    Operacja za膰my jest obecnie najcz臋艣ciej wykonywan膮 procedur膮 chirurgiczn膮 w krajach rozwini臋tych. Coraz cz臋艣ciej traktowana jest r贸wnie偶 jako zabieg refrakcyjny, a zastosowanie soczewek z grupy premium (asferycznych, torycznych, wieloogniskowych) pozwala pacjentowi na uniezale偶nienie si臋 od korekcji okularowej i uzyskanie dobrej jako艣ci widzenia do wszystkich odleg艂o艣ci, nawet je艣li przed zabiegiem wyst臋powa艂y starczowzroczno艣膰 czy astygmatyzm. Wraz z popraw膮 standard贸w leczenia operacyjnego zwi臋kszaj膮 si臋 r贸wnie偶 oczekiwania pacjent贸w. Kluczowe jest uzyskanie jak najlepszej refrakcji pooperacyjnej. W tym celu przed operacj膮 nale偶y dokona膰 precyzyjnych pomiar贸w biometrycznych ga艂ki ocznej i wybra膰 optymaln膮 formu艂臋 obliczeniow膮 do kalkulacji mocy wszczepianej soczewki. Celem pracy jest przedstawienie aktualnych metod przeprowadzania bada艅 biometrycznych i najnowszych dost臋pnych w Polsce aparat贸w s艂u偶膮cych do biometrii oraz por贸wnanie ich funkcji. Dok艂adne zrozumienie zalet i ogranicze艅 dost臋pnej na rynku aparatury oraz poznanie podstawowych zasad kalkulacji mocy wszczepianych soczewek pozwoli usprawni膰 procedury przeprowadzania bada艅 i osi膮ga膰 optymalne warto艣ci refrakcji pooperacyjnej.Cataract surgery is currently the most frequently performed surgical procedure in developed countries. In some cases it is also regarded as refractive procedure, and the use of premium intraocular lenses (aspheric, toric, multifocal) allows the patient to become spectacle independent. The improvement of surgical treatment results in rising expectations of patients. The key issue is to achieve the desired refractive outcome. Essential for this purpose are precise measurements of the eye, and selection of the optimal IOL calculation formula. The aim of this paper is to present current techniques of ocular biometry and new biometry devices available in Poland, along with a comparison of their functions. Good understanding the advantages and limitations of the current technology allows to perform measurements efficiently and to achieve highly accurate refractive outcomes

    The Role of Systemic Antimicrobials in the Treatment of Endophthalmitis: A Review and an International Perspective

    Abstract Background The optimal management of patients with endophthalmitis is challenging and includes both intravitreal and, in some cases, systemic antimicrobials. Systemic antimicrobials may be administered either intravenously or orally. In this article we review systemic antimicrobial options currently available for the treatment of types of endophthalmitis and the role of systemic antimicrobials (antibiotics and antifungals) in these treatments. Review While systemic antimicrobials are not universally utilized in the management of endophthalmitis, they may be helpful in some circumstances. The blood鈥搑etinal barrier affects the penetration of systemic medications into the posterior segment of the eye differently; for example, moxifloxacin and imipenem cross the blood鈥搑etinal barrier relatively easily while vancomycin and amikacin do not. However, inflammation, including endophthalmitis, may disrupt the blood鈥搑etinal barrier, enhancing the penetration of systemic agents into the eye. Conclusion Systemic antimicrobials may be particularly beneficial in patients with certain types of endophthalmitis; as such, they are standard treatment in the management of endogenous endophthalmitis (fungal and bacterial) and also widely used for prophylaxis and treatment聽of open-globe injuries. Although systemic antimicrobials are used in some patients with acute-onset postoperative endophthalmitis following cataract surgery, the literature generally does not support this practice. It is noted that there are currently no randomized clinical trials demonstrating a benefit of systemic antibiotics for any category of endophthalmitis
