Utah Eye Centers Now Offers the Latest Advance In Laser Eye Surgery The New VICTUS® Femtosecond Laser Platform, from Bausch + Lomb is Designed to Support Positive Patient Experience and Outstanding Visual Results in Cataract and LASIK Procedures FOR RELEASE April 17, 2015 Ogden, Utah— Utah Eye Centers, the leading comprehensive ophthalmology practice in northern Utah, announced today the Mount Ogden facility now offers eye surgery for cataracts and LASIK with an advanced laser system, the VICTUS® femtosecond laser platform. They are the only practice north of Salt Lake City with a fixed site femtosecond laser for cataracts and LASIK. The versatile VICTUS platform is designed to provide greater precision compared to manual cataract and LASIK surgery techniques. According to Scott Sykes, M.D., the Victus laser is the only laser approved to perform treatments for both cataract and LASIK surgeries. "With the VICTUS platform, we are able to automate some of the steps that we have commonly performed manually," said Mark Ballif, M.D. "While we have performed thousands of successful cataract and LASIK surgeries, the VICTUS platform helps us to improve the procedures to give our patients the best outcomes possible." The VICTUS platform features a sophisticated, curved patient interface with computer-monitored pressure sensors designed to provide comfort during the procedure.

(YAG) Laser Capsulotomy Reference Number: CP.VP.65 Coding Implications Last Review Date: 12/2020 Revision Log
Clinical Policy: Yttrium Aluminium Garnet (YAG) Laser Capsulotomy Reference Number: CP.VP.65 Coding Implications Last Review Date: 12/2020 Revision Log See Important Reminder at the end of this policy for important regulatory and legal information. Description This policy describes the medical necessity requirements for yttrium aluminium garnet (YAG) laser capsulotomy. Policy/Criteria I. It is the policy of health plans affiliated with Centene Corporation® (Centene) that YAG laser capsulotomy is medically necessary for the following indications: A. Posterior capsular opacification following cataract surgery resulting in best corrected visual acuity of 20/30 or worse associated with symptoms of blurred vision, visual distortion or glare affecting activities of daily living; B. Contraction of the posterior capsule with resulting displacement of the intraocular lens; C. Posterior capsular opacification resulting in best corrected visual acuity of 20/25 or worse, reducing the ability to evaluate and treat retinal detachment. Background YAG capsulotomy is the incision of an opaque posterior lens capsule in an aphakic or pseudophakic eye. This incision allows the capsule to retract and no longer serve as an obstruction to the passage of light through the media to the retina. The incision is performed with YAG laser. The eye examination must confirm the diagnosis of posterior capsular opacification and excludes other ocular causes of functional impairment by one of the following methods: The eye examination should demonstrate decreased light transmission (visual acuity worse than 20/30 or 20/25 if the procedure is performed to assist in the diagnosis and treatment of retinal detachment). Manifest refraction must be recorded with decrease in best-corrected visual acuity.

Optical Coherence Tomography for an In-Vivo Study of Posterior-Capsule
Hawlina et al. BMC Ophthalmology 2014, 14:131 http://www.biomedcentral.com/1471-2415/14/131 RESEARCH ARTICLE Open Access Optical coherence tomography for an in-vivo study of posterior-capsule-opacification types and their influence on the total-pulse energy required for Nd:YAG capsulotomy: a case series Gregor Hawlina1*, Darko Perovšek1, Brigita Drnovšek-Olup1, Janez Možina2 and Peter Gregorčič2 Abstract Background: Posterior capsule opacification (PCO) is the most common post-operative complication associated with cataract surgery and is mostly treated with Nd:YAG laser capsulotomy. Here, we demonstrate the use of high-resolution spectral-domain optical coherence tomography (OCT) as a technique for PCO analysis. Additionally, we evaluate the influence of PCO types and the distance between the intraocular lens (IOL) and the posterior capsule (PC), i.e., the IOL/PC distance, on the total-pulse energy required for the Nd:YAG laser posterior capsulotomy. Methods: 47 eyes with PCO scheduled for the Nd:YAG procedure were examined and divided into four categories: fibrosis, pearl, mixed type and late-postoperative capsular bag distension syndrome. Using custom-made computer software for OCT image analysis, the IOL/PC distances in two dimensions were measured. The IOL/PC distances were compared with those of a control group of 15 eyes without PCO. The influence of the different PCO types and the IOL/PC distance on the total-pulse energy required for the Nd:YAG procedure was analyzed. Results: The total-pulse energy required for a laser capsulotomy differs significantly between PCO types (p =0.005, Kruskal-Wallis test). The highest energy was required for the fibrosis PCO type, followed by mixed, pearl and late-postoperative capsular bag distension syndrome.
