Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| To sensation before and after pterygium surgeries as measured by Cochet bonnet esthesiometer | Before surgery compare to one week+ one month+three months after surgery | The change in sensation in the cornea and conjunctiva after pterygium surgery as measured by Cochet bonnet esthesiometer |
Secondary
