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?

Day ophthalmic clinic

One arm of the study consisted of them Oculentis Mplus X IOL made of a hydrophilic copolymer with 25% water content and a hydrophobic surface. It has a, UV filter and a refractive index of 1.,46.

The other IOL was the Teleon AcunexVariomax. This is made of a hydrophobic material designed to be, glistening-free. The refractive index is 1.54 with a water content of 4%. As well as the UV filter there is one for blue light.

40 eyes of 20 patients were implanted bilaterally in each arm. The results were compared in a retrospective case study from September 2018 -January 2021  

Both 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 like glare,  and halos were evaluated. The patients’ satisfaction with their IOLs 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 , The questionnaire showed ,that 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.
