PURPOSE To evaluate the efficacy of excimer laser in situ keratomileusis (LASIK) in the treatment of refractive errors after penetrating keratoplasty. METHODS Eight eyes underwent LASIK after a mean 71 months (SD 60) following the initial penetrating keratoplasty. A full ophthalmic assessment was performed before LASIK and at 1 week, 1, 3, 6, and 12 months after surgery. Mean follow-up was 8....

BACKGROUND The purpose of this report is to describe the initial outcomes of femtosecond laser-assisted penetrating keratoplasty. METHODS This retrospective surgical case series consisted of 10 eyes from 10 patients undergoing penetrating keratoplasty at a tertiary center. Femtosecond laser was used to perform a zig-square incision on the donor cornea with matched dimensions on the recipient ...

Keratoconus (KC) is a bilateral sight threatening disease that affects the cornea. It consists of gradual steepening central cornea associated with irregular astigmatism and may lead to corneal opacities. In some cases, keratoplasty needed restore vision. Even though it not frequent, recurrence KC in donor tissue has been described, usually bilateral. Recurrence respond problems related graft o...

Purpose. To evaluate the visual and refractive outcomes after small incision lenticule extraction (SMILE) for treating myopia and myopic astigmatism after penetrating keratoplasty (PKP). Design. Case-series. Methods. Ten eyes of 10 patients with previous PKP and residual myopic astigmatism for whom pentacam imaging and thickness measurements were acceptable for laser vision correction. Manifest...

BACKGROUND To report a patient with penetrating keratoplasty (PKP) graft endothelial failure implanted with toric intraocular lens (IOL) who was treated with Descemet stripping endothelial keratoplasty (DSAEK). CASE PRESENTATION A 40 year old male patient implanted with toric intraocular lens for the treatment of post PKP astigmatism, presented for the treatment of graft endothelial failure'....

DEEP ANTERIOR LAMELLAR KERATOPLASTY: A NEW MANUAL TECHNIQUE Rama et al report visual outcomes in 288 eyes undergoing deep anterior lamellar keratoplasty with a new manual dissection technique. A deep corneal incision was obtained with a calibrated diamond knife to reach a pre-Descemet plane. At the 2-year postoperative follow-up, the mean logarithm of the minimum angle of resolution best specta...

background: astigmatism is the leading complication in visual recovery after penetrating keratoplasty (pkp) and deep anterior lamellar keratoplasty (dalk); in this study, we evaluated the outcome of femtosecond laser arcuate keratotomy (flak) after dalk and pkp in iranian keratoconic patients. materials and methods: in this prospective interventional case series, refractive and keratometric pre...

PURPOSE To evaluate the safety and efficacy of customized transepithelial photorefractive keratectomy (PRK) for the correction of iatrogenic ametropia after penetrating keratoplasty (PKP) or deep lamellar keratoplasty. SETTING Eye Clinic, Department of Neurological and Visual Sciences, University of Verona, Verona, Italy. METHODS This study comprised 9 patients who had irregular astigmatism...
