Laser refractive surgery: technological advance and tissue response.
Photorefractive keratectomy (PRK) and laser assisted in situ keratomileusis (LASIK), using an excimer laser, are the currently popular techniques of correcting refractive errors. Since these techniques work by selective ablation of corneal stroma, the tissue healing response plays a great role in the ultimate outcome of surgery. Also, various methods of wound healing modulation can be used to a...
متن کاملCould apoptosis change the way we do PRK?
Just when we thought photorefractive keratectomy (PRK) had achieved a level of safety and predictability in correcting refractive errors in our patients, new wounding healing information regarding apoptosis (programmed cell death) surfaces to show us that the way we remove the corneal epithelium matters a great deal in how the corneal stroma responds to our treatment.1 Excimer laser manufacture...
متن کامل[Aesthesiometry of the cornea after refractive corneal surgery].
The corneal sensibility was examined with the aesthesiometer of Draeger in 41 patients after refractive corneal surgery, 31 patients after radial keratotomy, 5 after epikeratophakia, 5 after excimer laser ablation. It could be shown that after radial corneal incisions the sensibility remains normal. After epikeratophakia the corneal sensibility is asensible even 3 years after operation. The len...
متن کاملCorneal wound healing after laser vision correction.
Any trauma can trigger a cascade of responses in tissues, with the purpose of safeguarding the integrity of the organ affected by the trauma and of preventing possible damage to nearby organs. Subsequently, the body tries to restore the function of the organ affected. The introduction of the excimer laser for keratorefractive surgery has changed the treatment landscape for correcting refractive...
متن کاملEVects of amniotic membrane on epithelial wound healing and stromal remodelling after excimer laser keratectomy in rabbit cornea
Aims—To investigate if the amniotic membrane (AM) promotes epithelial migration while inhibiting stromal remodelling associated with corneal haze after excimer laser keratectomy. Methods—A wound 150 μm in depth and 6.0 mm in diameter was produced in 40 rabbits using an excimer laser. One eye was randomly chosen to be covered by the AM while the other eye served as a control. Epithelial wound he...
