Woong-Joo Whang, Young-Sik Yoo, Choun-Ki Joo, Geunyoung Yoon
PURPOSE: To analyze surgically induced refractive change (SIRC) and change in high-order aberration after Raindrop corneal inlay insertion, and assess the extent to which Raindrop corneal inlay insertion could correct presbyopia. DESIGN: Interventional case series. METHODS: 17 patients were included if they had a corneal thickness of 500 μm or greater and a stable manifest spherical equivalent refraction between -0.50 and +1.00 diopters.(D) The Raindrop corneal inlay (ReVision Optics, Lake Forest, CA) was implanted on the stromal bed of a femtosecond laser-assisted generated flap of non-dominant eyes...

: We describe a technique that uses a femtosecond laser (femtosecond laser pseudophakic capsulotomy) to treat capsule contraction syndrome (capsule phimosis) that may occur after cataract surgery and intraocular lens (IOL) implantation. Enlarging the capsulotomy with a femtosecond laser may offer advantages over the existing treatment methods, neodymium:YAG laser capsulotomy and manual extension of the capsulorhexis. FINANCIAL DISCLOSURE: None of the authors has a financial or proprietary interest in any material or method mentioned...

PURPOSE: To compare femtosecond laser-assisted capsulotomy with conventional manual capsulorhexis in cases of white cataract. PATIENTS AND METHODS: The prospective comparative study enrolled 80 eyes (80 patients) with white cataract that underwent either femtosecond laser-assisted cataract surgery (Group I, n=40) or conventional manual phacoemulsification (Group II, n=40) at a tertiary care ophthalmic institution. The groups were divided based on the patient's choice and affordability of the procedure...

TOPIC: To investigate the efficacy and safety of femtosecond laser-assisted cataract surgery (FLACS) relative to manual cataract surgery (MCS). CLINICAL RELEVANCE: It is unclear whether FLACS is more efficacious and safe relative to MCS. METHODS: A literature search of MEDLINE, EMBASE, and Scopus from 2007 to March 2016 was conducted. Studies containing both FLACS and MCS arms that reported on relevant efficacy and/or safety parameters were included...

PURPOSE: To evaluate clinical data and outcomes after femtosecond laser-assisted cataract surgery with the recently introduced low-energy Femto LDV Z8 laser during a 3-month follow-up. SETTING: Knappschaft Eye Clinic Sulzbach, Knappschaft Hospital Saar GmbH, Sulzbach, Germany. DESIGN: Consecutive case series. METHODS: Femtosecond laser-assisted cataract surgery was performed using the low-energy femtosecond laser. Clinical data including objective refraction, corrected distance visual acuity, central corneal thickness (CCT), endothelial cell count (ECC), and aqueous flare were evaluated 1 day, 1 week, 4 weeks, and 3 months postoperatively...

UNLABELLED: We developed a surgical technique that combines use of an iris hook and a pupil expansion ring in femtosecond laser-assisted cataract surgery complicated by insufficient mydriasis and an ectopic pupil. With this technique, the surgery, including femtosecond laser assistance, phacoemulsification, and intraocular lens implantation, can be accomplished successfully prior to iris repair. FINANCIAL DISCLOSURE: Dr. Malyugin receives travel grants from Alcon Laboratories, Inc...

AIM: To define the financial and management conditions required to introduce a femtosecond laser system for cataract surgery in a clinic using a fuzzy logic approach. METHODS: In the simulation performed in the current study, the costs associated to the acquisition and use of a commercially available femtosecond laser platform for cataract surgery (VICTUS, TECHNOLAS Perfect Vision GmbH, Bausch & Lomb, Munich, Germany) during a period of 5y were considered. A sensitivity analysis was performed considering such costs and the countable amortization of the system during this 5y period...

Achieving a formed and firm eyeball which is stably fixed in a holding device is a major challenge of surgical wet-lab training. Our innovation, the 'Spring-action Apparatus for Fixation of Eyeball (SAFE)' is a robust, simple and economical device to solve this problem. It consists of a hollow iron cylinder to which a spring-action syringe is attached. The spring-action syringe generates vacuum and enables reliable fixation of a human or animal cadaveric eye on the iron cylinder. The rise in intraocular pressure due to vacuum fixation can be varied as per need or nature of surgery being practised...

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...

The aim of this study was to evaluate corneal tissue trauma after femtosecond laser-assisted cataract surgery (FLACS) and phacoemulsification (femtophaco surgery) compared to FLACS and nanolaser emulsification (all laser surgery). This is a prospective nonrandomized clinical study conducted at the Ophthalmology Clinic, University "G. d'Annunzio" of Chieti-Pescara, Italy, involving forty-two eyes of 42 patients candidates to cataract surgery. Patients were enrolled in two groups: femtophaco surgery (group 1 with 21 eyes) and all laser surgery (group 2 with 21 eyes)...
