Abstract :

Aim: To study the effect of Pterygium excision on Astigmatism induced by Pterygium. Materials and Methods: This is a Prospective interventional study conducted at the department of Ophthalmology of Bhaskar General hospital which is attached to Bhaskar Medical College. Study was done during the June 2017 to May 2018. 100 patient of Primary Pterygium which induce more than 1.5 D Cyl Astigmatism were included in the study. Patients with recurrent Pterygium, Pseudo–Pterygium and those who were having ocular disorders like Herpetic keratitis were excluded from the study. All cases were examined by an experienced Ophthalmologist. Pre operativeAstigmatism was measured by Auto refractometer. Basic surgical profile investigations were done. Cases were posted for surgical excision of Pterygium leaving bare sclera or Excision with Conjunctivallimbalautograft harvested from supero temporal Limbus sutured by 10 ‘0 Nylon or attached by Glue to bare area from where Pterygium was excised. Post operative Astigmatism was recorded and reduction in Astigmatism was obtained by substractingPost operative astigmatism from pre operative astigmatism. Results: The pre operative Astigmatism ie mean cylinder with SD was 4.56D Cyl + 1.81 was reduced to Mean Cyl of 1.96D Cyl with SD of 1.06. P value was >0.05 which is statistically significant. Conclusion:Pterygium induced astigmatism and its surgical removal reduces astigmatism to statistical significant level.
