“…). Vega et al ., demonstrated in an optical bench study that diffractive multifocal IOLs show, at their foci, secondary out‐of‐focus images, from which halos originate and whose characteristics depend on the lens design and pupil size. However, the perception of these halos by the three IOL groups evaluated was not significantly different.…”

“…1 Visual disturbances such as halos or glare have been reported following implantation of multifocal IOLs. [1][2][3][4] The frequency and intensity of these undesired visual disturbances, despite the correction of the refractive error, may condition final patient satisfaction and consequently the impact of the surgery on patient quality of life. 5,6 For this reason, clinical comparative studies evaluating different types of multifocal IOLs should also include in their examination protocols tests for evaluating the visual quality, patient satisfaction and the impact on patient quality of life.…”

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.Trial registration: Clinical Research Information Service[Internet]; Osong(Chungcheongbuk-do): Korea Centers for Disease Control and Prevention, Ministry of Health and Welfare (Republic of Korea), KCT0003945, Registered 20 May 2019 – Retrospectively registered, https://cris.nih.go.kr/cris/search/search_result_st01_kren.jsp?seq=13946&sLeft=2&ltype=my&rtype=my

“…Despite the excellent technology, photopic phenomena can be generated by the overlapping of images, such as decrease image quality, lower contrast sensitivity and halo or glare perception. These are factors that can lead to dissatisfaction felt by some patients [8].…”

Introduction:Cataract surgery with intraocular multifocal lens (IOML) implant allows visual recovery for different distances, regardless of the use of external correction, despiteits undesirable effects. The visual function has impact on quality of life, as on the ability to perform daily activities and on the patient satisfaction. Objectives: Evaluate satisfaction and quality of vision in patients who underwent phacoemulsification surgery with implant of multifocal intraocular lens, even with the eyewear independence and with the presence of adverse effects.Methods: An observational, descriptive and retrospective study was carried out with patients undergoing phacoemulsification surgery with IOML implantation at a private clinic in Florianópolis (Brazil) from January 2009 to December 2015. Objective data were collected from electronic medical records and the questionnaire "TyPEqustionnaire" was completed for subjective analysis, through telephone calls. Afterwards, the data were submitted to descriptive statistical analysis and the corresponding variables were correlated through the Pearson chi-square test, with a significance level of p <0.05 being considered.Results: A total of 436 cataract surgeries were performed with IOML implantation in 223 patients. Ninety-nine patients were excluded either because they did not complete the inclusion criteria list or because of the impossibility of being reached by telephone contact. Thus, 124 patients effectively participated in the study. There was a higher prevalence of women (79%), and a non-toric aspheric lens implant (65%). The average age was 64 years and all patients were residents in the Santa Catarina state. The mean score for far distance vision was 8.35; for intermediate distance vision was 8.43 and for near distance vision was 7.87; at a rate from 0 to 10, being equivalent to unsatisfactory and very satisfied visual acuity, respectively. Glare was reported in 44,30% of patients, halos during the day were verified in 20,60% of the sample and halo-related complaint at night in 35,48% of the patients. Conclusion:In the final assessment of the questionnaire it was found that the patients were satisfied with the visual acuity after IOML implant. There was a moderate incidence of undesirable photopic effects and little dependence on glasses. IOML may be a good choice when immersed in real expectation for patients who want vision improvement without eyewear. In addition, the good relationship between surgeon and patient and the informed consent about the procedure are very important to the patient's satisfaction with the final visual result as well.

Halo and Through-Focus Performance of Four Diffractive Multifocal Intraocular Lenses

Abstract: Differences in the design of the diffractive IOLs translate into differences in optical quality at their foci, through-focus performance, and halo features, which can offer further information to surgeons when selecting which IOL to implant.
