Most surgical procedures involving the anterior segment of the eye disrupt the normal
organization of corneal innervation. Since denervation of the cornea results in impaired …

For more than 15 years, the excimer laser has been used as a surgical instrument on the
cornea. Photorefractive keratectomy (PRK) followed radial keratotomy as researchers …

PURPOSE: To evaluate and compare tear secretion and tear film instability following
photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK). SETTING …

Purpose: To evaluate the effect of photorefractive keratectomy (PRK) and laser in situ
keratomileusis (LASIK) on corneal sensation. Setting: Eye Institute, Medical School of the …

PURPOSE:: To evaluate the change in corneal sensitivity following laser in situ
keratomileusis.(LASIK). SETTING:: Department of Ophthalmology, Maryknoll Hospital …

PURPOSE: To compare the effects of photorefractive keratectomy (PRK) and laser in situ
keratomileusis (LASIK) on corneal sensation. SETTING: Ohshima Hospital of …

ABSTRACT BACKGROUND: Photorefractive keratectomy affects corneal innervation in a
new, and drastic, way. This inevitably results in a significant loss of corneal sensitivity. This …

The cornea is densely innervated with free nerve endings to provide a high level of
sensitivity to foreign bodies or noxious substances. They also provide trophic support to the …

The cornea is the most richly innervated surface tissue of the body. It receives its
predominantly sensory nerves from ciliary branches of the ophthalmic division of the …

PURPOSE: To evaluate the recovery of corneal sensitivity after laser-assisted subepithelial
keratectomy (LASEK) for myopia. SETTING: Department of Ophthalmology, Eye and ENT …
