Abstract Details


To evaluate reading speed, spectacle independence and patient satisfaction of the Tecnis 1-piece ZMB00 aspheric diffractive intraocular lens (IOL)


5 study sites across Europe (Augen-Zentrum-Nordwest, Ahaus (GER), Life and Health Sciences, Aston University, Birmingham (UK), Hospital Universitario Quirón, Madrid (SP), Goes Eye Center, Antwerp (Belgium), Midland Eye Institute, Solihull (UK)


In this multinational multicentered prospective study, 52 cataract patients underwent bilateral implantation with the hydrophobic acrylic aspheric diffractive multifocal IOL after completing a questionnaire regarding their optical visual symptoms, use of visual correction and their visual satisfaction. The questionnaire was completed again 4-6 months after surgery along with measures of reading ability and spectacle independence.


The average reading speed was 121.4±30.8 words-per-minute. Words in text form could be read as small as -0.04 ± 0.18 logMAR. Spectacle independence was 100% for distance and 88% for near, with high levels of satisfaction reported. Overall rating of vision without glasses was 8.5 ± 1.1 out of 10 after surgery, compared to 4.7 ± 2.1 before surgery. This rating of vision without glasses (r=0.760) could be explained by pre-operative best-corrected distance acuity, post-operative reading acuity and post-operative uncorrected distance acuity in photopic conditions (p<0.001).


In conclusion, the diffractive multifocal acrylic Tecnis® 1-Piece ZMB00 IOL gave a high level of spectacle independence, a good reading acuity and speed along with a wide near vision range, resulting in high levels of patient satisfaction.
