Outcomes of Toric IOLs During Cataract Surgery in Corneal Transplant Surgery Patients
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.
