Fracture and dislocation of a glass intraocular lens optic as a complication of neodymium:YAG laser posterior capsulotomy: Case report and literature review
Bibliographic record
Abstract
UNLABELLED: An 83-year-old man presented with a 1-year history of blurry vision in his left eye. Bilateral cataract surgery and ciliary sulcus posterior chamber intraocular lens (IOL) implantation had been performed 11 years earlier. The corrected distance visual acuity (CDVA) was 20/60 in the left eye. Slitlamp examination revealed moderate posterior capsule opacification. Neodymium:YAG laser posterior capsulotomy was performed and complicated by IOL fracture and immediate dislocation of optic fragments into the anterior chamber. An IOL exchange was performed, and the damaged IOL was removed in 7 pieces. A 3-piece acrylic IOL was suture fixated to the posterior iris. Pathologic analysis showed that the damaged IOL was made of glass supported by a polyimide frame. Twelve months after the IOL exchange, the CDVA was 20/60.

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.
