Blepharoplasty significantly alters corneal biomechanics and improves tear film stability
Upper eyelid blepharoplasty can significantly alter corneal biomechanics, particularly reducing corneal hysteresis, and improving tear film stability, according to a study.
These changes, especially the reduction in corneal hysteresis, may be important for patients who require follow-up for conditions like glaucoma after the surgery.
The prospective study included 60 eyes from 30 patients, with evaluations conducted preoperatively and at 1- and 3-months post-surgery. Key metrics included corneal hysteresis, corneal resistance factor, intraocular pressure, tear breakup time, and Ocular Surface Disease Index scores.
Results showed a significant reduction in corneal hysteresis postoperatively, with values decreasing at both the 1-month (P = 0.011) and 3-month (p = 0.021) marks. Corneal resistance factor and intraocular pressure also decreased but without statistical significance. Tear breakup time improved significantly in the first month (P = 0.024), and fewer patients experienced dry eye symptoms.
