Technology in cataract surgery is constantly evolving to meet the goals of both surgeons and patients. Recent major advances in refractive cataract surgery include innovations in preoperative and intraoperative diagnostics, femtosecond laser-assisted cataract surgery (FLACS), and a new generation of intraocular lenses (IOLs). This paper presents the latest technologies in each of these major categories and discusses how these contributions serve to improve cataract surgery outcomes in a safe, effective, and predictable manner...

BACKGROUND: Cataract is the leading cause of blindness in the world, and cataract surgery is one of the most commonly performed operations in the Western world. Preferred surgical techniques have changed dramatically over the past half century with associated improvements in outcomes and safety. Femtosecond laser platforms that can accurately and reproducibly perform key steps in cataract surgery, including corneal incisions, capsulotomy and lens fragmentation, are now available. The potential advantages of laser-assisted surgery are broad, and include greater safety and better visual outcomes through greater precision and reproducibility...

PURPOSE: To compare astigmatic outcomes in patients with bilateral cataracts having toric intraocular lens (IOL) implantation with intraoperative aberrometry measurements in 1 eye and standard power calculation and a toric IOL calculator with inked axis marking in the contralateral eye. SETTING: Twelve sites in the United States. DESIGN: Prospective cohort study. METHODS: The eye with the more visually significant cataract was randomized to intraoperative aberrometry measurements (Ocular Response Analyzer with Verifeye) or standard preoperative biometry and use of a toric calculator with the contralateral eye automatically assigned to the other group...

PURPOSE: To determine the efficacy of femtosecond laser-assisted cataract surgery in eyes with radial keratometry. METHODS: Femtosecond laser-assisted cataract surgery was performed in 3 patients (6 eyes) who had six to eight radial keratotomy incisions. RESULTS: In all cases, the anterior segment of the eye was visualized with integrated three-dimensional optical coherence tomography and it was possible to position the laser corneal incisions between the radial keratotomy incisions...

PURPOSE: To analyze the impact of learning curve on operating room (OR) times, femtosecond laser times, procedure time (time for laser and non-laser steps combined), and surgical time (procedure time minus transfer and preoperative times) during transition to femtosecond laser-assisted cataract surgery (FLACS) and comparison with conventional phacoemulsification. METHODS: In this retrospective, comparative case series, patients undergoing FLACS by an experienced surgeon between November 2012 and June 2014 were reviewed using the Catalys Precision Laser system (Abbott Medical Optics, Santa Ana, CA)...

Femtosecond laser technology has become widely adopted by ophthalmic surgeons. The purpose of this study is to discuss applications and advantages of femtosecond lasers over traditional manual techniques, and related unique complications in cataract surgery and corneal refractive surgical procedures, including: LASIK flap creation, intracorneal ring segment implantation, presbyopic treatments, keratoplasty, astigmatic keratotomy, and intrastromal lenticule procedures.

PURPOSE: To report two cases of cataract with phakic intraocular lens (PIOL) in situ that underwent femtosecond laser-assisted cataract surgery (FLACS) along with PIOL explantation. METHODS: Case reports. RESULTS: The first case had an implantable collamer lens (ICL) in situ. A well-centered, circular femtosecond laser capsulotomy was achieved. Incomplete nucleotomy was noted due to the entrapment of cavitation bubbles beneath the ICL. Postoperative visual acuity was 20/20...
