The present invention relates to collagenous membranes produced from amnion, herein referred to as a collagen biofabric. The collagen biofabric of the invention has the structural integrity of the native non-treated amniotic membrane, i.e., the native tertiary and quaternary structure. The present invention provides a method for preparing a collagen biofabric from a placental membrane, preferably a human placental membrane having a chorionic and amniotic membrane, by decellularizing the amniotic membrane. In a preferred embodiment, the amniotic membrane is completely decellularized. The collagen biofabric of the invention has numerous utilities in the medical and surgical field including for example, blood vessel repair, construction and replacement of a blood vessel, tendon and ligament replacement, wound-dressing, surgical grafts, ophthalmic uses, sutures, and others. The benefits of the biofabric are, in part, due to its physical properties such as biomechanical strength, flexibility, suturability, and low immunogenicity, particularly when derived from human placenta.

An intraocular lens comprises optical part configured to be implanted in an eye of a subject. The intraocular lens further comprises at least one aspheric surface configured, in combination with a lens in the capsular bag of an eye, to reduce an aberration of a wavefront passing the eye. The aberrations may include astigmatism, coma, and/or spherical aberrations. An aberration of the intraocular lens may be expressed as a linear combination of Zernike polynomial terms that may include a Zernike coefficient a₁₁. The Zernike coefficient a₁₁ may be selected to reduce a spherical aberration of a wavefront passing the eye and/or to compensate for an average value resulting from a predetermined number of estimations of the Zernike coefficient a₁₁ in a population of corneas and capsular bag lenses.

The present invention refers to pharmaceutical formulations based on lipids for ophthalmic use comprising a phospholipid component composed of zwitterionic phospholipids of natural origin and an oily component composed of oils of natural origin emulsified in water. In particular, the invention refers to ophthalmic formulations useful, for example, for transporting drugs to the eye and in the treatment of ocular dryness, capable of restoring the lipid layer of the tear film. In particular, in a non-transitory but pathological situation such as the dry eye syndrome, such formulations also succeed in reducing the often-present inflammatory component.

The subject invention provides a mechanism by which steroidal quinol compounds confer beneficial ophthalmic effects. The subject compounds possess a lipophilic-hydrophilic balance for transcorneal penetration and are readily reduced into parent phenolic A-ring steroid compounds to provide protection or treatment against various ocular symptoms and disorders. The compounds according to the subject invention appear to be highly advantageous as prodrugs to provide protection and/or treatment against ocular disorders. These prodrugs confer lipid solubility optimal for transocorneal penetration and are readily converted to endogenous reducing agents into active phenolic A-ring steroid compounds. To the extent that these prodrugs have reduced feminizing effects and systemic toxicity, they would be expected to be quite advantageous for protecting or treating the eye against ocular disorders such as cataract or glaucoma without undesired (systemic) side effects).
