Abstract Details

Purpose:

To evaluate the safety and efficiency of presbyopia correction with a bifocal intracorneal implant in the non-dominant eye of emmetropic patients.

Setting:

Prospective, controlled, clinical trial

Methods:

Eighteen emmetropic patients with presbyopia were treated with a bifocal intracorneal implant (Flexivue Microlens) by a single surgeon. The implant was implanted in the non dominant eye (study eye). Main outcome measures were uncorrected and corrected near and distance visual acuity (UNVA, DCNVA, UDVA, BSCVA), spherical equivalent (SE) and subjective quality of vision (QoV).

Results:

At one week and one, three, and six months postoperative the study eyes had a significantly better UNVA than preoperative und compared to the control group (0.21±0.2, 0.17±0.13, 0.16±0.11, 0.16±0.09 vs 0.47±0.15, 0.47±0.17, 0.46±0.09, 0.39±0.2; p<0.001), but statistically significantly worse UDVA (0.32±0.15, 0.22±0.15, 0.19±0.14, 0.24±0.17 vs -0.08±0.08, -0.09±0.13, -0.1±0.08, -0.11±0.11; p<0.001). The QoV also showed a reduced visual quality regarding distance vision in favor of near visual quality in the study eyes.

Conclusions:

The Flexivue implant offers significant improvement of UNVA in expense of monocular UDVA and contrast vision. Nevertheless, most patients report a mostly spectacle free everyday life because of unchanged binocular UDVA.
