NOVEMBER/DECEMBER 2010 CATARACT & REFRACTIVE SURGERY TODAY EUROPE 23 F ull-thickness penetrating keratoplasty (PKP) has been the preferred corneal transplantation technique since the procedure was first described in 1905 by Eduard Zirm.1 Today, PKP generally results in clear corneal grafts, with a graft survival rate of up to 72% at 5 years.2 However, the procedure is frequently complicated by ...

ABSTRAGT Background/aims This paper will compare the visual outcomes of two dffierent penetrating keratoplasty (PKPI techniques in patients with keratoconus. lt is a retrospective comparative surgical case series of 116 keratoconus patients {137 eyes} who had PKP at the Cornea Eye Institute, Bevedy Hills, California, USA. Methods 56 keratoconus patients (66 eyesl underwent femtosecond laser-ena...

AIMS To create a clinically useful classification for post-keratoplasty corneas based on corneal topography. METHODS A total of 360 topographic maps obtained with the TMS-1, from 95 eyes that had undergone penetrating keratoplasty (PKP), were reviewed independently by two examiners in a masked fashion, and were categorised according to a proposed classification scheme. RESULTS A high intero...

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...

PURPOSE To evaluate the clinical outcomes of implantation of Ferrara intrastromal corneal ring segments (ICRS) in patients with astigmatism after penetrating keratoplasty (PKP). SETTING Private clinic, Belo Horizonte, Brazil. DESIGN Retrospective consecutive case series. METHODS Chart records of post-PKP patients who had ICRS implantation from May 2005 to September 2009 were retrospective...

BACKGROUND Indications for corneal transplantation in developed and developing nations differ according to the different spectrum of corneal disease in each country. OBJECTIVE The purpose of this study is to analyze the changing indications and surgical techniques for corneal transplantation over the past 20 years at a tertiary referral center in Turkey. METHODS We retrospectively reviewed ...

PURPOSE To report the outcomes of penetrating keratoplasty (PKP) in patients with macular corneal dystrophy (MCD). METHODS This retrospective case series includes consecutive patients with MCD who underwent PKP from 1986 to 2006 with at least 6 months' follow-up. Main outcome measures included best spectacle-corrected visual acuity (BSCVA), postoperative astigmatism and graft survival. RESU...

BACKGROUND Children with attention deficit-hyperactivity disorder (ADHD) often experience delays in acquiring competence completing fundamental motor skills. The effects of augmented prescriptive knowledge of performance feedback (PKP) have not been explored as a possible component solution. AIMS The purpose of this study was to test the motor learning effects of KP among boys with ADHD. ME...

Three related proteins of the plakophilin family (PKP1_3) have been identified as junctional proteins that are essential for the formation and stabilization of desmosomal cell contacts. Failure of PKP expression can have fatal effects on desmosomal adhesion, leading to abnormal tissue and organ development. Thus, loss of functional PKP 1 in humans leads to ectodermal dysplasia/skin fragility (E...
