“…In another comparative study published in the same year, Zhu et al found 0.09, 0.15, and 0.13 logMAR in their AT LISA tri patients at −1D, −2D, and −3D, respectively. 20 Those values are nearly identical to the ones reported by Torky et al, 19 showing a good agreement between the VA of the two cohorts. Our simulated polychromatic VA assessment for the AT ELANA yielded logMAR values of 0.09, 0.10, and 0.11 at defocus levels of −1D, −2D, and −3D, respectively.…”

The optical function of a novel refractive-diffractive trifocal intraocular lens (IOL) was tested in vitro to provide preclinical metrics that predict postoperative performance and may guide patient selection. Methods: Fundamental optical characteristics of a trifocal hydrophobic-acrylic IOL with a C-loop haptic configuration (AT ELANA 841P, Carl Zeiss Meditec) were assessed using a fully automated optical test device under both monochromatic and polychromatic conditions combined with increased or compensated spherical aberration (SA). The area under the modulation transfer function (MTFa) was calculated across a defocus range from +1D to −3.5D and used to simulate visual acuity (VA). A polychromatic point spread function (PSF) was employed to assess the light distribution and identify photic phenomena. Results:The highest MTFa values were obtained under monochromatic conditions using an SA-neutral corneal model. Nevertheless, after introducing SA and polychromatic light, the IOL performance remained good. Simulated VA values were 0.00 logMAR for distance, 0.1 logMAR at 100 cm, and progressively improving to 0.05 logMAR at 40 cm from the intermediate point. The light-spread analysis confirmed halos around the PSF center, which is a characteristic of trifocal technology. Conclusion:AT ELANA 841P demonstrated good optical performance across various distances, independently of spectral and SA conditions, resulting in good simulated VA. Although light spread resembles standard trifocal IOLs, clinical studies are essential to confirm these laboratory results.

“…Clinical application of EDoF IOLs may also increase because it can provide continuous vision over a range of distances, is closer to human eye perception, and has fewer visual disturbances. A retrospective comparative study by Zhu et al found that EDoF IOLs had the best quality of vision and the least photic disturbance compared to non-EDoF MfIOL; however, near VA was worse than that of conventional types 71 . Similarly, Karuppiah et al found that the EDoF group had better contrast sensitivity than the trifocal non-EDoF IOL group.…”

Background Premium intraocular lenses (PIOLs), particularly those using multifocal, extended depth of focus (EDoF) and toric technologies, have been in clinical use for decades, giving countless cataract patients the ability to see the world clearly again. To explore the development process, research status and future development trends of PIOLs, we explored research on PIOLs from the past 22 years through bibliometrics. Methods The literature search was performed on the Web of Science and included PIOL studies published between 2000 and November 2022. The retrieved literature was collated and analyzed by R-tool's Bibliometrix package, CitNetExplorer, CiteSpace and other software. Results We obtained a total of 1801 articles about PIOLs, most of which were published in Spain and the United States. The organization that published the most articles was the University of Valencia in Spain. Alió JL, and Montés-Micó R, from Spain were the most influential authors in this field. The Journal of Cataract and Refractive Surgery and Journal of Refractive Surgery were the core journals for this field; the top 10 cited articles mainly focus on postoperative satisfaction with multifocal IOLs and postoperative results of toric IOLs. Through a key word analysis, we found that trifocal IOLs, astigmatism and EDoF IOLs are the most discussed topics at present, and the importance of astigmatism and the clinical application of the new generation of PIOL are the emerging research trends. In addition, we found that researchers are not only focusing on the application of cutting-edge technology but also paying increasing attention to patients' subjective satisfaction. Conclusion Bibliometric analysis can effectively help to identify multilevel concerns in premium intraocular lens (PIOL) research and we found that in the past 2 decades, the research of PIOL has made rapid development and gradually matured, countless cataract patients can regain excellent visual quality and improve their quality of life after surgery. The current research hotspots regarding PIOL are the application of EDoF IOL as well as trifocal IOL and its toric models and the development of new types of PIOLs.

“…For instance, Tañá-Sanz et al [ 14 ] reported a mean pupil size of 2.4 mm in a sample of patients with a mean age of 72 years, and Sun et al [ 15 ] reported a mean pupil size of 3.3 mm in a sample of patients with a mean age of 66 years. Other authors have also used Pentacam for reporting PP in their studies with mean pupil sizes in the range of 2.4 to 3.3 mm depending on the mean age of the sample [ 16 , 17 , 18 , 19 ]. As PW now measures MP, it is expected that future studies will also include the MP with this device; therefore, it is important to know how the measurement agrees with other previous devices such as the K5M.…”

The purpose of this study was to evaluate the agreement between three methods for measuring pupil size in patients implanted with multifocal intraocular lenses (MIOLs): Keratograph 5M (K5M), Pentacam AXL Wave (PW), and a simple hand ruler. Sixty-nine subjects implanted with MIOLs and measured at the three-month follow-up visit were included in this retrospective analysis. K5M and PW were used to measure the photopic (PP) and mesopic (MP) pupil sizes, and a hand ruler was used to measure the pupil under environmental light conditions (135 lux). The Bland–Altman method with its limits (LoAs) was used to assess the agreement. The median PP was 2.8, 2.95, and 3 mm for K5M, PW, and the ruler, respectively (p < 0.05). Differences in PP were statistically significant for all paired comparisons (p < 0.0005) except between PW and the ruler (p = 0.44). The LoAs for the difference in PP between K5M and PW was 0.63 mm. The mean difference for MP between K5M and PW was 0.04 mm (p = 0.34) with LoAs of 0.72 mm. MP measured with K5M and PW could be considered interchangeable, although a correction of −0.3 mm (IC95%: −0.23 to −0.39) should be applied to PP measured with PW to attain the K5M mean.
