SAN DIEGO — New developments in intraocular lenses have led to the expansion of the number of patients who could benefit from them, experts report.
Only 0.2% of Americans with presbyopia have intraocular lenses. That’s just 280,000 of the 187.8 million patients who might benefit from the lenses, said Daniel Durrie, MD, from Overland Park, Kansas. “Our system is missing 99.8% of the potential market,” he pointed out.
Dr Durrie took part in a seminar on new technology in intraocular lenses here at the American Society of Cataract and Refractive Surgery 2015 Symposium.
To take advantage of the potential market of people 45 to 64 years of age, ophthalmologists should brand themselves as “dysfunctional lens surgeons,” capable of treating a spectrum of poor vision that begins with presbyopia and continues into cataracts, Dr Durrie explained.
“I feel that we have this huge wave coming. The market is huge and it’s growing, and industry is starting to develop technology,” he said.
Multifocal intraocular lenses are an option for patients who want good visual acuity at a full range of distances, said Rex Hamilton, MD, from the University of California at Los Angeles, during the seminar.
Multifocal Lenses
One reason that the multifocal lenses have not caught on yet is that the versions created in the 1990s and early 2000s were disappointing, and sometimes left the patients with halos and poor intermediate vision, Dr Hamilton explained.
Originally, the lenses were not well designed for patients with large pupil sizes, he said, but newer versions of multifocal intraocular lenses have partially addressed this problem.
“The new multifocal lenses are great,” he said. “But we still have to set expectations appropriately to avoid disappointment.”
Dr Hamilton said he advises surgeons who are implanting multifocal lenses to measure pupil size. “I think it will allow us to appropriately counsel the patient.”……
