Abstract
Purpose: :
To evaluate acuity and quality of vision after cataract surgery with implantation of bifocal optic intraocular lens ACRITEC Acri.Lisa 356D.
Methods: :
14 eyes (10 patients) underwent phacoemulsification and Acri.Lisa 356D IOL implantation with a follow-up of 6 months. The postoperative main visual outcome evaluations were: uncorrected (UCDVA) and best corrected (BCDVA) distance visual acuity (Snellen), uncorrected (UNVA) and best distance-corrected (BDCNVA) near visual acuity (De Wecker) and mean addition to reach De Wecker (DW) 1 on the reading chart. Contrast sensitivity study (CSV-1000 HGV instrument, Vector Vision Inc.) was also conducted.
Results: :
In our study we found the following mean values: UCDVA 7,38±2,93, BCDVA 10,00±0,00; UNVA 0,98±0.44 DW, BDCNVA 0,98±0.44 DW. Mean refractive error spherical equivalent (SE) was -0,40±0,45 D. Mean contrast sensitivity under standard instrument light level of 85 cd/mm was 5,00±1,63 at 3 cpd, 4,00±2.16 at 6 cpd, 3,75±0,96 at 12 cpd and 4,25±2,06 at 18 cpd. Mean contrast sensitivity under glare condition was 5,62±1,33 at 3 cpd, 4,15±1,46 at 6 cpd, 3,46±1,85 at 12 cpd, 2,85±1,82 at 18 cpd.
Conclusions: :
Implantation of ACRITEC Acri.Lisa 356D bifocal optic IOL provides very satisfactory far and near vision restoration. Contrast sensitivity with and without glare seems to remain on normal ranges of standard monofocal pseudophakic eye.
