Area of Science:

  • Ophthalmology
  • Surgical Innovation

Background:

  • Glaucoma and cataracts frequently coexist, necessitating combined surgical approaches.
  • Traditional combined surgeries may lead to complications like induced astigmatism and delayed healing.

Purpose of the Study:

  • To evaluate a novel combined cataract extraction and trabeculectomy procedure.
  • To assess the safety and efficacy of this combined approach in patients with coexisting glaucoma and cataracts.

Main Methods:

  • Phacoemulsification via a 3.5 mm incision with foldable hydrogel lens insertion.
  • Combined procedure performed on ten patients, followed for nine months.

Main Results:

  • Corrected visual acuity of 20/40 or better achieved in all patients without additional pathology.

  • Maximum induced astigmatism was 0.5 D; 70% showed no change or reduced astigmatism.
  • Intraocular pressures were controlled (< or = 21 mm Hg) in most patients without medication.

    • Conclusions:

    • The combined procedure maintains the benefits of small incision cataract surgery, including low astigmatism and rapid visual rehabilitation.
    • This technique may reduce wound healing stimuli, potentially lowering filtration failure rates in glaucoma patients.
