Abstract (english)

In the presence of the media opacities and extreme ametropia, especially in high myopia, often arises a question of expected visual acuity, e.g. after cataract extraction because of the possible degenerative changes of the choroid and retina. In the measurements were enrolled 15 patients between 45 and 60 years of age, 9 female and 6 male. We have tested preoperative retinal visual acuity by the interferometer. One month postoperatively visual acuity was measured by Snellen international charts at a distance of 6 m. Both measurements are calculated using log MAR scale. Measurements were paired and the differences are calculated and analyzed for the significance. No significance was found (p > 0.05). It was concluded that measured differences were incidental and interferometer measurements are reliable in predicting post cataract visual acuity in high myopia.

Abstract (croatian)

U prisustvu opaciteta medija i visoke ametropije, osobito kod visoke miopije, postavlja se pitanje očekivane oštine
vida, npr. nakon ekstrakcije katarakte zbog eventualnih degenerativnih promjena žilnice i mrežnice. Mjerenja su izvršena u 15 bolesnika u dobi 45–60 godina, 9 žena i 6 muškaraca. Mjerena je preoperativna retinalna oštrina interferometrijski.
Mjesec dana nakon operacije katarakte, mjerena je oštrina vida Snellenovim optotipima na udaljenosti 6 m. Obje
grupe mjerenja su preračunate u logMAR jedinice. Mjerenja su sparena i izračunate su razlike, te je analizirana signifikantnost
nađenih razlika. Nije nađena signifikantna razlika mjerenja (p>0,05). Zaključeno je da su izmjerene razlike
unutar slučajnih varijacija, te da je interferometrijsko mjerenje preoperativne retinalne oštrine vida pouzdano u prognoziranju
postoperativne oštrine vida nakon operacije katarakte u visoko kratkovidnih osoba.
