keratoconus

Use of tomographic imaging can help detect keratoconus earlierTomographic imaging gives surgeons a fuller view of the eye, making it easier to detect early signs of keratoconus.
Ten-year data promising in combined CXL approach for keratoconusClinicians evaluated the refractive, pachymetric, topometric, and visual rehabilitation changes with the Athens Protocol applied in patients with keratoconus. Joanna Kontari, MD, highlights some of the research findings and implications.
Epithelial thickness mapping in the care of refractive surgery patientsCorneal epithelial thickness mapping may become an easy and objective tool in the diagnosis of biomechanically unstable corneas and perhaps a multitude of anterior segment disorders.
Opportunities and challenges in the world of ophthalmology in 2018As another year comes to an end, five members of Ophthalmology Times Europe’s Editorial Advisory Board reflect and share their perspectives on the exciting opportunities that lie ahead for ophthalmologists in 2018, whilst also considering the potential challenges.
Adopting a multidiagnostic method for characterising the anterior segmentA multidiagnostic device is able to provide consistent measurements of refraction and ocular aberrations in healthy eyes. The consistency of refractive measurements is not dependent on the magnitude of the refractive error, with the same precision ability for moderate to high myopia and for hyperopia.
Leveraging the evidence for patient care todayTimes are changing, and the amount of information coming at us from all directions can easily be overwhelming. This information—whether true or false—is unrelenting and has increased in magnitude over the past five years. Part of it may be the natural progression of one’s career and the expansion of one’s network, but most of it is just the sheer volume that is at our fingertips.
CXL demands continuity of careCrosslinking meets the previously unmet needs of progressive keratoconus patients and provides an opportunity to increase engagement with optometrists, explain John Berdahl, MD, and George O. Waring IV, MD.
Top 10 questions about cross-linkingKeratoconus treatment has changed much over the past several years. Avedro’s U.S. Food and Drug Administration (FDA) approval of corneal cross-linking has given more patients hope for better vision.
How to improve IOL power calculations in keratoconusOne source of error in IOL power calculation is the use of the classical keratometric approach for the characterisation of the corneal optics. This approach is based on the assumption of only one corneal surface and a fictitious index of refraction (keratometric index, nk) for obtaining an estimation of the corneal power (Pk).
OCTs ushering new era in complex contact lens fittingsComplex contact lenses, including scleral lenses, have unique fitting considerations that may be augmented with additional optic scans, says Jeffrey Sonsino, OD, FAAO, of Nashville, TN, at SECO 2017.
