“…They reported a difference of approximately three letters in favor of the Tecnis Z9000 IOL implants. On the other hand, Thiagarajan et al14 found a statistically significant difference in CDVA but not clinically important (relative difference 1.5%), between Akreos Adapt Advanced Optics (AO) (Bausch and Lomb, Inc, Rochester, NY) aspheric intraocular lens (IOL) and the Sensar AR40e spherical acrylic IOL, in favor of the spherical IOL.…”

“…Munoz et al2 found that both the PCS and MCS were similar in patients that received implants of Tecnis Z9000, Sensar AR40e, or Stabibag IOLs. Also, Thiagarajan et al14 found no statistically significant differences in contrast sensitivity between Akreos Adapt Advanced Optics aspheric intraocular lens (IOL) and the Sensar AR40e spherical acrylic IOL.…”

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.

Purpose:Monofocal aspheric intraocular lenses (IOLs) provide better visual outcome compared to other available IOLs following cataract surgery. However, the imported IOLs are expensive and are not affordable by all subset of patients in low- to middle-income countries like India. The aim of this study is to compare the safety and efficacy of a relatively low cost indigenous IOL (Acriol EC) with an imported aspheric IOL (AcrySof IQ).Methods:A randomized controlled trial was conducted at a tertiary care centre. Two hundred and five eyes of 137 patients >45 years of age with uncomplicated age-related cataract were recruited. All cases underwent standard phacoemulsification and randomly assigned to one of the IOL implantations (Group I: AcrySof IOL; Group II: Acriol EC IOL). Primary outcome measure was best-corrected visual acuity (BCVA). Secondary outcomes included visual function (VF) score, spherical equivalent, contrast sensitivity, optical aberrations, and posterior capsular opacification. Independent t-test to compare two means; Mann–Whitney test; Pearson's Chi-square test, and McNemar's test were used for analyzing the nonparametric data such as incidence of posterior capsule opacification.Results:There was no significant difference in the mean postoperative BCVA at 1, 3, 6, and 12 months in either group (P > 0.05). The contrast sensitivity, wavefront aberrations, VF score, and posterior capsular opacification were comparable between the groups except for higher-order aberrations and spherical aberration, which were higher in Group II.Conclusions:Acriol EC IOL provides visual outcomes comparable to other commonly used aspheric IOLs with comparable safety and efficacy at an affordable cost.

“…Neben den verbesserten operativen Techniken haben die Patienten am meisten von den Vorteilen der Weiterentwicklung des Linsendesigns profitiert. Die Einführung von neuen Linsenmaterialien sowie der Wechsel von einem 3-stückigen zu einem 1-stückigen Haptikdesign ermöglichen nicht nur, die Intraokularlinsen durch eine Mikroinzision zu implantieren [1,2], sondern auch deren optische Qualität zu verbessern [3][4][5][6][7][8]. Außerdem kann derzeit die postoperative sphärische Aberration der Hornhaut durch die Implantation einer asphärischen Intraokularlinse (IOL) im Rahmen der Kataraktoperation optimiert werden [8][9][10][11][12].…”

“…Thiagarajan et al[6] hatten die Sehleistung nach Kataraktextraktion bei Implantation einer asphärischen mit einer sphärischen IOL verglichen und dabei keinen signifikanten Unterschied in der Entwicklung von Dysphotopsien oder in der Patientenzufriedenheit gefunden. Es sollte jedoch berücksichtigt werden, dass in dieser Studie ein anderes asphärisches IOL-Modell durch einen anderen subjektiven Fragebogen evaluiert wurde.…”
