Abstract Details


The purpose of this study is to determine if recovery of corneal edema can be increased by using the Hyper CL™. Corneal edema from inadequate endothelial pump function is one of the most common complications of cataract surgery. Various causes for this endothelial dysfunction can be divided into four categories including (a). mechanical injury, (b). inflammation/infection, (c). chemical injury, and (d). concurrent eye disease.


Barzilai Medical Center, Ashkelon, Israel


On a preliminary series of 7 eyes, the following results were obtained after 24 hours of wear of the Hyper-CL™ Soft contact lens after cataract surgery. Patients with pachymetry readings above 590µm were selected for the treatment with the contact lens.The patient was fitted with the lens directly after surgery and pachymetry was performed. The patient returned 24 hours later and the lens was removed and pachymetry was performed again.


Post-surgical pain diminished and visual acuity improved dramatically. Mean reduction of corneal edema was 55 microns. There are indications that the Hyper CL™ soft contact lens act as reservoir for Ophthalmic medical drops without the drops interfering with lens parameters. In addition there was no control group in this experiment.. No special treatment for edema was considered for corneal thicknesses below 590µm. Studies have showed that corneal thickness stabilized in 74% of patients within a week and in 26% of patients during the second week. Older patients and more primary corneal edema needed longer time to recover (P < .0001).


The Hyper Cl™ is a good compliment for treating post-surgical corneal edema, with less usage of eye drops and fast recovery. The lens might feel uncomfortable initially. The visual acuity recovery will also be faster. The Hyper Cl™ is a safe method for treatment of corneal edema post cataract surgery as well as after refractive lens exchange.
