The study cohorts were grouped into two categories based on incision location: group 1 comprising 108 eyes from 65 children with scleral incision; group 2 comprising 110 eyes from 73 children with clear corneal incision. Cycloplegic refraction was performed at 1, 3 and 6 months postoperatively.Results The mean age in group 1 was 61±39 months and in group 2, 51±41 months. The mean postoperative astigmatism in group 1 was 1.28±0.97 D, 1.42±1.00 D and 1.38±0.98 D at 1, 3 and 6 months respectively. The change in astigmatism between 1 and 6 months was non-significant (p=0.26). The mean astigmatism in group 2 was 1.34±1.20 D, 1.13±0.88 D and 1.03±0.89 D at 1, 3 and 6 months respectively. Astigmatism in group 2 decreased significantly with time (p<0.001). The amount of astigmatism was comparable between the two groups at 1 month postsurgery (p=0.90), while it was significantly lower in the corneal incision group at 3 (p=0.03) and 6 months (p=0.01).Conclusions Postoperative astigmatism after paediatric cataract surgery by clear corneal incision was lower compared with scleral incision. However, the difference was small and clinically insignificant.
