Repeated Use of Transscleral Cyclophotocoagulation Laser G-Probes
Bibliographic record
Abstract
PURPOSE: To evaluate the energy transmission of transscleral cyclophotocoagulation laser G-probes after repeated use. METHODS: In this prospective study, eight new laser probes were each used for 30 transscleral cyclophotocoagulation (TSCPC) sessions in cadaver human eyes with the laser settings of 2000 mW power, 2000 milliseconds duration, and 18 shots. The laser power output was measured using a laser energy output meter before and after each TSCPC session, after swabbing the laser probe tip with alcohol, and finally after thorough cleaning by flushing 70% alcohol inside the plastic footplate tip and swabbing with alcohol the fiberoptic tip. Laser probes were inspected for deterioration. Statistical analysis was done using Analysis of Covariance (ANCOVA). RESULTS: The laser power output increased on average by 1.99 +/- 0.18 mW after each cycle (P < 0.01, 95% confidence interval: 1.63-2.35 mW, ANCOVA). No deterioration of the probes was found after 30 TSCPC and sterilization cycles. Laser energy output increased on average 6% (P < 0.01) from the baseline to the first TSCPC cycle. Probe number one broke during the tenth cycle and accordingly data was recorded for this probe until that cycle. CONCLUSION: G-probes not only remain fully functional after repeated use and sterilization with 70% alcohol but also slightly increase in energy output.

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.
