The differences between S and P eye were measured and examined after randomly indexing the left or right eye as primary and secondary, as well as anterior chamber depth ACD, and lens thickness LT. With the Castrop formula for all P and S eyes, the refraction was predicted, using both the P and S eye biometry for the lens power calculation. Conclusion: Despite the closeness of both eyes, an intraocular lens power estimation with fellow eye biometry could produce different results for the lens strength and eventually for the predicted refraction. In 10% of cases, the lens power derived from the S eye deviates by 2 dpt or more, resulting in a refraction deviation of 1. 36 dpt or more.
