53 EW REFRACTIVE SURGERY August 2015 Devgan: devgan@gmail.com Thompson: vance.thompson@vancethompsonvision.com Yoo: syoo@med.miami.edu quality. PRK can be such a beautiful enhancer in these situations to treat both the residual refractive error and improve the best corrected and uncorrected image quality," Dr. Thompson said. Dr. Devgan said for the occa- sional user, "don't worry about do- ing a 'custom' treatment or a 'wave scan' reading—the actual refraction that makes the patient happy is more important." Before the initial surgery, Dr. Devgan recommends choosing a higher power IOL if in doubt since myopic ablations are more accurate than hyperopic ablations. Open-access? Roll-on/roll-off options? Occasional-use surgeons might consider buying a used laser, but the service contracts will still equate to around $30,000–$50,000 a year. Partnering also makes sense, as the refractive expert is likely to offer his/ her services at a deep discount, Dr. Devgan said. In Beverly Hills, one open access facility serves 30 dif- ferent ophthalmologists, who book time accordingly, he said. One last caveat: Surgeons must be certified before using a laser, so novice users should plan on having 4–6 eyes that need enhancements on the day of training, Dr. Devgan said. Open-access is a good option for surgeons who laser infrequently, Dr. Yoo said. "The costs of owning and maintaining a laser can be defrayed while still being able to provide the service to your patients." Most refractive surgeons or re- fractive centers "would welcome an open-access surgeon who wants to use their laser occasionally for a fee- per-case," Dr. Dell said. "It adds to their bottom line, and there are very few laser vision correction centers that are doing the volume that they would like to do right now." If surgeons are at a point where volume is dictating "perhaps dozens of cases a month or maybe 15 to 20 cases a month, those practices might consider a mobile, roll-on/roll-off laser," Dr. Dell said, and several companies offer that option.
