Visual outcomes and safety profile of retropupillary iris-claw Artisan intraocular lens implants
Bibliographic record
Abstract
OBJECTIVE: The Artisan is an iris-claw intraocular lens (IOL) that can be used to correct aphakia in eyes with insufficient capsular support. This study aims to evaluate long-term visual outcomes and complications following retropupillary implantation of the Artisan IOL at a Canadian centre. DESIGN: Retrospective chart review. PARTICIPANTS: Patients who underwent implantation of an Artisan IOL at a tertiary Canadian center between January 2013 and December 2021. METHODS: Retrospective chart review was performed, and clinical outcomes at postoperative follow-up visits were summarized. Outcomes included postoperative best corrected and uncorrected distance visual acuity (BCDVA and UCDVA), intraocular pressure (IOP), as well as intraoperative and postoperative complications. RESULTS: Seventy-three eyes of 67 patients were evaluated. Mean follow-up duration was 11 months (range: 1-63 months). Common indications for Artisan implantation were IOL dislocation (n = 50; 68.5%) and aphakia (n = 23; 31.5%). Causes for IOL dislocation included idiopathic zonular weakness (n = 25; 34.2%), pseudo-exfoliation (n = 14; 19.2%), surgical complications (n = 6; 8.2%), trauma (n = 3; 4.1%), and Marfan syndrome (n = 2; 2.7%). Causes for aphakia included complicated cataract surgery (n = 20; 27.4%), ocular trauma (n = 2; 2.7%), and post-vitrectomy and lensectomy (n = 1; 1.4%). Average BCDVA (logMAR) was 0.62 ± 0.56 at preop, 0.46 ± 0.55 at 3 months postop, and 0.43 ± 0.55 at 9-12 months (p < 0.0001). Average UCDVA (logMAR) was 1.19 ± 0.68 at preop, 0.65 ± 0.60 at 3 months postop, and 0.42 ± 0.46 at 9-12 months (p < 0.0001). IOP did not differ significantly in follow-up. Pupil ovalization (n = 11, 15.1%) was the most common complication. CONCLUSIONS: Outcomes demonstrated favourable efficacy and safety of retropupillary Artisan IOL as an option for providing adequate visual rehabilitation for patients without sufficient capsular support.

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.
