Eligibility Criteria
Patients with pterygium not associated with other pathologies in the eye (suitable for excision) .
You may qualify if:
- Patients with pterygium not associated with other pathologies (suitable for excision).
- Nasal pterygium extended to the cornea.
You may not qualify if:
- Associated pathologies such as glaucoma, and cataract.
- Corneal opacities or irregularities, scars, dystrophy or ectasia.
- Patients who underwent previous corneal surgery (including refractive surgery)
- Pseudo-pterygium.
