Automated lamellar keratoplasty: Automated Lamellar Keratoplasty, commonly abbreviated to ALK uses a device called a microkeratome to separate a thin layer of the cornea and create a flap. The flap is then folded back, and the microkeratome removes a thin disc of corneal stroma below.Corneal transplantationBullous keratopathyKeratoconusCorneal endothelium: The corneal endothelium is a single layer of cells on the inner surface of the cornea. It faces the chamber formed between the cornea and the iris.X-linked endothelial corneal dystrophy: X-linked endothelial corneal dystrophy (XECD) is a rare form of corneal dystrophy described first in 2006, based on a 4-generation family of 60 members with 9 affected males and 35 trait carriers, which led to mapping the XECD locus to Xq25. It manifests as severe corneal opacification or clouding, sometimes congenital, in the form of a ground glass, milky corneal tissue, and moon crater-like changes of corneal endothelium.L. V. Prasad Eye InstituteKramers' opacity law: Kramers' opacity law describes the opacity of a medium in terms of the ambient density and temperature, assuming that the opacity is dominated by bound-free absorption (the absorption of light during ionization of a bound electron) or free-free absorption (the absorption of light when scattering a free ion, also called bremsstrahlung).Phillips (1999), p.Astigmatism: An optical system with astigmatism is one where rays that propagate in two perpendicular planes have different focus. If an optical system with astigmatism is used to form an image of a cross, the vertical and horizontal lines will be in sharp focus at two different distances.Retrograde amnesiaRobert Atkyns (topographer): Sir Robert Atkyns (1647–1711) was a topographer, antiquary, and Member of Parliament. He is best known for his county history, the Ancient and Present State of Gloucestershire.Chronic superficial keratitisLattice corneal dystrophyPhotoablation: Photoablation is the use of light or lasers to destroy tissues. The excimer laser of deep ultra-violet light is mainly used in Photoablation.Circular knittingCorneal ulcerCorneal perforation: Corneal perforation is an anomaly in the cornea resulting from damage to the corneal surface. A corneal perforation means that the cornea has been penetrated, thus leaving the cornea damaged.Fairness to Contact Lens Consumers Act: The Fairness to Contact Lens Consumers Act (, 117 Stat. 2025, 2026, 2027, 2028 and 2029, codified at et seq.Corneal neovascularizationRefractive surgery: Refractive eye surgery is any eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses. This can include various methods of surgical remodeling of the cornea or cataract surgery.Mini asymmetric radial keratotomyBarbed suture: A barbed suture is a type of knotless surgical suture that has barbs on its surface. While suturing tissue, these barbs penetrate inside the tissue and lock them into place, eliminating the need for knots to tie the suture.Intraocular lens power calculation: The aim of an accurate intraocular lens power calculation is to provide an intraocular lens (IOL) that fits the specific needs and desires of the individual patient. The development of better instrumentation for measuring the eye's axial length (AL) and the use of more precise mathematical formulas to perform the appropriate calculations have significantly improved the accuracy with which the surgeon determines the IOL power.Chemical eye injury: Chemical eye injury or chemical burns to the eye are due to either an acidic or alkali substance getting in the eye. Alkalis are typically worse than acidic burns.Xenotransplantation: Xenotransplantation (xenos- from the Greek meaning "foreign"), is the transplantation of living cells, tissues or organs from one species to another.Xenotransplantation.Aberrations of the eye: The eye, like any other optical system, suffers from a number of specific optical aberrations. The optical quality of the eye is limited by optical aberrations, diffraction and scatter.Photorefractive keratectomyCryoLifeCorrosive substanceIntraoperative floppy iris syndromeCorneal keratocyte: Corneal keratocytes (corneal fibroblasts) are specialized fibroblasts residing in the stroma. This corneal layer, representing about 85-90% of corneal thickness, is built up from highly regular