVA) intermediate visual acuity at 70 cm, and uncorrected (UNVA) and distance-corrected (DCNVA) near visual acuity at 30 cm were measured. A defocus curve was obtained and patients were asked about the severity of photic phenomena. Postoperative distance and intermediate visual acuity was excellent, with UDVA, CDVA, UIVA, and DCIVA of approximately 20/20, 20/16, 20/25, 20/25 were attained, respectively. The level of near visual acuity was lower; UNVA and DCNVA remained at around 20/60 and 20/70, respectively. The defocus curve indicated that postoperative uncorrected visual acuity of 20/25 and 20/40 was obtained at as close as 67 cm and 50 cm, respectively. Contrast sensitivity was within the normal range, with a minimal level of subjective symptoms and high patient satisfaction. The rotationally asymmetric multifocal IOLs with +1.5 D near addition provided excellent distance and intermediate vision, but near vision was not enough for reading small prints. Contrast sensitivity was high, with very low incidences of photic phenomena and a high level of patient satisfaction.

7. Surgical outcome comparisons of multifocal IOLs of Lentis Comfort LS-313 MF15 and Tecnis Eyhance DIB00V.
期刊:International journal of ophthalmology
日期:2023-12-18
DOI :10.18240/ijo.2023.12.12
AIM:To compare the surgical outcomes of a multifocal intraocular lens (IOL; Lentis Comfort LS-313 MF15) with those of an enhanced monofocal IOL (Tecnis Eyhance DIB00V). METHODS:This retrospective study included patients who underwent cataract surgery with LS-313 MF15 or Eyhance IOL implantation. Data regarding patient demographics, surgical records, and ophthalmic examination before the cataract surgery and one and three months postoperatively were collected. Visual acuities, refractive values, defocus curves, contrast sensitivities and subjective symptoms were evaluated. RESULTS:Among the 71 eyes (47 patients) included in this study, 32 eyes (20 patients) underwent LS-313 MF15 IOL implantation, and 39 eyes (27 patients) underwent Eyhance IOL implantation. No significant differences were observed in age, axial length, or refractive error between the two groups preoperatively. Furthermore, the distance-corrected and uncorrected distance visual acuities one month postoperatively did not differ between the groups, and both groups had sufficient visual acuities at the distances of 5, 1 m, 70, 50, and 30 cm. Other ophthalmic data, including subjective symptoms based on the 14-item Visual Function Index Questionnaire, monocular defocus curves, contrast sensitivities, and halo and glare, did not differ between the groups three months postoperatively. Moreover, both groups had good outcomes. The spherical equivalent one month postoperatively was significantly myopic in the LS-313 MF15 group compared with that in the Eyhance group (=0.033); however, this difference was not observed three months postoperatively (=0.471). CONCLUSION:Comparison of the surgical outcomes of LS-313 MF15 with those of Eyhance with different optical properties reveal that both IOLs show good postoperative outcomes, with no significant differences being noted between the two IOLs.

8. Deposit Effects on Plate-haptic Rotationally Asymmetric Refractive Multifocal Intraocular Lens with +1.5D Addition Power.
期刊:The Tokai journal of experimental and clinical medicine
日期:2023-12-20
OBJECTIVE:To evaluate the optical performance of plate-haptic rotationally asymmetric refractive multifocal intraocular lenses (IOLs) with +1.5 D addition power by reproducing calcium deposition using rabbit eyes. METHODS:Five IOLs (LS-313 MF15 [Santen/Teleon], W-60R [Santen], NS1 [KOWA], SY60WF [Alcon], and NS-60YS [NIDEK]) with varying water content were randomly implanted in rabbit eyes. Cell proliferation in the lens capsule and deposits on the IOL surface were confirmed with a slit lamp. The surface deposits were stained with alizarin red, and IOL transmittance was measured with a spectrophotometer. IOL storage solutions were analyzed using inductively coupled plasma mass spectrometry to confirm the presence of calcium. RESULTS:Slit-lamp observations revealed abundant cellular proliferation on all IOLs. Granular deposits, unlike proliferating cells, were observed on LS-313 MF15 lenses two months after surgery, increasing over time, and stained red. The transmittance of LS-313 MF15 decreased in correlation with the stained area. Calcium was detected in all IOL storage solutions; however, deposits were confirmed only on the LS-313 MF15 surface, indicating decreased transmittance. CONCLUSION:These findings can facilitate predicting deposition on IOLs in clinical settings and selecting IOL materials for long-term stability. The long-term use of LS-313 MF15 IOLs requires further verification to avoid post-surgical extraction.

