Purpose: To identify preoperative and intraoperative factors associated with a capsule complication; that is, a capsule tear or a zonular dehiscence during cataract surgery.
Setting: Ten ophthalmic surgery departments in Sweden.
Methods: A retrospective review of files of patients with a capsule complication and control patients with no complication operated on in 2003 was performed.
Evaluation of aqueous outflow facility in patients with high intraocular pressure after cataract surgery.
Ophthalmic Surg Lasers Imaging
January 2007
Background And Objective: To study whether patients with a marked elevation of intraocular pressure (IOP) the day after cataract surgery may have a chronically impaired aqueous outflow.
Patients And Methods: In 128 consecutive patients, IOP was measured both preoperatively and the day after phacoemulsification and intraocular lens implantation. In the late postoperative period, aqueous outflow facility (C-value) was measured with pneumatonography in patients (n = 7) who experienced a postoperative IOP increase of at least 20 mm Hg and in patients (n = 11) with a difference between preoperative and postoperative IOP of not more than 2 mm Hg.

Purpose: To clinically evaluate the lens haptic plane (LHP) concept in combination with thick-lens ray tracing for intraocular lens (IOL) power calculation.
Setting: St. Erik's Eye Hospital, Stockholm, Sweden.

Purpose: To compare 2 A-scan instruments with regard to differences in measured results for the same patient sample.
