Objective: To study the results of using AcrySof ReStor multifocal intraocular lens (MIOL) after the cataract operation.
Methods: It was a non-random comparative clinical study. After the small incision phacoemulsification, AcrySof ReStor MIOL was inserted into the eye in 22 cases (30 eyes, observed group); single focal intraocular lens (SIOL) was inserted in 20 cases (30 eyes, control group). Visual acuity, corneal astigmatism, operative complications, spectacles independence, patient satisfaction and untoward visual symptoms were observed. The follow up period was 3-14 months.
Results: Patients with uncorrected near visual acuity 0.5 or better accounted for 86.7% (26/30) in the observed group and 33.3% (10/30) in the control group, respectively. There was a significantly statistical difference between these two groups 3 months postoperatively ( X2 = 17.78, P < 0.05). Patients with uncorrected near visual acuity 1.0 or better accounted for 66.7 % (20/30) in the observed group and 0% (0/30) in the control group. There was a significantly statistical difference between these two groups 3 months postoperatively (X2 = 21.82, P < 0.05). There was no statistically significant difference in the corrected near and distant visual acuities and uncorrected distant visual acuity between these two groups (X2 = 0.13, 0.35, 0.35; P > 0.05). There was no statistically significant difference in preoperative corneal astigmatism and corneal astigmatism 1 week, 1 month and 3 months after the operation between these two groups (t = -0.46, -0.47, -0.44, -0.48; P > 0.05). Spectacles were not necessary in 86.7% (26/30) and 13.3% (4/30) cases in observed and control groups, respectively. In the observed group, glucocorticoid-induced high ocular pressure occurred in two eyes. One eye required Nd: YAG laser posterior capsulotomy in the control group.
Conclusions: AcrySof ReStor MIOL implantation provides a better distant and near vision, spectacles are not required in 86.7% cases and the life quality is improved.

Purpose: This study assessed the incidence of postsurgical intraocular inflammation after cataract extraction by phacoemulsification and implantation with AcrySof IQ ReSTOR intraocular lenses (IOLs) produced using an updated manufacturing process. Incidence rates were compared with historical rates of postsurgical intraocular inflammation.
Methods: This was a prospective, multicenter, post-approval study at 34 sites.

Most previous studies on the effects of multifocal intraocular lenses (MIOL) on Humphrey visual field (HVF) used presbyopic corrective lens (PC). There has been insufficient data from patients with MIOL performing HVF with and without PC. This study aimed to determine the effect of PC on HVF testing in patients with MIOL.

Evaluating chromatic aberration for a multifocal intraocular lens (MIOL) in vitro is essential for studying its performance because it helps determine the most appropriate lens for each patient, enhancing surgical outcomes. While refractive MIOLs with angular power variation have shown positive clinical outcomes, studies of these MIOLs on optical benches primarily employed monochromatic green light, neglecting the impact of longitudinal chromatic aberration (LCA) on MIOL performance. To address this gap, we evaluated the through-focus modulation transfer function (TF-MTF) and the point spread function (PSF) of two refractive segmented extended depth of focus intraocular lenses (IOLs) (Femtis Comfort and Precizon Presbyopic), comparing the results with those obtained with two widely known diffractive multifocal intraocular lenses (AcrySof IQ ReSTOR and FineVision Pod F).

Purpose: To evaluate and compare the long-term results after bilateral implantation of different multifocal intraocular lenses (MIOLs).
Methods: This retrospective comparative study included 42 patients who underwent cataract surgery with bilateral MIOL implantation. Patients were divided into 5 groups: Group 1 received a refractive ReZoom NGX1 IOL (AMO), Group 2 a diffractive Acrysof ReSTOR SA60D3 IOL (Alcon), and Group 3 a diffractive Tecnis ZM900 IOL (AMO).
