penetrating keratoplasty (PK)

Cellular therapy of the corneal stroma: Real approach or science fiction?The first human clinical trial to preliminarily evaluate the safety and efficacy of cellular therapy with mesenchymal stem cells for the corneal stroma has shown promise.
Finding alternative techniques for eyes with failed PKCornea surgeons encountering a patient with failed penetrating keratoplasty (PK) will wonder if they should repeat the PK. Although there are some exceptions to the rule, according to Donald T.H. Tan, MD, the answer is “no.”
Finding a fix for irregular astigmatism after PK Transepithelial topography-guided PRK can help correct irregular astigmatism after penetrating keratoplasty.
Infections with EK procedures risingDescemet’s stripping automated endothelial keratoplasty (DSAEK) appears to have a higher risk of postoperative fungal infections (predominantly Candida) when compared to penetrating keratoplasty (PK).
5 rules to repair DALK rupturesWorried about rupture during a deep anterior lamellar keratoplasty (DALK)? You may be overreacting. While rupture is the most common complication of DALK, its repair is not as difficult as commonly thought.
Bowman layer transplantation effective in advanced keratoconus
Bowman layer transplantation effective in advanced keratoconusIsolated Bowman layer transplantation can reduce and stabilize corneal ectasia in eyes with progressive advanced keratoconus, researchers said. “It flattens the cornea into a more normal position,” said Jack Parker, MD, a researcher at the Netherlands Institute for Innovative Ocular Surgery (NIIOS) in Rotterdam, The Netherlands. “It doesn’t give them perfect vision, but it keeps them from getting worse. It lets them to continue wearing their contact lenses.”
Performing femtosecond laser-assisted keratoplasty for keratoconusA retrospective study evaluating outcomes in patients with keratoconus found that when compared to femtosecond laser-enabled keratoplasty (FLEK), femtosecond laser deep anterior lamellar keratoplasty (FsDALK) had similar overall visual and refractive outcomes with a statistically significant lower overall graft rejection rate.
How endothelial cell loss in DSEK compares to PKAt the 10-year time point after Descemet stripping endothelial keratoplasty, the endothelial cell density is comparable to that after penetrating keratoplasty at the same time.
Why infections related to PK require intense vigilanceThe causes of infections associated with penetrating keratoplasty are evolving, but no matter what the etiology, these infections consistently require vigilance and aggressive treatment.
