Most of the cataracts are age related or they can be related or they can be associated with other factors the development of cataract is mediated by number of factors. In senile cataract it appears that metabolic processes within the lens can cause an accumulation of water, alterations in lens fiber structure, these changes affect lens transparency causing vision changes. Objectives: To assess the pre test knowledge on home care management among the patients, To assess the effectiveness of Self Instructional Module on home care management and to find out the association between the level of knowledge on home care management with selected socio demographic variables of patients who undergone cataract surgery. Methodology: In this study Quasi –experimental one group pre test and post test design was used. It was conducted at Government hospital Kumbakonam. 50 Cataract patients who had satisfied the inclusion criteria were selected as sample by using simple random sampling technique. Results: The results of the study shows that in pre test the level of knowledge on home care Management among Patients under gone cataract surgery. Out of 50 patients 35 (70%) of them had inadequate knowledge and 12 (24%) of them had moderately adequate knowledge and only 3 (6%) of them had adequate level of knowledge. In post test the level of knowledge on home care management among Patients undergone cataract surgery. Out of 50 patients 5 (10 %) of them had inadequate knowledge and 20 (40%) of them had moderately adequate knowledge and 25 (50%) of them had Adequate level of knowledge. The chi – square test revealed that there was no significant association between the level of knowledge and the demographic variables.
