Abstract
The AT LISA 809 (Carl Zeiss Meditec AG) is an aspheric bifocal biconvex diffractive IOL with near vision add of +3.75 D over the distance power.
Forty-eight eyes of 24 bilateral cataract patients with age ranging between 47 and 77 years were implanted with AT LISA 809 IOL. Distance and near visual acuities, contrast sensitivity, defocus curve and ocular optical performance, quality of vision and patient satisfaction were reported.
At 6 months after surgery, a statistical significant improvement was observed in the uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA) and distance corrected near visual acuity (DCNVA) (p < 0.01). The profile of the defocus curve shows 2 peaks of maximum vision for defocus levels of 0.00 D and −2.50 D. Postoperative intraocular optical quality showed no significant amounts of these aberrometer parameters. In this study, it was found that halos are the most prominent visual symptom, and the spectacle independence was 82.1%.
The AT LISA 809 IOL multifocal IOL provides a good visual rehabilitation after cataract surgery.
