EFFICACY OF TOPICAL 0.1% DEXAMETHASONE FOR THREE WEEKS AFTER UNCOMPLICATED LOW-RISK CATARACT EXTRACTION IN TERMS OF AQUEOUS FLARE AND CELLULAR TYNDALL ASSESSMENT
Bibliographic record
Abstract
Background: Cataract extraction is routinely followed by a variable degree of anterior chamber inflammation, even after uncomplicated surgery. Topical corticosteroids remain a common postoperative choice because they reduce inflammatory activity and support visual recovery. Aqueous flare and cellular Tyndall assessment provide clinically useful indicators of blood-aqueous barrier disturbance and intraocular inflammation. This study evaluated whether a three-week course of topical 0.1% dexamethasone effectively controlled postoperative inflammation in low-risk cataract patients. Objective: To determine the efficacy of topical 0.1% dexamethasone administered for three weeks after uncomplicated low-risk cataract extraction in terms of aqueous flare and cellular Tyndall assessment. Methods: This descriptive case series was conducted in the Department of Ophthalmology, Mayo Hospital, Lahore, from 11 May 2023 to 11 October 2023. A total of 80 patients aged 40–70 years with senile cataract planned for uncomplicated cataract extraction with intraocular lens implantation were enrolled through non-probability consecutive sampling. Patients with uncontrolled diabetes, uncontrolled hypertension, ischemic heart disease, bronchial asthma, allergy, immunological disease, systemic steroid use, anticoagulant therapy, complicated cataract, mature cataract, lens-induced glaucoma, poor compliance, or intraoperative complications were excluded. Preoperative assessment included Snellen visual acuity, non-contact air-puff tonometry, and slit-lamp examination. All surgeries were performed by a single surgeon using standardized techniques. Postoperatively, topical 0.1% dexamethasone was prescribed for three weeks. Anterior chamber cells and flare were assessed using Hogan’s slit-lamp grading system. Data were analyzed using SPSS version 25. Results: The mean age was 57.63 ± 6.55 years. Of 80 patients, 45 were male and 35 were female. Right-eye surgery was performed in 36 patients, while 44 underwent left-eye surgery. The mean anterior chamber cell value was 0.05 ± 0.150. Overall efficacy was observed in 72 patients, while 8 patients did not achieve efficacy. Efficacy was 88.9% in patients aged 40–55 years and 90.9% in patients aged 56–70 years. Male and female efficacy rates were 93.3% and 85.7%, respectively. Right-eye and left-eye efficacy rates were 88.9% and 90.9%, respectively. Efficacy was 77.8% in nuclear sclerosis grade 2 and 96.2% in nuclear sclerosis grade 3, with a statistically significant association. Conclusion: Topical 0.1% dexamethasone administered for three weeks after uncomplicated low-risk cataract extraction was effective in controlling postoperative anterior chamber inflammation. The findings support its practical use as a postoperative anti-inflammatory regimen in selected low-risk cataract patients.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
