Abstract Details


To evaluate visual performance and patient satisfaction after implantation of an aspheric single piece multifocal lens with full diffractive pattern.


Private eye clinics in Ahaus (Germany), Antwerp (Belgium), and Madrid (Spain) and Midland Eye Institute/Aston University in Birmingham (UK)


Thirty-seven patients underwent bilateral cataract surgery and implantation of Tecnis ZMB00. Patients were followed-up after 1 day and 3 months. Major endpoints were uncorrected and best-corrected distance and near vision under photopic and mesopic conditions, as well as defocus curves and reading speed and acuity. Patients filled in a vision satisfaction questionnaire before and 3 months after surgery.


The patients achieved a mean uncorrected distance vision (decimal notation) of 1.02 ± 0.19 under photopic and 0.89 ± 0.16 under mesopic conditions, best-corrected vision was 1.16 ± 0.21 (photopic) and 1.04 ± 0.17 (mesopic). Uncorrected near vision (decimal notation) was 0.99±0.16 (photopic) and 0.80 ± 0.18 (mesopic). If near vision was corrected for distance, results were not significantly different to the uncorrected vision. Defocus curves showed a wide range of clear vision and patients achieved fluent reading speeds. Post-operative day and night glare were not different to the pre-operative situation. After surgery, none of the patients used spectacles for distance, and only 2 needed glasses for near tasks. Pre-operatively, only 6% of the patients found it easy to drive at night, whereas 76% regarded it as easy after surgery.


Tecnis ZMB00 provides excellent near and distance vision under mesopic and photopic conditions. The patient questionnaire revealed a significant improvement of satisfaction with vision at all distances and light conditions after surgery. FINANCIAL DISCLOSURE?: No
