Some say progress is impossible in Washington D.C. The American Society of Cataract and Refractive Surgery meeting here in May proved otherwise. Several companies introduced nifty new improvements that should make cataract and MIGS glaucoma surgery better and easier. Following a tour of the floor with eye surgeons Ahad Mahootchi, MD, of The Eye Clinic of Florida in Zephyrillis, Fla., and William J. Lahners, MD, FACS, of the Center for Sight in Sarasota, Fla., here's a report on what we saw. OSM

A new monofocal IOL

With all the technological advances in torics and multifocals, monofocal IOLs haven't received much attention lately. Bausch & Lomb is hoping that will change with the enVista monofocal IOL. The company claims its new lens enjoys several advantages over competing products:

  • The lens incorporates what the company calls "advanced, aberration-free optics," with uniform power throughout. Clinically, the company says that means better visual results. The lens performs well even if it's decentered, and it provides excellent depth of field, image quality and contrast sensitivity.
  • The company says there are no "glistenings" or edge glare, complications that have occurred with other IOLs.
  • The material is 16 times harder than traditional hydrophobic IOLs, making it hard to scratch.
  • The haptics provide exceptional contact with the capsular bag, promising superior stability.

"I'm in a small town. If something is going to go wrong with an IOL 15 years from now, that's a big, big deal to me," says Dr. Mahootchi. He likes the enVista lens material for that reason — it's stable, and in the unlikely event that a patient requires an air or gas bubble for a retinal procedure, the lens doesn't opacify. "I recommend it for my neighbors," says Dr. Mahootchi. "Previously, the disadvantage was that it unfolds a little slowly. Now it unfolds much quicker."

Iris Speculum
Diamatrix's X1 Ready-Loaded Iris Speculum.

Pupillary dilation and maintenance

X1 Ready-Loaded Iris Speculum. Diamatrix launched its X1 Ready-Loaded Iris Speculum, so named because it comes prepackaged in an injector. To use it, the surgeon injects the ring, engaging the leading hook into the distal iris. As the speculum emerges from the injector, the surgeon watches to make sure the lateral hooks engage on both sides. The surgeon leaves the last hook on top of the proximal iris and then engages it using an instrument called the Williamson hook. Dr. Mahootchi did some practice maneuvers with the device, liked it and plans to soon try it.

Diamatrix President Ron Dykes, who invented the device, says the ring creates the widest opening of any device on the market and says it's very gentle on the iris. The ring opens the pupil to 6.7 mm. The 4 "cradles" are said not to pinch the iris margin, so you can actually rotate the speculum in the eye without rubbing off pigment. The devices come 4 to a box.
