Abstract: Objective: To evaluate cornea astigmatism change in pre- and post-operative pterygium excision using keratometry (differential K1 and K2) with respect to the size of pterygium and visual acuity outcome. Methods: A prospective study was conducted. There were 57 eyes that were underwent pterygium excision followed by conjunctival Autograft were selected between 1st March 2023 to 30th August 2023 using a convenient sampling technique. The participants were asked for consent form at Department of Ophthalmology, Preah Ang Duong Hospital. The effect of surgery on astigmatism was evaluated 1 to 2 weeks and 1 to 2 months after the surgery and the preoperative and the postoperative results were compared. Data analysis was done by Microsoft Excel 2016 for Window. Result: There was a significant reduction of astigmatism after pterygium surgery. The mean preoperative keratometry was 2.05 D which improved to 1.51 D at day 1 post-operatively and to 1.01 D at 1-2 weeks to 0.78D at 1-2 months. The willingness of the patients for pterygium surgery has the highest percentage in grade II pterygium, which accounted for 73.21%. The number of patients with astigmatism was seen to increase with the grade of pterygium. The mean age of the patients was 51.25 ? 23.53 years old, in which 27(54%) were male. Conclusion: The results of this study have shown an improvement in reducing the pterygium induced corneal astigmatism after surgery.
