Contact Lens & Anterior Eye features a paper by Kambar et al looking at the correlation of back optic zone radius measurement of (R)GP lenses using a keratometer and a radiuscope. The back optic zone radii of 100 spherical PMMA trial contact lenses were measured using a standard radiuscope and a standard keratometer, with a lens holding device positioned on the headrest. The uncorrected back optic zone radius measurements between the two instruments were similar (the mean difference being 0.003mm). With the unavailability of radiuscopes in contact lens practices around the world, a keratometer may be used as a valuable replacement, the study concludes.

The January 20^th issue of Contact Lenses Today presented a photo showing a 13-year-old patient who was poked in the eye with a finger and fingernail during a basketball event. Interestingly, the scleral lens that she was wearing protected her cornea. The force of the trauma broke the lens, and while one half immediately came out of the eye, the other half rested nicely in place, superiorly. The resulting conjunctival hemorrhage apparently occurred as a result of the fingernail scratching the conjunctival surface after sliding off of the scleral lens - but the cornea was unaffected. The January 6th issue of Contact Lenses Today presented a photo showing severe corneal edema beneath a scleral lens on a cornea with a corneal graft. Although clinical signs of edema seem rare in scleral lens wearers, in corneal graft patients this is more likely to occur because of the suboptimal condition of the corneal endothelium. Jason Jedlicka presents a case report on a neurotropic keratitis in Review of Cornea & Contact Lenses. Desperate situations sometimes call for desperate measures, he indicates. Scleral lenses-with their capability of holding a moisture chamber to the corneal surface, ability to vault over the cornea and avoid contact with the corneal surface, and large overall diameter for comfort and stability-may be a an option for treating these conditions.
