Sumario:PURPOSE: Early onset opacification of the lens (cataract) has been observed to be on the rise globally. This study was conducted to determine the various types of presenile cataract and to determine the probable risk factors associated with the occurrence of presenile cataract. MATERIALS AND METHODS: Patients in the age group of 18–40 years attending the Out-Patient Clinic of the Ophthalmology Department who were found to have presenile cataract were recruited as cases. An equal number of consecutive patients of the same age group were included in the control group. Those who gave consent to participate in the study were interviewed through a preformed questionnaire and underwent a complete ocular examination and set of blood investigations. The type of cataract was noted, data obtained were compiled, and examination and investigations done were documented and analyzed using frequency distribution and Chi-squared test. RESULTS: In total, 90 cases and 90 controls that fulfilled the inclusion criteria were recruited. Most common type of cataract was found to be posterior subcapsular cataract. Presenile cataract was observed to be significantly associated with tobacco intake (P = 0.035), hypercholesterolemia (P = 0.002), fuel exposure (P = 0.004), and lower socioeconomic status (P = <0.001). CONCLUSIONS: Tobacco chewing, hypercholesterolemia, and excessive fuel exposure are risk factors for early development of cataract.
