This study analyzes the results of the use of toric intraocular lenses (IOLs) during cataract surgery in patients who have had corneal transplants (CTS).

A retrospective chart review was performed of all patients who had CTS prior to the insertion of a toric IOL during subsequent cataract surgery. We analyzed pre- and postoperative vision and pre- and postoperative astigmatism, surgical complications and long-term graft clarity.

There were 17 patients who qualified. The average age at time of CTS was 48.2 years, ranging from 6 months to 76 years. Indications for CTS were 12 for keratoconus, 2 for lattice dystrophy, 1 for Fuchs dystrophy, 1 scar, and 1 for congenital hereditary endothelial dystrophy (CHED). The average time interval between CTS and the toric IOL is 5.53 years, ranging from 4 months to 19 years. The preoperative visual acuity, prior to cataract surgery, ranged from 20/800 to 20/50 (0.03-0.4). The average preoperative astigmatism was 5.53+/-2.76, ranging from 1.75 to 10.75. Postoperative visual acuities ranged from  20/150 to 20/20 (0.13-0.80). The average astigmatism after the cataract surgery was 2.35 +/- 1.48 ranging from 0 to 5.00. There were no intraoperaitve or postoperative complications.

In patients who present with cataracts several years after their corneal transplant, toric IOLs can lead to better visual results and less astigmatism.
