Abstract

Purpose: To evaluate the changes in dry eye parameters following cosmetic lower eyelid bleopharoplasty and combined upper-lower eyelid bleopharoplasty. Methods: A prospective study was conducted on 39 patients, including 20 who underwent lower eyelid bleopharoplasty (group 1) and 19 who underwent combined upper and lower eyelid bleopharoplasty (group 2). All procedures were performed by the same oculoplastic surgeon. Dry eye status was assessed preoperatively and at 1, 3 and 6 months postoperatively using the Ocular Surface Desiease Index (OSDI), Schirmer I test, tear film break up time (BUT), corneal fluorescein staining score, blink rate and incomplete blink ratio. Results: At 1 month, both groups showed a signifiacnt increase in OSDI scores, more pronounced in group 2 (p < 0,001). Schirmer I values remained stable in group 1 but decreased significantly in group 2 at all postoperative visits (p < 0,05). BUT decreased markedly at 1 month (p < 0,001) and gradually recoverd; at 6 months, group 1 reached baseline while group 2 remained lower. Corneal fluorescein staining score was obsserved in the early postoperative period and resolved by 6 months in most patients. Blink parameters normalized by the final follow-up. Conclusion: Cosmetic blepharoplasty, particularly combined upper–lower eyelid surgery, can induce transient dry eye symptoms that generally resolve within 6 months. Pre- and postoperative ocular surface management is essential to prevent complications and optimize outcomes.
