Area of Science:

  • Ophthalmology
  • Surgical Techniques

Background:

  • Mature cataracts pose surgical challenges.
  • Existing techniques may be insufficient for hypermature cataracts.

Purpose of the Study:

  • To describe and evaluate a modified surgical technique for anterior capsulotomy and phacoemulsification in hypermature cataracts.

Main Methods:

  • The technique involves inferior linear capsulotomy, viscoelastic inflation, reverse triangular capsulotomy, and in-the-bag bimanual sculpting.
  • A 5 mm x 6 mm posterior chamber intraocular lens was implanted with minimal wound closure.

Main Results:

  • Successful application in 20 hypermature cataract cases.
  • Mean phacoemulsification time was 3.46 minutes.

  • Postoperative visual acuity ranged from 20/20 to 20/60, with a median of 20/40.

    • Conclusions:

    • The modified technique is effective for hypermature cataracts.
    • It offers efficient phacoemulsification and good visual results.
    • This approach warrants consideration for complex cataract cases.
