Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
With this, the objective is to evaluate the benefits of a new technique for pterygium surgery with respect to postoperative patient comfort, surgery time, cost and recurrence rate.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Sutures
After pterygium removal the conjunctival graft to cover bare sclera will be secured with interrupted 8.0 polyglactin sutures.
Sutures
* Pterygium dissected off, corneal bed burred smooth and autograft harvested as per usual technique.
* Conjunctiva undermined at the recipient site.
* Graft is slid into place The graft is secured to host conjunctiva using 7 interrupted sutures
Cautery
After pterygium removal the conjunctival graft to cover bare sclera will be secured with bipolar electrocautery, power set at 25 until whitening of tissue observed.
Cautery
* Pterygium dissected off, corneal bed burred smooth and autograft harvested as per usual technique.
* Conjunctiva undermined at the recipient site.
* Relaxing incisions placed at the corners of the recipient site.
* Graft is slid into place
* Graft / host interface is gently dried with a Qtip
* Bipolar cautery is applied after grasping the graft and host conjunctiva gently between cautery forceps.
* Power setting: 25.
* Duration of cautery: 4 -5 seconds; the tissue should whiten and contract as desiccation and coagulation take place. Some charring may occur.
* Counter traction is applied to the conjunctiva as the cautery forceps are gently teased off
* Cautery is applied at the 4 apices of the graft then in between these points.
