Quantitative Evaluation of the Effects of Blepharoplasty on Visual Field, Corneal Changes, and Cosmetic Appearance.

Blepharoplasty is an important eyelid surgical procedure, involving aesthetic and functional changes to the eyelids. The aim of this study is to investigate the effects of upper eyelid blepharoplasty on changes in the visual field, corneal changes, and cosmetic appearance. This study was performed with preoperative and postoperative facial photographs of 32 patients who underwent bilateral blepharoplasty. Marginal reflex distance (MRD 1 ), percentage of corneal exposure area (CEA), and brow height (BH) were obtained from photographs. intraocular pressure (IOP) and ocular biometric parameters were also obtained. The morphometric and ocular parameters obtained from preoperative, postoperative first-month, and postoperative third-month patients were compared using repeated measures ANOVA test. Significant differences in MRD 1 , CEA, and BH were observed between preoperative, postoperative first-month, and postoperative third-month patients. Improvements were observed in left axis and right corneal astigmatism axis measurements in the postoperative third month compared with preoperative measurements, and the positive change was statistically significant ( P =0.020, P =0.036). Upper eyelid blepharoplasty could provide satisfactory functional and aesthetic outcomes by contributing to the improvement of pseudoptosis and reduction in eyebrow height postoperatively.
