Phacoemulsification-aspiration with intraocular lens implantation significantly lowers intraocular pressure in primary open-angle glaucoma patients long-term. This surgical approach offers a sustained reduction in eye pressure for glaucoma management.

Area of Science:

  • Ophthalmology
  • Glaucoma Research
  • Surgical Innovation

Context:

  • Primary open-angle glaucoma (POAG) is a leading cause of irreversible blindness.
  • Managing intraocular pressure (IOP) is crucial for POAG progression.
  • Phacoemulsification-aspiration with intraocular lens implantation (PEA + IOL) is a common ophthalmic procedure.

Purpose:

  • To evaluate the long-term effect of PEA + IOL on IOP in POAG patients.
  • To compare IOP changes in POAG eyes versus control eyes after surgery.
  • To determine if PEA + IOL can reduce the need for glaucoma medications.

Summary:

  • A study involving 40 POAG eyes and 53 control eyes assessed postoperative IOP changes over an average of 34 months.
  • Significant IOP reduction was observed in all groups, sustained for up to 3 years post-surgery.

  • The magnitude of IOP decrease correlated with preoperative IOP levels in POAG patients, with greater reductions in those with higher initial pressures.

    • Impact:

    • PEA + IOL surgery can lead to a sustained decrease in intraocular pressure in patients with primary open-angle glaucoma.
    • The procedure demonstrates potential as an effective intervention for IOP management in POAG.
    • Findings suggest that PEA + IOL may offer a valuable surgical option for controlling IOP in POAG, potentially reducing medication dependence.
