Dry Eye in Upper Eyelid Surgery: Muscle Versus Fat Removal

Not Applicable

• Conditions: Eye Disorders

• Registration Number: NCT06985264
• Lead Sponsor: Mersin Training and Research Hospital

Brief Summary

The aim of this study is to compare the effects of two different surgical techniques (Orbicularis Oculi excision and Orbicularis Oculi + Fat excision) applied in upper blepharoplasty surgery on dry eye and to evaluate the effects of these techniques on ocular surface health. 142 patients (71 patients in each group) who met the inclusion and exclusion criteria between 01.05.2025 and 31.12.2025 in Mersin City Education and Research Hospital Eye Diseases Clinic will be included in this study. This study is a prospective, survey study and aims to evaluate the effects of two different surgical techniques (Orbicularis Oculi excision only and Orbicularis Oculi + Fat excision) applied in upper blepharoplasty surgery on postoperative dry eye symptoms. The study will be conducted on patients who are currently scheduled for upper blepharoplasty surgery and no additional surgical procedures or interventions will be applied to the patients. Data collection will be done by a survey study and retrospective recording of routine clinical examinations.

The collected data will be used to analyze the differences in dry eye parameters between the two surgical techniques. OSDI scores, BUT times, Oxford staining degrees, Schirmer test results and visual acuity values will be compared at pre- and postoperative time points. Differences between groups will be analyzed by one-tailed independent samples t-test and p\<0.05 will be considered significant. These analyses will be performed to determine the effect of surgical techniques on dry eye symptoms.

Primary Outcome Measures

Name	Time	Method
Ocular Surface Disease Index (OSDI)	Preoperative, postoperative 1st month, 3rd month and 6th month Ocular Surface Disease Index (OSDI) score survey will be conducted.	The OSDI, which was created by the Outcomes Research Group at Allergan Inc in order to quickly assess the symptoms of ocular irritation in dry eye disease and how they affect functioning related to vision. This 12-item questionnaire assesses dry eye symptoms and the effects it has on vision-related function in the past week of the patient's life. The questionnaire has 3 subscales: ocular symptoms, vision-related function, and environmental triggers. Patients rate their responses on a 0 to 4 scale with 0 corresponding to "none of the time" and 4 corresponding to "all of the time." A final score is calculated which ranges from 0 to 100 with scores 0 to 12 representing normal, 13 to 22 representing mild dry eye disease, 23 to 32 representing moderate dry eye disease, and greater than 33 representing severe dry eye disease.
