[IOL calculations in cataract operations in children]

The rapid growth of the eye must be accounted for, when calculating the dioptric power of the IOL before cataract surgery in children. Therefore in the paper, changes in axial length of the eye, refractive power of the cornea and dioptric power of IOL for correction of aphakia in children aged 0-14 years were measured. Basing on the obtained data, the guidelines for the choice of IOL in different age of children were worked up. Between 1 and 2 years the power of the IOL should be undercorrected by 20%, at 2 to 4 years by 15% and at 4 to 8 years by 10%.
