A novel technique using a modified cannula safely cleans the posterior lens capsule during cataract surgery. This method prevents visual impairment after extracapsular cataract extraction, with over 300 successful procedures.

Area of Science:

  • Ophthalmology
  • Microsurgery
  • Cataract Surgery

Background:

  • Posterior capsule opacification is a common complication after cataract surgery.
  • Maintaining clear vision post-operatively is crucial for patient outcomes.

Purpose of the Study:

  • To describe a simple and safe method for cleaning the posterior lens capsule during extracapsular cataract extraction.
  • To present a technique for polishing posterior capsule opacities in a deep anterior chamber.

Main Methods:

  • A straight 20-gauge cannula with a 0.3 mm anterior aspiration port was utilized.
  • The cannula was attached to a syringe with the piston removed for controlled aspiration.
  • This setup facilitated safe polishing of the posterior capsule.

Main Results:

  • The described method allows for safe and effective cleaning of the posterior lens capsule.
  • The technique was successfully performed in over 300 cataract microsurgery operations.
  • No early postoperative visual impairment related to capsule cleaning was reported in the series.

Conclusions:

  • The modified cannula technique offers a safe and simple approach to managing posterior capsule opacities.
  • This method is effective in preventing visual impairment following extracapsular cataract extraction.
  • The procedure is well-tolerated and has a proven track record in a significant number of surgeries.
