Phacomorphic glaucoma presents surgical challenges. A novel technique using viscoelastic and needle aspiration allows safe capsulorhexis and cataract surgery, improving outcomes for this condition.

Area of Science:

  • Ophthalmology
  • Glaucoma Surgery
  • Cataract Surgery

Background:

  • Phacomorphic glaucoma is prevalent in developing nations.
  • Standard extracapsular cataract extraction with sulcus-fixated intraocular lens (IOL) implantation poses risks in these cases.
  • Eyes with phacomorphic glaucoma exhibit shallow anterior chambers, convex anterior capsules, and high intralenticular pressure.

Purpose of the Study:

  • To present a safe and controlled technique for capsulorhexis in phacomorphic glaucoma.
  • To mitigate intraoperative and postoperative complications associated with cataract surgery in this patient group.

Main Methods:

  • Decompression of intumescent cataracts by anterior chamber viscoelastic injection.
  • Aspiration of liquid cortex using a 30-gauge needle to facilitate controlled capsulorhexis.

  • Subsequent safe phacoemulsification and in-the-bag IOL implantation.

    • Main Results:

    • The described technique enables a safe and controlled capsulorhexis.
    • This method addresses the challenges posed by shallow anterior chambers and high intralenticular pressure.
    • Facilitates successful phacoemulsification and in-the-bag IOL implantation.

    Conclusions:

    • This modified technique offers a safe approach for managing phacomorphic glaucoma during cataract surgery.
    • It effectively manages the anatomical challenges, reducing complication risks.
    • Enables successful visual rehabilitation through in-the-bag IOL implantation.
