At the Department of Ophthalmology, University Hospital in Lund, Sweden, keratoconus is the most common indication for penetrating keratoplasty. We studied 77 keratoplasties performed on keratoconic eyes between 1989-1991. Postoperative corrected visual acuity was better than or equal to 0.5 in 65 eyes (84.4%), and 30 eyes (39%) had visual acuity of 1.0. The mean postoperative astigmatism was 3.75 D with a range of 0-12.5 D. Eight patients underwent relaxing incision with satisfactory results in 6 patients. Graft rejection was observed in 6 eyes (7.8%). The most serious complication seen in our group of patients was a retrocorneal fibrous membrane that developed in one patient.

Purpose: To analyse anterior segment optical coherence tomography (AS-OCT) parameters of graft dehiscence after Descemet membrane endothelial keratoplasty (DMEK) for graft failure post penetrating keratoplasty (PK).
Methods: Retrospective evaluation of AS-OCT images of 142 dehiscences post-DMEK in 75 eyes. Dehiscences' size, depth, location, correlation with graft-host interface (GHI) override and step at GHI were assessed.

Objective: To investigate the association between preoperative aqueous humour (AqH) cytokines and mid-term endothelial cell density (ECD) following penetrating keratoplasty (PKP).
Methods: This study analysed a total of 87 eyes of which 54 underwent PKP and 33 eyes underwent cataract surgery. AqH samples were collected at the beginning of surgery.
Maintained transparency of preserved cornea after penetrating keratoplasty for fungal keratitis: A case report.

Purpose: This report presents a case of fungal keratitis treated with penetrating keratoplasty using a cryopreserved cornea, highlighting the successful maintenance of corneal transparency post infection resolution.
Observations: A 57-year-old man complaining of pain in the right eye was referred to our hospital. Although diagnosed with fungal keratitis, his corneal scraping indicated the presence of , and he was unresponsive to voriconazole, micafungin, and pimaricin treatments.

The aim of this retrospective study was to compare corneal parameters and compliance using a Pentacam HR-Scheimpflug (Pentacam HR) and a swept-source OCT Casia (Casia) in keratoconus (KC) patients post penetrating keratoplasty (PKP) and KC patients without PKP, as well as a control group. Pachymetry measurements were also analyzed using a spectral domain OCT Solix (OCT Solix), Pentacam HR, and Casia. The study included 71 patients (136 keratoconic eyes; group A), 86 eyes with KC post-PKP (group B), 50 eyes with KC without PKP (group C), and 52 control participants (104 eyes).
