Introduction This patient is a 51 YO female who had bilateral Penetrating Keratoplasties around 30 years ago in Rotterdam. Her grafts have become ectatic over the years and now exhibit signs of Rim Ectasia. This presents itself as a thinning of the host cornea leading to a tilting of the graft and a significant...
Read moreBackground Type 1 lattice corneal dystrophy (LCD1) is a rare hereditary bilateral disorder of the cornea. This is a result of an autosomal dominant mutation of the TGFBI (transforming growth factor beta induced) gene which leads to accumulation of amyloid deposits in stroma1 Variable clinical appearance depends on the...
Read morePenetrating keratoplasty in patients with keratoconus may provide good long‐term visual rehabilitation. There is a relatively low rate of graft failure in this cohort of patients. Graft rejection has been reported to be 5.8–41% with most rejections occurring in the first 2 years. [1-5]. Irregular and high astigmatism may be common...
Read moreThe Optimum range of materials has become established as one of the most popular RGP materials on the market. Recent years have seen remarkable growth in the usage of both ortho-k and scleral lens usage and, in response to this Contamac have developed Optimum Infinite, a hyper-Dk material which cuts...

Read moreI have no idea what LASIK (laser eye surgery) surgeons are thinking when they perform surgery on engineers with large pupils, let alone engineers with 10-mm pupils when dark adapted (Figure 1). Figure 1. 10-mm dark adapted pupil. Such an engineer sought out our office for a scleral fitting...
Read moreIntroduction Acanthamoeba is a free-living unicellular protozoon commonly found in fresh water and soil. The protozoa can be found in two forms: a metabolically active trophozoite and a resistant cyst. Acanthamoeba keratitis (AK) is an infection primarily associated with soft contact lens wearers who demonstrate improper contact lens hygiene...
Read moreIntroduction Limbal stem cell deficiency (LSCD) results in dysfunction and/or loss of the stem cells in the basal limbal area. These cells are responsible for maintaining and replenishing the corneal epithelium. This change in corneal tissue composition results in conjunctival epithelial ingrowth, persistent epithelial defects, chronic inflammation, and neovascularization.1,5 There...
