Introduction: Severe ophthalmological infections (such as trachoma) were eradicated or put undercontrol by development of microbiology and anti-microbe therapy. Due to widespreadapplication of corticosteroids, non-selective application of antibiotics and increase innumber of HIV infected patients, opportunistic microorganisms are main causes ofophthalmological post-operative infections.
Objectives: To investigate population of microorganisms in periocular area and test efficiency of theapplication of perioperative antibiotics in cataract surgery patients.To establish algorithm for peri-operative preparation of patients and antibioticprophylactic therapy in cataract surgery patients.
Patients and method: Cataract surgery patients in Polyclinic “Oko” dr Karčić formed survey samplewhile microbiological tests were conducted in the Institute for microbiology “Nalaz” inSarajevo. Perioperative application of antibiotics included cleaning perioperative area andrinsing conjuctival saccus with Povidone-iodine solution, intracameral instillationof 3rd generation Cephalosporins, followed by post-operative local application ofTobramycin and combination of Neomycin, Polimyxin B and Dexamethasone.
Results:
Before surgery, 31% had sterile smears .Primary culture remained sterile at82,14% patients. In other patients, the following microorganisms were isolated:St.epidermidis: 62,07% , St. aureus: 10,34%, Streptococcus alpha haemoliticus:3,44%, G+ diplococcus: 3,44%, Diphtheroides: 10,34%, St.saprophyticus: 3.44%
After Povidone-iodine solution, culture remained sterile in 69,56% patients ;St.epidermidis: 26,09% (in sub-culture), G+diplococcus: 4,34%, St.aureus: 4,34%
Seven days after surgery, primary culture remained sterile in all patients.52,94% patientshad St.epidermidis in sub-culture.
Discussion:
Povidone-iodine, although potent, did not prove to be efficient antibiotic agent.
Substantial efficiency of intra and post-surgery application of antibiotics is noted incataract surgery patients.
Microbiologic analysis of smears generally shows normal eye flora. Introduction oftopical antibiotic therapy on the day of cataract surgery should be considered.
