Abstract

Purpose: To assess prospectively the visual outcomes of multifocal and monofocal intraocular lens (IOL) implantation in selected patients with a minimum follow-up of 18 months. Setting: Department of Ophthalmology, National Health Service (INSALUD), Puerta de Hierro University Clinic, Madrid, Spain. Methods: This prospective study comprised two groups of 50 eyes each: one with AMO Array multifocal IOLs and the other with monofocal IOLs. Main outcome measures were Snellen and Regan 96% distance visual acuities; Jaeger and decimal near acuities; Regan contrast sensitivity test at 96, 50, 25, and 11%; brightness acuity test (BAT) on distance acuity at Regan 96%; depth of focus measured with the Regan 96% distance test; defocusing from +3s to -4s; subjective evaluation of optical side effects. Results: The differences between groups in mean distance vision and BAT results were not statistically significant. Contrast sensitivity results at 96 and 50% were similar, but there were significant differences of 0.94 and 1.14 lines on the 25 and 11% charts, respectively (P<.01). Near vision without addition in the multifocal group was significantly better and depth of focus significantly wider than in the monofocal group (P<.001). Conclusion: With appropriate patient selection, the AMO Array IOL provided distance acuity and contrast sensitivity similar to that of the monofocal IOLs and excellent intermediate vision. Near vision, without spectacles, with the multifocal lens was functionally acceptable although short of refractive power for best acuity results.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-04-25:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 11.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 11 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 3.

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
