[Intraocular lens power calculation in patients after keratorefractive surgery--personal experience].

PURPOSE: To assess the efficacy of intraocular lens power calculation in patients with previous corneal refractive surgery. MATERIAL AND METHODS: Retrospective analysis of patients after laser refractive procedures, in whom cataract removal with phacoemulsification method was performed. Corneal power, which in conventional measurements after refractive surgery tends to increase value and results in postoperative hyperopic shift, were calculated with five methods, and the results were compared. To asses IOL power SRK/T formula was used. RESULTS: Mean spherical equivalent three months after procedures according to target refraction in examined patients ranged from -1.00 to +1.75 D. The difference between obtained and target refraction in 55% of patients ranged from -0.50 to +0.50, and in 77% from -0.75D to +0.75D. Best results were obtained in calculations performed with Rossa method. The least effective appeared to be traditional IOL power calculation method without correcting factors. CONCLUSIONS: In patients after laser correction of myopia, value of the measured keratometry should always be corrected. The most effective is Rosa method in combination with SRK/T calculation algorithm.

[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.
