Combined special capsular tension ring and toric IOL implantation for management of post-DALK high regular astigmatism with subluxated traumatic cataract.

ABSTRACT

We report a case of 18‑year‑old male who has undergone phacoemulsification with implantation of toric IOL (AcrySof IQ SN6AT9) after fixation of lens capsule with Cionni’s capsular tension ring (CTR) for subluxated traumatic cataract with high astigmatism after deep anterior lamellar keratoplasty (DALK). He underwent right eye DALK for advanced keratoconus four years earlier. He had history of trauma one year later with displaced clear crystalline lens into anterior chamber and graft dehiscence, which was repaired successfully. The graft survived, but patient developed cataract with subluxated lens, for which phacoemulsification with implantation of toric IOL was done. Serial topography showed regular corneal astigmatism of ‑ 5.50 diopter (K1 42.75 D @130°, K2 48.25 D @40°). At 10‑month follow‑up, the patient has BCVA 20/30 with + 0.75 DS/‑ 1.75 DC @ 110°. The capsular bag is quite stable with well‑centered IOL. Combination of Cionni’s ring with toric IOL could be a good option to manage such complex cases.
