Abstract Details


To evaluate the wisdom of performing wavefront-guided PRK in comparison with standard aspheric laser profile.


Republican ophthalmic center, Minsk, Belarus.


20 patients has undergone laser refractive treatment (PRK) bilaterally. In each case only one eye has undergone wavefront-guided ablation, standard aspheric protocol was used on the conjugated eye. Refraction, total HOA rate, pachymetry were measured before and 3 month after the operation, also questioning on the patients self-evaluation of vision quality (scale from 1 to 10) was performed 3 month post-op.


There was no significant difference in post operative refraction, total HOA rate and patient's self-evaluation of the both eyes vision quality. The increased pachymetry reduction was noticed in eyes that undergone wavefront-guided ablation in comparison with conjugate were standard aspheric protocol was used.


The results of the research lead us to the conclusion that there is no evident expediency of performing wavefront-guided PRK instead of using standard aspheric profile. Moreover, the increased tissue consumption during wavefront-guided ablation could be the additional risk factor for the corneal decompensation in case of ectasia development.
