Abstract
Abstract Drug delivery to the eye remains a challenge due to low compliance and high amounts of drug loss resulting from anatomical barriers. Contact lens‐based delivery systems offer many advantages since their increased corneal residence time can increase drug bioavailability. A releasable, sustained delivery system from a contact lens has been evaluated in the current work. Using a labile lactide spacer, comprised of poly(ethylene glycol) methacrylate, varying numbers of lactide units and succinic anhydride, a model drug, R‐roscovitine, was covalently incorporated into model silicone lenses (consisting of 80 mol% N , N ‐dimethylacrylamide and 20 mol% of a modified silicone). This enabled a greater amount of the drug to remain in the material following extraction with isopropyl alcohol, a common purification procedure used in lens manufacturing. The incorporation of the tether and drug did not substantially alter the bulk properties of the materials, with their water content remaining between 32% and 36% and their transmittance remaining at over 90% at 600 nm. Drug release from these materials exceeded 2 weeks, with the longer lactide tethers showing greater release as expected. This demonstrates that these covalently modified materials have the potential to be used to deliver drugs in a sustained manner. © 2022 Society of Industrial Chemistry.

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 it
