[Evaluation of the usefulness of corneal scanning topography performed with Orbscan for the localization of corneal transplantation due to keratoconus].

PURPOSE: Evaluation of the usefulness of corneal scanning topography performed with Orbscan for the localization of corneal graft due to keratoconus. MATERIAL AND METHODS: We examined 33 eyes in 33 individuals (23 men 10 women) during one year 2000/2001. Corneal topography was performed with Orbscan apparatus before the transplantation of the cornea due to the keratoconus. Trepanning depended of the thickness of peripheral cornea. Visual acuity without correction was compared with the control group of 33 eyes, after corneal transplantation done due to the corneal cone between 1998-1999, without consideration of scanning topography. RESULTS: Significant differences in the post-surgical visual acuity in favor of the examined group in the range from 5/5 to 5/7 and from 5/25 to 5/50 were observed. CONCLUSIONS: Scanning corneal topography will probably facilitate proper qualification for the transplantation and better postoperative visual acuity.

[Posterior polymorphous corneal dystrophy--diagnostic difficulties].

PURPOSE: This paper describes complications due to the posterior polymorphous corneal dystrophy in one patient. MATERIAL AND METHODS: Medical history of misdiagnosis and subsequent wrong procedures, to which patient with binocular posterior polymorphous corneal dystrophy was exposed, where presented. The eye misdiagnosed with profound keratitis was initially treated with high doses of steroids, what could possibly lead to extensive fungal corneal ulceration and complicated cataract. RESULTS: Thanks to the detailed examination of the fellow eye in the slit lamp and specular microscope, correct diagnosis was made. CONCLUSIONS: Since posterior polymorphous corneal dystrophy is one of the rare conditions, especially with coexisting eye irritation, wrong diagnosis of this disorder is possible to be made. Therefore, extremely important in every day ophthalmological practice precise examination of the both eyes and special care during steroid treatment is essential.

[Penetrating keratoplasty in keratoconus in years 1990 and 1999].

The purpose of this study was to compare grafts performed because of keratoconus in our clinic in years 1990-1999. These years were chosen for analysis because in this time some methods of grafting were changed, particularly: material for transplantation, graft's size, method of trephination and graft suturing, also management after operation. The study included 51 patients (17 females, 34 males) with keratoconus, aged 16 to 46 (mean age 31.3), which have had penetrating keratoplasty done in years 1990-1999. The amount of surgery, sex of patients, preoperative preparation, kind of graft material, technique of operation, methods of graft suturing, postoperative procedure, the time of patients hospitalization, time of suture removing, postoperative visual acuity and complication were compared.
