Clinical Outcomes of Pars Plana Vitrectomy and Polytetrafluoroethylene (Gore-Tex) Scleral Fixation of a Monofocal Aspheric Intraocular Lens (Akreos AO60)
Bibliographic record
Abstract
Purpose: To evaluate the visual outcomes and complications with a polytetrafluoroethylene (Gore-Tex)-fixated intraocular lens (IOL) (Akreos AO60, Bausch + Lomb). Methods: Eyes with inadequate capsule support for in-the-bag IOL implantation had pars plana vitrectomy (PPV) and IOL placement at a single center. The main outcome measures were the postoperative visual acuity (VA) and complication rates. Results: During the study, 783 surgeries were performed. The mean visual acuity gain was 28.5 Early Treatment Diabetic Retinopathy Study letters ( P < .01), with a mean time to best VA of 3.05 months. Statistical hypotony (intraocular pressure <6.5 mm Hg) was present in 214 cases (27.3%), and clinical features of hypotony were present in 46 cases. Five percent of the complications were directly related to the IOL. There were 3 cases of IOL opacification, 2 with silicone oil endotamponade and 1 with perfluoropropane endotamponade. Conclusions: PPV with Akreos IOL implantation was an effective technique for secondary IOL placement. Complications directly related to the IOL were uncommon.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
