Purpose: : To examine clinical results and changes in corneal aberrations after myopic or hyperopic LASIK in a presbyopic population treated for presbyopia

Methods: : 54 eyes of 27 hyperopic patients ( SE + 2,24 ± 1,35 D) and 13 myopic patients (SE - 4,97± 1,65 D) treated with LASIK using Bausch&LombXP microkeratome and Mel 80 Zeiss excimer laser have beeen examined. All the eyes underwent the correction of presbyopia. Mean patient age was 54 years (range 44 - 68). Mean spectacle near addition was 1,76 ± 0,67 D). Main outcome measures were: UCVA and BCVA for near and distance; spherical equivalent refraction; corneal aberrations (spherical, coma ,high order aberration).

Results: : Two years results will be presented. Mean postoperative myopic spherical equivalent refraction was -0.48 ± 0.73 D; mean postoperative hyperopic spherical equivalent refraction was 0.65 ± 0.42. 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, a significative change of spherical aberrationsand an increase of coma and high order aberrations RMS.

Conclusions: : Presbyopic LASIK treatment induced corneal aberrations reducing in some cases the vision quality but improved functional near vision in hyperopic amd myopic presbiopic patients reducing dependence on spectacles.
