All experienced decreased vision due to keratoconus progression. Often times vision insurance covers for the scleral lens fitting. With the smaller size the RGP lens just sits on your cornea which leads to some benefits later discussed in this article. Many commonly reported minor scleral lens complications are encountered during the initial lens fitting and can be easily managed by modifying the lens parameters, lens care, or other factors such as instilling artificial tears, decreasing wearing time, or reapplying the lens.2,30,73 Compared with other reports, our subjects experienced a lower rate of midday fogging (7%), surface deposits (8.9%), and surface wetting issues (1.9%).2,30 This may be due to the lack of inclusion of first-year data in the study. Because compromised corneas are more susceptible to adverse events, it is difficult to generalize these results to keratoconus patients and determine the risks associated with scleral wear in this population. 24. 69. 45. If your condition gets worse, you may need a cornea transplant. Adverse events were divided into those that impacted physiology and those that were lens related. 4.

Due to the sheer size of a scleral lens the scleral lens touches not the cornea but the white part of your eye. The potentially most severe adverse event recorded was microbial keratitis, observed in one eye (0.6%) in our study. With scleral lens FSE correction, investigators found a greater reduction in spherical aberration (86%) compared with lenses without eccentricity correction (66%). In the long run, however, scleral lenses are generally not drastically more expensive than other specialty contact lenses. The review by Chalmers et al.38 on the annualized rates of corneal infiltrative events in daily disposable lenses (0 to 0.6% per year) compared with reusable designs (3 to 4% per year) may provide additional insights. Compliance with scheduled visits was documented. 74. These conditions include dry eyes syndrome, chemical or burn injuries to the ocular surface, keratoconus, and Sjogrens syndrome. Most interventions involved refit of the scleral lens (54.0% of interventions). A skew in sampling cannot be excluded, and calculation of incidence rates in person-years, which would facilitate comparison to soft lens studies, cannot be presented.
