Abstract Details

Purpose:

The aim of the paper is to evaluate the tolerance of the patients to the residual corneal astigmatism following cataract surgery with the implantation of the Acrysof IQ PanOptix IOL. The distance, intermediate and near visual acuity is compared to the laser enhancement rate. This may help in the decision making process when a toric or a non toric implant must be chosen.

Setting:

Eye clinic Zlin, Zlin, Czech Republic

Methods:

Non-randomized study of 400 consecutive cases of the implantation of the non toric Acrysof IQ PanOptix IOL. Implanted diopters +13 to +34D. 18% of eyes with +20 and lower D, 69% od the 20,5 to 25D, 13% 25,5 and higher D. Results were subdivided into subgroups based on the residual astigmatism in 0,25D steps. Eyes without pathology, only 2 lines of visual loss due to amblyopia, no complications. Visual acuity for the near, intermediate and distance evaluated at 6 weeks, laser enhancement rate due to low satisfaction with the quality of vision evaluated at 6 months following the surgery.

Results:

Similar VA results at 6 weeks among groups. UCDVA 0,91 in the 0-0,25 Dcyl group, 0,84 in the 1,25 Dcyl group, UCIVA 0,84 in the 0-0,25 Dcyl group, 0,8 on the 1,25 Dcyl group, UCNVA J.1,7 in the 0-0,25 Dcyl, 1,8 in the 1,25 Dcyl group. Laser enhancement rate at six months: 0% at 0-0,25 Dcyl group, 3% at 0,5 Dcyl group (intolerance to myopia in a hyperopic patient), 7% in 0,75 Dcyl group, 17% in higher cylinder groups.

Conclusions:

Patients with trifocal lens require a good quality of vision on all distances. A corneal astigmatism may be the factor of the lower satisfaction with the surgery. Despite good visual functions in all groups, patients with astigmatism of 1D and higher were more likely to require a laser enhancement. We strongly suggest, that patients with the prediction of the higher postoperative corneal astigmatism should be informed that a more complex solution of their refractive error may be needed peri- or postoperatively.
