Abstract
PURPOSE: To review one surgeon's experience with posterior lamellar grafting for lower eyelid elevation over a 15-year period, comparing the success of different posterior lamellar grafts used in 4 etiology groups. METHODS: A retrospective chart review of 400 patients (659 eyelids) was conducted. Patients were grouped into thyroid ophthalmopathy, previous surgery, trauma, and idiopathic causes. Three graft types were used: hard palate mucosa, free tarsoconjunctival, and free scleral. Objective measurements of lagophthalmos, scleral show, and superficial punctate keratopathy, and subjective patient symptoms, preoperatively and postoperatively were compared between graft types and etiologic groups. Complications were tabulated and compared between groups, as was any need for further surgery. The mean follow-up interval was 16.5 months. The main outcome measures were objective measurements of lagophthalmos, scleral show, and superficial punctate keratopathy. RESULTS: A mean reduction in lagophthalmos ( approximately 0.5 mm), superficial punctate keratopathy (mean score reduction = 0.2, on a scale of 1-3), and scleral show ( approximately 1.3 mm) was demonstrated for all etiology groups and graft types. Furthermore, 90% of patients subjectively reported a reduction of 1 to 3 symptoms. Hard palate mucosa grafts were more likely to be used than tarsoconjunctival grafts in cases with one or more previous surgeries (p < 0.001). Complications were more common with tarsoconjunctival grafts (except for bleeding), but the difference was statistically significant only for wound dehiscence (p = 0.004). CONCLUSIONS: Lower eyelid retraction repair with posterior lamellar grafting and lateral eyelid tightening can be recommended with confidence for eyelid retraction patients because most improved subjectively and by objective examination.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
