The use of Fibrin glue to place conjunctival graft will be as effective as suturing the graft, but will require much less operative time and will be better tolerated by the patients.

Pterygium surgery requires removal of the pterygia from cornea and conjunctiva and an additional technique to prevent recurrence which may be as high as 50%.

Suturing a conjunctival auto-graft has become one of the most popular and effective methods in preventing recurrence. However suturing requires long operative time (10-20 minutes with removal alone less than 5 minutes) and requires sutures removal after 1-2 weeks which is very inconvenient to the patient.

Using Fibrin Glue (Quixil) has been used in several places in pterygium surgery and we believe it will be as effective as suturing the graft, will use much less OR time (reduce surgery time from 40 minutes to 20-25 minutes) and will be less expensive since 2 ml glue (around 80US$) suffice for 10 cases, while one vicryl suture costs around 34 US$.
