Purpose: To study the changes of the visual function and ocular and systemic symptoms following blepharoptosis surgery.Methods: Seventy-eight involutional blepharoptosis patients (72.1 ± 6.4 years) underwent levator advancement procedure. Before and at 2 months after the surgery, OPD-Scan III (Nidek) was used to measure corneal astigmatism, total higher order aberrations (HOAs), and area ratio (AR), an index of the objective contrast sensitivity. FVA-100 (Nidek) was used to determine the functional visual acuity (FVA) and visual maintenance ratio (VMR). The ocular and systemic symptoms were also determined by a questionnaire using visual analogue scale (VAS) scores.Results: Before surgery, the corneal astigmatism, HOAs, AR, FVA, and VMR were 1.56 ± 0.52 diopters (D), 0.23 ± 0.24 µm, 14.8 ± 4.2%, 0.68 ± 0.32 logMAR units and 0.76 ± 0.06, respectively. After surgery, these values were 1.29 ± 0.41 D, 0.19 ± 0.21 µm, 18.6 ± 3.4%, 0.31 ± 0.18 logMAR units and 0.88 ± 0.03, respectively. Corneal astigmatism and HOAs were significantly reduced after surgery (P=0.007 and P=0.023, paired t test, respectively), and AR, FVA and VMR were significantly improved after surgery (P=0.033, P=0.012 and P=0.016, respectively). The VAS scores significantly improved after surgery, and this improvement was positively and significantly correlated with the increase of the AR (r=0.421, P=0.003) and the VMR (r=0.497, P =0.005).Conclusions: Blepharoptosis surgery is visual functionally beneficial and can help to reduce the ocular and systemic symptoms.
