“…However, at 6 cpd, the MCS in the Tecnis ZCB00 was significantly better than that in the Sensar AR40e. Our results were comparable to those from the study by Denoyer et al17 who compared aspheric Tecnis Z9000 and spherical CeeOn™ Edge 911 (Pharmacia, Kalamazoo, MI) IOLs. That study revealed that the Tecnis Z9000 group showed significantly better MCS at high spatial frequencies; however, the contrast sensitivity under photopic and glare conditions did not differ between the two groups.…”

SynopsisThe aspheric, one-piece design of the Tecnis® ZCB00 intraocular lens provided higher mesopic contrast sensitivity and relatively constant refraction at different pupil sizes compared to the Sensar® AR40e.PurposeComparing the impact on functional vision of the aspheric Tecnis® ZCB00 one-piece lens compared to the spherical Sensar® AR40e three-piece lens.SettingNational Eye Hospital, Cairo, Egypt.MethodsIn this prospective study, we implanted 32 Tecnis ZCB00 (Abbott Medical Optics, Santa Ana, CA) and 30 Sensar AR40e (Pharamacia and Upjohn LLC, North Peapack, NJ) lenses. Twenty-three patients in the ZCB00 group and 13 patients in the AR40e group provided reliable, reproducible data, and were therefore included in the statistical analysis. After 8 weeks, we measured photopic contrast sensitivity (PCS) at 85 cd/m2 and mesopic contrast sensitivity (MCS) at 5 cd/m2. Uncorrected and best-corrected visual acuity were measured. Myopic shift was analyzed by comparing the manifest refraction spherical equivalent at 3 days and 8 weeks after surgery in the normal and dilated pupil.ResultsThe Tecnis ZCB00 group showed significantly better MCS than the Sensar AR40e group at a spatial frequency of six cycles per degree (cpd) (P = 0.037), but not at 3, 12, or 18 cpd (P = 0.299, P = 0.226, and P = 0.396, respectively). There were no significant differences between groups in corrected distance visual acuity (P = 0.175) or PCS at 3, 6, 12, or 18 cpd spatial frequencies (P = 0.440, P = 0.176, P = 0.365, and P = 0.251, respectively). The ZCB00 group showed less myopic shift in normal and dilated pupils between 3 days and 8 weeks after surgery compared to the AR40e group, but this difference was not significant.ConclusionThe Tecnis one-piece ZCB00 provided higher MCS at moderate spatial frequency than the three-piece Sensar AR40e, and was associated with relatively constant refraction at different pupil sizes.

“…They have an aspheric, modified prolate anterior surface that is designed to minimize spherical aberrations and improve contrast sensitivity after cataract surgery [21]. In contrast, Tecnis® multifocal IOLs (ZMB00, ZMA00) are foldable three-piece (ZMB00) or one-piece (ZMA00) diffractive multifocal acrylic IOLs with 6.0-mm optics and an aspheric, modified prolate anterior surface.…”

PurposeTo compare the visual performance of multifocal intraocular lenses (IOLs) and monofocal IOLs made of the same material.MethodsThe subjects included patients implanted with either Tecnis® monofocal IOLs (ZA9003 or ZCB00) or Tecnis® multifocal IOLs (ZMA00 or ZMB00) bilaterally. We conducted a retrospective study comparing the two types of IOLs. The multifocal group included 46 patients who were implanted with Tecnis® multifocal IOLs bilaterally. The monofocal group was an age- and sex-matched control group, and included 85 patients who were implanted with Tecnis® monofocal IOLs bilaterally. Lens opacity grading, the radius of corneal curvature, corneal astigmatism, axial length and the refractive status were measured preoperatively. Pupil size, ocular aberrometry, distance, intermediate and near visual acuity, contrast sensitivity with and without glare and the responses to a quality-of-vision questionnaire were evaluated pre- and postoperatively.ResultsThe uncorrected near visual acuity was significantly better in the multifocal group, whereas both the corrected intermediate and near visual acuity were better in the monofocal group. Contrast sensitivity (with and without glare) was significantly better in the monofocal group. The rate of spectacle dependency was significantly lower in the multifocal group. There were no significant differences between the two groups regarding most items of the postoperative quality-of-vision questionnaire (VFQ-25), with the exception that the patients in the monofocal group reported fewer problems with nighttime driving.ConclusionsThe multifocal IOLs used in this study reduced spectacle dependency more so than monofocal IOLs and did not compromise the subjective visual function, with the exception of nighttime driving.

“…However, there has not been any statistical significance observed between the aspherical IOLs [2][3][4]. Our study is the first to compare two single-piece hydrophobic acrylic aspherical IOLs and demonstrate data on VEP, retinal sensitivity, and fixation stability.…”

In this study, we investigated the visual performance of two aspherical intraocular lenses (IOLs), Tecnis ZCB00 and Acrysof SN60WF, by measuring high-order aberration, visual evoked potentials (VEP), retinal sensitivity, and fixation stability by MP-1 microperimetry and contrast sensitivity values. Twenty-two patients with age-related cataract were randomly allocated to either the Tecnis or the Acrysof group. All measurements were taken from patients of both groups 2 months postoperatively. Statistical analysis was performed with Student's t test, where P-values < 0.05 were considered significant. Results were not statistically significant with regard to high-order aberration, VEP, retinal sensitivity, and fixation stability. However, the contrast sensitivity values varied significantly between Tecnis ZCB00 and Acrysof SN60WF, with Tecnis ZCB00 performing better. The anterior aspherical surface design of the Tecnis IOL indicated better mesopic contrast sensitivity at mediate and high frequencies, ensuring a better quality of vision after cataract surgery.

Quality of vision after cataract surgery after Tecnis Z9000 intraocular lens implantation

Abstract: Implantation of an aspherical IOL with a negative spherical aberration resulted in reduced ocular spherical aberration and improved mesopic contrast sensitivity and led to better subjective quality of vision.
