A 21-year-old girl with corneal flap dissolved a week after LASIK sugery

A 21-year-old girl, a week after LASIK surgery , was found the inferior corneal flap edema, epithelium loss. Tobradex was then immediately dropped to the eye. Two days later, edema was improved and epithelium was getting smooth. Then tapered to use fluorometholone. The patient didn’t use it, which leaded to the corneal flap dissolution again. Tobradex was re-used, the corneal epithelium was gradually getting smooth again, but unfortunately the frequently using of dexamethasone leaded to steroid-induced glaucoma.

The KR-1W aberrometer system (Topcon) showed good repeatability of most internal integrated aberrometer values

A study included 26 healthy eyes of 26 subjects ranging from 20 to 50 years old showed good repeatability of most internal integrated aberrometer values with the measurement of the KR-1W aberrometer system (Topcon) which combines Shack-Hartmann wavefront aberrometry, Placido disc corneal topography and standard autorefraction. The measurement was determined for primary coma, secondary astigmatism and trefoil through 4mm and 6 mm. References: OSNsupersite NCBI
