Well malignanttumor,
I am sorry to hear that it happened with you and please make sure you rule out Pinguecula and also find the attachement for detail on [
Pterygium and Pinguecula]
There are various approaches for Pterygium but none of them are effective. If the Pterygium is interfering with your vision, then typically it is removed surgically. Otherwise, it is left alone. The rate of recurrence is as high as 40, and they tend to come back bigger and faster.
Please consult an ophthamlogist for more detail on Ptetyrigium please go through the following link it has described beautifully.
