Management of Post-LASIK Corneal Ectasia With Intacs Inserts: One-Year Results

OBJECTIVE To prospectively study the effects of the use of Intacs microthin prescription inserts (Addition Technology Inc, Fremont, Calif) for the postoperative management of corneal ectasia resulting from laser in situ keratomileusis (LASIK). METHODS In this prospective nonrandomized clinical trial, 10 eyes of 7 patients with post-LASIK corneal ectasia (2 men and 5 women) aged 33 to 46 years (mean± SD, 40.67 ± 5.99 years) were included. The follow-up ranged from 6 to 24 months (mean ± SD, 15.0 ± 6.5 months). Two Intacs segments of thickness depending on the residual refraction of the patients were inserted in each eye. MAIN OUTCOME MEASURES Uncorrected visual acuity, best spectacle-corrected visual acuity, refractive outcome, and topographic findings after Intacs implantation. RESULTS Intacs were successfully implanted in all eyes. Spherical equivalent error was statistically significantly reduced after Intacs implantation (pre-Intacs, mean ± SD: −4.81 ± 3.24 Diopters (D) (range, −13.75 to −2.50 D) to −0.96 ± 2.93 D (range, −8.75 to 2.50 D) (P
