Abstract Details


To evaluate uncorrected (UCVA) and best-corrected visual acuity at different distances and lighting conditions as well as depth of field of an aspheric diffractive acrylic MIOL, Tecnis 1-piece ZMB00.


5 study sites across Europe: Aston University, Birmingham, UK; Augen-Zentrum-Nordwest, Ahaus, Germany; Hospital Universitario Quirón, Madrid, Spain; Goes Eye Center, Antwerp, Belgium; Midland Eye, Solihull, UK.


Fifty-two patients with cataracts (average age 68.5 ±10.5 years, 35 female) were bilaterally implanted with the aspheric diffractive Tecnis 1-piece ZMB00 multifocal intraocular lens (MIOL). Four to six months after surgery uncorrected and best-corrected distance and near visual acuity, under photopic and mesopic lighting were measured, the defocus curves were tested and photic phenomena were documented.


The residual refractive error was 0.01ḟ0.47D with 56% of eyes within ḟ0.25D and 97% within ḟ1.0D. Uncorrected visual acuity was 0.15ḟ0.30logMAR at distance and 0.15ḟ0.33 logMAR at near, only reducing to 0.21ḟ0.25logMAR at distance and 0.18ḟ0.26logMAR at near in mesopic conditions. The defocus curve showed a near addition between 2.5-3.0D. Spectacle independence was 100% for distance and 88% for near. Four patients reported glare at night and 2 noted glare symptoms during the day. No starburst sensations were reported.


The Tecnis 1-Piece ZMB00 MIOL provides a good visual outcome at distance and near under photopic and mesopic conditions with minimal adverse effects. The defocus curves showed good functional vision at a comfortable reading distance.
