Abstract

In a six-month follow-up, we aimed to determine the upper eyelid skin-only excision blepharoplasty technique on corneal biomechanics. Corneal anterior and posterior surface keratometry values (flat, steep, and mean keratometry, minimum radius of curvature), cylindrical power and axis, corneal volume, anterior chamber volume, and anterior chamber depth were compared. At the sixth month after surgery, the mean anterior cylindrical power, flat, steep, and mean keratometry values decreased significantly compared to preoperative values (p= 0.018, p=0.015, p=0.006, p=0.005, respectively). The mean corneal volume, anterior chamber volume, anterior chamber depth, and corneal posterior biomechanical parameters were not significantly affected. The upper eyelid skin-only excision blepharoplasty improved anterior corneal astigmatism and keratometry values.
