This transformation willtake time, but it will be measured in months andyears rather than decades. In the near term, theprocedure will complement rather than replacephacoemulsification, attracting the interest ofmanufacturers and surgeons alike. The pace of technological innovation is muchfaster today than it was in the 1970s and 1980s. Ittook more than 7 years for the first 10 million per-sonal computers, introduced in 1975, to be sold.Launched in 2010, Apple’s iPad achieved this samefeat in less than 9 months. The adoption rate forFacebook and Twitter has been huge, and Grouponhas emerged as the fastest-growing Internet com-merce site. These mainstream consumer experi-ences shape opinion and foster more rapid adop-tion across the spectrum of technological innova-tion, including what eye surgeons have to offer. Consumer trends, as well as ophthalmology’sown experience with elective procedures, stronglysuggest that surgeons should get involved. Thequestion is, when? Now is the right time to beginthinking and planning, as manufacturers arebuilding their capacity to deliver the devices.Eventually, this technology will make its way intoeveryone’s community. There are still many ques-tions, such as which laser platform is the best,how much will it cost, where will the surgery beperformed, which patients qualify, and how muchshould patients be charged? This is an emergingfield; answers will become clear in the comingmonths, and they will evolve as we learn moreabout how best to integrate this technology intothe practice. The earliest customers will pave theway, and their experiences will help all interestedsurgeons plan accordingly. ■ Shareef Mahdavi is president of SM2Strategic and advises numerous oph-thalmic companies, including Alcon,Laboratories, Inc., Bausch + Lomb, andWaveTec Vision.
