Management of subluxated cataracts is challenging, especially in cases with more than 5 clock hours of subluxation. Capsular bag stabilising devices are of utmost importance in these cases. We report two cases of post-traumatic lens subluxation of more than 6 clock hours, in which the bag was stabilised intraoperatively using two capsular tension rings (CTRs) placed diametrically opposite to each other, in place of the conventional Cionni ring. Slow phacoemulsification was done followed by intraocular lens (IOL) implantation. Postoperatively, the IOLs were found to be well centred. Also, the use of two CTRs maintains the shape of the capsular bag and prevents lens epithelial cell migration and capsular cocontraction.
