Abstract
PURPOSE To evaluate the optical and aberrometric outcomes of an enhanced monofocal intraocular lens (ISOPure) compared with those of a standard monofocal lens (MicroPure) having the same platform and material. METHODS A prospective, comparative and randomised clinical study. A total of 28 eyes of 28 patients were randomly assigned to either group. Monocular visual acuity (VA) was measured at distance and intermediate under photopic and mesopic conditions. Aberrometry was analysed for 3.0-, 4.0-, 4.5- and 5.0 mm pupils. The contrast sensitivity defocus curve was measured for 3.0- and 4.5-mm pupils, while the modulation transfer function (MTF) and Strehl ratio (SR) were assessed with a double-pass system. All measurements were performed monocularly 3 months after surgery. RESULTS No significant differences were found for distance VA. Under photopic conditions, intermediate VA was better with the ISOPure lens, while no significant differences were found between the lenses under mesopic conditions. Internal and total aberrations were higher for the ISOPure lens. No significant differences were found for corneal aberrations. Additionally, both the contrast sensitivity defocus curve and optical quality showed similar behaviour for each lens, with the MTF cut-off frequency exceeding 30 c/deg in both cases. CONCLUSION The isofocal ISOPure lens enhanced intermediate VA without affecting distance VA under photopic conditions. Moreover, there were no significant differences in visual quality between the ISOPure and MicroPure lenses, despite the former exhibiting higher internal and total aberrations than the monofocal model.

Abstract
PURPOSE To provide the reports of a pilot study to assess the visual acuity (VA) and contrast sensitivity with RayOne enhanced monovision (EMV), a unique nondiffractive enhanced monofocal intraocular lens (IOL) to increase the range of focus. METHODS A retrospective case series study was conducted by analyzing 25 patients (50 eyes) who had bilateral implantation of EMV IOL after cataract surgery. Data collected included biometry, spherical equivalent (SE), and VA for near, intermediate, and distance. Patients were reviewed at 1 day, 1 week, and 1 month after surgery. Contrast sensitivity (CS) was checked at 1 month. RESULTS The study included 14 males (56%). Age of participants was 61.4 ± 7.4 years. Uniocular uncorrected near and distance VA improved from 0.33 ± 0.13 to 0.05 ± 0.07 and from 0.63 ± 0.31 to 0.05 ± 0.10 log of minimum angle of resolution (logMAR) at 1 month (P < 0.001 for both). Binocular uncorrected near and distance VA improved from 0.09 ± 0.18 and 0.14 ± 0.27 to 0.05 ± 0.06 and 0.00 ± 0.09 logMAR, respectively (P < 0.001). SE changed from - 0.23 ± 2.55 to - 0.33 ± 0.46. CS at 3 months was 1.74 ± 0.21. At 1 month, 48 eyes (96%) achieved uncorrected intermediate VA 6/15 (0.4 logMAR) or better. When comparing eyes that had uncorrected intermediate vision of ≥ 0.2 (6/9 or better) to eyes that had < 0.2 logMAR at 1 month, there was no difference between groups with respect to baseline parameters. CONCLUSION The pilot study shows that the nondiffractive EMV IOL is safe, effective, and stable, providing excellent distance and intermediate vision and good near vision.

Abstract
Purpose To evaluate relative visual performance and subjective outcomes after implantation of the TECNIS Eyhance™ intraocular lens (IOL) targeted for bilateral emmetropia or monovision. Methods This was a prospective, single-center randomized, patient-masked trial. Patients were implanted with the enhanced IOL targeted for bilateral emmetropia or slight monovision (-0.75 D in the non-dominant eye). At 3 months the binocular visual acuity (VA) was measured at distance, intermediate and near, along with low contrast VA in photopic and mesopic conditions, and the distance corrected defocus curve. Questionnaires related to spectacle independence, satisfaction, visual symptoms, and functional vision were administered. Results Data from 71 subjects (34 Emmetropia, 37 Monovision) were analyzed. There was no difference in the mean uncorrected distance VA (p = 0.11), but uncorrected intermediate and near VAs were one line better in the Monovision group (p = 0.02 and 0.01, respectively). Mesopic and photopic low contrast VA were similar between groups. There was a trend for less difficulty and higher satisfaction with near and intermediate vision in the Monovision group, but no significant differences in any of the subjective questionnaires. Difficulty reading was the most reported concern in both groups, though 93% of all subjects reported "little" or "no" difficulty with daily activities. Overall, 82% of subjects were "completely" or "very" happy with their lens choice. Conclusion Using this enhanced IOL with slight monovision in the non-dominant eye increased intermediate and near VA with no apparent effect on low contrast distance VA, subjective visual quality, or satisfaction.

Abstract
BACKGROUND The aim of this research was to see if a refractive enhanced monofocal IOL (Eyhance IOL, IOL Abbott Medical Optics, Inc., Santa Ana, CA, USA) can provide better intermediate vision in patients undergoing phaco-vitrectomy due to cataract and epiretinal macular membrane (ERM). METHODS A nonrandomized prospective observational comparative study enrolled patients affected by cataract and ERM undergoing phaco-vitrectomy. A follow up of 6 months was established. Corrected and uncorrected visual acuity of both monocular and binocular types were assessed regarding intermediate and far distances. The CATQUEST 9-SF questionnaire was administered preoperatively and at the last follow-up. RESULTS Twenty-three eyes of twenty-three patients were enrolled, with 11 in the enhanced monofocal group. The uncorrected and corrected distance visual acuity after 6 months was not statistically different. Both monocular and binocular uncorrected intermediate visual acuity after 6 months were higher in the enhanced monofocal group (p < 0.001). The corrected intermediate visual acuity after 6 months was higher in the enhanced monofocal group (p = 0.01). The CATQUEST-9SF questionnaire showed significant differences in the variation between the preoperative condition and six-month postoperative results (p < 0.001). CONCLUSIONS This refractive enhanced monofocal IOL can provide better intermediate vision compared to a standard monofocal IOL in patients undergoing phaco-vitrectomy due to cataracts and ERM. Further studies are necessary to confirm these results.

Abstract
The purpose of this study was to compare the visual performance and optical quality between three new enhanced monofocal intraocular lenses (IOLs). This retrospective study included patients affected by cataracts with corneal astigmatism less than 0.75 D and no ocular comorbidities who underwent cataract surgery with bilateral implantation of Tecnis Eyhance ICB00 (Johnson & Johnson Vision Care, Inc., Jacksonville, FL, USA), Vivinex Impress XY1-EM (Hoya Surgical Optics, Singapore) or IsoPure 123 (PhysIOL, Liege, Belgium) IOLs. Three months postoperatively, monocular and binocular uncorrected and corrected distant, and intermediate and near visual acuities were measured. Binocular defocus curve, photopic contrast sensitivity, Point Spread Function (PSF), low order aberrations (LOAs), high order aberrations (HOAs), objective scatter index (OSI), halo and glare perception were also evaluated. This study included a total of 72 eyes from 36 patients. Visual acuity outcomes, PSF, LOAs, HOAs and OSI were similar between groups. There were no statistically significant differences in terms of photopic contrast sensitivity, halo or glare perception. In patients without ocular comorbidities, the Eyhance ICB00 IOL, the Vivinex Impress IOL and the Isopure IOL-even though based on different optical properties-provided similar results in terms of visual acuity, contrast sensitivity and intraocular aberrations, with no influence on photic phenomena.
