dry eye following keratorefractive surgery
purpose: to compare tear secretion values following lasik (laser in situ keratomileusis) and photorefractive keratectomy (prk). methods: patients referred to aban eye clinic (isfahan, iran) for refractive surgery were randomly assigned to lasik or prk. exclusion criteria were contraindications for refractive surgery, usage of topical ocular drugs, dry eye and reoperation. schirmer test was perf...
متن کاملCalculations of actual corneal astigmatism using total corneal refractive power before and after myopic keratorefractive surgery
PURPOSE To calculate actual corneal astigmatism using the total corneal refractive astigmatism for the 4-mm apex zone of the Pentacam (TCRP4astig) and keratometric astigmatism (Kastig) before and after photorefractive keratectomy or laser in situ keratomileusis. METHODS Uncomplicated 56 eyes after more than 6 months from the surgery were recruited by chart review. Various corneal astigmatisms...
متن کاملEstimation of true corneal power after keratorefractive surgery in eyes requiring cataract surgery: BESSt formula.
PURPOSE To describe a new formula, BESSt, to estimate true corneal power after keratorefractive surgery in eyes requiring cataract surgery. SETTING Moorfields Eye Hospital, London, United Kingdom. METHODS The BESSt formula, based on the Gaussian optics formula, was developed using data from 143 eyes that had keratorefractive surgery. The formula takes into account anterior and posterior cor...
متن کاملCorneal Wound Healing After Keratorefractive Procedures
Bowman’s layer is composed of 22nm heterotypical type I collagen fibrils, which are randomly orientated (mean direction 45o to the corneal surface). Immediately beneath Bowman’s membrane, the cornea is arranged such that there are about 300 lamellae centrally and 500 lamellae peripherally. Each is composed of uniformly paralleldirected, 25nm heterotypical type I collagen fibrils with flattened ...
متن کاملGlaucoma following Corneal Transplant Surgery
Post-PK glaucoma is an important cause for irreversible visual loss and graft failure after penetrating keratoplasty. The etiology for this disorder is multifactorial and with the use of new diagnostic equipment it is now possible to elucidate the exact pathophysiology of this condition. A clear understanding of the various mechanisms which operate during different time frames following keratop...
