Purpose:
|
To comparison the visual and refractive outcomes and aberrometric changes of aspheric-wave front-guided versus aspheric LASEK with TECHNOLAS TENEO 317-P excimer-Laser for myopia correction.
|
|
Methods:
|
Sixty-six eyes of 34 patients with myopia treated by TENEO 317-P excimer-Laser. 45 eyes treated with aspheric-wavefront-guided(AWG) and 21 eyes with aspheric LASEK(Aspheric group). Uncorrected and Distant corrected visual-acuity (UCVA & DCVA), aberrometric changes and complications were evaluated 1-week, 2 and 6-months post operation
|
|
Results:
|
The mean spherical equalent was -3.69±1.42 diopter(D) in AWG and -3.57±1.29 D in AG that improved to .06±.22 and .14±.25D 6 months post operation respectively. At 6 months LogMar UCVA and CDVA in both groups was 0.000 in all of patients. The higher order aberrations (HOAs) at 6mm pupil were .350μ in AWG and .270μ in AG that increased to .464μ and .431μ (30% versus 45%) respectively (P=0.00). Vertical coma and spherical aberration increased significantly (P=0.001). No eye lost lines of BSCVA at six months. The safety and efficacy index in both groups was 1 without any complications
|
|
Conclusion:
|
Both aspheric wave front-guided and aspheric ablation profile of TENEO 317P is safe and effective with a little change in HOAs in myopic patients treated with LASEK
