A Comparison of Different Operating Systems for Femtosecond Lasers in Cataract Surgery
Journal of Ophthalmology, Volume 2015, Issue 1, 2015., 2015 The introduction of femtosecond lasers is potentially a major shift in the way we approach cataract surgery. The development of increasingly sophisticated intraocular lenses (IOLs), coupled with heightened patient expectation of high quality postsurgical visual outcomes, has generated the need for a more precise, highly reproducible and standardized ...

Sustainability in Cataract and Refractive Surgery: Current Challenges and Future Perspectives
Journal of Ophthalmology, Volume 2025, Issue 1, 2025.Cataract and refractive surgery are integral to improving vision health and quality of life; however, their growing environmental impact poses significant concerns. These procedures contribute notably to medical waste, excessive energy consumption, and pharmaceutical overuse, amplifying the carbon footprint of health care.

A Fully Differential Digital CMOS Pulse UWB Generator [PDF]
, 2009 A new fully-digital CMOS pulse generator for impulse-radio Ultra-Wide-Band (UWB) systems is presented. First, the shape of the pulse which best fits the FCC regulation in the 3.1-5 GHz sub-band of the entire 3.1-10.6 GHz UWB bandwidth is derived and ...

The Physics of Postless Hip Arthroscopy
Arthroscopy Techniques, Volume 13, Issue 10, October 2024.Abstract Hip arthroscopy is commonly performed to treat femoroacetabular impingement syndrome. A post‐assisted arthroscopic hip preservation surgery approach provides joint distraction for central‐compartment access. Owing to the location, compression of the post in the perineum may cause injuries to the pudendal nerve, perineal soft tissue, or ...

Ultrawideband pulse correlation and distance error estimation [PDF]
, 2010 In a given number of wireless systems, and ultrawideband (UWB) in particular, a way to communicate between transceivers is by correlating received pulses with one or several reference-pulse templates.

A Robotic Diathermy System for Automated Capsulotomy
, 2018 Background: Cataracts are the leading cause of blindness and are treated surgically. Capsulotomy describes the opening of the lens capsule during this surgery and is most commonly performed by manual tearing, thermal cutting, or laser ablation.

Pulse pedestal suppression using four-wave mixing in an SOA [PDF]
, 2008 Experimental results are presented demonstrating how four-wave mixing in a semiconductor optical amplifier can be used to remove pulse pedestals introduced due to nonlinearities which occur upon pulse propagation in an optical system.
