MORIA CORNEAL AND REFRACTIVE SURGERY
I-MED Pharma is the exclusive distributor for MORIA in Canada. With a decade and a half of collaboration, we have unmatched expertise and exprience in the Canadian corneal surgery market.
For nearly two centuries, MORIA instruments have been involved in ophthalmic surgeries all over the world. MORIA innovations have accompanied major developments in eye surgery: the advent of microsurgery in the seventies, phacoemulsification ten years later and, more recently, refractive surgery or new corneal transplant techniques. Working closely with surgeons, MORIA has developed innovative and worldwide renowned, quality instruments.
I-MED Pharma distributes cutting-edge equipment for: Epi-LASIK, LASIK and Lamellar Keratoplasty.
Since its creation, surface ablation has played an important role in refractive surgery. Although LASIK is the procedure of choice for most patients worldwide, there are limitations to it. Nowadays, thanks to different options (LASIK, IntraLASIK, and Epi-LASIK), the refractive surgeon can propose a true customization to the patients, based on corneal status, work and leisure activities, and risk tolerance. This why in numerous comprehensive refractive practices around the globe today, roughly 80-85% of the procedures performed are LASIK, and 15-20% are surface ablations. The standard surface ablation techniques, essentially PRK and LASEK, have well-known drawbacks. They are associated with important pain, and slow visual recovery and in both cases, the introduction of alcohol can be traumatic to the eye.
Epi-LASIK combines the best of LASIK and surface ablation. This refractive surgical technique consists in mechanically cleaving the epithelium from the Bowman’s membrane leaving a pristine optical zone for laser ablation thanks to a device called an epikeratome. Epi-LASIK preserves the structural integrity of the eye and allows the production of a remarkably viable epithelial flap. This flap can be either discarded or repositioned, according to the surgeon’s preference. Epi-LASIK also minimizes discomfort, and shortens the length of visual recovery.
LASIK is a refractive surgery performed by ophthalmologists to correct refractive defects. Many patients choose LASIK as an alternative of wearing corrective eyeglasses or contact lenses, that’s why it has become the most commonly performed refractive surgery procedure.
With nearsighted people, the goal is to flatten the too-steep cornea. With farsighted people, a steeper cornea is desired. Astigmatism is corrected by smoothing an irregular cornea into a more normal shape. To remove the corneal tissue and reshape the cornea, the surgeon uses an excimer laser.
Why is LASIK so popular? Because there is a relative lack of pain afterward and good vision is usually achieved by the very next day. More than 17 million people worldwide have had LASIK or other laser refractive surgery. The number of laser vision correction procedures performed annually in the United States has remained relatively unchanged: approximately 1.3 million procedures were performed each year in 2004, 2005 and 2006, and it was estimated that another 1.3 million would be performed in 2007 (TLC Vision Corp. 2006 Annual Report).
MORIA, the undisputed leader in disposable microkeratome technology, offers two different mechanical and automated microkeratomes for LASIK surgery: the M2 Single-Use and the One Use-Plus SBK:
Descemet’s Stripping Automated Endothelial Keratoplasty (DSAEK) is a posterior corneal transplantation technique that replaces dysfunctional recipient endothelium with healthy donor tissue while sparing the entire recipient stroma. DSAEK is currently recognized as the “state-of-the-art” in the endothelial keratoplasty field.
Dr. Melles first described the surgical technique for posterior lamellar keratoplasty, in 1998. Then in 2001, Dr. Terry adopted this technique in the United States and renamed the procedure DLEK (Deep Lamellar Endothelial Keratoplasty). In 2004, Dr. Melles described a technique in which he simply stripped Descemet’s membrane from the recipient and thus convert.
Technology behind MORIA
Evolution 3E: A Common Technology Platform for All Surgeries
MORIA’ s computerized console offers a wealth of features to enhance performance, safety, flexibility, and ease-to-use:
MORIA Vacuum Trephines & Corneal Vacuum Punches
The Single-Use Adjustable Vacuum Trephine – Designed to produce straight-walled cuts, the adjustable trephine features an adjustements ring enabling setting the blade descent depth. Its centration indicator ensures no parallax errors. Moreover, its vacuum surface is 3 times more efficient than a standard trephine and its limbal suction features a central corneal support design for a perfect conformation to the cornea.
