The incidence and results of laser enhancement after cataract and refractive surgery with trifocal lens implantation.

PURPOSE: To evaluate the incidence of laser enhancement following cataract surgery and refractive lens exchange (RLE) with FineVision Micro F trifocal lens implantation (PhysIOL, Liège, Belgium). METHODS: Retrospective study of patients who had undergone cataract or RLE surgery and had received a FineVision Micro F intraocular lens. Laser enhancement of residual refractive error was determined. Visual acuity (VA) assessments were performed before and after surgery: uncorrected distance VA (UCDVA), best-corrected distance VA (BCDVA), uncorrected near VA (UCNVA), plus preoperative and postoperative spherical equivalent (SE) assessments. RESULTS: Of the 1129 eyes from 596 patients, 61 (5.4%) required laser enhancement to correct residual refractive error (by group: 30/679 eyes [4.4%] cataract; 31/450 eyes [6.9%] RLE). Eleven eyes received FemtoLASIK; 50 eyes received PRK. Mean UCDVA before laser enhancement was 0.26±0.19 logMAR and 0.24±0.14 in the FemtoLASIK and PRK groups, respectively. After laser enhancement, these were 0.04±0.05 logMAR and 0.13±0.19, respectively; BCDVA values were 0.00±0.00 logMAR in the FemtoLASIK group and 0.06±0.11 in the PRK group. Laser enhancement improved UCNVA (Jaeger) from 2-3 to 1-2 in both groups. Enhancement reduced preoperative SE of -0.39±0.99 D and -0.53±0.58 D (FemtoLASIK and PRK groups, respectively) to 0.24±0.36 D and 0.04±0.47 D. CONCLUSIONS: The FineVision Micro F trifocal lens is an effective solution for gaining increased spectacle independence. The incidence of residual refractive error requiring laser enhancement is low, and laser procedures are a safe and effective solution for improving the quality of vision and patient satisfaction. SYNOPSIS: Laser enhancement rates and outcomes were determined following cataract / refractive lens exchange surgery that used a trifocal IOL. Enhancement was safe and effective and rates were low (5.4%).

A Case Report Illustrating the Spontaneous Vision Recovery After Inadvertent Central Descemetorhexis During Anterior Capsulotomy.

PURPOSE: To demonstrate an unusual mechanism of iatrogenic, central descemetorhexis (DMR) during cataract surgery and subsequent rare spontaneous visual acuity improvement within 2 months after inadvertent surgical complication. PATIENTS AND METHODS: A 81 year old woman underwent cataract surgery complicated by the loss of a 4.8X4.75 mm diameter central area of Descemet membrane. Perioperative video recording documented the DMR formation during continuous curvilinear capsulorhexis creation. RESULTS: Postoperatively, severe corneal edema with folds in the remaining Descemet membrane were observed. The patient was managed conservatively. The corneal edema gradually resolved over 2 months with improving of visual acuity from counting fingers to 20/20. CONCLUSION: Unlike Descemet membrane detachment, descemetorhexis is a rare complication after intraocular surgery. The case report identifies a previously unknown mechanism of DMR formation during anterior capsulotomy creation. Loss of Descemet membrane may be managed conservatively in an otherwise healthy cornea with good final visual outcome without the need for surgical intervention.

The correlation between echographic and histopathological findings in uveal melanoma.

PURPOSE: To correlate between the echographic and histopathological findings, and to search for important criteria for the prognosis in vivo using standardised echography. METHODS: The study included 51 consecutive patients treated by primary enucleation for choroidal or ciliary body melanoma and 30 patients who underwent secondary enucleation after failing radiotherapy treatment. All patients were treated during the period of 1998--2008 at the Eye Clinic of the 3rd Faculty of Medicine in Prague, Czech Republic. Standardised echography based on the Ossoinig method was used in this study. Histopathological processing and evaluation was performed by the Laboratory of Ocular Pathology at the same clinic. Professional statistical software (Statistica 7.1 by Statsoft, Inc.) was used for all statistical analysis. RESULTS: Statistically significant results were found in these correlations in the group of primary enucleation: US prominence vs. HP prominence (R = 0.8943, p = 0.0000), US base vs. HP base (R = 0.8060, p = 0.0000), US tumor shape vs. HP tumor shape (R = -0.7576, p = 0.0000), posterior choroidal spike condition vs. scleral invasion (R = -0.5341, p = 0.0005), TNM vs. pTNM (R = 0.7242, p = 0.0000). In the group of secondary enucleation: US prominence vs. HP prominence (R = 0.8132, p = 0.0000), US base vs. HP base (R = 0.7959, p = 0.0000). Other correlations were statistically insignificant. CONCLUSIONS: Tumor dimensions, shape of the tumor and scleral invasion are important predictors that can be in vivo reliably determined using standardised echography.

[Angiolymphoid hyperplasia with eosinophilia with bilateral involvement of the lacrimal glands]. / Angiolymphoide Hyperplasie mit Eosinophilie mit bilateralem Befall der Tränendrüsen.

BACKGROUND: Angiolymphoid hyperplasia with eosinophilia (ALHE) and Kimura's disease are two rarely occurring disorders very similar to each other; however, they are individual nosological entities. For a long time they were considered as a single disease due to the frequency of similar characteristics. The majority of authors have recently considered these diseases as two individual entities with some reciprocal specifications, both clinical as well as morphological. PATIENT: We report on the case of a 76-year old male white European who had suffered for more than six years from subcutaneous tumour formations in different parts of the body. Eyelid oedema on the right side with palpable resistance under the upper temporal edge of the orbit initially occurred five years after the first symptoms of the disease. A similar finding occurred on the left side after eight months. The tumours on both sides were surgically removed and sent for histological analysis. A unilateral recurrence of the finding appeared after one year, followed by surgical intervention and histological examination. RESULTS: Tumour infiltrate in the first two orbita excisions was topically related to lacrimal gland structures; these structures were not found in the third excision. The case was histologically diagnosed as ALHE despite some similar characteristics with Kimura's disease. The diagnosis of ALHE was histologically supported, especially by the absence of lymphatic follicle formations and fibrotisation in the infiltrate, and the identification of the appearance of epitheloid up to histiocytoid of proliferating endothelium, which forms small lumens. The diagnosis of ALHE was additionally supported by the fact that the incidence of Kimura's disease in white Europeans is very rare. CONCLUSIONS: According to our findings, both entities overlap one another, even in some characteristics considered to be distinguishing. The question arises, therefore, whether the strict separation of these nosological entities can indeed be determined with one hundred percent accuracy.
