A six-year study was carried out to compare the prevalence of cataract in the Kerala towns of Kottayam and Pathanamthitta. A hospital-based study was conducted from April 2005 to March 2011 to determine the prevalence of cataracts in the general population, gender prevalence, and prevalence in different age groups. The data came from the ophthalmology departments of district hospitals and two private hospitals in the districts of Pathanamthitta and Kottayam, as well as the Directorate of Health in Thiruvananthapuram. The burden of blindness is greater in developing countries’ remote rural communities. However, prevalence in Pathanamthitta district decreased significantly from 0.40 percent to 0.36 percent (p=0.0024). Gender prevalence is significantly higher in females than males in Kottayam (61.6 percent, 0.0000326) and Pathanamthitta (59 percent, 0.00014), indicating that females have more cataract. When compared to all other age groups, the age group of 71-80 years in Kottayam (36.6 percent, 0.000072) and Pathanamthitta (33.6 percent, 0.000312) had the highest prevalence. groups. Prevalence of congenital cataract (0-15) is very less in Kottayam (1.2 percent ) and Pathanamthitta(0.9 percent ). (0.9 percent ). The decrease in prevalence rate in Pathanamthitta district is attributed to a decrease in population. Cataract blindness in Kerala can only be effectively managed by developing effective strategies to reduce the incidence of blinding cataract. To some extent, the current analysis of cataract prevalence in Kerala may shed light on the severity of cataract incidence in the state.
