C O N T A C T L E N S S P E C T R U M S P E C I A L E D I T I O N 2 0 1 7 c l s p e c t r u m . c o m 20 had a history of ocular toxoca- riasis at age 4 and was self-con- scious because of the difference in the appearance of her two eyes. Note the much more nat- ural appearance of her eye after being fitted with a cosmetic tinted lens. SUMMARY All that's left is to build a close relationship with your contact lens laboratory (in particular, their expert consultants), start attending training sessions offered by associations and at major meetings, and begin to build your internal and external referral network. You will be well on your way to establishing your practice as a Specialty Contact Lens Center of Excellence. CLS PRACTICE BUILDING 10. UNDERSTAND THE ROLE OF TINTED LENSES FOR MEDICAL INDICATIONS Contact lens specialists may encounter patients who need specially tinted lenses for various reasons, includ- ing cosmetic correction, artificial pupil, matching the fellow eye's iris pigmentation, and so on. The use of these lenses is a life-changing event for patients. Pre- scribing tinted lenses requires in-office diagnostic sets, color swatches, or digital photography to determine the best possible color match.

Patient with anisocoria, leukocoria, and iris heterochromia; B. Corrected with cosmetic tinted lens. A B RESEARCH REVIEW continued from p.7 long-term, daytime scleral wear upon re-epithelialization. All eight eyes exhibited resolution of the persistent epithelial defect. No eyes developed MK. Four eyes exhibited recurrences; all recur- rences promptly responded to rein- stitution of continuous wear. Concluding Remarks MK remains the most serious potential adverse event associated with contact lens wear. This topic has been significantly studied over the past few decades. Results indi- cate that the rates of MK, especially those that result in vision loss, are quite low and demonstrate an ac- ceptable risk/reward ratio. The most significant risk factor for MK in contact lens wear appears to be continuous wear of lenses (re- gardless of the degree of oxygen per- meability). Other less impactful risk factors have also been identified. By controlling these risk factors, the likelihood of developing MK with contact lens wear is quite minimal. The question remains, however, regarding the relative risk of MK with the use of specialty contact lenses, especially when fit on dis- eased eyes. The data on that topic is weak, and further study may be re- quired. On the other hand, perhaps the lack of data is a result of MK rates that are too low to report. Only well-constructed long term studies will find an answer. CLS For references, please visit www. and click on document #SE2017.
