Pterygium Removal Surgery
Is the abnormal growth of the conjunctiva invading the cornea. Geographical disease is very common in the equatorial zone, notably related to solar radiation. It can be prevented by using sunglasses, but once established the only definitive treatment is surgical resection.
It is disturbing that in the course of time, after the huge scientific and technical development achieved in recent years and many surgical techniques, the pterygium is still a problem in ophthalmic practice target. This is a purely surgical treatment condition. All tested therapeutic attempts have failed because it is difficult to destroy completely and exclusively the subconjunctival connective tissue mass that constitutes the real body of the pterygium.
Recurrence rate is between 20 and 40% with conventional techniques. Repeated surgical procedures on the cornea that try to eliminate this membranous fold conjunctival often cause loss of tissue and scars shrink, and become major damage.
Free conjunctival plasty is a procedure used successfully in recent years. Involves thorough cleaning of the area of pterygium and normal conjunctiva transplantation to the surgical area, where it was dissected.
Conjunctival free plasty is effective and safe procedure that is basically used in the recurrent pterygium: primary performed within the guarantees of success, as the anterior segment structures remain intact morphology.
The recurrence rate with free plasty conjunctival and upper limb reduced to 0.5-1% the possibility of recurrence.
