title: [How can the shift of refraction due to vitreous substitutes be avoided? Posterior chamber intraocular lens for patients suffering from diabetic retinopathy].
abstract: Silicone filling of pseudophakic eyes usually results in strong unilateral hyperopia and binocularity is severely disturbed. This problem can be avoided by designing a concave posterior lens surface with the centre of curvature in the macula (Acri.Lyc 59RET®, haptics in capsular bag, body in vitreous cavity). The prospective study on 40 eyes with idiopathic macular foramen yields a mean refraction difference of 0.22 D with and without oil. The A-constant of the lens was found to be 115.7. Clinically relevant aniseikonia did not occur. The main indication is cataracts combined with diabetic retinopathy.
