What separates this system from the pack is that its ablation speed is running at 500Hz. One of the many advantages of the new EX500 is its speed. For instance, if you become concerned about the amount of tissue that the laser will have to remove, you can switch from an 8-mm to a 6-mm optical zone.”. Eye tracker. Though our cross-linking studies in the U.S. can only cross-link the patient, in Europe they’re also able to use the laser to correct refractive errors at the same time as the cross-linking.”. With 500 Hz, though, it’s speed is 1.4 seconds per diopter.” Dr. Stonecipher says it’s been his experience that up to about -7 D, the outcomes between the 400-Hz and the 500-Hz lasers are somewhat similar. Our team at Laser Eye Center believes that the EX500 is the gold standard of … It is quick and simple to use and correlates with preoperative Pentacam pachymetry and postoperative optical coherence tomography flap thickness measurements. It is key to the smooth use of the laser, especially if it is used in conjunction with the FS200. Thinking about getting PRK done. The eye tracker runs at 1,050 Hz and has a latency time of 2 milliseconds, tracks pupils from 1.5 to 8 mm and is able to compensate for cyclotorsion. A Closer Look at the New EX500 Laser The new excimer from Alcon/WaveLight has features to enhance connectivity and decrease procedure times. WaveLight EX500 Excimer Laser. The eye tracker is also motorized, no longer swinging over the patient’s chest but dropping from within the laser bridge over the eye. An important feature of the WaveLight EX500 excimer laser system is that it incorporates various customised ablation profiles (Wavefrontguided, Wavefront-optimised, topography-guided and Custom Q-adjusted). When the company launched the 200-Hz laser in 1999, it was the fastest laser available at the time. “The most interesting thing about the new device, in my opinion, is the connectivity features,” Dr. Stonecipher says. One of the most common approaches to refractive correction is laser vision correction. A simulated eye composed of resins and other materials can help beginning surgeons hone their techniques. The FDA has approved several excimer lasers for use in vision correction surgery. The surgeon then lifts the flap and applies a laser treatment to reshape the eye to correct vision. Dr. Cummings may be reached at tel: +353 1 2930470; fax: +353 1 2935978; e-mail: abc@wellingtoneyeclinic. From intrastromal correction to surface ablation to lens-based strategies, the aim of these techniques is to provide patients with a better refractive status and, in as many cases as possible, spectacle independence. To aid in decision making, the ablation profiles that are being considered for a treatment can be compared on the same screen. Patient Financing. With a repetition rate of 500 pulses per second, the EX500 is the fastest on the US market today. This product integrates cutting edge technology to ensure faster, safer, and more reliable treatment. Contoura Vision is performed with Alcon’s WaveLight Allegretto Wave Eye-Q or WaveLight EX500 Excimer LaserSystems, in conjunction with the WaveLight Topolyzer Vario Diagnostic Device. He states that he is a consultant to and clinical investigator for Alcon/WaveLight. Arthur B. Cummings, MB ChB, FCS(SA), MMed (Ophth), FRCS(Edin), practices at the Wellington Eye Clinic & UPMC Beacon Hospital, Dublin, Ireland. “We found that the faster 400-Hz results were better, especially with the higher minuses,” says Dr. Stonecipher. Schedule a Consultation To schedule an appointment, call 704-540-9595 or complete the short form below. Additional pulses are sent to the periphery to compensate for energy loss. ALCON WaveLight EX500 Laser - Excimer. To be sure to track the eye accurately, the EX500’s tracking system is composed of four lights situated in positions similar to the corners of a rectangle, with a fifth fixation light placed in the middle of the rectangle. The laser is economical with corneal tissue. A myopia treatment at a 6-mm optical zone takes 1.4 seconds per diopter, and at a 6.5-mm optical zone (my default diameter) it takes 1.9 seconds per diopter. I have done comparative studies of the refractive outcomes after laser vision correction with the 400 Eye-Q and EX500 laser platforms. With the EX500, a myopia treatment at a 6-mm optical zone takes 1.4 seconds per diopter; at a 6.5-mm optical zone it takes 1.9 seconds per diopter. Though they’re not approved in the United States, there are features of the EX500 that are available elsewhere in the world that increase its functionality in various situations. In the 400-Hz group, 98.5 percent (64/65) and 100 percent (65/65) of eyes were within ±0.50 D of the intended correction at three and six months postoperatively. However impressive its speed, this is by no means the laser’s overriding feature. For comparison sake, the previous model ran at 400 Hz. Some devices run at eight to 10 seconds per diopter, so this can be five times faster.”. The FDA has approved several excimer lasers for use in vision correction surgery. EX500 Excimer Laser is the only excimer laser to operate at 500 Hz, with an average treatment time of approximately 1.4 seconds per diopter1. The Allegretto Wave was developed specifically for wavefront treatments—with a fast, accurate tracker, a small 0.95-mm spot size, a rapid 200-Hz repetition rate, and a Gaussian beam profile that is particularly well-suited to treating localized aberrations. The standard ablation profile for both platforms is wavefrontoptimized, which is what we use for 85% of our primary procedures. There are multiple other features on the laser platform, but I will discuss only those that I am very familiar with and use on a regular basis: Online optical pachymetry. Moderately high myopic eyes (6.0 to <8.0 D [6 D]) were compared with high myopic eyes (8.0 D or greater [8 D]). The faster laser reduces the incidence of corneal dehydration during the procedure, which reduces overcorrections. Optical low-coherence reflectometry (WaveLight EX500) was used to measure central corneal thickness prior to lifting the flap, and the residual stromal bed immediately after excimer ablation. At the six-month follow-up, Dr. Stonecipher and his colleagues found that refractive predictability and visual acuity were statistically significantly superior in eyes in the 400-Hz group (p<0.01). The WaveLight EX500 excimer laser (Alcon Laboratories, Inc.) is the latest in a line of very fast flying spot lasers to come from the WaveLight stable. You may have heard of traditional or standard LASIK compared to “all-laser” or “bladeless” LASIK. Watch Queue Queue. Request An Appointment. “In some other systems, if your nomogram called for 2.21 D of correction, you could do a 2-D treatment or a 2.25-D treatment. “Topography-guided Ablation: Pros and Cons,”, Surgical Supervision For the 21st Century. Thanks for visiting CRSTEurope. This greatly increases efficiency and safety and reduces input errors, as it eliminates multiple input entries on the different devices.
