Abstract | BACKGROUND: PURPOSE: METHODS: Four eyes of keratoconus patents were treated with Zyoptix wavefront-guided LASEK for correction of residual myopia and astigmatism after insertion of INTACS. The refraction after insertion of INTACS was stable at least six months before the Zyoptix- LASEK. The mean pre-INTACS refraction was myopia of -2.37 D (range 0 to - 5.00 D) and astigmatism of -3.93 D (range -1.00 to -7.5 D). The mean refraction prior to Zyoptix- LASEK was myopia of -0.2 D and astigmatism of -2.71 D. The mean follow-up period after the Zyoptix LASEK was 8 months. RESULTS: Initially, prior to both surgeries, the mean uncorrected visual acuity was 6/240 (range count-fingers to 6/60) and at the final postoperative visit 6/12 (range 6/10 to 6/ 18). The preoperative mean best spectacle corrected visual acuity was 6/15 (range 6/10 to 6/24) and at the final postoperative follow-up visit 6/9 (range 6/8.5 to 6/12). CONCLUSION: Zyoptix wavefront-guided LASEK for correction of residual myopia and astigmatism in keratoconus patients after INTACS insertion and stable refraction provided excellent visual outcome, with no loss of visual acuity and no complications.
