This study examined resident exposure to and competency in new techniques for cataract removal and intraocular lens (IOL) implantation. A questionnaire was sent to 116 United States ophthalmology program directors and completed by 71. In response to the questionnaire, program directors reported that 95.3% of their graduating seniors were competent to select and implant toric IOLs and 52.3% were competent to implant capsular tension rings (CTRs). Divide and conquer (56.6%) and stop and chop (25.4%) dominated phacoemulsification teaching...

PURPOSE: To assess intraoperative morphology of clear corneal incisions (CCI) and its impact on incision-site descemet membrane detachment (DMD) in conventional phacoemulsification and femtosecond laser-assisted cataract surgery (FLACS). METHODS: Prospective comparative study of 129 eyes that underwent either conventional phacoemulsification (Group I, n = 77) or FLACS (Group II, n = 52) was undertaken at an apex tertiary care ophthalmic setup. In group I, a 2...

PURPOSE: To compare the sealability of femtosecond laser-constructed and manual clear corneal incisions (CCIs) in patients undergoing cataract surgery. METHODS: This prospective, randomized study included 62 eyes of 62 patients with cataract grade 1 to 2 (LOCS scale). The patients were randomly assigned (1:1) for creation of either manual CCI (with a 2.4-mm keratome) or femtosecond laser-assisted CCI (LENSAR, Inc., Orlando, FL) (31 eyes in each group) before undergoing femtosecond laser-assisted cataract surgery...

PURPOSE: To describe the use of a mobile femtosecond laser platform in assisting paediatric cataract surgery. METHODS: A mobile femtosecond laser was brought into the operating room and calibrated on the day of the surgery. After general anesthesia is induced, the femtosecond laser was docked onto the eyes with a liquid-filled interface, without any perioperative adaptations or additional surgical procedures. An anterior capsulotomy was created with the femtosecond laser, followed by conventional cataract extraction and intraocular lens implantation...

PURPOSE: The purpose of this study was to determine an arcuate incision (AI) nomogram to treat astigmatism during femtosecond laser-assisted cataract surgery. METHODS: This is a retrospective, cohort study. Femtosecond laser (FSL)-assisted transepithelial AIs were created at a 9.0 mm optical zone, 80% depth, centered on the limbus. We modified the manual Donnenfeld limbal relaxing incision nomogram to 70% for with-the-rule (WTR), 80% for oblique (OBL), and 100% for against-the-rule (ATR) astigmatism...

PURPOSE: Phacoemulsification is the surgical procedure of choice for cataract, providing excellent visual and safety outcomes. Femtosecond laser-assisted cataract surgery (FLACS) is an addition to the surgical armamentarium. The study aims to compare the outcomes of FLACS using LenSx™ (Alcon Inc., USA) to standard 2.2 mm clear corneal phacoemulsification. Prospective case-control, comparative, interventional study was conducted in a tertiary care center. METHODS: In each group, 55 eyes of 55 patients underwent cataract surgery using either FLACS or conventional phacoemulsification (control group)...

PURPOSE: To evaluate the safety and feasibility of a new femtosecond laser-assisted method for posterior capsule opacification (PCO) prevention. SETTING: University Eye Hospital Bochum, Bochum, Germany. DESIGN: Prospective randomized intraindividual case series. METHODS: Eyes scheduled for bilateral cataract surgery between April 2015 and January 2016 were enrolled in the study. In 1 eye, routine manual cataract surgery with intraocular lens (IOL) implantation was performed with a primary posterior laser capsulotomy as the last step in the procedure...

PURPOSE: To compare histological analyses of capsulotomies from different laser systems with regard to tissue alteration, laser spot formation, and energy settings. METHODS: Four femtosecond laser platforms approved for cataract surgery were evaluated: LenSx (Alcon Laboratories, Inc., Fort Worth, TX), Catalys (Abbott Medical Optics, Santa Ana, CA), Victus (Tecnolas/Bausch & Lomb, Munich, Germany), and LensAR (Topcon, Gamagori, Japan). Ten human anterior lens capsulotomy disks from each laser system were analyzed: five by means of light microscopy and five by transmission electron microscopy (TEM)...

