Excimer Laser-Assisted Deep Anterior Lamellar Keratoplasty Versus Penetrating Keratoplasty for Patients With Keratoconus: A Retrospective Analysis From the Homburg Keratoconus Center.

Purpose: To evaluate the outcome of excimer laser-assisted deep anterior lamellar keratoplasty (Exc-DALK) and penetrating keratoplasty (Exc-PKP) for keratoconus (KC).

Methods: We included 123 eyes and compared the outcome of 30 eyes undergoing big-bubble Exc-DALK after stromal debulking (G1) against a matched group of 83 eyes undergoing Exc-PKP (G2) in our department. G2 was created after performing a pseudorandom stratified bootstrapping of our PKP database starting with 2802 surgeries with removal of any bias.

Autologous Contralateral and Ipsilateral Rotational Penetrating Keratoplasty - A Case Series and Mini-Review.

Corneal stromal opacities can severely impact visual acuity if they are located in the visual axis. Homologous penetrating keratoplasty (HPK) is usually the preferred surgical option in such clinical circumstances. However, autologous penetrating keratoplasty (APK) could be an immunologically safer alternative.

[Bacterial keratitis : Clinical aspects, pathogens and treatment].

Bacterial infections are by far the most frequent cause of infectious keratitis in high-income countries. The clinical appearance can vary widely depending on the type and species of bacteria, ranging from small superficial infiltrates to necrotizing forms. The numerous classes of available antibiotics render the treatment scope diverse and complex, especially before the pathogen has been specified and the sensitivity to antibiotics has been tested.
