Comment on: Diagnosis and management of postrefractive surgery ectasia
Bibliographic record
Abstract
A review summarizing the diagnostic approaches and surgical treatment options for postoperative ectasia (POE) was recently published by Hatch et al.1 The article includes key corneal crosslinking (CXL) references, but a published CXL technique termed under-flap CXL (ufCXL) was not discussed.2 The current correspondence, therefore, aims to bring further updates to the POE literature. The innovative ufCXL procedure is performed under a previous laser in situ keratomileusis (LASIK) flap for early POE. The LASIK flap is opened, retracted, and protected. The exposed corneal stromal bed is soaked with riboflavin. Excess riboflavin is irrigated away; the flap is repositioned; and ultraviolet light is administered to the corneal surface. In a recent JRS article, visual outcomes were shown to be maintained with a significant decrease in refractive astigmatism and maximum keratometry 36 months after ufCXL.3 Endothelial cell counts remained normal.3 An ufCXL early intervention has the potential to halt ectasia progression, preserve vision, and minimize irregular corneal astigmatism and the need for complex visual rehabilitation. This technique has minimal patient discomfort, recovery, and downtime. Additional details on ufCXL can be found in letters, articles, and a book chapter.4–7 In summary, ufCXL can be another treatment option for early post-LASIK ectasia. The potential of minimizing the significant detrimental effects of progressive POE, with early ufCXL intervention, highlights the need to follow postoperative LASIK patients on a regular basis.

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.
