Purpose: To review five cases of three patients with corneal ectasia after laser in situ keratomileusis, and evaluate methods and success rates of visual rehabilitation for these patients. Methods: Retrospective review of preoperative and postoperative data for each case. Results: Mean time to the development of ectasia averaged 41.6 +/– 18.0 months (range 24 to 60). Pachometry of the center of the corneal ectasia averaged 409 +/– 36.5 micron (range 366 to 472). The mean theoretical residual stromal bed thickness after laser ablation was 220 +/– 16.5 micron (range 200 to 238). Length of follow–up after the detection of the ectasia averaged 37.6 +/– 21.3 months (range 10 to 65). One eye was corrected with a RGP contact lens, one with a soft toric lens, and four with glasses. One eye required deep lamelar keratoplasty. None of the eyes lost more than one line of BCVA. Conclusions: We did not identify any patient who developed corneal ectasia without recognizable thinning of the remaining stromal bed under 250 microns. Conservative visual acuity rehabilitation, with contact lenses, gave the same BCVA as in patients with corneal transplant. When contact lens fitting is compicated, a corneal transplantation may be considered.
