Abstract

The cornea plays a crucial role in visual acuity due to its contribution of approximately two-thirds of the eyes total optical power. The anterior surface curvature of the cornea is primarily responsible for corneal refraction. Given that this surface is in direct contact with the eyelids, alterations in eyelid shape and function can result in changes to corneal refraction, steep and flat corneal meridians, refractive error, and corneal astigmatism. Various theories propose that upper eyelids cause a “band like pressure” on the cornea and may cause With the Rule astigmatism due to altered corneal shape. Several studies have recorded the refractive error, astigmatism and corneal topography changes produced by the ptotic eyelid on the cornea. Amblyopia has also been reported as a result of upper eyelid ptosis in children. Dry eye symptoms, an important post-eyelid surgery observation, may also worsen after blepharoptosis surgery as a result of various factors, including post-operative inflammation, chemosis, lagophthalmos, excessive orbicular denervation and resection, lid retraction, and dysfunction of the lacrimal pump system. It is known that these symptoms may be transient in the first few weeks and will likely resolve within 2–3 months after surgery
