  To evaluate the refractive results in patients with intraocular lenses fixated in the sulcus of posterior chamber. Sulcus fixation causes a more anterior position of IOL than had been intended duringTo evaluate the refractive results in patients with intraocular lenses fixated in the sulcus of posterior chamber. Sulcus fixation causes a more anterior position of IOL than had been intended during the preoperative power calculation. A lack of correction of the IOL's power results in a myopic shift. 27 patients (27 eyes) who underwent cataract surgery by phacoemulsification and foldable IOL MA60BM sulcus fixation due to a posterior capsule rupture at the Department of Ophthalmology, Medical University of Warsaw. The position of the IOL was confirmed by ultrabiomicroscopy. The study included patients with axial lengths ranging from 22 to 25 mm. Patients who suffered from a corneal astigmatism of > 1,00 Dcyl prior to the surgery were excluded from the study. The study also excluded patients with vitreous loss as this causes the anterior chamber to become deeper after vitrectomy, and consequently the IOL might sit in a more posterior position. The difference between the predicted and the postoperative refraction was evaluated. The mean visual acuity was significantly better after cataract surgery. The best corrected visual acuity (BCVA) was 1.0, which occurred in 19 cases (70%). The myopic shift, which was assessed as a mean difference between the predicted and the postoperative refraction after sulcus fixation, was 1.25 D. In order to avoid a myopic shift in the case of sulcus fixation, the IOL power calculation should be adjusted accordingly. The authors recommend that the IOL power should be reduced by approximately 1.25 to 1.50 D in emetropic eyes.

  Evaluation of the measurement accuracy using a new optical biometer LenStar LS 900 (Haag Strait) and comparison according to the IOL Master V.5 (Zeiss) device. In a prospective clinical studyEvaluation of the measurement accuracy using a new optical biometer LenStar LS 900 (Haag Strait) and comparison according to the IOL Master V.5 (Zeiss) device. In a prospective clinical study biometric measurements along with artificial lens power calculation using the LenStar LS 900 device were performed. A total number of 106 patients qualified for a cataract extraction procedure were included in the study. Measurements along with lens power calculation were repeated using the IOL Master V.5. device. Results were elaborated using Pearson's correlation and Bland-Altman plot. Measurements were performed in 204 eyes of 106 patients. Mean values and ranges of biometry results were as follows: 23.46 +/- 2.81 mm [20.79-29.80] for IOL Master, and 23.47 +/- 2.83 mm [20.79-29.86] for LenStar LS 900. In keratometry for flat meridian (K1) the following data was obtained: mean 43.24 +/- 3.22 D [range 38.27-47.94] for IOL Master and 42.44 +/- 3.15 D [38.27-47.94] for LenStar LS 900. For steep meridian (K2) the data obtained were 44.14 +/- 3.40 D; [39.29-49.13] and 43.27 +/- 3.34 D [38.61-48.4] respectively. The obtained calculation results for each eye were as follows: mean 21.23 +/- 8.07, [range 3.25-28.99] for Hagis formula, 21.14 +/- 6.90; [4.83-27.6] for SRK II, 21.04 +/- 7.78; [3.05-28.05] for SRK/T, 21.09 +/- 8.13; [2.43-28.61] for Holladay using IOL Master and 21.41 +/- 8.23; [2.99-29.15] for Haigis; 21.24 +/- 7.00; [4.6-27.71] for SRK II, 21.13 +/- 7.90; [2.76-28.18] for SRK/T; 21.09 +/- 8.13; [2.16-28.76] for Holladay using LenStar LS 900. The LenStar LS 900 device enables to perform accurate and repetitive biometric measurements and implant power calculations. Implant calculation results obtained using the LenStar LS 900 device are comparable to those achieved using the IOL Master V.5 device, which has been commonly accepted as standard for over a decade. The use of both devices is limited by significant lens opacification and posterior capsule calcification. In such cases, additional ultrasound biometry should be performed. Keratometry results obtained using both devices should not be used alternatively because of the different measurement methods and different refraction indexes. The LenStar LS 900 device comparing to the IOL Master additionally enables pachymetry, macular retinal thickness, lens thickens and pupil diameter measurement. Accuracy of those measurements should be studied in the future.

  PURPOSE: To describe the in vivo conocal microscopic findings in posterior polymorphous dystrophy (PPD). MATERIAL AND METHODS: Eleven patients (22 eyes) with PPD suspected or clinically diagnosedPURPOSE: To describe the in vivo conocal microscopic findings in posterior polymorphous dystrophy (PPD). MATERIAL AND METHODS: Eleven patients (22 eyes) with PPD suspected or clinically diagnosed were examined using scanning slit white light confocal microscopy (ConfoScan 3, Nidek Technologies). Results: Endothelial cell densities ranged from 716 to 2380 cells/mm2 and endothelial polymegathism was noted in all cases. In 5 cases PPD changes was reported unilateral. Confocal microscopy demonstrated a variety of vesicular and linear abnormalities. In 13 eyes exhibited bright, nucleus-like structures within endothelial cells. Stromal edema was noted in 4 cases. CONCLUSIONS: To our knowledge, we present the largest case series of PPD imaged by in vivo confocal microscopy. Confocal microscopy images of PPD are very characteristic. This method allows to confirm presumptive or to identify final diagnosis. Our study enhances the value of confocal microscopy in detection and monitoring corneal abnormalities.

  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 laserPURPOSE: 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.

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.

  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,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.
