To evaluate visual performances of trifocal IOLs AT LISA tri 839 MP and AT LISA tri toric 939MP trifocal IOLs (Carl Zeiss Meditec) in patient that experienced previous laser vision correction exiting with regular cornea. To overcome the presbyopia weak points in patients who underwent refractive surgery decades ago.
Only eyes that experienced previous laser vision correction exiting with regular cornea were selected and included in this study: 16 eyes of 10 patients mean age: 55.81 ± 8.50 years. Preop SE was -0,53 ± 3,59 BCDVA 20/22 ± 3,56. Postop were measured: distance (5m) near (40cm) and intermediate (80 cm) VA, corneal topography and aberrometry, contrast sensitivity and defocus curve. Follow-up examinations were performed at day 1 2 7 30 90 180 360 720 To be included in the group biometry needed to detecting no significant outcome differences after multiple attempts.
At three years BCDVA was 20/20,91 ± 3,02. SE was -018 ± 0,45. Residual astigmatism was -0,02 ± 0,24. . UCNV 20/22 92% of eyes achieved after cataract surgery postop refractive results within ± 0.50 diopter
Trifocal Lenses provided good visual performances to correct presbyopia also in patients that experienced laser vision correction decades ago. To be included in the group biometry needed to detecting no significant outcome differences after multiple attempts. Only patient with regular cornea were considered.
