To report applications of optical coherence tomography (OCT) in the management of LASIK–related problems.
Five patients referred to an academic refractive surgery practice for LASIK–related problems were studied with clinical examination, ultrasound pachymetry, Placido–ring, slit–scanning corneal topography (Orbscan II) and high–speed corneal OCT.
OCT provided thickness measurements of the cornea, flap and posterior stromal bed in cases of regression, keratectasia, decentered ablation and flap complication. Locations of tissue loss and flap interface planes were identified in a recut enhancement complication. The information was useful in determining whether further laser ablation was safe, confirming keratectasia and managing complications.
High–speed OCT is uniquely able to provide non–contact imaging and measurement of LASIK anatomy. It is useful for monitoring LASIK results and evaluation of complications.