The review covers different aspects of the impact of femtosecond laser-assisted cataract surgery on the state of the macular zone of the retina. Literature search has revealed inconsistency of the published data and indicated the need for a more detailed study of this problem.

The review covers morphological and clinical aspects of femtosecond laser-assisted anterior capsulotomy in cataract surgery. Literature data suggests that femtosecond laser-assisted capsulotomy is more accurate in size, shape, and centration than manual. Femtosecond laser-assisted anterior capsulotomy improves the accuracy of IOL positioning within the capsular bag.

BACKGROUND: Phakic intraocular lens (PIOL) implantation has been used to correct myopia and myopic astigmatism, although corneal decompensation can occur after implantation. Femtosecond laser-assisted cataract surgery (FLACS) has gained in popularity due to its lower postoperative astigmatism and endothelial loss. Herein, we report the use of FLACS in patients who previously received PIOL implantation and have a low corneal endothelial cell count. CASE PRESENTATION: Two patients with a previous iris-claw PIOL implantation were enrolled...

Development of non-invasive treatments for cataract calls for a sensitive diagnostic assay. We conducted a study to test whether the ratio of folded tryptophan to non-tryptophan fluorescence emission (F-factor) may be used for grading cataracts in human lenses. The F-factor was measured on aspirated lens material from eyes undergoing femtosecond laser assisted cataract surgery (FLACS) and was compared to a preoperative optical grading of cataract using Scheimpflug imaging. The preoperative optical grading allocated the cataracts to 1 of 4 categories according to the density of the cataract...

Fritz H Hengerer, Ina Conrad-Hengerer
In refractive surgery the removal of the natural lens followed by implantation of an artificial intraocular lens has been an established method to treat refractive errors. The term "clear lens exchange" separates this approach from cataract surgery, where a cloudy lens has to be removed. With regard to currently available intraocular lens technologies, there is a wide range to correct myopia, hyperopia as well as astigmatism. Trifocal or extended depth-of-focus lenses (EDOF) even with a toric component offer the patients a potential benefit to further address presbyopia, respectively...

We describe a case of femtosecond laser-assisted cataract surgery (FLACS) in an eye with multiple comorbidities, including retinal detachment surgery, high myopia, posterior chamber phakic intraocular lens (PC pIOL) and residual, emulsified, silicone oil located in the anterior chamber. FLACS was affected by the optical blockage, but the incomplete capsular tear was recoverable. The case suggests that silicone oil bubbles concentrated at the dome of the posterior corneal surface, along with the PC pIOL optic edges and scars after corneal astigmatic relaxing incisions can lead to incomplete anterior capsulotomy...

Peiqing Chen, Yanan Zhu, Ke Yao
BACKGROUND: Femtosecond laser-assisted cataract surgery (FLACS) has grown in popularity among ophthalmologists as a novel technique. However, descemet membrane detachment (DMD) began to be found as the complication after FLACS. We report a case of serious DMD following FLACS due to the inappropriate incision design. CASE PRESENTATION: An 85-year-old man with apparent cornea arcus senilis underwent femtosecond laser-assisted cataract surgery in his right eye. A biplanar model was chosen for the main incision...

PURPOSE OF REVIEW: Femtosecond laser-assisted cataract surgery (FLACS) has gained popularity in recent years with the new technology suggesting potential improvements in clinical and safety outcomes over conventional phacoemulsification cataract surgery (PCS). A decade since the advent of FLACS has given time and experience for laser technology to develop in maturity, and better quality evidence to become available. This review evaluates current evidence on the clinical and safety outcomes for FLACS in comparison to PCS...
