Summary

Gentian violet staining improved anterior capsule visualization during cataract surgery in rats and humans, with no significant histopathological changes observed. Mild corneal edema was a potential adverse effect.

Area of Science:

  • Ophthalmology
  • Histopathology
  • Surgical Techniques

Background:

  • Cataract surgery, specifically continuous curvilinear capsulorhexis (CCC), requires clear visualization of the anterior capsule.
  • Mature white cataracts pose challenges for visualizing the anterior capsule during CCC.

Purpose of the Study:

  • To assess histopathological changes from gentian violet anterior chamber injections in rats.
  • To evaluate gentian violet as a staining agent for anterior capsule visualization during CCC in human cataract surgery.

Main Methods:

  • Rats received anterior chamber injections of gentian violet (0.01%, 0.001%) or balanced salt solution (BSS), followed by histopathological examination.
  • Human eyes with white mature cataracts underwent anterior capsule staining with gentian violet solutions prior to CCC, with outcomes and complications monitored.

Main Results:

  • No significant histopathological changes were noted in rat eyes post-injection.
  • CCC was successfully completed in all human cases.
  • Gentian violet 0.01% offered better anterior capsule visualization; mild corneal edema and transient inflammation were observed postoperatively.

Conclusions:

  • Low-concentration gentian violet solutions (0.01%, 0.001%) demonstrated no significant toxic effects on ocular tissues.
  • The gentian violet staining technique is practical for enhancing anterior capsule visibility during CCC.
  • Potential adverse effects include mild corneal edema, necessitating careful consideration.
