Effect of hinge position on corneal sensation and dry eye after laser in situ keratomileusis using a femtosecond laser

Abstract

Mild dry-eye disease was present early after myopic LASIK with the IntraLase laser. Hinge position had no effect on central corneal sensation or dry-eye disease.

Comparison of dry-eye disease severity after laser in situ keratomileusis and laser-assisted subepithelial keratectomy

“…Dry-eye disease or tear dysfunction is the most common source of morbidity after refractive laser procedures, [1][2][3][4] affecting approximately 50% of laser in situ keratomileusis (LASIK) (120 mm flap) patients at 1 week, 40% at 1 month, and 20% to 40% at 6 months.…”

Dry eyes and corneal sensation after laser in situ keratomileusis with femtosecond laser flap creation

“…11 However, subsequent studies have not established an association between corneal sensation and hinge position with a microkeratome 12 or a femtosecond laser. 13 Hinge angle and flap thickness can also affect corneal sensation and dry-eye disease.

Evaluation of transcutaneous electrical simulation to improve recovery from corneal hypoesthesia after LASIK

“…Better recovery at this point may be due to clockwise centripetal direction of sub-basal nerve plexus, which have a whorl pattern migration such as that already shown by in vivo confocal microscopy [27]. In all patients, we used a superiorly hinged LASIK flap; according to some studies, this may increase the corneal denervation, but the results are conflicting [28][29][30][31].…”
