Summary

The two-site combined phacotrabeculectomy technique offers better intraocular pressure control and reduced astigmatism compared to the one-site approach, requiring fewer medications post-surgery.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Glaucoma Management

Background:

  • Glaucoma and cataracts often require combined surgical intervention.
  • Phacotrabeculectomy is a standard procedure for managing these conditions.
  • Optimizing surgical approaches is crucial for patient outcomes.

Purpose of the Study:

  • To compare the efficacy and safety of one-site versus two-site combined phacotrabeculectomy.
  • To evaluate intraocular pressure (IOP) reduction and visual acuity.
  • To assess postoperative complications and medication requirements.

Main Methods:

  • Randomized comparison of one-site and two-site combined phacotrabeculectomy with intraocular lens implantation.
  • Thirty-four patients (41 eyes) were assigned to either the one-site (22 eyes) or two-site (19 eyes) procedure.
  • Procedures involved standard superior trabeculectomy or clear cornea phacoemulsification with separate trabeculectomy.

Main Results:

  • Both techniques achieved significant IOP reduction and similar best-corrected visual acuity (BCVA) improvements.
  • The two-site group showed a trend towards less induced astigmatism (P=0.058).
  • The one-site group required significantly more antiglaucoma medications (P=0.03) post-surgery.

Conclusions:

  • Both one-site and two-site phacotrabeculectomy are effective in reducing IOP and improving BCVA.
  • The two-site approach demonstrated advantages in reduced induced astigmatism and lower medication dependency.
  • The two-site technique may offer superior postoperative IOP control and patient comfort.
