Abstract: An ophthalmic composition comprises active vitamin D as an effective component and is used for preventing deterioration of the optical transparency, occurrence of high intraocular pressure diseases or defective sight, observed after an ophthalmic operation, due to hyperplasia of the anterior ocular cells in the tissues damaged by the ophthalmic operation, which are in course of a healing process, and/or excess production of cellular materials. The ophthalmic composition can be dropped in the eye after operations such as those for cataract, for transplantation of intraocular lenses and for cornea to maintain the intraocular transparency of the anterior ocular region, to control the hyperplasia of the anterior ocular cells in the tissues damaged by the ophthalmic operation, which are in course of a healing process, and/or excess production of cellular materials and to thus prevent any reduction of visual acuity.

Abstract: A sponge which is placed on the cornea for laser treatment to absorb unavoidable exuded fluids from the peribulber. This corneal sponge offers protectiveness, convenience and improved effectiveness of corneal laser therapy. The corneal sponge has a surgical space to expose the portion of the cornea to be treated, and is marked for accurate and easy alignment of the microscopic field. The corneal sponge contains a cool ophthalmic solution used to minimize inflammatory response which may cause postoperative complications such as corneal haze and inconsistent corneal refractions.
