This study introduces microkeratome-assisted phacoemulsification for cataract surgery in patients with ocular surface disease. The technique safely improved visual acuity in a patient with a history of trachoma.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Corneal Surgery

Background:

  • Ocular surface disease presents challenges for standard cataract surgery.
  • Phacoemulsification with intraocular lens (IOL) insertion requires clear visualization of the anterior chamber.
  • Previous surgical history, such as trachoma, can compromise ocular surface health.

Purpose of the Study:

  • To report a novel surgical technique combining microkeratome flap creation with phacoemulsification and IOL insertion.
  • To evaluate the safety and efficacy of this combined approach in a patient with ocular surface disease.

Main Methods:

  • A 130-micrometer corneal flap was created using a microkeratome in a 72-year-old female patient with a history of childhood trachoma.
  • Phacoemulsification and IOL insertion were performed after lifting the microkeratome flap.

  • The corneal flap was repositioned without sutures post-operatively.

    • Main Results:

    • The microkeratome flap provided a clear view of the anterior chamber during surgery.
    • No intraoperative or postoperative complications related to the corneal flap were observed.
    • Postoperative visual acuity improved from hand motion to 20/200.

    Conclusions:

    • Microkeratome-assisted phacoemulsification is a safe and effective technique for managing cataracts in patients with ocular surface disease.
    • This approach facilitates clear visualization, potentially reducing surgical complications.
    • Further studies are warranted to assess the broader applicability of this technique.
