Torquetti L, et al. - In this multicentric nonrandomized study, researchers assessed clinical outcomes in the eyes of patients with keratoconus who had implantation of a new 320°-arc length Ferrara intrastromal corneal ring segment (320-ICRS). In 138 eyes of 130 patients with keratoconus, a new 320-ICRS was placed. Both preoperatively and at the final follow-up visit after the procedure, evaluation was carried out for uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), keratometry, corneal volume, asphericity, lines of vision gain/loss, and vectorial analysis. An increase was observed in the mean corneal volume, from 56.2 ± 4.28 mm³preoperatively to 57.6 ± 4.74 postoperatively. In addition, an attenuation in mean Km, from 53.3 ± 5.5 D preoperatively to 47.8 ± 4.6 D postoperatively, was also evident. A statistically significant change in UDVA, CDVA, and topographic astigmatism was seen. Overall, the corneal shape was modified to a more physiologic, aspheric shape by the 320-ICRS, thereby improving visual acuity in an efficient and safe manner in these patients.
