Factors For Visual Outcomes Of A New Monofocal Iol With Enhanced Intermediate Function

To investigate the Effect of decentration on the visual performance of far, intermediate and near in patients with implantation of enhanced monofocal intraocular lens (IOL)

Thirty cataract patients who underwent uneventful enhanced monofocal IOL (Tecnis® Eyhance ICB00) implantation were enrolled. 

Before surgery, the following data were recorded: sex, age, axial length, white to white, angle kappa, angle alpha, and corrected distance visual acuity. At 1 month after surgery, a postoperative visual acuity evaluation included the measurement of distance visual acuity, near visual acuity, and intermediate visual acuity. OPD-Scan III aberrometer was used to collect the decentration data.

There was a negative trend between IOL decentration and postoperative intermediate visual acuity(Pearson correlation analysis, r = -0.325, P = 0.475). Also there was a negative trend between IOL decentration and postoperative near visual acuity (Pearson correlation analysis, r = -0.452, P = 0.308), while no correlations were found between IOL decentration and postoperative distance visual acuity(Pearson correlation analysis, r = -0.003, P = 0.992).

In enhanced monofocal IOLs, decentration did not affect overall visual performance, but tended to have a more negative effect on near and intermediate visual acuity.
