Toric Intraocular Lens Implantation for Correction of Astigmatism in Cataract Patients with Corneal Ectasia
A 72-year-old man presented to our outpatient clinic with decreased visual acuity in the right eye due to cataract. The BCVA was 3/10 with −2.00 −2.00 × 60°. Automated refractometry showed −8.00 −3.25 × 58° with K1 42.25 at 62° and K2 45.5 at 152° in the right eye. Orbscan showed changes consistent with PMD (fig. ), which had been stable for the last 2 years. K values for the steep and flat axis were 47.3 D at 155° and 42.9 D at 65°, respectively. Lens power calculation was performed as described for case 1. A standard phacoemulsification was performed and a toric IOL (AcrySof SN60T5) with a spherical power of 15.5 D and a cylinder power of 3.00 D at the IOL plane was implanted. Postoperatively, the BCVA was 9/10 with −0.50 −0.50 × 73° in the right eye which remained stable in the 1-year follow-up. Corneal topography remained almost stable, with K values for the steep and flat axis of 47.1 D at 155° and 42.8 D at 65°, respectively. The patient was satisfied with the postoperative visual outcomes at the 18-month follow-up.\nAltogether, in all cases, there was a significant improvement in BCVA, as well as in refraction, which remained stable over time, as illustrated in table . Specifically, in subjective refraction, all patients achieved BCVA from 7/10 to 9/10 with up to −2.50 cyl. Corneal topography also remained stable. No IOL misalignment or other complications occurred and all patients were satisfied by the postoperative outcome.\nWritten informed consent was obtained from all patients.
