Increase in ocular axial length in patients with corneal opacification.

Seventy-nine patients were studied for corneal opacification and axial myopia. They were divided into three groups. One group had bilateral clear corneas; the second had unilateral corneal scars; and the third had bilateral corneal scars. A statistically significant difference was found in the mean axial length of eyes with bilateral corneal scars when compared with age- and sex-matched controls with normal corneas (P less than 0.0001). In addition, there was a significant increase in the mean axial length of eyes with corneal scars when compared with their fellow eyes (P = 0.025).
