Astigmatism in cataract patientsMost candidates for cataract surgery have a degree of corneal astigmatism, which should be considered by intraocular lens (IOL) manufacturers, concluded a study published in the January issue of the Journal of Cataract & Refractive Surgery.
Best tools for measuring IOP in KC patientsThe Pascal dynamic contour tonometer (DCT) and Reichert ocular response analyser (ORA) are the best tools for measuring corneal-compensated intraocular pressure (IOPcc) in patients with keratoconus (KC), according to study results published in the British Journal of Ophthalmology, December.
POAG development: risk factorsPatients with thicker corneas are less likely to progress to primary open angle glaucoma (POAG) from ocular hypertension (OHT), according to a study published in the June 2008 issue of Contact Lens and Anterior Eye.
