Persistent eyelid drooping after prior ptosis surgery is rarely a simple issue of eyelid height.
In most revision cases, the underlying problem involves inadequate levator advancement, loss of fixation, postoperative scarring, or altered muscle response following prior intervention.
Dr. Ahn begins every revision ptosis case with a comprehensive evaluation of levator function, Müller’s muscle contribution, eyelid crease mechanics, brow compensation, and scar-related restriction.
This detailed assessment allows him to determine not only how to correct the ptosis—but whether additional correction is safe and appropriate.
Revision surgery focuses on restoring effective eyelid opening while preserving smooth, coordinated movement between the eyelid and brow.
Dr. Ahn avoids aggressive elevation that can result in stiffness, lagophthalmos, or ocular surface exposure.
Instead, eyelid height, muscle tension, and fixation points are carefully recalibrated to achieve functional improvement that remains stable over time.
The objective is not maximal opening, but physiologic eyelid movement that appears natural at rest and during expression.
