The aim of modern micro-incision phacoemulsification combined with foldable intraocular lens implantation and femtosecond laser-assisted cataract surgery is evolving from a simple pursuit of recuperation to a refractive procedure, which involves the correction of ametropia according to preoperative and postoperative refractive conditions, especially corneal astigmatism, in order to achieve the goal of optimized postoperative uncorrected full range of vision. Nowadays, due attention to the effect of preoperative corneal astigmatism, surgery-induced astigmatism and residual astigmatism after operation is lacked, which affect postoperative visual acuity significantly...

PURPOSE: To investigate two approaches for femtosecond laser-assisted cataract surgery (FLACS) in patients with phakic intraocular lenses (IOLs). METHODS: Anterior capsulotomy and lens fragmentation were performed with an image-guided femtosecond laser. Laser treatment was performed under sterile conditions prior to (technique 1, 5 cases) or after (technique 2, 5 cases) phakic IOL explantation. RESULTS: In technique 1, gas accumulated between the phakic IOL and the anterior capsule...

PURPOSE: To compare the surgically induced astigmatism (SIA) vector, flattening effect, torque, and wound architecture following femtosecond laser and manual clear corneal incisions (CCIs). METHODS: In a double-armed, randomized, prospective case series, cataract surgery was performed for 600 eyes using femtosecond laser (300 eyes) or manual (300 eyes) 2.4-mm CCIs in temporal or superior oblique locations. SIA, flattening effect, torque, and the summated vector mean for SIA were calculated...

Background: To compare femtosecond laser-assisted versus conventional phacoemulsification in terms of visual and refractive outcomes, cumulative dissipated energy, anterior chamber inflammation and endothelial cell loss. Methods: In this retrospective cohort study, records of eyes that underwent femtosecond laser-assisted cataract surgery (FLACS) or conventional phacoemulsification (CP) were reviewed. The Victus femtosecond laser (Bausch and Lomb, Germany) was used to carry out corneal incisions, anterior capsulotomy, and lens fragmentation in FLACS procedures...

We describe a new approach for cataract surgery in ectopia lentis associated with an inadequately dilated pupil. A Malyugin ring 2.0 is first positioned in the eye to expand the pupil. One of the ring coils is then temporarily sutured to the limbal area with 10-0 polypropylene. With this maneuver, the pupillary expansion ring is placed in alignment with the center of the ectopic lens. Femtosecond laser anterior capsulotomy and lens fragmentation is then performed. Next, the temporary suture is released, a capsular hook(s) is placed to support the lens, and the lens is emulsified...

We describe a technique for the application of femtosecond laser-assisted cataract surgery in eyes with cataract and previous implantation of a foldable anterior or posterior chamber phakic intraocular lens (pIOL). In 2 eyes with an anterior chamber pIOL (angle-supported Acrysof Cachet) and 3 eyes with a posterior chamber pIOL (2 eyes with an Implantable Collamer Lens pIOL; 1 eye with a Phakic Refractive Lens), a femtosecond laser was used to create a capsulotomy, perform lens fragmentation, and create corneal incisions with the pIOL in situ...

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.

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...
