[Thésaurus HELB]:Optique:pression intraoculaireRésumé : SIGNIFICANCE: As scleral lens wear becomes more common, understanding the impact of these lenses upon ocular physiology is critically important. Studies on the effect of scleral lens wear upon intraocular pressure (IOP) have used different instruments and have reported conflicting results. PURPOSE: The purpose of this study was to compare assessment of IOP during scleral lens wear using pneumatonometry and transpalpebral tonometry. METHODS: Twenty healthy subjects wore a small-diameter (15.2 mm) and a large-diameter (18.0 mm) scleral lens on the right eye, each for 1 hour in randomized order. IOP was assessed with pneumatonometry and transpalpebral tonometry on both eyes before lens application, immediately after lens application, after 1 hour of lens wear, and immediately after lens removal. Paired t test compared mean IOP in the study eye to the control eye. Repeated-measures ANOVA was performed to take instrumentation, lens diameter, and their interaction into account in an analysis of the change in IOP in the study eye. RESULTS: Mean peripheral IOP measured with pneumatonometry was not significantly different from baseline at any subsequent measurement. Measurements with transpalpebral tonometry, however, were significantly different during scleral lens wear immediately after application and after 1 hour of wear with both diameter lenses (P < .005), but were not significantly different after either sized lens was removed. Repeated-measures ANOVA revealed that the instrument used to measure IOP was a significant factor in IOP changes found during lens wear (P ≤ .001). CONCLUSIONS: Assessment of IOP during scleral lens wear varies based upon the instrument that is used. Although further studies are clearly needed to further elucidate this issue, clinicians should continue to monitor optic nerve structure and function in scleral lens wearers, as they do in all patients.

[Thésaurus Mesh]Lentilles de contactRésumé : SIGNIFICANCE: Scleral lenses (SLs) are increasingly being considered as the initial correction for patients with keratoconus. In this study, keratoconus patients report higher levels of comfort and visual satisfaction with SL compared with corneal gas-permeable lenses (GPs). PURPOSE: This study aimed to compare patient satisfaction and care burden associated with GP and SL for the management of keratoconus. METHODS: An electronic survey was distributed by the National Keratoconus Foundation from October 2016 to March 2017. Age at diagnosis, initial and current treatment, lens complications, access to care, lens handling time, and annual out-of-pocket treatment costs were collected. Vision, lens comfort, and ease of use satisfaction were rated from 1 to 5. RESULTS: A total of 422 responses were received, including 75 bilateral GP and 76 bilateral SL wearers. Scleral lens wearers had greater satisfaction with vision (3.2 ± 1.1 [SL] vs. 2.6 ± 1.1 [GP]; P < .001) and comfort (3.3 ± 1.0 [SL] vs. 2.2 ± 1.2 [GP]; P < .001) but similar ease of use satisfaction in both groups (2.8 ± 1.1 [SL] vs. 2.7 ± 1.1 [GP]; P < .90). Both groups reported issues with cloudy or foggy vision (GP, 63%; SL, 58%) and contact lens discomfort (GP, 77%; SL, 67%). Although GP wearers reported more issues with lens movement or loss (40 [GP] vs. 18% [SL]), they had fewer difficulties with halos (53 vs. 72% [SL]) and lens handling (40%) compared with SL wearers (63%). Gas-permeable lens (48%) and SL (45%) wearers spend 6 to 10 minutes daily handling their lenses. Sixty percent of GP wearers reported annual out-of-pocket cost expenses less than U.S.$1000, whereas only 41% of SL wearers reported the same. CONCLUSIONS: Scleral lens wearers with keratoconus report greater satisfaction with vision and comfort than do GP wearers, although both groups reported cloudy vision and lens discomfort.
