Comparison of visual results with accommodating intraocular lenses versus mini-monovision with a monofocal intraocular lens
Bibliographic record
Abstract
PURPOSE: To compare near vision and quality of vision after controlling for pseudoaccommodation in patients with single-optic accommodating intraocular lenses (IOLs) or monofocal IOLs targeted for mini-monovision. SETTING: Clinical practice. DESIGN: Prospective randomized controlled clinical trial. METHODS: Patients were randomized to bilateral implantation of the Crystalens HD silicone accommodating IOL, the Tetraflex acrylic accommodating IOL, or the Tecnis 1-piece monofocal (nonaccommodating) control IOL. The target refraction for the control group was mini-monovision (-0.25 diopter [D] and -0.75 D). In the accommodating IOL groups, manufacturer recommendations were followed; that is, a target refraction of mini-monovision (-0.25 D and -0.75 D) in the acrylic accommodating group and +0.25 D in the silicone accommodating group. Pupil size and anterior corneal spherical aberration were measured preoperatively. Main outcome measures were binocular target refraction corrected near vision and contrast sensitivity 3 months postoperatively. RESULTS: There were no statistically significant differences between the 3 groups in age, photopic or mesopic pupil size, anterior corneal spherical aberration, corneal astigmatism, or the power of the IOLs implanted. Binocular distance visual acuity at 4 m was 20/20(-) in all groups, intermediate vision was approximately 20/25, and near vision was 20/40 to 20/50. There were no statistically significant differences between the 3 groups in visual acuity or contrast sensitivity. CONCLUSION: Single-optic accommodating IOLs did not offer a significant advantage in near visual acuity over mini-monovision with a monofocal (nonaccommodating) 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.
