Pretreating the eye with nonsteroidal anti-inflammatory drugs (NSAIDs) before cataract surgery significantly reduced initial postoperative inflammation. This proactive approach offers a new strategy for managing post-surgical eye inflammation.

Area of Science:

  • Ophthalmology
  • Pharmacology

Background:

  • Postoperative inflammation is a common concern following ocular surgeries like cataract extraction.
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) are typically used after surgery to manage inflammation.
  • The mechanism of NSAIDs involves inhibiting prostaglandin synthesis, key mediators of inflammation.

Purpose of the Study:

  • To investigate the efficacy of preoperative nonsteroidal anti-inflammatory drug (NSAID) administration in mitigating early postoperative inflammation after cataract surgery.
  • To compare the effects of different NSAID pretreatment regimens on ocular inflammation.

Main Methods:

  • A prospective study involving 60 patients undergoing phacoemulsification with silicone lens implantation.
  • Patients were randomly assigned to three groups: preoperative NSAID treatment, intraoperative NSAID administration only, or no NSAID treatment.

  • Postoperative inflammation was quantified using a laser cell and flare meter on postoperative day 1 and at 1 week.

    • Main Results:

    • The group pretreated with NSAIDs (Group A) showed a statistically significant reduction in mean flare scores on postoperative day 1 compared to the no-treatment group (Group C).
    • No significant differences in cell scores were observed on day 1 or in cell/flare scores at 1 week across all groups.
    • While Group A had lower flare scores than Group B (intraoperative NSAID only), this difference was not statistically significant.

    Conclusions:

    • Pretreatment with NSAIDs prior to cataract surgery is effective in reducing initial postoperative inflammation.
    • This finding suggests a potential benefit of proactive anti-inflammatory management in ophthalmic surgery.
