This article evaluates the effects of Muller's muscle-conjunctival resection (MMCR) on ocular surface scores and dry eye symptoms. Forty-six patients were enrolled in the study. Eighteen underwent bilateral upper eyelid skin excision with MMCR and 28 underwent bilateral upper eyelid skin-only excision (control group). The Salisbury Eye Evaluation Questionnaire and an ocular surface evaluation protocol consisting of Schirmer's test, tear break-up time (TBUT), fluorescein and rose bengal corneal staining were performed during the pre-operative consultation and on postoperative days 7, 30, and 90. Improvement in symptoms questionnaire scores from baseline was observed on postoperative day 90 in the blepharoplasty plus MMCR group. There was no change in questionnaire scores in patients who underwent blepharoplasty alone. No between-group difference in Schirmer's test, TBUT, or fluorescein and rose bengal staining was found at any time point. In the blepharoplasty-only (control group), the fluorescein staining score was reduced on postoperative day 30 as compared to baseline, but not on day 90. In this sample, addition of MMCR to upper eyelid blepharoplasty did not worsen ocular surface scores or dry eye symptoms.
