Intervention model: SINGLE_GROUP
Primary purpose: SCREENING

Brief summary: The purpose of this current study is to examine the sensation of the corneal and conjunctiva sensation before and after pterygium surgeries by Cochet bonnet esthesiometer and to examine epidemiological, clinical and imaging factors the influence the sensation


Eligibility criteria: Inclusion Criteria:

* Patients that suppose to undergo pterigyum surgery

Exclusion Criteria:

* Patients with anterior segment diseases Patients that underwent anterior segment surgeries Patients with 7th nerve palsy

Primary outcomes:
measure: To sensation before and after pterygium surgeries as measured by Cochet bonnet esthesiometer
