Background: Pterygium is a fibrovascular conjunctival growth extending onto the corneal surface within the palpebral fissure. Recurrence is a common post-op complication of pterygium excision surgery, with various rates depending on the techniques used for its excision.

Objective: Comparison of conjunctival autograft versus bare sclera technique as treatment modalities for primary pterygium.

Material and Methods: This research was carried out at a tertiary-care hospital in Bahawalpur. In a prospective randomized controlled trial, a sample size of 102 eyes with primary pterygium was allocated into two equally sized groups (51 patients in each): Group A underwent pterygium excision by bare sclera method, Group B underwent pterygium excision followed by conjunctival autograft. Both groups were analyzed and compared for recurrence and complications with a mean follow-up time of 3 months.

Result: Pterygium recurrence was detected in 16 (31.37%) patients using the bare sclera technique (group A) and in 4 (7.84%) patients using the conjunctival autograft technique (group B), which reveals a statistically significant difference (p = 0.003).

Conclusion: Both surgical techniques are effective for pterygium excision; however, a statistically significant difference (p = 0.003) in pterygium recurrence between both techniques. Pterygium excision with conjunctival autograft should opt for better results in terms of recurrence as well as other complications. The bare sclera technique can be opted for preserving conjunctiva in case of glaucoma or scaring but at the expense of pterygium recurrences.