collagenous lamellae and extracellular matrix components.Artificial organAtomic force acoustic microscopy: Atomic Force Acoustic Microscopy (AFAM) is a type of scanning probe microscopy (SPM). It is a combination of acoustics and atomic force microscopy.GlaucomaNeuromorphology: Neuromorphology (from Greek νεῦρον, neuron, "nerve"; μορφή, morphé, “form”; -λογία, -logia, “study of”[is the study of nervous system] form, shape, and structure. The study involves looking at a particular part of the nervous system from a [[Molecular biology|molecular and cellular level and connecting it to a physiological and anatomical point of view.Wound dehiscence: Wound dehiscence is a surgical complication in which a wound ruptures along a surgical suture. Risk factors are age, diabetes, obesity, poor knotting or grabbing of stitches, and trauma to the wound after surgery.Charles D. Phelps: Charles Dexter Phelps (September 16, 1937 – September 13, 1985) was a prominent American medical doctor, professor, and researcher in the field of ophthalmology. The clinical studies he oversaw contributed to significant advances in the scientific understanding and surgical and pharmacological treatment of glaucoma.Intraocular pressureEye injuryCataract surgeryCorneal limbus: The corneal limbus is the border of the cornea and the sclera (the white of the eye). The limbus is a common site for the occurrence of corneal epithelial neoplasm.Saal Greenstein syndrome: Saal Greenstein syndrome is a very rare autosomal recessive genetic disorder characterized by stunted growth, short limbs, microcephaly, and an anomalous cleavage of the anterior chamber of the eye. The disorder is similar to Robinow syndrome except for anterior chamber anomalies and, in one case, hydrocephalus.Esthesiometer: An esthesiometer (British spelling aesthesiometer) is a device for measuring the tactile sensitivity of the skin (or mouth, or eye, etc.).EndophthalmitisPolyamide: A polyamide is a macromolecule with repeating units linked by amide bonds.Palmer, R.LenticonusRimless eyeglasses: Rimless eyeglasses, are a type of eyeglasses in which the lenses are mounted directly to the bridge and/or temples. The style is divided into two subtypes: three piece glasses are composed of lenses mounted to a bridge and two separate temple arms, while rimways (also called cortlands) feature a supporting arch that connects the temples to the bridge and provides extra stability for the lenses.Avi Wallerstein: Avi Wallerstein is a Canadian laser eye surgeon who practices in Montreal and Toronto. In 2001, he and Mark Cohen founded LASIK MD, Canada's largest provider of laser refractive surgery.ShinglesAlternariosis: Alternariosis is an infection by alternaria, presenting cutaneously as focal, ulcerated papules and plaques.Ophthalmic Viscosurgical Device: Ophthalmic Viscosurgical Device (OVD) is viscoelastic solution used in eye surgery also referred to as viscoelastic agents. Their introduction has had a profound influence on the evolution of extracapsular and phacoemulsification surgery, and their use has decreased the incidence of corneal edema as aPhakic intraocular lens: Phakic intraocular lens (PIOL) is a special kind of intraocular lens that is implanted surgically into the eye to correct myopia (nearsightedness). They are called "phakic" because the eye's natural lens is left untouched.Optimax: Optimax is a UK-based laser eye treatment specialist which has 38 locations nationwide. Optimax was established as one of the first private clinics to offer laser eye surgery.Imbert-Fick law: The Imbert-Fick "law" was invented by Hans Goldmann (1899–1991) to give his newly marketed tonometer (with the help of the Haag-Streit Company) a quasi-scientific basis; it is mentioned in the ophthalmic and optometric literature, but not in any books of physics. According to Goldmann,Goldmann H.Trabeculoplasty: Trabeculoplasty is a laser treatment for glaucoma. It is done on an argon laser equipped slit lamp, using a Goldmann gonioscope lens mirror.Artificial tearsIris dilator muscleCoherence theory: In physics, coherence theory is the study of optical effects arising from partially coherent light and radio sources. Partially coherent sources are sources where the coherence time or coherence length are limited by bandwidth, by thermal noise, or by other effect.
