Multifocal IOL's mix and match

Purpose: To evaluate patient satisfaction and visual performance on custom mixed multifocal IOL. Methods: From 01/2007 to 12/2007, 27 patients were implanted with one eye ReZoom®/Array (AMO) for near, intermediate and distance vision and one eye Tecnis®MF (AMO) for near and distance vision. The mean follow up period were 4 months. Patient satisfaction on custom mixed multifocal IOL was evaluated by means of visual performance and subjective questionnaire. Results: All of the patients had binocular uncorrected distance visual acuity of 20/25 or better. For near VA, 82% of patients could achieve J1at 30cm without the need for near glasses. For intermediate vision, 71% of patients could achieve J5 or better at 67cm. Only 5.6% of the patients required glasses for computer. None of them required glasses for near and distance. The mean satisfaction rate was 3.74 out of 5. In 10 patients with contrast sensitivity test done, the mean postoperative binocular best corrected contrast sensitivity (mesopic) for spatial frequency 3, 6, 12 and 18 cycles per degree were 5.9, 4.7, 3.8 and 3.8 respectively. There was a decrease in contrast sensitivity at high spatial frequency. The mean severity index for halo and night glare was 2.2 and 2.3 (out of 5) respectively. Conclusion: The overall performance of TecnisMF was better than ReZoom/Array at near (30cm) but ReZoom/Array performed better than TecnisMF at intermediate (67cm). Mixing and matching TecnisMF with ReZoom/Array gives satisfactory visual performance at all distances.
