Corneal ectasia after photorefractive keratectomy.
Two patients developed corneal ectasia after photorefractive keratectomy (PRK). Case 1 had evidence of early keratoconus preoperatively, with manifest refractions of -4.00 +2.50 x 160 (20/20) in the right eye and -7.00 +3.00 x 180 (20/30) in the left eye; thin corneas (472 microm and 441 microm, respectively); and inferior paracentral steepening in the right eye and central steepening in the le...
متن کاملCorneal epithelial recovery following photorefractive keratectomy.
AIMS To further understand the morphological and functional recovery of corneal epithelium following excimer laser photorefractive keratectomy (PRK). METHODS The right eyes (group 1) of 15 male, New Zealand white rabbits weighing 2-3 kg underwent PRK. The left eye of each rabbit (group 2) underwent simple mechanical de-epithelialisation and were examined as treated controls. Both eyes of anot...
متن کاملEpithelial cell adhesion and haze after photorefractive keratectomy.
orneal haze is the most serious complication of photorefractive keratectomy (PRK) and has been attributed to normal healing processes. 1-3 The prediction of which patients are likely to develop haze is of the utmost importance in the evaluation of patients for PRK. We noted that while removing the epithelium prior to corneal ablation, three distinct types of cornea can be appreciated: 1) normal...
متن کاملInfluence of patient age on refraction and corneal haze after photorefractive keratectomy.
AIMS/BACKGROUND Since wound healing processes are known to be more rapid in those who are young, it was decided to examine the effect of patient age on refractive outcome of photorefractive keratectomy (PRK). METHODS The records of 599 eyes that had undergone PRK were studied retrospectively. The eyes were categorised by baseline myopia and patient age. Spherical equivalent and corneal haze w...
متن کاملCorneal Regeneration After Photorefractive Keratectomy: A Review.
Photorefractive keratectomy (PRK) remodels corneal stroma to compensate refractive errors. The removal of epithelium and the ablation of stroma provoke the disruption of corneal nerves and a release of several peptides from tears, epithelium, stroma and nerves. A myriad of cytokines, growth factors, and matrix metalloproteases participate in the process of corneal wound healing. Their balance w...
