Influence of the anterior chamber depth on the accuracy of the intraocular lens optical power calculation in short eyes [PDF]
Клиническая практика, 2020 Background. The calculation of the optical strength of the intraocular lens (IOL) in eyes with a short anterior-posterior axis presents significant difficulties due to non-standard anatomical parameters of the eye, including the anterior chamber depth ...

Intraocular lens power calculation in short eyes [PDF]
Eye, 2007 To compare the accuracy of the Hoffer Q and SRK-T formulae in eyes below 22 mm in axial length, using biometry measured with partial coherence inferometry (PCI), without a customised ACD constant.Data were retrospectively and prospectively collected by identifying eyes of axial length below 22 mm in the records of the intraocular lens (IOL) master and ...

Image quality in polypseudophakia for extremely short eyes [PDF]
British Journal of Ophthalmology, 1999 To evaluate the image quality produced by polypseudophakia used for strongly hypermetropic and nanophthalmic eyes.Primary aberration theory and ray tracing analysis were used to calculate the optimum lens shapes and power distribution between the two intraocular lenses for two example eyes: one a strongly hypermetropic eye, the other a nanophthalmic ...

Laboratory analyses of two explanted hydrophobic acrylic intraocular lenses
Indian Journal of Ophthalmology, 2014 Two three-piece hydrophobic acrylic intraocular lenses (IOLs) were explanted from two patients at 7 and 9 years, respectively, after implantation, because of poor fundus visualisation and/or a clinically significant decrease in visual acuity related to ...
