Objectives: To know the prevalence and predisposing risk factors of HBVand HCV in patients undergoing ocular surgery. Study Design: Descriptive study. Setting:Department of Ophthalmology Khyber Medical University Institute of Medical Sciences / K.D.ATeaching Hospital Kohat. Period: January 2015 to December 2016. Materials and Methods: Alladmitted patients in eye ward for surgery. Informed consent was taken from patients. Detailedhistory including surgical, medical treatment, blood transfusion and other relevant was taken. Allthose patients who were not previously diagnosed as HBV and HCV positive were included in thestudy. ICT method was used for screening. Those who were positive with ICT were confirmed byEliza test. Eliza negative patients were excluded. During these two years total 2547 patients withmean age of 63.4 years were admitted in eye ward. Results: By ICT method 43(1.68%) patientswere HBC positive in which 24(55.81%) were male and19(44.18%) were female. 121(4.75%)patients were HCV positive, out of them 44(36.36%) were male and 77(63.63%) were female.All positive patients were confirmed by ELIZA test. Regarding predisposing risk factors. in HBVpositive, 13(30.23%) patients had history of major surgical procedure, 9(20.93%) patients haddental extraction, 6(13.95%) had blood transfusion, 6(13. 95%) had quackery injection with nondisposable syringes, 2(4.65%) patients had routine face and armpit shave in barber shops andno significant history in 7(16.27%) patients. In HCV positive, 29(23.96%) patients had history ofmajor surgical procedure, 22(18.18%) patients had blood transfusion, 18(14.87%) patients haddental extraction, 16 (13.22%) patients had history of injection by quack using non disposablesyringe, 13(10.74%)had routine face and armpit shave in barber shops and 23(19.00%) patientshad no significant history. Conclusion: HBV and HCV are common among community. HCV ismore prevalent as compared to HBV. Every patient should be screened before surgery.
