Summary

This study shows that 23-gauge capsulorrhexis forceps with a cystotome function are effective for complex cataract surgeries. These forceps are particularly useful in patients with shallow anterior chambers or lens subluxation, improving surgical outcomes.

Area of Science:

  • Ophthalmology
  • Surgical Instrumentation

Background:

  • Complex cataract surgeries present unique challenges, especially in patients with pre-existing conditions like glaucoma or lens instability.
  • Standard surgical tools may be inadequate for these intricate procedures, necessitating specialized instruments.

Purpose of the Study:

  • To evaluate the operational performance of 23-gauge capsulorrhexis forceps with an integrated cystotome function.
  • To assess the efficacy of these forceps in complex cataract surgery cases.

Main Methods:

  • The 23-gauge capsulorrhexis forceps were utilized in six complex cataract surgery cases.
  • Cases included patients with shallow anterior chambers, closed-angle glaucoma, poor mydriasis, and lens subluxation.
  • Goniotomy angle and mydriasis levels were measured in all patients.

Main Results:

  • The forceps demonstrated effectiveness in all evaluated cases, including those with shallow anterior chambers and glaucoma.
  • Despite lens subluxation in five cases during continuous curvilinear capsulorrhexis (CCC), successful intraocular lens (IOL) implantation in the capsular bag was achieved.
  • The instrument's dual function as forceps and a 55-degree angulated cystotome needle proved advantageous.

Conclusions:

  • The 23-gauge capsulorrhexis forceps with a cystotome function are a valuable tool for complex cataract surgeries.
  • These forceps are particularly effective in managing challenging cases, such as post-glaucoma surgery cataract extraction and those with lens subluxation.
