OBJECTIVE
To report a case of corneal hydrops with perforation in a patient with ectasia after undergoing laser in situ keratomileusis (LASIK).
METHODS
An observational study with clinical, optical coherence tomographic, and histopathologic findings.
RESULTS
A 41-year-old woman had an acute onset of blurry vision, pain, photophobia, tearing, and foreign body sensation in the right eye 10 years after undergoing unilateral LASIK in Jordan. According to her, the surgeon elected not to operate on the left eye because of a "corneal abnormality." On slit-lamp examination, a tear in Descemet membrane with a stromal cleft extending to the overlying LASIK flap interface was noted. The flap was partially dehisced by a diffuse channel of aqueous humor draining from the cleft and streaming out the temporal flap edge. When leakage failed to stop after 2 weeks of treatment with a bandage contact lens, the patient underwent penetrating keratoplasty. Histopathological examination of the host button showed a fluid-filled cleft connecting the flap interface. Slit-lamp examination and corneal topography of the contralateral left eye were consistent with keratoconus.
CONCLUSIONS
Corneal hydrops with perforation in the setting of post-LASIK ectasia is extremely rare and may be associated with flap dehiscence requiring penetrating keratoplasty.
