“…ese MIOLs were designed to provide functional far and near vision. e intermediate vision is acceptable but not as good as the far and near vision [1]. At present, there are 2 types of MIOLs in clinical practice: the traditional rotationally symmetric MIOL and rotationally asymmetric MIOL.…”

“…Modern cataract surgery with multifocal intraocular lens (MIOL) implantation provides high visual performance and achieves spectacle independence by two or more foci [1]. Many studies have evaluated the efficacy in most cases of MIOL implantation after cataract surgery, including diffractive [2][3][4], refractive [5][6][7], or a combination of both methods [8][9][10].…”

Purpose. To compare the short-term visual outcomes and intraocular optical performance of a rotationally asymmetric multifocal intraocular lens (MIOL) (SBL-3, Lenstec, Inc., Christ Church, Barbados) and an apodized diffractive MIOL (the Acrysof IQ ResTOR SN6AD1, Alcon Laboratories, Inc., Fort Worth, Texas, United States). Methods. A prospective, comparative, nonrandomized, and single-center study. Sixty-eight age-related cataract patients (81 eyes) after phacoemulsification cataract surgery and in-the-bag MIOL implantation were enrolled. Thirty-eight eyes received SBL-3, and 43 eyes received SN6AD1. Ophthalmological evaluation included uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), corrected distance visual acuity (CDVA), modulation transfer function (MTF), Strehl ratio (SR), intraocular aberrations (4 mm optical zone), and defocus curve at 3 months postoperatively. The Chinese version of the visual function index-14 (VF-12-CN) and spectacle independence were assessed in all patients. Results. There was no statistically significant difference between groups in postoperative UDVA (p=0.186). Postoperative UIVA and UNVA were significantly better for the SBL-3 group than for the SN6AD1 group (p<0.01). Statistically significant differences were revealed in defocus levels from –3.50 D to −4.00 D with better visual acuities for the SBL-3 group (p<0.01). For intraocular optical quality outcomes, statistically significant differences between groups were observed in RMS of intraocular total aberrations, coma, and trefoil high-order aberrations, presenting significantly higher values of these parameters in the eyes of the SBL-3 group (p < 0.01). Statistically significant differences were revealed in the MTF values at spatial frequencies of 5 and 10 cycles/degree between groups. There were no significant differences in scores of VF-12-CN, and spectacle independence between the groups (p>0.05). Conclusions. Both MIOLs were able to successfully restore visual function after cataract surgery. SBL-3 provided better UIVA and UNVA with a wider range of intermediate vision.

“…Because multifocal IOLs provide simultaneous vision, neuroadaption to coexisting retinal images is necessary to achieve optimal outcome (Alio et al. ). However, while impaired vision is associated with risk of falls (Lord ), we did not find evidence of a higher rate of falls in people with multifocal compared to monofocal IOLs.…”

Purpose: To investigate the impact of the type of the intraocular lenses (IOLs) in first-eye cataract surgery in elderly people on the risk of hospitalisation due to falls and injuries. Methods: A retrospective cohort study was conducted using the Australian Government Department Veterans' Affairs claims data. All people aged 65 years and above who had first cataract surgery between January 2007 and July 2017 were identified. Two cohorts were established depending on the type of IOLmonofocal and multifocal. The risk of injuries and falls requiring hospitalisation in the first 3 months post the surgery was assessed using Cox proportional hazard models with age at entry as primary time scale and adjusting for gender, comorbidities and prior history of falls. Results: There were 45 728 people across the two cohorts with the majority receiving monofocal lenses (97%), followed by multifocal lenses (3%) at the time of first cataract surgery. The risk of injury and falls was lower (but not significant) in the multifocal cohort compared to monofocal cohort (adjusted hazard ratio (aHR) 0.56, 95% CI 0.26-1.17). The risk was also lower (but not significant) when stratifying by age group at the time of the surgery. Conclusions: Regardless of age, multifocal lenses did not appear to be associated with the higher risk of serious injuries and falls after first-eye cataract surgery compared to monofocal lenses.

“…Understanding the patient's lifestyle requirements, visual goals, and personality traits are very important in determining candidacy for multifocal selection [6, 7]. Patients who are highly motivated for complete spectacle independence, able to accept a small compromise in distance vision, and convey a relaxed personality are often more successful with multifocal implantation [7].…”

Purpose: To report a case of a patient with unilateral Adie’s pupil who underwent bilateral cataract extraction with multifocal and monofocal posterior chamber intraocular lens (IOL) implantation. Methods: A 74-year-old woman presented to our institution complaining of worsening near vision. Gross examination revealed a 6-mm fixed pupil on the right eye (OD) and a 5-mm pupil reacting to 3 mm with light on the left eye (OS). Slit lamp examination revealed a tonic pupil with an exaggerated pupillary constriction to dilute pilocarpine OD. Dilated exam revealed 2–3+ nuclear and cortical lens changes bilaterally. The patient’s active lifestyle, personality, and biometry measurements made her a good candidate for multifocal IOL (MfIOL) implantation OS. Femtosecond laser-assisted cataract extraction with a ReSTOR +3 ADD (SN60D1) implantation was performed OS. Monofocal lens implantation (SN60WF) was performed OD 6 months later. Results: One year postoperatively, our patient had an uncorrected visual acuity (VAsc) of 20/15 for distance and J10 for near OD. Her VAsc was 20/25 +1 for distance and J1 for near OS. Visual acuity when using both eyes was 20/15 for distance and J1 for near. Conclusion: Optimizing success for MfIOL implantation is a multifactorial process. Large pupils preoperatively are of particular concern, as this may lead to increased dysphotopsia with pupil-dependent MfIOLs. Thus, patients with unilateral mydriasis, such as Aide’s pupil, may have a beneficial outcome combining multifocal-monofocal implantation after bilateral cataract extraction, especially if they are not a candidate for monovision but desire spectacle independence.
