Corneal Densitometry as a Tool to Measure Epithelial Ingrowth After Laser In Situ Keratomileusis.

چکیده
PURPOSE This study evaluates the correlation between corneal densitometry and epithelial ingrowth (EI) after laser in situ keratomileusis (LASIK). METHODS Corneal densitometry of 3 patients who developed EI after LASIK was measured with the Oculus Pentacam. Corneal densitometry readings of each patient were obtained preoperatively and postoperatively after ingrowth was discovered. Densitometry was recorded at the central nest of opacity and at the leading edges of EI. RESULTS For all patients, the most severe stages of EI observed on slit-lamp photographs correlated with the highest densitometry readings, with peak densitometry ranging from 73.3 to 95.1. These values were much higher than preoperative densitometry readings, which ranged from 21.8 to 27.2. In 2 cases, the Pentacam densitometry map revealed progression of EI toward the visual axis that was only faintly detectable or not detectable at all on the corresponding slit-lamp photographs. CONCLUSIONS Corneal densitometry seems to be an objective measure of the severity and progression of EI after LASIK.

متن کاملUse of a hydrogel sealant in epithelial ingrowth removal after laser in situ keratomileusis.
UNLABELLED We describe 2 cases in which clinically significant epithelial ingrowth was removed by debridement and followed by the use of a hydrogel sealant (Resure) to seal the flap edge. In both cases, the epithelial ingrowth was seen after otherwise uneventful laser in situ keratomileusis retreatment. The visual outcomes were good with no recrudescence of interface epithelium.

Neodymium: Yttrium-Aluminum-Garnet (Nd-YAG) laser treatment of epithelial ingrowth was found promising with high success rates in cases of primary post-LASIK epithelial ingrowth. However, the application range of this procedure is not well-known. For the first time, the authors report the outcome of a patient treated with Nd-YAG laser for multiple recurrences of post-laser in situ keratomileusi...
