[The "Array" silicone multi-focal lens: experiences after 150 implantations].

BACKGROUND: The Array-MIOL offers the advantage of an increased depth of focus; the aim of our study was to compare other functional results with those of a monofocal IOL.

METHODS: Uncorrected and corrected distance and near visual acuity were measured in the early postoperative period and after 3 months. Results of contrast acuity (Regan charts) and contrast sensitivity (BVAT II-SG video acuity tester) of the Array-MIOL and a monofocal IOL were compared at the 3-months follow-up.

RESULTS: Distance visual acuity of the multifocal group did not differ from the monofocal results; uncorrected and distance corrected near acuity were significantly superior in Array patients. The monofocal IOL showed a superior contrast acuity only at the 11% level and a superior contrast sensitivity only at one spatial frequency (20 cpd). Bilateral implantation of the Array-MIOL seems to further improve functional results.

CONCLUSION: Implantation of the Array silicone multifocal IOL offers the advantage of pseudoaccommodation without relevant impairment of other visual functions.
