Analysis of Corneal Topography and Wavefront Aberrations after Upper Eyelid Blepharoplasty

In this prospective, interventional study, the effect of upper eyelid blepharoplasty (UEB) surgery performed on dermatochalasis patients on the cornea was investigated by corneal topography, and its effect on visual function was investigated by examining visual acuity and corneal wavefront aberrations. Eighty eyelids of 40 patients were evaluated at least 1 month after surgery. No significant differences were found for visual acuity, flat keratometry, steep keratometry, average keratometry, topographic astigmatism, axis, central corneal thickness, and anterior chamber depth (p>0.05 for all). While preoperative anterior chamber volume (ACV) was 122.06±28.0 mm3, the postoperative ACV was 126.23±28.80 mm3 (p=0.045). Root mean square-higher-order aberrations for total corneal surface (RMS-HOAs) in a 6-mm optical zone decreased significantly from 0.331±0.115 μm to 0.255±0.106 μm (p
