20 | EYEWORLD DAILY NEWS | MAY 4, 2019 ASCRS NEWS ASCRS ASOA ANNUAL MEETING by Liz Hillman EyeWorld Senior Staff Writer exchange to treat refractive sur- prise, Dr. Trattler said it provides space for a wireless IOP sensor, low-vision intraocular telescopic assemblies, drug-delivery technol- ogy, and more. Juvene (LensGen) is a modu- lar IOL with a base lens and a cur- vature-changing lens that allows for "dynamic range of vision," said Sumit "Sam" Garg, MD, Irvine, California. This complex, he said, also fills the bag, prevent- ing a loss in capsular volume, and is a "complete IOL." Dr. Garg de- fined this as an IOL that provides presbyopia correction, contrast sensitivity, optical quality, closer emmetropia, astigmatism correc- tion, and upgrade ability. At this A fternoon sessions at OIS@ASCRS pre- sented innovations in postoperative adjusta- bility at the lens and the cornea. "Patients are asked to make a lifetime decision with concepts that are difficult to un- derstand in a matter of minutes," George Waring IV, MD, Mt. Pleasant, South Carolina, said of IOL decision making. Surgeons counsel patients on how they might do with various lenses, but in reality, "we're not quite sure how they're going to do," Dr. Waring said. He present- ed several studies that showed, de- spite several advances in available technologies, little more than 50% of patients fall within 0.5 D of intended target. Surgical options for post-cat- aract refractive errors include pig- gyback lenses, lens exchange, and LASIK and PRK. Newer options could prevent refractive surprises or handle them in a less invasive manner. Stephen Slade, MD, Hous- ton, discussed the Light Adjust- able Lens (RxSight). After stan- dard cataract surgery and after the patient has been refracted and trialed their prescription, this lens is adjusted with a light beam sever- al weeks postop. As Dr. Slade put it, would you buy the glasses you're going to wear after surgery before surgery? This is what current preoperative IOL power calculations do. The Light Adjustable Lens, however, decides upon the refraction after surgery. Perfect Lens has also created technology to offer postoperative adjustability. Steve Smathers, Irvine, California, said the device adjusts already implanted hydro- phobic and hydrophilic acrylic IOLs. It can alter sphere, cylinder, or both, and can add or remove multifocality. An in-office pro- cedure, it can potentially include multiple adjustments and doesn't involve cutting or tissue ablation. The basis of the change is photoinduced hydrolysis within the polymeric material initiated by femtosecond laser technology, Mr. Smathers said. Currently, he said investigators are making sure the technology doesn't create visual abnormalities and are identifying the right energy levels for human treatment, adjusting formulas to account for energy absorption from the cornea, bag, and aqueous humor. William Trattler, MD, Miami, discussed an implant that keeps the capsular bag open, reducing the chance of retinal de- tachment over time, allowing for safer IOL exchange, and providing space for other uses. The Gemini Refractive Capsule (Omega Ophthalmics) prevents capsular fibrosis with no cases of capsular opacity in the 50 implanted patients thus far, Dr. Trattler said. In addition to offering the opportunity for lens Postoperative adjustability at the lens and the cornea Dr. Garg presents on the Juvene IOL at OIS@ASCRS.
