Corneal endothelial cell loss 9 years after excimer laser keratorefractive surgery.

30 Oct 2009 OBJECTIVE: To determine the long-term changes in the corneal endothelium after laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK). METHODS: Twenty-nine eyes (16 patients) received myopic LASIK or PRK, with intended correction ... Read more...

Mitomycin C aqueous humor concentration after photorefractive keratectomy: an experimental study.

30 Aug 2009 PURPOSE: To evaluate mitomycin C (MMC) aqueous humor concentration after photorefractive keratectomy (PRK). METHODS: In this experimental study, twenty-four eyes of 12 male pigmented rabbits were divided into 4 groups and studied at the Institute of ... Read more...

Anterior segment optical coherence tomography for transepithelial phototherapeutic keratectomy in central corneal stromal scarring.

30 Aug 2009 PURPOSE: To demonstrate the use of anterior segment optical coherence tomography (ASOCT) in planning phototherapeutic keratectomy (PTK) removal of central corneal stromal scarring. METHODS: A 62-year-old male presented with central corneal scars ... Read more...

Technical information about 'Photorefractive Keratectomy'

Definition: A type of refractive surgery of the CORNEA to correct MYOPIA and ASTIGMATISM. An EXCIMER LASER is used directly on the surface of the EYE to remove some of the CORNEAL EPITHELIUM thus reshaping the anterior curvature of the cornea.
