    Prophylactic antibiotic treatment in senile lens extraction did not prevent infections but reduced pathogenic cultures. A chloramphenicol and polymyxin B sulfate mixture showed superiority over sulfacetamide.

    Area of Science:

    • Ophthalmology
    • Microbiology
    • Pharmacology

    Background:

    • Senile cataracts are a common cause of vision impairment.
    • Lens extraction is a surgical procedure to remove cataracts.
    • Postoperative infections are a potential risk following ocular surgery.

    Purpose of the Study:

    • To evaluate the efficacy of preoperative cultures, sensitivity tests, and prophylactic antibiotic treatment in senile, uncomplicated lens extractions.
    • To compare the effectiveness of sulfacetamide versus a chloramphenicol and polymyxin B sulfate mixture for preoperative antibiotic prophylaxis.
    • To assess the impact of antibiotic prophylaxis on the incidence of pathogenic cultures and postoperative infections.

    Main Methods:

    • A prospective study involving senile patients undergoing uncomplicated lens extraction.

  • Group 1 received preoperative antibiotic treatment (sulfacetamide or chloramphenicol/polymyxin B sulfate) for one week, followed by postoperative penicillin and streptomycin injections.
  • Group 2 (control) received no antibiotic treatment. Both groups were monitored for postoperative infections and pathogenic cultures.

    • Main Results:

    • No postoperative infections occurred in either the treated or control groups.
    • The treated group showed a significantly lower number of pathogenic cultures compared to the untreated control group.
    • The combination of chloramphenicol and polymyxin B sulfate was more effective than sulfacetamide in reducing pathogenic cultures.

    Conclusions:

    • While prophylactic antibiotics did not eliminate postoperative infections in this cohort, they significantly reduced the presence of pathogenic bacteria.
    • The combination antibiotic regimen (chloramphenicol and polymyxin B sulfate) demonstrated superior efficacy over sulfacetamide for preoperative prophylaxis.
    • Further research may be warranted to optimize antibiotic strategies in lens extraction procedures.
