Abstract
The cornea layers are closely integrated, both structurally and in the expression of basement membrane and adhesion proteins, at the periphery, where they blend with the trabecular meshwork beams forming a transition zone. For correction of pre-surgery astigatism in cataract patients, toric intraocular lens implantation provides (i) less postoperative refractive cylinder and (ii) better uncorrected distance visual acuity than femtosecond laser-assisted astigmatic keratotomy. This is a further category of postoperative outcome in which use of femtosecond laser has not been found to be advantageous compared to alternative interventions. The authors report a non-linear relationship between pressure, maximum flow velocity and the extent of angle closure. Pressure started to elevate when the extent of angle closure was >180°, and increased dramatically when >270°. Two and three quadrants …
期刊介绍:
The British Journal of Ophthalmology (BJO) is an international peer-reviewed journal for ophthalmologists and visual science specialists. BJO publishes clinical investigations, clinical observations, and clinically relevant laboratory investigations related to ophthalmology. It also provides major reviews and also publishes manuscripts covering regional issues in a global context.
