A Comparison Between Two Multifocal I0ls With Asymmetric Optics Made From Different Materials

To establish whether the different materials of these IOLs influence the  optical and functional result after their implantation?

Augenklinik Cham,Germany

Mplus X IOL (Oculentis)made of a hydrophilic copolymer with 25% water content and a hydrophobic surface. UV filter and a refractive index of 1.,46.AcunexVariomax(Teleon).made of a hydrophobic material designed to be, glistening-free. The refractive index is 1.54 with a water content of 4%. UV filter there is one for blue light.40 eyes of 20 patients were implanted bilaterally in both groups. The results were compared in a retrospective case study from September 2018 -January 2021 ,Uncorrected (UCVA) and best corrected (BCVA) distance, intermediate and near vision were measured as well as, post-op refraction  The quality of vision, and dysphotopsias  were evaluated. The patients’ satisfaction  was assessed using a validated questionnaire.

Three months after the Implantation of Mplus X the mean UCVA for distance was 0,78,; for intermediate 0,72;for near 0.86. BCVA  was 0,83 ; The mean refraction was +0,3D .

For the second group the X the mean UCVA for distance was 0,8,; for intermediate 0,70;for near 0.79. BCVA  was 0,85  ; The mean refraction was +0,25 D .None of the patients needed  glasses for working on PC ,  independence of glasses is after Mplus X higher.

The patients implanted with asymmetric multifocal hydrophobic IOLs AcunexVariomax achieved comparable visual acuity for distance and intermediate, less dysphotopsia .The visual acuity for near was better for MplusX as well the independence of the glasses

We  assume ,that the material of  IOL  can influence the optical but also the functional result.
