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