Methodology:-The data’s collected from registers of ophthalmology department of district hospital and two private hospitals in Thiruvananthapuram, Kollam and Alappuzha districts to access the gender prevalence and prevalence of different age groups. The total number of cataract operation carried out in these districts were collected from Directorate of Health, Thiruvananthapuram to evaluate the prevalence among the total population Significance of cataract prevalence was analyzed using MATLAB and SPSS statistical package Result: Overall survey indicates that cataract prevalence among the total population increased in Thiruvananthapuram, Kollam and Alappuzha districts within six years. The prevalence increased significantly in Thiruvananthapuram, Kollam, and Alappuzha from 0.35%, 0.24%, 0.26% to 0.44% (p=0.00015), 0.37% (p=0.0010) and 0.51% (p=0.000157). Female gender prevalence was significantly higher in all the districts. Prevalence among females were Thiruvananthapuram (51.9%, p=0.004), Alappuzha (60.6%, p=0.0000344) and Kollam (58.2%, p=0.000214). Conclusion: - The present study has shown that Kerala has been able to arrest the increasing prevalence of blindness by improving the general health conditions of individuals and by decreasing the population growth. Cataract blindness in Kerala can be effectively controlled only if effective strategies are developed to reduce the incidence of blinding cataract.
