The KC pathogenesis is still unknown just like the correlation with inflammatory patterns. However, environmental and genetic issues may be part of the progress of KC.

[Ocular surface and hepatitis C].

Purpose: To evaluate the outcomes of the tests used for dry eye diagnosis in patients with hepatitis C virus, and to verify if there is any relationship between the duration of illness and intensity of ocular surface changes.

Methods: 25 patients with hepatitis C virus without treatment, and 29 patients with negative serologic tests for hepatitis C virus were selected. Biomicroscopy, tear film crystallization test, tear film break-up time, evaluation of the corneal staining with 1% fluorescein sodium, Schirmer I test, ocular surface staining with 1% rose bengal and esthesiometry were performed in both groups.

Photorefractive keratectomy with mitomycin C after penetrating and lamellar keratoplasty.

Purpose: To assess the safety and efficacy of photorefractive keratectomy with mitomycin C (PRK-MMC) to correct refractive errors after corneal transplantation.

Methods: This was a prospective and noncomparative study of 36 eyes that underwent PRK-MMC after penetrating (n = 34) or lamellar (n = 2) keratoplasty. After mechanical epithelial removal and photoablation, a sponge with mitomycin C 0.
