Conditions

Pterygium. Pterygium of eye

Interventions

Intervention group: The use of cold plasma produced by the Plexr device (GMV, Italy)

For surgery, the white handpiece that produces the plasma with the lowest power (0.7 W) is used

Surgery begins by 5 to 10 spots on the upper and lower edges of the pterygium which causes the pterygium to accumulate

By using a corneal scissor, the tip of pterygium removed from the cornea and fused to the limbus by plasma spots, therefore, there is no possibility of recurrence of pterygium..
