To investigate postoperative refraction differences between eyes with the secondary intra-capusular bag intraocular lens (IOL) implantation days after the vitrectomy and lensectomy and eyes with the primary IOL implantation using the unaffected eye’s axial length during the initial lensectomy and vitrectomy.
A retrospective study was conducted in the consecutive 28eyes of 28 patients (male: 18, female: 10, age 31 to 68 years, mean age 53.9 years) who had the axial length measurment and the secondary intra-capusular bag IOL implantation, days after reattachment of the macula following the phacoemulsification and aspiration (PEA), pars plana vitrectomy (PPV) and SF6 gas injection performed between March 2005 and August 2007. The refraction difference in each eye was studied between the actual postoperative refraction error and the error that would have been obtained if the axial length of the unaffected eye had been used.
The periods until the secondary IOL implantation ranged from 9 to 115 days (average 24.6 days). Difference between the postoperative refraction errors and the intended errors was 0.01 to 1.77D (mean 0.77D). Difference in axial length between the affected eyes and the unaffected eyes was 0.01 to 2.57mm (mean 0.39mm). If we had implanted IOLs based on the axial length of the unaffected eyes, the intended postoperative refractive errors would have differed by 0 to 3.1D (mean 0.849D) from the actual errors after the secondary IOL implantation. Difference between the IOL powers based on the axial length of the unaffected eyes and those actually used was 0 to 6D (mean 1.23D).
Postoperative refractive errors would vary when IOL powers were determined on the basis of the axial length of the unaffected eyes. We recommend the secondary intra-capsular bag IOL implantation after reattachment of the detached macula.
