Intraocular Lens Position Following In-the-Bag Implantation of Single-Piece Versus Three-Piece Acrylic Intraocular Lenses
Bibliographic record
Abstract
BACKGROUND AND OBJECTIVE: To report the position of the single-piece and three-piece intraocular lenses (IOLs) following in-the-bag implantation. PATIENTS AND METHODS: Forty patients with bilateral age-related cataracts were recruited from both tertiary hospital and private practice in Montréal, Canada. Patients received the single-piece IOL in one eye and the three-piece IOL contralaterally. Postoperative anterior chamber depth (ACD) and iris-to-IOL distance were evaluated using a Scheimpflug imaging system. RESULTS: Mean ACD was 4.21 ± 0.32 mm for the single-piece IOL and 3.94 ± 0.34 mm for the three-piece IOL. Mean iris-to-IOL distance was 0.70 ± 0.19 mm for the single-piece IOL and 0.44 ± 0.21 mm for the three-piece IOL. The difference between paired eyes was 0.26 ± 0.20 mm (P = .002) for ACD and 0.25 ± 0.21 mm (P < .001) for iris-to-IOL distance. CONCLUSION: The single-piece IOL was positioned more posteriorly to the iris and allowed for a greater ACD than the three-piece IOL.

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.
