Subbasal nerve regeneration after corneal surgery
79,00 € *
ggf. zzgl. Versand

Corneal damage caused by surgical procedures or trauma, results in the severing of corneal nerves and the subsequent reduction in corneal sensitivity. This in turn might compromise the blink response, induce dry eye symptoms, reduce tear flow and increase tear osmolarity. After surgery, subbasal corneal nerves regenerate which results in an improvement in corneal sensitivity. This book includes studies about subbasal nerve regeneration after corneal surgery (LASIK, LASEK, PTK and keratoplasty) using confocal microscopy, and the relationship between the degree of regeneration and recovery in corneal sensitivity and tear film functions. This book will be especially useful to ophthalmologists and eye disease researchers.

Pachymeter
39,00 € *
ggf. zzgl. Versand

High Quality Content by WIKIPEDIA articles! A pachymeter is a medical device used to measure the thickness of the eye's cornea. It is used to perform Corneal pachymetry prior to LASIK surgery, for Keratoconus screening, LRI surgery and is useful in screening for patients suspected of developing glaucoma among other uses. Modern devices use ultrasound technology , while earlier models were based on optical principles. The ultrasonic Pachymeters traditionally have been devices that provide the thickness of the human cornea in the form of a number in micrometres that is displayed to the user.

Corneal pachymetry

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Corneal pachymetry is the process of measuring the thickness of the cornea using contact methods, such as ultrasound and confocal microscopy (CONFOSCAN), or noncontact methods such as optical biometry with a single Scheimpflug camera (such as SIRIUS or PENTACAM), or a Dual Scheimpflug camera (such as GALILEI), or Optical Coherence Tomography (OCT, such as Visante) and online Optical Coherence Pachymetry (OCP, such as ORBSCAN). Corneal Pachymetry is particularly essential prior to a LASIK procedure for ensuring sufficient corneal thickness to prevent abnormal bulging out of the cornea, a side effect known as ectasia.

Effect of Trans PRK on Tear Film stability
39,90 € *
ggf. zzgl. Versand

Trans PRK is a type of refractive surgery that can correct vision problems and eliminate the need for glass or contact lenses. It's fast-even faster than LASIK. Dr. Katzman said it takes less than five minutes per eye. The procedure itself is also easier to tolerate/less painful than LASIK. Results are long-lasting. One Trans PRK treatment may be all you need for your lifetime, depending on how old you are at your first treatment. Some people need a follow-up "enhancement" procedure, but oftentimes it's needed in only one of the eyes. It's an effective option for anyone who isn't an ideal candidate for LASIK surgery or other refractive eye procedures. Unlike LASIK, there's no risk of corneal flap complications (because there is no flap).

Corneal Collagen Cross Linking
117,67 € *
ggf. zzgl. Versand

This book provides comprehensive coverage of corneal collagen cross-linking (CXL), a major management modality for keratoconus and ectatic corneal disorders. All aspects are covered, including refractive and non-refractive surgery indications, models of application, safety, efficacy, performance, outcome measures, evidence of CXL, complications, contraindications, use in children, and controversies. The discussion reflects the considerable progress that has been made in understanding of the modality since its development in the late 1990s. Detailed attention is paid to new concepts, changing surgical techniques and indications, the latest evidence-based science and research, and the future of CXL. Guidance is also provided on the use of CXL in combination with other modalities, such as LASIK, PRK, intracorneal ring implantation and others. The text is accompanied by numerous high-quality color illustrations. Corneal Collagen Cross Linking will provide the reader with a sound grasp of the technique and its use and will hopefully also serve as a stimulus to further research and advances.

Femtosecond Laser Surgery in Ophthalmology
134,99 € *
ggf. zzgl. Versand

The femtosecond laser has emerged as a groundbreaking game-changer in ophthalmic surgery. It was first introduced for corneal refractive surgery in flap creation during LASIK, and subsequently for cataract surgery in 2008. The femtosecond laser cuts deeply on a single plane without collateral damage. Its high precision and safety result in excellent outcomes in the hands of experienced eye surgeons, benefiting virtually everyone.Femtosecond Laser Surgery in Ophthalmology fills an unmet need for a comprehensive, up-to-date resource on growing applications of this state-of-the-art technology. H Burkhard Dick is a world-renowned pioneer who has performed more than 6,000 laser cataract operations. Readers will benefit from his keen insights along with the collective expertise of co-authors Tim Schultz, Ronald D. Gerste, and a cadre of top-notch contributors. Twenty-nine chapters encompass basic physics, refractive and therapeutic cornea treatment, various aspects of laser cataract surgery, and patient selection.Key FeaturesClinical pearls, outcomes, and complications management in femtosecond laser-assisted in situkeratomileusis surgeryDiscussion of crucial steps including capsulotomy, lens fragmentation, and corneal incisionsThe use of the femtosecond laser for presbyopia, pediatric cataract surgery, and ocular comorbiditiesExtensive videos posted in the Thieme MediaCenter further elucidate techniquesMore than 300 high quality illustrations and photos add a rich visual dimensionThis practical book provides in-depth knowledge on the applications of femtosecond laser surgery, enabling cataract and refractive surgeons to incorporate these techniques into daily practice.

Optimizing Suboptimal Results Following Catarac...
105,77 € *
ggf. zzgl. Versand

A concise review and comprehensive guide to improving cataract surgery outcomesSignificant advances have been made in refractive surgery in the last decade. Eye surgeons today can leverage many cutting-edge intraocular lens (IOL) technologies such as multifocal, extended depth of field, toric, accommodating, and aspheric. Concurrent innovations including optics, phacoemulsification, superior keratometry and biometry, and posterior cornea evaluation have resulted in improved cataract surgery outcomes. Recent advances in the diagnosis and treatment of cataracts have dramatically improved patient satisfaction following cataract surgery, yet common and rare complications still occur such as dry eye, endophthalmitis, and retinal detachment. Furthermore, only 80% of cataract surgery procedures bring patients to within 0.5 diopters of their needed refraction.Optimizing Suboptimal Results Following Cataract Surgery: Refractive and Non-Refractive Management presents the latest techniques for achieving optimal results and overcoming complications in cataract surgery. Internationally renowned ophthalmic surgery pioneers Priya Narang and William Trattler have created an unparalleled guide to overcoming complex cases and residual refractive errors. The book starts with six chapters on suboptimal causes and considerations, followed by dedicated sections covering refractive and non-refractive enhancements. The fourth section features chapters on keratoconus, cystoid macular edema, endophthalmitis, toxic anterior segment syndrome, and vitritis, as well as intraoperative aberrometry, futuristic approaches and advancements, and telescopic IOLs.Key HighlightsRefractive enhancement procedures including corneal-based procedures such as astigmatic keratotomy, LASIK, PRK, and SMILE, IOL exchange, piggyback IOL, toric IOL, and premium IOLs and associated problemsNonrefractive enhancement procedures including dysphotopsias and surgical management, bullous keratopathy and endothelial keratoplasty, complex IOL issues such as malpositioned IOL and capsular bag, and posterior capsular rupture and IOL lens implantationPractical tips and steps to prevent and manage undesired outcomes30 surgical videos posted online highlight a diverse array of complex cases and technical advances to help prevent suboptimal resultsOphthalmologists, ophthalmology residents, fellows, and subspecialists will greatly benefit from the significant pearls and knowledge presented in this indispensable cataract surgery resource.
