Mr Richard Packard explores the Efficacy & Safety profile of CAPSULaser as he shares the “CAPSULaser CE Study Overview”. In this presentation, Mr Packard concludes that the accuracy of diameter, circularity and centration is superior to the manual capsulotomy control group and that these results indicate that the selective laser capsulotomy performed by CAPSULaser may […]
Dr Pavel Stodulka was the first ophthalmologist in the world to use CAPSULaser and has been involved from the beginning in both the clinical use and the ongoing development of this Selective Laser Capsulotomy (SLC) technology. In this presentation Pavel presents his experience and gives some early insights to the importance of automated capsulotomy in […]
Mr Sheraz Daya presents “Parameters Effecting Capsulotomy” comparing the elasticity and fracture strength of manual CCC, femtosecond laser and selective laser capsulotomies (SLC). The data presented by Mr Daya is part of a study performed by Professor Soon Phaik Chee at the Singapore National Eye Centre and in collaboration with Mr Richard Packard, Arnott Eye […]
Los Gatos, CA – EXCEL-LENS, Inc. presents the CAPSULaser ESCRS symposium highlights in a 6 part series to be released weekly Part 1 released today – The Introduction presented by Professor Burkhard Dick focuses on “From Capsulorhexis to Capsulotomy – Why CAPSULaser?” Part 2 to be released 8th November – Mr Sheraz Daya shares “Parameters […]
Latest clinical data for CAPSULaser was shared by Mr Richard Packard during AECOS on Saturday 2nd June. Mr Packard’s Presentation highlights: 125 patient, prospective, controlled randomized clinical trial for CAPSULaser vs Manual capsulotomies Safety, Efficacy & Accuracy demonstrated for CAPSULaser 86% of capsulotomy diameter within 0.1mm of target vs 44% in the Manual group (p<0.0001) CAPSULaser […]
CAPSULASER showcased in the “Exciting New Devices That Will Help You” educational event moderated by Robert H. Osher, MD during ASCRS Washington April 13 – 17 Mr Richard Packard, MD, DO, FRCS, FRCOphth had a busy ASCRS for CAPSULaser, firstly presenting impressive sizing, circularity and centration data for CAPSULaser in the Industry Spotlight Theatre. Mr Packard […]
A selective target for CAPSULaser is created when the capsule is stained with CAPSULBlue, a specific formulation of trypan blue. A fixation laser, coaxial with the view of the surgeon, allows identification of the visual axis location in patients with translucent cataracts in a manner similar to LASIK. In addition, the capsulotomy position is visualized […]
The capsulotomy range can be selected from 4.0 to 5.5 mm in 0.1 mm increments.
Our surgeon advisors recommend that the pupil be at least 1mm greater than the selected capsulotomy diameter. A smaller capsulotomy may be utilized if appropriate but try pharmacological dilation first. If a small degree of dilation is required, CAPSULVisc 2% can be used to expand the pupil diameter mechanically. If the pupil is constricted the […]
Miosis was not observed in any of the clinical studies.
In preclinical studies, where the iris was intentionally targeted to determine the consequences of an inadvertent laser interaction, the following reaction was documented: Only superficial discoloration of the iris No bleeding No cutting or tearing No distortion No miosis
CAPSULaser will not interact with transparent tissue. The capsule needs to be stained with a dye to provide the selective target which only CAPSULBlue provides. The CAPSULaser technique requires two simultaneous conditions to create a capsulotomy: first a CAPSULBlue stained capsule, and second, the treatment laser focused on the capsule.
No, it is a continuous-wave laser that is always on during the selective laser capsulotomy treatment. It is not a pulsed laser like the femtosecond laser.
There are many differences between CAPSULaser and FLACS. Surgical benefits: The visual axis can be directly identified in surgery for the majority of patients with CAPSULaser. CAPSULVisc is utilized with CAPSULaser providing the additional safety associated with an OVD filled anterior chamber. The overall surgery time is less for CAPSULaser. The laser energy applied to […]
The laser wavelength is at the peak spectral absorption for CAPSULBlue. The wavelength is in the orange-red range of the spectrum.
CAPSULBlue is optimized for consistent staining of the anterior capsule and for absorption of the wavelength of CAPSULaser. This leads to consistent capsulotomies. It is the only version of trypan blue that has been formulated for selective laser capsulotomy.
For cataract surgery trypan blue selectively stains the lens capsule and non-living cells. Healthy corneal endothelial cells are not stained in vivo, as the cellular membrane naturally prevents dye absorption from the posterior surface. Corneal surgical techniques, such as DSEK, are different and the donor tissue can be stained with dye through in vitro application […]
SEM (scanning electron microscopy) images show that the capsule with a “rolled-over” edge, consequently the two layers of tissue at the rim present a darker blue color. This enhances visualization for the remaining steps of the cataract procedure.
The “rolled-over” characteristic of the edge created by CAPSULaser generates a strong capsulotomy that is resistant to tearing. Preclinical studies on human cadaver eyes at SERI (Singapore Eye Research Institute) have demonstrated that the capsulotomy rim strength is at least equivalent to manual and FLACS. The mechanism of action of the laser on the capsule […]
In surgery over 90% of the CAPSULBlue is removed by rinsing unabsorbed dye and extraction of the stained capsular disk during surgery. The remaining trypan blue (CAPSULBlue) washes out of the eye naturally within a few hours following surgery. On a global basis, trypan blue is used in over 10% of cataract surgeries for complex […]
At 12 months and longer-term follow-up, fibrosis has not been observed.
The high optical quality of CAPSULVisc sodium hyaluronate enhances the performance of CAPSULaser and is proven to deliver consistent outcomes. CAPSULVisc protects the endothelium for both the capsulotomy and the phaco procedure. CAPSULVisc is available in 2% NaHy which is cohesive, and 3% NaHy which is dispersive. CAPSULVisc remains in the anterior chamber during surgery to […]
Yes, during clinical evaluation hyper-mature cataracts were treated whilst avoiding anterior tears. The use of CAPSULVisc balances the pressure in the intumescent capsule and provides a stable anterior chamber for the laser to act.
