Secondary piggyback with PMMA IOL for the correction of refractive surprise after phacoemulsification. Long-term results of 20 cases Piggyback secundário com LIO de PMMA para correção de surpresa refracional pós-facoemulsificação. Resultados a longo prazo de 20 casos

Purpose: To evaluate long-term results of the secondary piggyback technique used for the correction of undesired ametropia after phacoemulsification. Methods: Retrospective study comprising of 20 eyes (19 patients). The IOL used was a single-piece PMMA with an overall length of 12.5mm, a 5x6mm oval thin-edged optic with a 10-degree haptic angulation. The same technique was used in all cases, consisting of a scleral-corneal tunnel with a 5mm opening, through which the secondary intraocular lens was implanted into the ciliary sulcus. Results: The undesired ametropia was corrected in all cases. No complications were observed during or after the secondary piggyback procedure. Conclusion: The use of a single-piece PMMA IOL proved to be safe and effective in secondary piggyback for the correction of refractive surprises after phacoemulsification.
