Surgical Technique to Retrieve a Migrated Lester Jones Lacrimal Tube
Bibliographic record
Abstract
PURPOSE: To describe a technique for retrieving an inferomedially migrated Jones lacrimal tube. METHODS: The distal end of the migrated Jones tube is visualized directly via the nose. The tip of an endoilluminator (23 Gauge Constellation Vision Systems) is bent to form a 45° to 60° angle using a mosquito forceps and inserted into the distal opening of the tube. The endoilluminator is used to push the tube upward toward the original medial canthal opening and limit downward displacement as the caruncular area is surgically explored. The light transilluminating the tube facilitates its visualization and retrieval in the caruncular area. A new tube may be threaded through the same passage, or if the ostium is traumatized, through a new passage. RESULTS: This technique is time-efficient and has proven to be safe and successful in subsequent patients. CONCLUSIONS: The described technique aids in retrieving an inferomedially migrated Jones tube with minimal trauma to the surrounding structures.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
