“…13 Montés-Micó and coauthors 13 reported that patients with multifocal IOLs had worse CSF under dim conditions. Studies evaluating the CSF after hybrid multifocal IOL implants 20,26,29,30,32,35,38,39,43,[46][47][48][49][50] also found a reduction in contrast sensitivity when the luminance level was reduced, particularly for higher spatial frequencies. This trend agrees with classic data on the effect of the luminance level on contrast sensitivity.…”

“…All studies 20 30,36,38,40 show that the new AcrySof ReSTOR aspheric IOL with a +3.00 D addition provides better intermediate visual performance than AcrySof ReSTOR aspheric IOL with +4.00 D addition, with no decrease for either distance or near visual acuities. It seems that the lower addition of the IOL plays an important role in the improvement of visual acuity for intermediate distances.…”

“…Many studies [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] have evaluated distance and near visual acuity after hybrid multifocal IOL implantation (Tables 1 and 2). In most of these studies, average monocular distance visual acuity (VA) and corrected for distance near vision (NV) after multifocal IOL implantation were better than 0.1 logMAR (about 6/7.5), with most eyes maintaining or improving both VA and distance corrected near vision.…”

It has been suggested that CSF under photopic and mesopic conditions, after multifocal IOL implantation, must be lower than that obtained after monofocal IOL implantation, but still within the normal range.…”

During the past years, the wish to become independent of spectacles has been growing among cataract and presbyopic patients due to many factors, such as the increase in near visual demands, the aesthetic need for a spectacle-free image and ageing of refractive surgery patients, among others. This review assesses recently published studies that analyse visual and optical performance through different metrics of eyes implanted with multifocal intraocular lenses (IOLs), particularly hybrid IOL designs. The published evidence suggests that hybrid multifocal IOLs provide very good outcomes in a number of visual and optical performance parameters. Patients implanted with this type of IOL obtain a satisfactory full range of visual functions, including patients of particular characteristics such as highly ametropic or post-LASIK.

“…Bifocal refractive (1)(2)(3) , diffractive (4)(5)(6)(7) , spherical hybrid (8)(9)(10)(11) and aspheric hybrid (12)(13)(14)(15)(16) IOLs generate two focal points along the optical axis to provide good monocular uncorrected distance and near visual acuity (UCVA and UNVA, respectively) as well as functional intermediate vision. The bifocal IOLs have also been implanted in RLE with good results at distance and near vision (17)(18)(19)(20)(21)(22)(23)(24)(25) .…”

Purpose: To evaluate distance and near contrast sensitivity (CS) under photopic and mesopic conditions before and after refractive lens exchange (RLE) and implantation of the aspheric AcrySof ® ReSTOR ® (SN6AD3 model) intraocular lens (IOL). Methods: Seventy-four eyes of 37 patients after RLE underwent bilateral implantation with the aspheric AcrySof ReSTOR IOL. The patient sample was divided into myopic and hyperopic groups. Monocular uncorrected visual acuity at distance and near (UCVA and UCNVA, respectively) and monocular best corrected visual acuity at distance and near (BCVA and BCNVA, respectively) were measured before and 6 months postoperatively. Monocular CS function was measured at three different luminance levels (85, 5 and 2.5 cd/m 2 ) before and after RLE. Post-implantation results at 6 months were compared with those found before surgery. Results: Our results revealed that patients in both groups obtained good UCVA and BCVA after RLE at distance and near vision in relation to pre-surgery values. No statistically significant differences were found between the values of CS pre and post-RLE at distance and near, at any lighting condition and spatial frequency (p>0.002). Conclusions: Refractive lens exchange with aspheric AcrySof ReSTOR IOL in myo pic and hyperopic population provided good visual function and yield good distance and near CS under photopic and mesopic conditions.
