RUIZ RODRIGUEZ, Yanele et al. Piggy Back in the treatment of the hypermetropic refractive surprise. Rev Cubana Oftalmol [online]. 2011, vol.24, n.1, pp. 161-169. ISSN 0864-2176.
The Piggy Back technique or the implant of two lens is proposed mainly when it is necessary the correction of more than 30 diopters in crystalline lens surgery. The lens above 34 diopters are not available in the market at the same time that the lens of more than 30 diopters are not recommendable due to the spherical aberration producing an optical surface with a very small curvature.radius. This is the case of a patient aged 47 with backgrounds of previous corneal refractive surgery in both eyes, but carrier of a high hypermetropia in his right eye and thus, a hypermetropic anisometropia leading to as therapeutical option, to carried out the crystalline extraction of right eye and the implant of both lens: one in capsular sac and other in ciliary sulcus. The correction of the refractive defect of this patient was achieved without complications.
