Corneal biophysical changes after upper eyelid blepharoplasty and ptosis surgery: a review

Abstract

Upper eyelid surgeries, such as blepharoplasty and ptosis correction, are commonly performed procedures worldwide. This review examines the effects of these surgeries on ocular properties and visual function. A search of the PubMed and Google Scholar databases was conducted to identify relevant articles published after 2000. The results demonstrate that the ocular and adnexal organs function as a unified visual system, with changes in one component affecting the functions of others. Eyelid surgery can alter ocular properties and functions by modifying retinal lighting and ocular optics. These alterations can affect intraocular pressure estimation, corneal curvature, corneal epithelial thickness, refractive power of the cornea, and intraocular lens calculation. Additionally, eyelid surgery can exacerbate dry eye symptoms and impact contrast sensitivity, which is a significant factor in visual quality. Therefore, understanding these interactions is crucial before performing eyelid surgery and during follow-up. This review summarizes recent literature on the effects of upper eyelid surgery on corneal properties and visual function, emphasizing the importance of considering these factors when planning or undergoing such procedures.
