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 …
