Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 1; Drug: Enoxaparin. It is administered during the cataract surgery. The mode of the administration is intraocular infusion.

Enoxaparin 40 mg/500 ml in Balanced Salt Solution
Other name: clexane (Aventis)

Intervention code [1] 287480 0
Treatment: Drugs
Comparator / control treatment
Arm 2; Balanced Salt Solution is used for the intraocular infusion during the cataract surgery.

Balanced Salt Solution is an isotonic solution for use in irrigating tissues of the eye.

Balanced Salt Solution is a sterile solution, each mL containing sodium chloride (NaCl) 0.64%, potassium chloride (KCl) 0.075%, calcium chloride dihydrate (CaCl2·2H2O) 0.048%, magnesium chloride hexahydrate (MgCl2·6H2O) 0.03%, sodium acetate trihydrate (C2H3NaO2·3H2O) 0.39%, sodium citrate dihydrate (C6H5Na3O7·2H2O) 0.17%, sodium hydroxide and/or hydrochloric acid (to adjust pH), and water for injection.

Statistical methods / analysis
In the absence of available literature, we used data from a pilot study of 10 patients (10 eyes in each group) to arrive the sample size. The main outcome measure was the presence of grade 2 anterior chamber cells in the first week after the surgery. In the first week, cells with grade 2 were seen 10% of the eyes in group1 (enoxaparin group), 50% of the eyes in group 2 (no enoxaparin group). To detect the difference of 35% between two groups, using the test of proportions at 5% level of significance, a sample size of 30 in each group was necessary to achieve 80% power

Mann-Whitney U test and the chi-square test are used to investigate differences in terms of gender and age. Fisher's exact test, chi-square test and Mann-Whitney U test are used to compare post-operative inflammation between groups.
