Scleral lenses and IOP THE SCLERAL LENS VAULT SCLERAL LENSES AND INTRAOCULAR PRESSURE Scleral contact lenses have found an irreplaceable niche for managing corneal irregularity and #ocular surface disease. Like any other type of contact lens, wearing them is not without risk of complications. Recently, there has been renewed concern about whether #sclerallenses cause increases in #intraocular pressure (IOP) during wear and shortly after removal (McMonnies, 2016). Research and Data The first modern study to evaluate IOP during scleral lens wear measured IOP of 29 healthy subjects before, during, and after lens wear (Nau et al, 2016). A pneumatonometer was used to measure IOP with a scleral lens in situ. Results indicated that #sclerallens wear did not increase IOP during and after wear; however, there were outliers that did show #increasedIOP. In addition, a poster presented at the 2018 Global #SpecialtyLens Symposium meeting by Turpin et al showed data from a study also measuring IOP of 14 individuals during #sclerallenswear. For this study, IOP was measured using a hand-held tonometer, which allows for IOP measurement over the eyelid (Diaton tonometer, BiCOM Inc) with a scleral lens in place. This study reported an average of 7 mmHg increase during the course of scleral lens wear. And, a recent study by Michaud et al (2018) reported similar findings; it showed an average increase of 5 mmHg regardless of the scleral lens diameter worn.
