Abstract Details


To evaluate visual outcomes and satisfaction in patients that had micro incisional cataract surgery (MICS) and the implantation of a varifocal (LENTIS Mplus) intraocular lens (IOL) with different addition in each eye at least 3 months after surgery


Vissum, Alicante Spain, Universidad Miguel Hernández.


Eighteen patients (36 eyes) that had MICS with the implantation of a varifocal IOL with a +3 addition in the non-dominant eye and a +1.5 addition in the dominant eye were evaluated at least three months after surgery. Binocular and monocular distance, near and intermediate vision, defocus curve, light distortion analysis, ocular aberrations and patients’ satisfaction were assessed. The RADNER reading charts were used to evaluate near vision at a 40cm distance, a pyramidal wavefront aberrometer was used for the ocular aberrations, and the NAVQ-10 questionnaire was used to evaluate patients’ satisfaction.


Mean binocular uncorrected distance vision (UDVA) was 0.91 (decimal), the corrected distance vision (CDVA) was 0.95. The binocular uncorrected near vision (UNVA) had a mean of 0.69; monocularly, the eyes with a +3.00 addition had a mean UNVA of 0.65 and 0.38 the eyes with the +1.50 addition. Mean binocular uncorrected and corrected intermediate vision was 0.42. Binocular defocus curve showed good visual outcomes at near and intermediate distances. The mean of the point of spread function (PSF) at a 4mm pupil was 0.1878 for the +3.00 addition eyes and 0.2093 for the +1.50 addition eyes.


The asymmetrical implantation of IOLs with different additions in order to reduce the visual side effects of magnification results in good visual outcomes at all distances as both lenses compensate each other limitations. One patient had neuroadaptation failure in which both IOLs had to be explanted; and one patient was completely dissatisfied with his visual outcome because he could not be completely spectacle independent, besides these two patients, all the other were satisfied with their visual outcomes.
