Abstract:
Purpose:We investigated the effects of upper eyelid surgery on corneal higher-order aberrations and astigmatism.
Methods:We enrolled 38 patients (66 eyes) who underwent blepharoplasty and 48 (81 eyes) who underwent levator resection. The marginal reflex distance1 (MRD1), corneal astigmatism, and corneal higher-order aberrations were measured preoperatively, and at 6 months postoperatively, and the two groups were compared.
Results:Corneal astigmatism decreased significantly in the ptosis repair group (p < 0.001) but there was no significant change in the axis of astigmatism. Preoperative third-order and coma-like aberrations were significantly more common in the ptosis repair group than in the other group (p = 0.027 and p = 0.044, respectively); both decreased significantly after the operation (p = 0.030 and p = 0.006, respectively). The decrease in MRD1 and changes in the two aberrations showed a significantly stronger negative correlation in the ptosis repair group than in the other group (b = -0.186; p < 0.001 and b = -0.159; p < 0.001, respectively).
Conclusions:For patients with both cataract and ptosis, it is best to perform levator resection surgery before cataract surgery, because corneal higher-order aberrations and astigmatism are improved by levator resection. In turn, this reduces postoperative refractive error and improve vision quality.
