Aim: This study aims to determine the effect of pterygium excision on the degree of corneal induced astigmatism and visual acuity. Patients and Methods: This was a prospective interventional study conducted between September 2012 and June 2013. Consecutive patients with pterygium who met the inclusion criteria were recruited into the study. They had a basic eye examination, and those with existing comorbidity were excluded. Selected patients had pterygium excision using the bare sclera technique with intraoperative application of Mitomycin C. Detailed pre- and post-operative evaluation and refraction was done. Results: There were 45 eyes of 33 patients aged 28–75 years. The mean age was 56.12 + 12.38 years. Six eyes had Grade I, 29 eyes had Grade II and 10 eyes had Grade III pterygium. The mean value for preoperative astigmatism was 2.12 ± 1.09 diopter cylinder (DC) while that for postoperative astigmatism was 0.72 ± 0.50 DC (P = 0.000). Surgery was associated with statistically significant increase in postoperative visual acuity. (P = 0.000).Conclusion: This study has shown that the degree of pterygium-induced astigmatism reduces significantly following surgical excision. Pterygium excision was associated with improvement in visual acuity.
