Trifocal Iols Implantation In Cataract Patients That Have Experienced Previous Laser Vision Correction : Seven Years Follow Up

To evaluate visual performances of trifocal IOLs AT LISA tri 839 MP and AT LISA tri toric 939MP trifocal IOLs (Carl Zeiss Meditec AG - Jena - Germany) in patient that experienced previous laser vision correction

Piovella Global Center for Ophthalmology

Only eyes with regular cornea were included in this study: 36 eyes of 21 patients mean age:

56.57 ± 8.76 years. Preop SE was -0.91 ± 3,31 BCDVA 20/21.40 ± 3,18. Postop were measured: distance (5m) near (40cm) and intermediate (80 cm) VA, corneal topography and aberrometry, contrast sensitivity and defocus curve and quality of vision.Follow-up examinations were performed at day 1 2 7 30 90 180 360 and yearly

At six months BCDVA was 20/20,65 ± 2,51. SE was -0,20 ± 0,45.Residual astigmatism was 0,02 ± 0,42.83% of eyes after trifocal IOLs implantation achieved postop refractive results within ± 0.75 diopters

Trifocal IOLs provided good visual performances also with patients that experienced laser vision correction decades ago. To be selected for surgery eyes biometry needed to be applied with no difficulties and have to demonstrate no significant differences related the perfect IOLs power also after multiple attempts
