Piggyback silicone intraocular lenses of opposite power.

A patient with high myopia and astigmatism had cataract extraction with implantation of 2 silicone intraocular lenses (IOLs) of opposite power (ie, 1 plus and 1 minus). A Staar AA4203TL toric IOL (+9.50 diopters [D]/3.50 D) and a Staar AQ5010V additive lens (-3.00 D) were used to correct both the astigmatism and the high myopia. The use of the 2 lenses was necessary because the toric IOL was not available in low dioptric powers. A crystalline interpseudophakos deposit developed after 1 week and resolved after 4 weeks. Three months postoperatively, the patient had an uncorrected visual acuity of 20/25.