9. [In Vitro Evaluation of the Optical Quality of Segmental Refractive Multifocal Intraocular Lenses].
期刊:Klinische Monatsblatter fur Augenheilkunde
日期:2017-11-08
DOI :10.1055/s-0043-119993
OBJECTIVES:In customised patient care, it is important to know the optical quality of different intraocular lenses (IOL). In this study, the optical quality of three segmental intraocular lenses were compared. MATERIALS AND METHODS:The LENTIS Comfort LS-313 MF15, LENTIS Mplus X LS-313 MF30 and LENTIS High Add IOL LS-313 MF80 (Oculentis, Berlin, Germany) with a far power of + 21 D were analysed at the optical bench OptiSpheric IOL PRO (Trioptics GmbH, Wedel, Germany). The lenses have almost the same optical design but differ in the power of the near segment. The MF15 has a + 1.5 D addition to improve vision in intermediate distances, the MF30 has a near addition of + 3 D and the MF80 has a near addition of + 8 D. The modulation transfer function area (MTFa) and the Strehl ratio were examined for apertures of 3 mm (photopic) and 4.5 mm (mesopic). RESULTS:The MTFa values for the far focus are 33.34/30.80/51.53 (MF15/MF30/MF80) with an aperture of 3 mm and 25.38/22.52/43.15 for 4.5 mm. The MTFa values for the intermediate focus are 29.85/16.21/6.25 for a 3 mm aperture and 23.92/8.05/3.08 for 4.5 mm. The MTFa values for the near focus are 9.75/21.49/33.12 for an aperture of 3 mm and 4.95/22.70/31.68 for 4.5 mm. The Strehl ratio of the far focus is 0.34/0.30/0.52 for an aperture of 3 mm and 0.24/0.22/0.43 for 4.5 mm. For the intermediate focus, the Strehl ratio is 0.30/0.17/0.07 for an aperture of 3 mm and 0.24/0.08/0.03 for 4.5 mm. The Strehl ratio of the near focus is 0.10/0.22/0.33 for an aperture of 3 mm and 0.05/0.23/0.32 for 4.5 mm. CONCLUSION:We confirmed that the addition influences the optical quality of segmental bifocal intraocular lenses. For the far focus, the results of the MF15 and MF30 are similar. In intermediate distances, the MF15 achieves the best results. For near distances, the MF30 achieves better optical values than the MF15. The lens MF80, which has been designed for patients with maculopathies, achieves good results for far and near distances.

10. Comparative analysis of visual quality between unilateral implantation of a trifocal intraocular lens and a rotationally asymmetric refractive multifocal intraocular lens.
期刊:International journal of ophthalmology
日期:2022-09-18
DOI :10.18240/ijo.2022.09.08
AIM:To compare visual quality after unilateral cataract surgery with implantation of trifocal intraocular lens (IOL) and asymmetric refractive multifocal IOL. METHODS:The prospective nonrandom, comparative study consisted of 60 eyes of 60 patients suffering unilateral cataract surgery with implantation of two different IOLs: AT LISA tri 839MP (30 eyes; Carl Zeiss Meditec, Germany) and LS-313 MF30 (30 eyes; Oculentis GmbH, Germany). Visual acuity, refractive outcome, contrast sensitivity, defocus curves, quality of vision, and optical phenomena were evaluated at 3mo postoperatively. RESULTS:There were no statistical differences between groups in uncorrected distance visual acuity (=0.13) and uncorrected near visual acuity (=0.54). In contrast, uncorrected intermediate visual acuity was better in trifocal group compared to the refractive multifocal group (=0.02). No significant statistical between-group difference was detected in cylinder (=0.43). Compared to trifocal group, spherical refraction and spherical equivalent in refractive multi focal group were more myopic (<0.01). Under photopic conditions, no significant statistical differences were found between groups in contrast sensitivity at 3 and 6 cycles per degree (cpd). The refractive multifocal group performed better at 12 and 18 cpd than the trifocal group (=0.01, =0.034, respectively). The questionnaires of quality of vision and optical phenomena showed no differences between groups. CONCLUSION:Trifocal IOL is superior to refractive multifocal IOL in intermediate visual acuity. Rotationally asymmetric refractive multifocal IOL is more myopic in automated refraction and significantly better for the photopic contrast sensitivity at high frequency.

