Long-term Outcome of Surgical Treatment for Late Intraocular Lens Dislocation Associated With High Intraocular Pressure: A Case Series
Bibliographic record
Abstract
PURPOSE: To demonstrate the long-term safety and efficacy of transscleral intraocular lens (IOL) fixation combined with an Ahmed glaucoma drainage device implantation for patients with late IOL dislocation and high intraocular pressure (IOP). METHODS: This is a retrospective report of a series of patients who underwent this combined surgery. The main outcome variables studied were change in visual acuity (VA), IOP, and number of medications compared with preoperative levels. Surgical failure was defined as a decrease in VA of at least 3 Snellen lines, IOP above 20 mm Hg or IOP reduction <25% from preoperative levels at ≥2 consecutive visits, at least 2 months apart. RESULTS: Eleven patients with median age of 83 years (range, 77 to 92 y) were included in the study. All patients had a previous diagnosis of pseudoexfoliation. After a median follow-up time of 1.75 years (range, 0.83 to 2.5 y), the median IOP decreased from 33 mm Hg (range, 24 to 47 mm Hg) to 13 mm Hg (range, 5 to 16 mm Hg; P<0.01). The number of glaucoma medications also decreased from 3 (range, 1 to 4) to 2 (range, 0 to 4; P=0.03). The median log MAR VA improved from 0.77 (range, 0.3 to 2) preoperatively to 0.44 (range, 0 to 3) postoperatively (P=0.27).Four patients had postoperatory surgical complications: choroidal effusion (2), vitreous hemorrhage and hyphema (1), vertical diplopia (1). The survival probability over 2.5 years was 90.9% (confidence interval, 75.4%-100%). CONCLUSION: Transscleral IOL fixation associated with Ahmed glaucoma drainage device implantation is a safe and effective surgical option for patients with late IOL dislocation and elevated IOP.

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.
