Off the Cuff: The FTC – What They Don’t Know Will Hurt Consumers
In a few short weeks the FTC will be meeting to decide the fate of the contact lens industry and, perhaps inadvertently, the health and well-being of every contact lens wearer in the U.S. Focused on consumer rights at the expense of public safety, the FTC will be considering needless and resource-consuming new contact lens documentation requirements. It is also expected to propose generic lens substitution regulation. In this process, the FTC will have ignored the complexity of contact lens materials, the differences between contact lens designs and, most importantly, the sometimes-devastating reality that contact lenses are medical devices that, when misused or improperly fitted, can cause life-changing harm to wearers.

Determinants of the Frequency of Contact Lens Wear | ||||
Survey forms were sent to contact lens fitters in up to 40 countries between January and March for five consecutive years (2007 to 2011) to characterize and discover the determinants of the frequency of wear (FOW) of contact lenses. Practitioners were asked to record data relating to the first 10 contact lens fits or refits performed after receiving the survey form. Only data for daily wear lens fits were analyzed. Data were collected in relation to 74,510 and 9,014 soft and rigid lens fits, respectively. Overall, FOW was 5.9±1.7 days per week (DPW). Researchers reported that, when considering the proportion of lenses worn between one and seven DPW, the distribution for rigid lenses was skewed toward full-time wear (seven DPW), whereas the distribution of soft daily disposable lenses was possibly bimodal, with large and small peaks at seven and two DPW, respectively. There was significant variation in FOW among nations, ranging from 6.8±1.0 DPW in Greece to 5.1±2.5 DPW in Kuwait. For soft lenses, FOW increased with decreasing age. Females (6.0±1.6 DPW) wore lenses more frequently than males (5.8±1.7 DPW). FOW was greater among those wearing presbyopic corrections (6.1±1.4 DPW) compared with spherical (5.9±1.7 DPW) and toric (5.9±1.6 DPW) designs. FOW with hydrogel peroxide systems (6.4±1.1 DPW) was greater than that with multipurpose systems (6.2±1.3 DPW). Numerous demographic and contact lens-related factors impacted FOW. Researchers suggested that there might be a future trend toward a lower FOW associated with the increasing popularity of daily disposable lenses. |

The Risk of Blepharoptosis in Contact Lens Wearers | ||||
The aim of this systematic review was to summarize and evaluate the risk of blepharoptosis in contact lens wearers. In a PubMed search, 393 papers were found using the terms "lens and ptosis."
The abstracts were read, and 16 full text articles were reviewed. Among these, five articles were analyzed. Five studies were subgrouped, and a meta-analysis of related data suggested an increased risk of blepharoptosis in hard contact lens wearers over nonwearers (n = 7426; OR, 17.38, 95% CI = 3.71-81.29, p < 0.00001). One study was subgrouped, and the data suggested an increased risk of blepharoptosis in soft contact lens wearers over nonwearers (n = 90; OR, 8.12, 95% CI = 2.68-24.87, p < 0.0002). Authors wrote that patients wearing rigid contact lenses should be advised of the risk of ptosis, and a history of contact lens use should be sought in all patients who have acquired ptosis, as other authors also have recommended. |

Allergic Manifestations of Contact Lens Wearing | ||||
Contact lens-induced papillary conjunctivitis (CLPC) is a common ocular allergic disease in contact lens wearers, authors wrote. In its more severe form, it can cause giant papillary conjunctivitis, resulting in contact lens intolerance and the need to discontinue the use of contact lenses. This review presented the pathogenesis, clinical manifestations and management guidelines of the common disorder.
Different types of contact lenses are associated with differences in the severity of CLPC. Refitting patients with silicone hydrogel contact lenses or with daily disposable contact lenses may improve the signs and symptoms of CLPC, authors wrote. The recent introduction of the topical immunomodulatory agent tacrolimus in other severe allergic eye diseases may aid in suppressing the allergic inflammation in CLPC as well, they added. CLPC has a significant impact on the quality of vision, and should be promptly recognized by healthcare practitioners and managed by modifications of the types and wearing schedules of contact lenses, as well as novel treatment options with topical immunomodulators, authors recommended. |

ReVision Optics, Manufacturer of Raindrop Near Vision Inlay, Closing ReVision Optics, the maker of the Raindrop Near Vision Inlay, announced it is shutting down operations. A statement on the company’s website says the company “…made great strides to build a market for the surgical correction of presbyopia, but respectful of our best efforts, it is with regret, that we have to close our doors. The Raindrop Inlay will not be sold to ophthalmic practices or distributors as of Tuesday, January 30, 2018. As a result, the Raindrop Rebate will not be honored past this date…. It has been a privilege to have the opportunity to bring Raindrop Inlay to the presbyopic community and innovative ophthalmic practices.” The company instructs questions to a hotline number (1-866-934-6592), which will be staffed through April 30. Approved by the FDA in June 2016, the corneal reshaping inlay was made of a hydrogel material and inserted under a flap, similar to LASIK. About 2mm in diameter, 30µm thick and made of approximately 80% water, the inlay was the same refractive index as the cornea. When placed in the cornea, it changed the shape of the central cornea, simulating a multifocal contact lens. Read more. |
