Purpose:
To evaluate the improvement of CVA in patients with an unexplained lack of CVA (aberropia) demanding perfect vision for their work, after treatment by Wavefront guided (WFG) LASIK.
Setting:
Roayah Eye Centers, Assiut, Egypt
Methods:
Prospective clinical study on 8 consecutive aberropic patients (14 eyes) with compound myopic astigmatism suffering from imperfect CVA (0.6 to 0.9 decimal acuity) were treated by WFG LASIK. Objective evaluation of the High-Order Aberrations (HOAs) using Hartmann-Shack aberrometer and subjective evaluation of the visual acuity and contrast sensitivity were done. Data was recorded for 1 year of follow-up.
Results:
All the patients gained higher postoperative UVA over the preoperative CVA (? 0.2 decimal acuity) with high degree of efficiency, stability for 1 year and satisfaction for professional work. Statistically significant difference between the postoperative total HOAs RMS mean (0.28 ± 0.18 ?m) and the preoperative total HOAs RMS mean (0.47 ± 0.22 ?m) was found (P<0.05, non parametric test). Highly significant improvement (P<0.001, non parametric test) of the postoperative UVA mean (-0.06 ± 0.03 LogMAR) in comparison to the preoperative CVA mean (0.10 ± 0.05 LogMAR) was achieved.
Conclusions:
WFG LASIK is no more an elective refractive surgery for aberropic patients and should be considered as a therapeutic procedure for gaining higher VA with high visual quality, especially for professionals demanding perfect vision like drivers, engineers and many others. FINANCIAL DISCLOSURE?: No
