Abstract Details


To compare contralateral implantation of �.25D and �.0D add diffractive multifocal intraocular lenses (IOLs) with bilateral implantation of �.0D add diffractive multifocal IOL.


Department of Ophthalmology, Tokyo Dental College Suidobashi Hospital


The prospective study included 54 eyes of 27 patients who received multifocal IOLs bilaterally. In the first eye, a �.0D added diffractive multifocal IOL (ZMB00, AMO) was implanted. For the second eye, �.0D (MM group) or �.25D (ZLB00, AMO; ML group) added IOL was selected according with patient�â�€�™s preference of working distance. MM group included11 patients, and ML group included 16. Uncorrected and distance corrected binocular logMAR visual acuity (VA) for distance and intermediate-to-near (1m, and 50, 40 and 30cm), stereo vision, and contrast sensitivity were assessed 3 month or later postoperatively.


The mean uncorrected (distance corrected) binocular VAs of MM/ML groups were -0.100/-0.132(-0.170/-0.178) for distance, 0.028/0.022 (0.030/0.004) for 1m, 0.074/0.007 (0.057/-0.027) for 50cm, 0.089/0.021 (0.005/-0.016) for 40cm, and 0.068/0.065 (0.068/0.061) for 30cm; 50cm distance corrected binocular VA of the ML group was significantly better (P =0.015). The stereo vision of MM/ML group was 114.6/78.8 second with no significant difference. The contrast sensitivities of both groups were in the normal ranges at all spatial frequencies.


Contralateral implantation served benefits of two different additional power and would be effective for expanding the working distance.
