“…Objective in vitro studies were carried out in different eye models, which may be the reason for dissimilarities in the proposed formulae, but still, they illustrate well the high correlation between MTFA-based metrics and clinically measured VA. Figure 6 shows TF MTFA curves based on measurements in our optical bench. According to the published results of clinical trials, Lentis Mplus, AT Lisa and PanOptix allow to get VA better than 0.2 logMAR for defocus up to 3.0-3.5 D [19,20,28,30,32,38]. In the case of the Tecnis Symfony, the same VA values correspond to the smaller defocus up to 2-2.5 D [31,34].…”

This work presents the first models of light sword intraocular lenses (LS IOLs) with angularly modulated optical power. We performed an experimental, comparative study with multifocal and extended depth of focus intraocular lenses, which are available on the market. The measurements conducted in an original optical bench were utilised for an analysis of point spread functions, elongated foci, modulation transfer functions and the areas defined by them. The LS IOL models perform homogeneous imaging in the whole range of designed defocus. The proposed concept of extended depth of focus seems to be promising for the development of presbyopia-correcting intraocular lenses capable of regaining fully functional vision.

“…Despite of its bifocality, Lentis Mplus can restore distance, intermediate and near visual function with substantially reduced photic phenomena such as glare and halos [15,16]. Different papers about Lentis Mplus have been published, including reports on in vitro results and clinical outcomes [17][18][19][20][21].…”

“…Since the CONCERTO study used monovision approach with multifocal IOL [9], to overcome the limitations of available IOLs, efforts have been made to expand the range of vision by implanting different types of multifocal IOLs in each eye of a subject [10]. Several studies have reported a good range of vision after bilateral mixand-match implantation of multifocal IOLs [2,11,12]. However, studies that evaluate clinical outcomes after implantation of diffractive multifocal IOLs with different add powers are scarce.…”

Background: To evaluate the clinical outcomes of bilateral mix-and-match implantation of diffractive multifocal intraocular lenses (IOLs) with different add powers. Methods: We retrospectively reviewed the medical records of 18 patients who underwent bilateral mix-and-match implantation of diffractive multifocal IOLs with different add powers. Multifocal IOLs with add powers of + 2.75 diopters (D) and + 4.00 D were implanted into the patients' dominant and nondominant eyes, respectively. At 1 and 3-month postoperatively, monocular and binocular visual acuity was measured using logMAR charts and manifest refraction was performed. Specifically, logMAR charts were used to measure uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), and corrected distance visual acuity (CDVA). Defocus curves, contrast sensitivity, and patient satisfaction were assessed at 3-month postoperatively. Results: Binocular logMAR measurements (mean ± standard deviation) at 3-month postoperatively were 0.01 ± 0.04 (UDVA), 0.16 ± 0.05 (UIVA), and 0.11 ± 0.07 (UNVA). Postoperative spherical equivalent was − 0.43 ± 0.35 D and − 0.39 ± 0.21 D in the dominant and nondominant eyes, respectively. Defocus curves showed significant differences between − 1.50 and − 4.00 D among binocular, dominant, and nondominant eye measurements, except between − 2.50 and − 3.00 D. Eyes implanted with + 2.75 and + 4.00 D IOLs showed good contrast sensitivity under photopic and mesopic conditions. Over 80% of patients reported high satisfaction with their near vision. Conclusions: Bilateral mix-and-match implantation of diffractive multifocal IOLs with add powers of + 2.75 D and + 4.00 D showed good near, intermediate, and far vision.

Comparison of Visual Function after Implantation of Inferior Sector-Shaped Intraocular Lenses: Low-add +1.5 D vs +3.0 D

Abstract: 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.
