: Aniridia-associated keratopathy (AAK) is a potentially vision-threatening pathology in congenital aniridia, for which both the underlying etiopathogenesis and effective treatment remain unclear. :This prospective study was conducted to assess and compare the short-term outcome after superficial keratectomy (SK) alone or in a combination with an amniotic membrane transplantation (AMT). Here, 76 eyes were enrolled in 76 patients with grade 4 AAK. In all eyes, in order to assess preoperatively the efficiency of the limbal epithelial stem cells (LESC), the presence of corneal epithelial cells in confocal microscopy was established. The analyses included: best corrected visual acuity (BCVA), the stage of AAK and the number of corneal quadrants involved in corneal neovascularization (CNV). : Six months after surgery, the mean BCVA was 0.05 and ranged from 0.002 up to 0.1 in both groups. Improvement in BCVA occurred in 94.29% patients when *SK alone* was performed, and in 92.68% when in combination with AMT. There were no statistically significant differences in the effect of therapy depending on the type of surgery, regarding BCVA, stage of AAK and the number of quadrants with CNV. : SK alone is an effective procedure in short outcomes limited to six months for advanced AAK in association with LESC partial efficiency.

Background: Corneal squamous cell carcinoma (cSCC) is a rare neoplasm of dogs that can be treated with various modalities, principally by superficial keratectomy (SK) surgery. It is common to treat cSCC with multiple adjunctive therapies, but this may not always be practical for clinicians, clients, or patients.
Aim: This retrospective study describes the signalment of affected dogs, concurrent medical therapy, and success rate of surgical treatment of cSCC with SK surgery alone or in combination with adjunct therapy.

Aim: To evaluate the clinical efficacy and feasibility of superficial corneal opacities treated by excimer laser phototherapeutic keratectomy (PTK) combined with small incision lenticule extraction (SMILE)-derived corneal stromal lenticule transplantation.
Methods: A retrospective interventional case series of nine patients aged 12-59y with superficial corneal opacity caused by different pathologies who underwent standardized PTK combined with SMILE-derived corneal stromal lenticule transplantation was examined. Lenticule patches were fixed with fibrin glue.

Background: Corneal pathologies are among the most common reversible sight-threatening diseases globally. As such, corneal tissue transplantation (keratoplasty) techniques are evolving over time depending on the prevalence of different pathologies in each geographical area. We aim to provide a baseline information on the common keratoplasty procedures performed in our area in relation to prevalent corneal pathologies and to analyze common corneal surgical practice trends in our area.

Objective: To describe a case of presumed band keratopathy in a young cat with no known history of corneal disease who was not receiving topical phosphate-based steroids.
Animal Studied: A 10-month-old domestic shorthair cat was evaluated for severe ocular discomfort that did not improve despite the initiation of topical antibiotic treatment.
Methods: A complete ophthalmic examination and ancillary tests such as biomicroscopy and corneal cytology were performed at the time of presentation.

Objective: To determine the replication kinetics and cytopathic effect (CPE) of feline calicivirus (FCV) in feline corneal epithelial cells (FCEC).
Animals Studied: Seven archived FCV isolates and one archived feline herpesvirus type 1 (FHV-1) isolate, previously obtained from eight domestic short hair cats.
Procedures: FCV RNA was extracted for sequencing using Illumina MiSeq, to identify three genomically diverse isolates for further testing.
