New INTACS SK implantation in patients with post-laser in situ keratomileusis corneal ectasia.
In this case series, 2 patients with post-laser in situ keratomileusis corneal ectasia were included. Patients were treated with new intrastromal corneal ring segments, INTACS SK (severe keratoconus or steep "K") (Addition Technology, Inc, Des Plaines, IL) implantation. Two segments were inserted without any intraoperative or postoperative complications. Three months after the procedure, uncorrected visual acuity was improved in both patients from counting fingers preoperatively to 20/40 and 20/50, respectively. Best spectacle-corrected visual acuity improved from 20/40 to 20/32 and from 20/50 to 20/40. Manifest refraction improved from -8.75/-5.00 x 125 and -14.25/-6.50 x 33 preoperatively to -5.50/-2.25 x 125 and -8.25/-1.50 x 15 with an improvement in topographic findings. One year postoperatively, uncorrected visual acuity, best spectacle-corrected visual acuity, and topographic findings remained improved. In conclusion, new INTACS SK might be able to improve visual acuity in patients with post-laser in situ keratomileusis corneal ectasia.
