VisuMax®femtosecond laser for corneal refractive surgery

2008

Femtosecond lasers are increasingly present in ophthalmologic surgical theaters for a variety of reasons. These include faster and better visual outcomes, increased accuracy and predictability for corneal flap thickness in laser in situ keratomileusis procedures. Recent applications of modern femtosecond lasers have broadened the range of uses: keratoplasty, intrastromal segment insertion and even glaucoma and presbyopia surgery. This device profile provides an overview of the advantages of femtosecond lasers in ophthalmic surgery, paying special attention to the new VisuMax® femtosecond laser from Zeiss/Meditec.

Zur Wirkung von Muskelrelaxantien auf den intraokularen Druck

1988

Since general anesthesia is being used increasingly in ophthalmic surgery, the effects of anesthetic drugs on intraocular pressure (IOP) have to be considered. Competitive neuromuscular blocking drugs either do not affect IOP or produce a slight decrease. Depolarizing muscle relaxants increase IOP. This effect, which is pronounced with succinylcholine, cannot be reliably prevented by any concomitant medication. The new competitive relaxants atracurium and vecuronium provide stable conditions with respect to IOP and systemic circulation, combined with fast onset and intermediate duration of action.

Application principles of excimer lasers in ophthalmology

2010

Abstract Excimer lasers (193 nm) can be used for photoablation of the human cornea due to their specific physical characteristics. This laser is applied in corneal refractive surgery for the targeted removal of corneal tissue for the purpose of correcting refractive errors. This article provides a short overview of the scientific development of excimer lasers for use in ophthalmic surgery and of the range of applications of these tools.
