Background and purpose: Astigmatism is a common optical dysfunction, effective on various visual outcomes and one of the important criteria of refractive surgery. The aim of present study was to evaluate the correlation between refractive, corneal and residual astigmatism in refractive surgery candidates. Materials and methods: In this cross-sectional descriptive, analytical study, 200 patient...
متن کاملImplantation of a toric phakic intraocular lens to correct high corneal astigmatism in a patient with bilateral marginal corneal degeneration.
We present a patient with marginal corneal degeneration and corneal astigmatism of more than 10.0 diopters (D). A toric phakic intraocular lens (IOL) of 7.0 D cylindrical power was implanted in both eyes to correct the high astigmatism. An uncorrected visual acuity of 20/40 was achieved in both eyes, and the best corrected visual acuity improved by 4 Snellen lines to 20/20 in both eyes. Refract...

متن کاملOptical coherence tomography-based topography determination of corneal grafts in eye bank cultivation.
Vision loss due to corneal injuries or diseases can be treated by transplantation of human corneal grafts (keratoplasty). However, quality assurance in retrieving and cultivating the tissue transplants is confined to visual and microbiological testing. To identify previous refractive surgery or morphological alterations, an automatic, noncontact, sterile screening procedure is required. Twenty-...
متن کاملCombined wedge resection and beveled penetrating relaxing incisions for the treatment of pellucid marginal corneal degeneration.
PURPOSE To evaluate a new surgical approach for the treatment of pellucid marginal corneal degeneration (PMCD). METHODS Prospective, noncomparative, interventional case series. Ten eyes of 10 consecutive patients were included in the series. Inclusion criteria were a clinical diagnosis of PMCD, topographic astigmatism >10 D, and contact lens intolerance. The patients underwent an inferior arc...
