Introduction: Cataract surgery may result in preoperative and postoperative complications.1 Cataract surgery and other intraocular procedures have a higher incidence and more pronounced postoperative inflammatory reactions in diabetic patients. These reactions are associated with age and may be affected by surgical technique, intraoperative injury to adjacent structures such as iris, presence of antecedent ocular infection, and remnants of retained cortical material. Methodology: Study Design: Descriptive case series. Setting: Department of Ophthalmology, DHQ Hospital, Kasur. Duration: The study was conducted from June 2019 to December 2019. Sample Size: Sample size of 34 cases was included in the study. Sampling Technique: Non probability, consecutive sampling. Fifteen eyes from 15 cataract cases aged 30 ±15 years (group 1: range 15–50 years) received anterior chamber irrigation with heparin sodium (5 IU/cc) during operation and received 1 ml of heparin sodium (concentration 10 IU/ml) added to the irrigating solution of BSS (BSS Plus) whilst in 19 eyes from 19 cataract cases aged 39 ± 10 (group 2: range 29–49 years), BSS without heparin sodium was used. Results: The two groups were comparable in age and distribution of sex (Student t-test p > 0.05). There were no statistically significant differences between the two groups. Mild anterior chamber reaction was observed in only four patients in group 1, while nine cases of group 2 experienced marked anterior chamber reaction.
