The modified evulsion technique (MET) significantly reduces pterygium recurrence compared to traditional knife excision (KE). MET offers a more effective surgical option for pterygium removal, lowering the risk of regrowth.

Area of Science:

  • Ophthalmology
  • Surgical Techniques

Background:

  • Pterygium is a common eye condition that can affect vision.
  • Surgical removal is the primary treatment for symptomatic pterygium.

Purpose of the Study:

  • To compare the recurrence rates of pterygium excision using knife excision (KE) versus a modified evulsion technique (MET).

Main Methods:

  • Seventy-four pterygia were removed with KE.
  • Eighty-five pterygia were removed with MET.
  • Follow-up ranged from 6 months to 5 years (mean, 14 months).

Main Results:

  • The recurrence rate for MET was 5.88%.
  • The recurrence rate for KE was 20.27%.
  • This difference was statistically significant (p = .05).

Conclusions:

  • MET is associated with a significantly lower pterygium recurrence rate than KE.
  • MET represents a more effective surgical approach for pterygium removal.
