Topical thiotepa treatment for recurrent corneal haze after photorefractive keratectomy
Bibliographic record
Abstract
PURPOSE: To describe the use of topical thiotepa in the treatment of recurrent haze after photorefractive keratectomy (PRK). SETTING: Gimbel Eye Centre, Calgary, Alberta, Canada. METHODS: Five patients with recurrent haze after myopic PRK were retreated with phototherapeutic keratectomy and topical thiotepa. Before retreatment, the best corrected visual acuity (BCVA) ranged from 20/40 to 20/200. Follow-up ranged from 3 to to15 months. RESULTS: Haze, uncorrected visual acuity (UCVA), and BCVA improved in all patients. Three eyes had a UCVA of 20/20(-2) or better and a BCVA of 20/20(-1) or better. The other 2 eyes experienced regression of the myopia and astigmatism and had a BCVA of 20/25(-1) or better. CONCLUSION: Topical thiotepa appeared to be an effective treatment for recurrent corneal haze following myopic PRK.

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.
