Abstract
Purpose: :
To report the safety, efficacy and predictability of presbyopic LASIK treatments in myopic and hyperopic eyes. Excimer laser correction can represents an attractive option creating a multifocal cornea.
Methods: :
46 eyes of 10 hyperopic patients ( SE + 1,85 ± 1,3 D) and 13 myopic patients (SE - 4,95± 1,86 D) treated with LASIK using Bausch&LombXP microkeratome and Mel 80 Zeiss excimer laser for the correction of presbyopia. Mean patient age was 54 years (range 47- 68). Mean spectacle near addition was 1,89±0,48 D). Main outcome measures were: UCVA and BCVA for near and distance; spherical equivalent refraction; corneal aberrations focusing on spherical aberration.
Results: :
Six months results will be presented. Mean postoperative myopic spherical equivalent refraction was -0.40 ± 0.43 D; mean postoperative hyperopic spherical equivalent refraction was 0.35 ± 0.39. Binocular UCVA was 20/30 or better for all the patients, no patients reported using spectacles full time for near or distance. Aberrations analysis showed a decrease in total abberrations RMS and a slight increase of coma and high order aberrations RMS. We got a significant change of spherical aberration.
