Abstract

Purpose: To evaluate keratometry readings and corneal astigmatic changes following pterygium excision with conjunctivalautograft transplantation.Patients and methods: An observational study performed on 107 patients withprimary pterygium attending at the department of ophthalmology; Rohilkhand medical college & Hospital Bareilly fulfilling the inclusion criteria.Results: It was observed in our study that Power of astigmatism(D) preoperatively was 3.12±1.97 D while postoperatively it was 1.70±1.27 and at first follow up it was 1.43±1.09. On comparing the three values we observed that the pre operative values were significantly more than postoperative and first follow up readings and also the postoperative values were significantly more than the first follow up and average keratometry values preoperatively was 45.51±2.10 while after removal it was 44.99±1.99 and at first follow up it was 44.25±2.22. on comparing the three values we observed that the pre operative values were significantly more than postoperative and first follow up readings and also the postoperative values were significantly more than the first follow up. Conclusion: The present study verifies that there is reduction in astigmatism after successful removal of pterygium and also improved the VA either by decrease in astigmatism or by removal of the pterygium from the pupillary axis.
