Abstract:
Overview

The ophthalmic community has recently celebrated 50 years of phacoemulsification innovation, and the technology continues to evolve. Recent advances in phacoemulsification techniques and technology have improved surgical outcomes and reduced complications pre and post cataract surgery. However, opinions vary as to which techniques offer the best outcome. In an expert interview, Jennifer Loh, a board-certified ophthalmologist practicing in the south Florida area with considerable expertise in cataract surgery, discussed the most exciting developments and current controversies in phacoemulsification technology.

The ophthalmic community has recently celebrated 50 years of phacoemulsification innovation, and the technology continues to evolve. Recent advances in phacoemulsification techniques and technology have improved surgical outcomes and reduced complications pre and post cataract surgery. However, opinions vary as to which techniques offer the best outcome. In an expert interview, Jennifer Loh, a board-certified ophthalmologist practicing in the south Florida area with considerable expertise in cataract surgery, discussed the most exciting developments and current controversies in phacoemulsification technology.

Q. What are the major unmet needs in current phacoemulsification procedures?

One of the hottest and most controversial topics in cataract surgery right now is the issue of intracameral antibiotics that can be given at the time of surgery. While multiple studies1,2 have proven that intracameral antibiotics are effective at reducing the incidence of endophthalmitis, in the US, there is still no Food and Drug Administration (FDA)-approved intracameral antibiotic. And while there are many compounded versions available, this still comes at a risk for problems such as toxic anterior segment syndrome (TASS) or dilution error.

Q. What were the most exciting developments in phacoemulsification technology in 2017?

One of the most exciting new technologies in 2017 was the advent of miLOOPTM (Iantech, Inc., Reno, NV, US). MiLoop is a new microsurgical device that uses a nitinol wire loop (the same material that is used in cardiac catheterizations) to dissect the cataract into multiple pieces, while it is still in the capsular bag. This allows for safe disassembly of the cataract with less phacoemulsification energy. It is especially useful with the dense, "leathery" type cataracts that are still very common today in the US and further afield.

Q. What are the advantages of the fluidics of the comprehensive phaco systems available in the US?

The phaco systems in the US today provide very stable chambers during cataract surgery. We have options for systems including venturi, peristaltic and combination systems today. I have worked with both the Stellaris® (Bausch & Lomb, Bridgewater, NJ, US) and Centurion® (Alcon, Fort Worth, TX, US) systems and find them both excellent.

Q. What emerging technologies appear promising?

I am very interested in the new hypersonic vitrectomy system, VitesseTM by Bausch and Lomb (Bridgewater, NJ, US). Instead of the traditional guillotine cutting system of current vitrectomy systems, the Vitesse liquifies the vitreous using an open port. This technique prevents the vitrector from pulling on the vitreous and causing retinal traction. While most cataract surgeons are luckily not routinely performing vitrectomies, I think having access to this great technology could help improve our results when complications do occur.

Q. For which patients is femtosecond laser technology most useful?

Femtosecond laser technology is most useful for patients receiving an advanced technology intraocular lens (toric, extra depth of focus, multifocal) and for patients with dense nuclear cataracts. The automatic, well-centered capsulotomy helps with precise lens centration, which can help with the refractive outcome.
