[Trends in indications of perforating keratoplasty at the Department of Ophthalmology, Faculty Hospital, Brno, Czech Republic, E.U., during the period 2008-2012].

Introduction: The aim of the study is retrospective analysis of perforating keratoplasty (PKP) indications at the Department of Ophthalmology, Faculty Hospital, Masaryk University, Brno, Czech Republic, E.U., during the period of 5 years, from January 1st, 2008 to December 31st, 2012.

[The use of confocal corneal microscopy in the Cogan microcystic dystrophy diagnosis and follow-up of the ultrastructural changes after phototherapeutic keratectomy].

Unlabelled: Confocal microscopy represents modern, non-invasive, semi-contact examination method making possible to visualize separate corneal layers (from the endothel to the epithel) in high resolution. Phototherapeutic keratectomy (PTK) is a method using argon-fluoride laser with 193 nm wavelength to treat corneal surface diseases.

Aim: To evaluate the use of confocal microscopy for epithelial basal membrane dystrophy diagnosis (Cogan microcystic dystrophy) and following corneal ultra-structural changes in vivo after PTK.

[DMEK (Descemet membrane endothelial keratoplasty)--early and late postoperative complications].

Unlabelled: The authors refer to the cross-sectional study of surgical technique, operation, early and late postoperative complications in the first 30 patients after DMEK (Descemet membrane endothelial keratoplasty).

Setting And Methods: The group comprised 17 women and 13 men with an average age of 62 years (SD 12.2).

[Corneal cross-linking--modern method of keratoconus treatment].

Purpose: The aim of research study was to evaluate the effect of corneal cross-linking (CXL) in the frame of patients with progressive keratoconus 1 year after treatment.

Methods: There were 40 eyes of 35 patients with mean age 28, 45 +/- 9.3 (SD) (15 to 48 years) included in the study.

[Changes of higher order aberrations and contrast sensitivity after standard photorefractive keratectomy].

Unlabelled: The aim of the prospective study was to evaluate higher order aberrations and contrast sensitivity after photorefractive keratectomy (PRK) using the standard photoablation profile.

Materials And Methods: The group consisted of 37 patients (69 eyes), the mean age 27.2 +/- 4.

[Contrast sensitivity and higher order aberration after conventional LASIK treatment].

Aim: The aim of the prospective study was to evaluate photopic high-contrast visual acuity, mesopic contrast sensitivity, and high order aberrations, to compare changes and post-operative development of those parameters and to analyze the dependence among aberrations and contrast sensitivity after conventional LASIK treatment.

Materials And Methods: The authors followed-up patients treated by means of refractive LASIK treatment during the period from November 2006 to November 2007. The authors analyzed 51 eyes (31 patients).
