Abstract Details

Purpose:

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.

Setting:

C.M.A. Centro Microchirurgia Ambulatoriale Monza – Italy.

Methods:

Only eyes with regular were included in this study: 27 eyes of 16 patients mean age: 54.44 ± 7.33 years. Preop SE was -1,16 ± 3,61 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.

Results:

At three years BCDVA was 20/20,91 ± 3,02. SE was -0,27 ±  0,49. Residual astigmatism was -0,02 ± 0,24. UCNV 20/22 96.7% of eyes achieved postop refractive results within ± 0.50 diopter.

Conclusions:

Trifocal Lenses provided good  visual performances also  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.
