Abstract
PURPOSE: To evaluate the efficacy of intrastromal corneal ring segments implantation followed by same-day photorefractive keratectomy (PRK) and ultraviolet-A/riboflavin collagen cross-linking (CXL) in patients with keratoconus. METHODS: Four patients (five eyes) were included in the study. All patients first underwent femtosecond laser-enabled placement of intracorneal ring segments (Intacs, Addition Technology). Uncorrected (UDVA) and corrected distance visual acuity (CDVA) and keratometry readings remained stable for 6 months. Same-day PRK and CXL were subsequently performed in all patients. RESULTS: Six months after Intacs plus PRK/CXL, significant improvements were noted for UDVA, CDVA, spherical equivalent refraction, keratometry, and total aberrations. No patient lost lines of CDVA or developed haze. CONCLUSIONS: The combination of intracorneal ring segments implantation followed by sequential same-day PRK/CXL may be a reasonable option for improving visual acuity in select patients with keratoconus.

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
