Study to the Effect of Involutional Blepharoptosis Surgery Using Objective and Subjective Parameters.

Area of Science:

• Ophthalmology
• Oculoplastics
• Dry Eye Disease

Background:

• Involutional blepharoptosis (IB) can significantly impact dry eye symptoms and ocular comfort.
• Surgical correction of IB aims to improve eyelid function and aesthetics.

Purpose of the Study:

• To investigate the effects of involutional blepharoptosis surgery on dry eye symptoms using objective and subjective measures.
• To determine optimal postoperative outcomes for IB surgery concerning ocular surface health.

Main Methods:

• Levator advancement surgery for IB was performed on 125 eyes (65 patients).
• Subjective assessments included dry eye-related quality of life scores (DEQS) and patient-reported eye comfort.
• Objective assessments included marginal reflex distance-1 (MRD-1), tear film breakup time, and superficial keratopathy (SPK) evaluation.

Main Results:

• Subjective improvements in dry eye symptoms and comfort correlated with increased MRD-1 post-surgery.
• Objective analysis indicated a risk of SPK when postoperative MRD-1 exceeded 3mm.
• Tear film stability was also assessed as a measure of ocular surface health.

Conclusions:

• Involutional blepharoptosis surgery should aim to increase MRD-1 while maintaining ocular surface health.
• A postoperative MRD-1 value below 3mm is suggested for safe and effective IB surgery.
• Balancing eyelid elevation with ocular surface integrity is essential for successful outcomes.
