intraocular lens power calculation after keratorefractive surgery

purpose: to determine corneal power for intraocular lens (iol) power calculation in eyes with previous keratorefractive surgery. methods: in 13 eyes of 9 patients with previous keratorefractive surgery undergoing phacoemulcification, iol power was calculated using the clinical history method (chm) in one case, manual keratometry (mkr) in 2, simk in 3, and flattest k (topographically derived) in...

Estimation 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...

Corneal 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 ...

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...

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

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 to emmetropia. Central endothelial photographs were taken before and 9 years after surgery and were analyzed by the same masked investigator after ...
