Purpose: To report on keratoectasia after laser in situ keratomileusis (LASIK) in two eyes of two patients who had no obvious preoperative risk factors, and treatment of keratoectasia by intrastromal corneal ring segments.

Method: Clinical interventional case report.

Results: Two patients underwent LASIK in both eyes at Shinagawa LASIK center, Tokyo. Preoperative standard ophthalmological examinations demonstrated no specific risk factors of keratoectasia. However, each eye of the two patients developed keratoectasia as defined by corneal topography. Treatment for keratoectasia was performed by inserting intrastromal corneal ring segments (ICRS) in the affected eyes. In one eye, KeraRing (MEDIPHACOS, Ltd, Brazil) was inserted, and Intacs SK (Addition Technology Inc, USA) was inserted in the other.

Conclusion: Even in eyes where no risk factors for keratoectasia were found following thorough preoperative examinations, keratoectasia could develop after LASIK. ICRS could be effective for the treatment of keratoectasia after LASIK.

Keywords: keratoectasia, LASIK, intrastromal corneal ring segments
