Abstract

Methods:A prospective interventional comparative study was conducted on 85 patients with unilateral nasal/temporal pterygium.Pre and 6 weeks post operative visual acuity,keratometric astigmatism and higher order aberration (HOA) were compared.Patients were divided into two groups Group A (1mm, 2mm) &Group B (3mm, 4mm) based on size of pterygium.

Results:The mean visual acuity was 0.12±0.23 improved to 0.06±0.16 post operatively.Statistically significant decrease in mean corneal astigmatism and HOA from (1.77±1.02D) (0.93±0.60) to post operatively (0.61±0.38 D)(0.43±0.23) (p value <0.01).Mean pre-operative and post-operative astigmatism difference,HOA difference between group A (0.73±0.30D),(0.31±0.05)& group B (2.23±0.61D) (0.98±0.54)showed statistically significant decrease in group A (p value <0.01) Conclusion:Successful and early surgical excision of pterygium can lead to improvement in corneal topographic changes with lesser residual post-operative corneal astigmatism and HOA.
