BACKGROUND: To evaluate intraocular pressure (IOP) using the application of a novel liquid patient interface for femtosecond laser-assisted cataract surgery with the FEMTO LDV Z8. METHODS: IOP was evaluated in enucleated porcine eyes prior, during and after the application of the Femto LDV Z8 liquid patient interface (Ziemer Ophthalmic Systems, Switzerland) using intracameral cannulation (n=20), intravitreal cannulation (n=20), rebound tonometry (n=20) and indentation tonometry (n=20)...

Objective. This meta-analysis aimed to compare the outcomes and postoperative complications between femtosecond laser-assisted cataract surgery (FLACS) and conventional phacoemulsification cataract surgery (CPCS). Methods. Bibliographic databases, including PubMed, Embase, and Cochrane library, were systematically searched for references on or before September 2015 regarding the outcomes and complications by FLACS or CPCS. Data on corneal endothelial cell loss, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), refractive outcomes, and postoperative complications were retrieved...

Objective: To assess the effect of femtosecond laser-assisted anterior capsulotomy in intumescent white cataract surgery. Methods: Retrospective case series study. One hundred and fifty cataract patients (150 eyes) from June 2014 to June 2015 in Wuhan Aier ophthalmology hospital were enrolled in this study. They were divided into three groups: 50 intumescent white cataract patients (50 eyes) in the study group were performed femtosecond laser-assisted capsulotomy (LenSx system) operation selectively. Fifty intumescent white cataract patients (50 eyes) underwent normal manual continuous circular capsulorhexis as the control group 1...

PURPOSE: To use optical coherence tomography (OCT) to evaluate the femtosecond laser intrastromal incisions made during cataract surgery to reduce corneal astigmatism. DESIGN: Retrospective case series. PARTICIPANTS: Seventy-seven eyes of 77 patients. METHODS: Paired intrastromal incisions were created using the Catalys femtosecond laser (Abbott Medical Optics, Inc., Santa Ana, CA). The planned intrastromal incision parameters were 20% uncut anterior, 20% uncut posterior, midpoint depth of 50%, and 90° side cut angle...

A 51-year-old woman developed severe fibrosis and occlusion of the visual axis in 1 eye, maintaining a pinhole aperture in the fellow eye, 2 months after uneventful cataract surgery and implantation of a hydrophilic trifocal intraocular lens in the capsular bag. She had not exhibited any risk factor for anterior capsule contraction preoperatively. Femtosecond laser-assisted capsulotomy with a fluid-filled interface system was used to perform a simultaneous anterior capsulotomy in both eyes. Preoperative calculations of the incision depth of the capsulotomy were performed using optical coherence tomography (OCT) and adjusted intraoperatively with the OCT system of the femtosecond laser...

We describe a simple steep-axis marking technique that uses a corneal analyzer (OPD III scan) during arcuate keratotomy in femtosecond laser-assisted cataract surgery. The technique requires a single reference mark at the limbus, which does not have to be on the horizontal axis. Using the corneal analyzer, the angle between the steep axis and the reference line between the reference mark and the center of the cornea can be determined. The angle from the reference mark is used intraoperatively to locate the steep axis...

AIMS: To develop financial models which offset additional costs associated with femtosecond laser (FL)-assisted cataract surgery (FLACS) against improvements in productivity and to determine important factors relating to its implementation into the National Health Service (NHS). METHODS: FL platforms are expensive, in initial purchase and running costs. The additional costs associated with FL technology might be offset by an increase in surgical efficiency. Using a 'hub and spoke' model to provide high-volume cataract surgery, we designed a financial model, comparing FLACS against conventional phacoemulsification surgery (CPS)...