DOI :10.1155/2022/5645752
Purpose:To investigate the benefits of multifocal lens in patients with high myopic cataract and compare the clinical effects between AT LISA tri 839MP and MPlus LS-313 MF30 intraocular lenses (IOLs) in high myopic eyes. Methods:This retrospective cohort study analyzed 60 eyes with axial length >26 mm in 40 patients. Thirty eyes were implanted with MF30, and the remaining 30 eyes were implanted with 839MP. Postoperative uncorrected distance visual acuity (UDVA), best corrected distance visual acuity (BCDVA), uncorrected intermediate visual acuity (UIVA) and uncorrected near visual acuity (UNVA), defocus curve, modulation transfer function (MTF) curve, Strehl ratio (SR), and complications were compared between the two groups. Results:All vision outcomes were significantly improved in both groups ( < 0.05). There was no significant between-group difference in UDVA at 1 and 3 months postoperatively ( > 0.05). However, UIVA and UNVA were significantly better in the 839MP group ( < 0.05). The VF-14 score, especially for near vision quality, was significantly higher in the MF30 group (2.2 ± 0.9 vs. 0.8 ± 0.7; ≤ 0.001). The SR of both groups significantly increased postoperatively ( < 0.05). All the 3-month MTF curve values (MTF 10 total, MTF 10 internal, MTF 30 total, and MTF 30 internal) were significantly better in the 839MP group ( < 0.05). Meanwhile, all the high-order aberration values (coma, spherical aberration, and trefoil) were significantly greater in the MF30 group ( < 0.05). Conclusion:Multifocal IOL implantation achieves good quality of distance, intermediate, and near vision in patients with high myopia, improving their quality of life. Both 839MP and MF30 IOLs can provide good distance vision, but 839MP performs better in near and intermediate vision. However, for some patients with an extra-long optic axis, MF30 may be a good choice because of its wider range of degrees.

Background:To compare the visual performance of MF30 asymmetric refractive multifocal intraocular lenses (MIOLs) with ZMB00 all optic zone diffractive MIOLs. Methods:This is a prospective study. Patients that underwent phacoemulsification were divided into two groups according to the type of MIOLs used: 35 patients were implanted with asymmetric refractive MIOLs and 35 patients with all optic zone diffractive MIOLs. Visual acuity (VA), refraction, defocus curves, objective optical quality, and a questionnaire evaluating quality of life were measured at 3 months postoperatively. Results:There were no significant differences between the two groups in uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), best-corrected distance visual acuity (BCDVA), or distance-corrected near visual acuity (DCNVA). However, the uncorrected intermediate VA was 0.24±0.10 in the refractive group and 0.31±0.13 in the diffractive group (P<0.05), and the distance-corrected intermediate VA was 0.22±0.09 in the refractive group and 0.31±0.14 in the diffractive group (P<0.05). Defocus curves showed two peaks of maximum vision in both groups. However, the curve between the two peaks in the refractive group was smoother than that of the diffractive group. The modulated transfer function cut-off frequency was 22.74±12.29 c/d in the refractive group and 30.50±10.04 c/d in the diffractive group (P<0.05). The Optical Quality Analysis System (OQAS) values 100% (OV100%) was 0.75±0.41 in the refractive group and 1.02±0.34 in the diffractive group (P<0.05), while the OV20% was 0.52±0.34 in the refractive group and 0.71±0.25 in the diffractive group (P<0.05). There was no significant difference between the two groups in overall satisfaction, spectacle independence ratio, or visual interference phenomenon. Conclusions:Both MIOLs achieve good VA at distance and near vision. Oculentis MF30 showed better intermediate VA, and Tecnis ZMB00 appears to have better objective visual quality.

13. Long-term Prevalence of Opacification of a Hydrophylic Acrylic Rotationally Asymmetric Refractive Multifocal Intraocular Lens.
期刊:Journal of refractive surgery (Thorofare, N.J. : 1995)
日期:2024-02-01
DOI :10.3928/1081597X-20240115-01
PURPOSE:To determine the prevalence of opacification of a hydrophylic intraocular lens (IOL) with hydrophobic coverage and the percentage of explantations required, determining possible risk factors associated with these opacifications. METHODS:This ambispective study enrolled 575 eyes of 296 patients (age 36 to 87 years) that underwent cataract surgery between 2010 and 2017 with implantation of different models of Lentis Mplus IOLs: LS-312-MF30, LS-313-MF15, LS-313-MF30, LU-313-MF30, and LU-313-MF30T (Oculentis GmbH). Visual, refractive, and slit-lamp biomicroscopic changes were evaluated in a long-term follow-up. The percentage of cases with IOL opacification and the percentage of cases in which IOL explantation was required due to such opacifications were calculated at each visit. Five of the explanted IOLs from this series could be analyzed by scanning electron microscopy (SEM-EDX). RESULTS:IOL opacification developed in 63 eyes (11.0%). With 95% confidence, the prevalence of IOL opacification was between 842 and 1,401 cases per 10,000 eyes. The time elapsed between surgery and the presence of IOL opacification ranged between 0 and 9.3 years (mean: 4.7 ± 2.2 years). No significant differences in terms of IOL opacification rate were found according to gender ( = .378). No significant differences were found in arterial hypertension, diabetes, hypothyroidism, or hyperthyroidism rates between eyes with or without IOL opacification ( ≥ .053). IOL explantation was needed in 9 eyes (1.57%). SEM-EDX analysis confirmed the presence of rough areas on the IOL surface containing different components, such as calcium, phosphorous, copper, or nitrogen. CONCLUSIONS:The prevalence of opacification with time in Lentis Mplus IOLs is high, with no systemic risk factors associated with this complication, suggesting that it may be attributable to the material and/or the manufacturing process. .
