Purpose:To determine the visual and refractive outcomes of primary piggyback acrylic intraocular lens (IOL) implantation in the management of cataract in hypermetropic eyes. Methods:Nine hypermetropic eyes of eight patients (manifest spherical equivalent 4.75 to 8.37 dioptres (D)) underwent clear corneal phacoemulsification with implantation of two foldable acrylic IOLs: the posterior IOL was placed within the capsular bag and the anterior IOL in the ciliary sulcus. Patients were seen at one day, one week and six weeks following the operation, and thereafter as required. Refraction was carried out after 6 weeks. Results:There was no intraoperative complication. The spherical equivalent was reduced from a mean of 6.95D (SD 1.14) to 1.0D (SD 1.42). Postoperative best–corrected visual acuity (BCVA) was 20/30 or better in 8 eyes. Seven eyes were within 1D of intended refraction; all were within 1.7D. During the mean follow up period of 20 months (range 13 to 32 months) none of the eyes developed posterior capsule or interlenticular opacification. Conclusions:Implantation of two acrylic IOLs, within the bag and in the ciliary sulcus, appears to be a safe and efficient technique providing good refractive outcome in hypermetropic eyes. Implanting the posterior IOL in the capsular bag and the anterior IOL in the ciliary sulcus may prevent the occurrence of interlenticular opacification.
