Purpose: : To examine changes in corneal aberrations after myopic or hyperopic LASIK in a presbyopic population treated or not for presbyopia.

Methods: : 90 eyes of 25 hyperopic patients ( SE + 2,05 ± 1,23 D) and 20 myopic patients (SE - 5,07± 1,75 D) treated with LASIK using Bausch&LombXP microkeratome and Mel 80 Zeiss excimer laser have beeen examined. Only 50 eyes underwent the correction of presbyopia. Mean patient age was 53 years (range 45- 68). Mean spectacle near addition was 1,68±0,57 D). Main outcome measures were: UCVA and BCVA for near and distance; spherical equivalent refraction; corneal aberrations focusing on spherical aberration.

Results: : One year results will be presented. Mean postoperative myopic spherical equivalent refraction was -0.43 ± 0.53 D; mean postoperative hyperopic spherical equivalent refraction was 0.56 ± 0.39. Binocular UCVA was 20/30 or better for all the patients, no patients reported using spectacles full time for distance. None of the patients treated for presbyopia reported full time dependence for near. Aberrations analysis showed a decrease in total abberrations RMS and an increase of coma and high order aberrations RMS. We got a significant change of spherical aberration and we report the results in eyes treated or not for presbyopia.

Conclusions: : . Presbyopic LASIK treatment can induce more corneal aberrations and may reduce the vision quality but it improves the near vision in presbyopic patients with myopia and hyperopia, reducing dependence on spectacles.
