Evaluation of visual performance and spectacle independence in patients that underwent cataract surgery with implantation of a segment multifocal intraocular lens (sMIOL) with a +8 D near addition suffering from chronic maculopathy.

Surgery was performed in patients with a manifest cataract and an expected visual acuity between 0.05 and 0.4 [decimal]. For implantation a hydrophilic, one piece sMIOL with a near addition of +8 D was chosen to create a magnification effect of around 1.5x to 2.0x in ultra near distance (aprox. 12cm) Postsurgical evaluation contained, UDVA, CDVA, UNVA, CNVA (ETDRS charts) and Salzburg Reading Desk (SRD) examinations. Near visual acuity was also tested in the subjective, best possible reading distance. To rule out possible complications with other magnification tools, those were evaluated, too.
UDVA increased from 1/25 MV to 0.10 with a CDVA of 0.16. UNVA was best possible in 13cm distance with 0.16. In the SRD examinations a UNVA of 0.14 in around 10cm could be found with an actual word count of 43 words/minute. No interference with other magnification tools were found.
First data of this new sMIOL model shows promising results in the treatment of cataract patients with chronic maculopathy. The subjective patient satisfaction is very high as the lens provides a good magnification effect to read print in daily routine without the use of other, sometimes non portable magnification tools. Still further research with more patients is needed.
