Visual acuity and macular sensitivity in myopic eyes before and after laser in situ keratomileusis

To evaluate the changes in visual acuity (VA) and in macular sensitivity in myopic eyes subjected to laser in situ keratomileusis (LASIK) refractive surgery. In 38 myopic eyes, VA by Snellen's table and macular sensitivity by scanning laser ophthalmoscope (SLO) microperimetry were assessed befo...

Description
Summary:To evaluate the changes in visual acuity (VA) and in macular sensitivity in myopic eyes subjected to laser in situ keratomileusis (LASIK) refractive surgery. In 38 myopic eyes, VA by Snellen's table and macular sensitivity by scanning laser ophthalmoscope (SLO) microperimetry were assessed before and after 24 weeks after LASIK surgery. The myopic eyes were divided into three age-matched groups: Group A = from -5 diopters (D) to -7 D and normal SLO-macular sensitivity (15 eyes); Group B = from -8 D to -16 D and normal SLO-macular sensitivity (9 eyes); and Group C = from -8 D to -16 D and abnormal SLO-macular sensitivity. Group A and B eyes, at the first week after LASIK surgery, we observed a significant analysis of variance, p0.01) were found when compared to baseline. In Group C patients, at 1 and 4 weeks after surgical treatment, we observed a significant (p0.01), while values of SLO-macular sensitivity were still significantly (p
