Femtosecond cataract surgery

B E Malyugin, N S Anisimova
In certain cases intraoperative pupil dilation during cataract surgery may be necessary to improve the visualization of intraocular structures and assure the atraumatic nature of surgical manipulations. The article reviews a wide range of pupil expanders, their historical aspects and possibilities of their application in modern cataract surgery.

PURPOSE: Femtosecond laser-assisted cataract surgery (FLACS) has emerged as an alternative to manual cataract surgery (MCS) for corneal incision and capsulorhexis creation, as well as nuclear fragmentation. This study compares postoperative refractive and visual outcomes in eyes receiving MCS or FLACS. DESIGN: Single-center, comparative, retrospective cohort analysis. PARTICIPANTS: Consecutive eyes receiving FLACS and MCS from July 1, 2012, to July 31, 2015, at a single tertiary care center...

Cataract surgery can cause macular thickness change. We used optical coherence tomography (OCT) to assess the macular thickness of different regions after femtosecond laser-assisted cataract surgery of age-related cataracts (ARC) and myopia cases with cataract (myopia group). Fifty eyes of 50 patients in ARC group and fifty eyes of 50 patients in myopia with cataract group were included. All study underwent femtosecond laser-assisted cataract surgery and macular thickness of was measured at pre-operation and 1 week, 1 month after surgery...

AIMS: To test a hypothesis that cataract operating room (OR) productivity can be improved with a femtosecond laser (FL) using a hub-and-spoke model and whether any increase in productivity can offset additional costs relating to the FL. METHODS: 400 eyes of 400 patients were enrolled in a randomised-controlled trial comparing FL-assisted cataract surgery (FLACS) with conventional phacoemulsification surgery (CPS). 299 of 400 operations were performed on designated high-volume theatre lists (FLACS=134, CPS=165), where a hub-and-spoke FLACS model (1×FL, 2×ORs=2:1) was compared with independent CPS theatre lists...

OBJECTIVE: To determine the time needed to perform a femtosecond laser-assisted cataract surgery (FLACS) and its effect on the efficiency of cataract surgery flow in a Canadian public health centre. DESIGN: Retrospective chart review. PARTICIPANTS: Patients who had cataract surgery performed in the first 3 months of femtosecond laser (FSL) technology use were compared with patients who had conventional phacoemulsification in the 3 months before FSL installation at Brandon Regional Health Centre (Brandon, Man...

BACKGROUND: To evaluate the efficiency and practicality of femtosecond laser assisted cataract surgery (FLACS) in a public teaching hospital setting using a mobile FLACS system compared to conventional phacoemulsification cataract surgery (CPCS). METHODS: Ninety eyes from 90 patients underwent either FLACS or CPCS (45 in each group). Cataracts were graded using the Lens Opacities Classification System III system. Outcome measures included total surgery duration, femtosecond laser treatment time, vacuum time (VT), total phacoemulsification time (TPT) and total phacoemulsification power (TPP)...

PURPOSE: To evaluate changes in clinical practice in the field of refractive surgery in Korea over the past 10 years. METHODS: A survey consisting of 59 multiple-choice questions regarding the preferred types of refractive surgery, excimer laser machine, and presbyopia surgery was mailed to 742 members of the Korean Society of Cataract and Refractive Surgery in January 2016, and 50 members responded to the survey. These data were compared with the 2005 or 2007 survey results...

PURPOSE: To evaluate differences in postoperative central macular thickness, central macular volume, corrected distance visual acuity (CDVA), and number of intravitreal anti-vascular endothelial growth factor (VEGF) injections between conventional and femtosecond laser-assisted cataract surgery in wet age-related macular degeneration (AMD). SETTING: Tertiary referral center, Lucerne, Switzerland. DESIGN: Retrospective case series. METHODS: Consecutive patients with AMD and cataract were enrolled between January 2010 and December 2015...

PURPOSE: To evaluate the effect of fragmentation patterns (pie pattern versus grid pattern) on effective phacoemulsification time (EPT). SETTING: Department of Ophthalmology, Goethe University, Frankfurt am Main, Germany. DESIGN: Retrospective case series. METHODS: Eyes that had femtosecond laser-assisted cataract surgery were included. One half of the group was treated with the pie pattern. The preoperative lens density was evaluated by Scheimpflug imaging (Pentacam)...

PURPOSE: To describe a large cohort of femtosecond laser-assisted cataract surgeries in terms of baseline characteristics and the related outcomes. SETTING: Eighteen cataract surgery clinics in 9 European countries and Australia. DESIGN: Prospective multicenter case series. METHODS: Data on consecutive eyes having femtosecond laser-assisted cataract surgery in the participating clinics were entered in the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO)...

PURPOSE: To compare the expected versus actual position and dimension of corneal incisions during femtosecond laser-assisted cataract surgery. SETTING: Private Ophthalmic Clinic, Sydney, NSW, Australia. DESIGN: Retrospective case series. METHODS: Video recordings of femtosecond laser-assisted cataract surgery with a Lensx laser were reviewed. The deviation of the main and 2 secondary incisions from the expected position were correlated with globe tilt, globe displacement, and biometric data...

In femtosecond laser-assisted cataract surgery, the parameter such as horizontal spot spacing and energy level can be adjusted. Although there have been several studies reported on various laser systems, showing the effects of varying energy levels and horizontal spot spacing on lens capsulotomy cut edges, none have been reported on the Catalys laser system (Abbott Medical Optics, Inc., Santa Ana, CA). The aim of this study is to evaluate, using scanning electron microscopy (SEM), the quality of the cut edges of the laser lens capsulotomy obtained using the Catalys Laser System, using different horizontal spot spacing and energy levels, and to determine the ideal parameters based on SEM results...

Purpose: Femtosecond laser-assisted cataract surgery (FLACS) is an increasingly common procedure. Most laser systems require corneal applanation and thereby increase intraocular pressure (IOP). The purpose of the present study was to evaluate the IOP changes that occur during the FLACS procedure performed using the Catalys femtosecond laser system. Methods: IOP was measured by direct cannulation of the vitreous body of porcine cadaver eyes (N = 20). By inserting a second cannula connected to a water column, all the eyes were set to a baseline IOP of 20 mm Hg...

Purpose: This paper is a case report of the use of femtosecond laser for cataract surgery to implant an implantable miniature telescope for a patient with large central areas of geographic atrophy. Observations: On postoperative day 1 the patient's uncorrected visual acuity at near was 20/50. The cornea was clear and the patient reported no problem with navigation without occupational therapy training. Conclusions and importance: To our knowledge and confirmed by the manufacturer of the implantable miniature telescope this is the first case ever reported of a patient who has undergone femtosecond laser cataract surgery with corneal astigmatism correction and implantation of the implantable miniature telescope...
