Ahmed glaucoma valve implantation
Ahmed glaucoma valve implantation is eye surgery that implants a valved drainage device to lower intraocular pressure in refractory glaucoma, mainly when trabeculectomy has failed or is unlikely to succeed.
Anterior chamber paracentesis
Anterior chamber paracentesis (ACP) is an ophthalmologic procedure using a fine needle through the cornea to withdraw aqueous humor for diagnostic testing or to lower intraocular pressure.
Canaloplasty
Canaloplasty is a glaucoma operation, first reported in 2007, that catheterizes Schlemm's canal around its full circumference, dilates it, and tensions it with a suture.
Canthotomy
Canthotomy is an emergency procedure that cuts the lateral canthus of the eye to relieve orbital compartment syndrome, usually combined with cantholysis, before irreversible vision loss occurs.
Capsulorhexis
Capsulorhexis is a cataract-surgery technique in which the surgeon tears a continuous circular opening in the lens capsule by hand, the standard method since its 1990 description.
Charles Kelman
Charles Kelman (1930–2004) was an American ophthalmologist at Manhattan Eye, Ear and Throat Hospital who invented phacoemulsification, the ultrasonic cataract-removal technique that became the standard method worldwide.
Corneal collagen cross-linking
Corneal collagen cross-linking (CXL) is an ophthalmic procedure that stiffens the cornea using riboflavin and UVA light, halting progression of keratoconus and post-LASIK ectasia; the original Dresden protocol remains the reference standard.
Couching (ophthalmology)
Couching is an ancient, now obsolete cataract operation in which a needle dislodges the clouded lens from the visual axis, leaving it inside the eye; it persists in parts of West Africa and Asia.
Dacryocystorhinostomy
Dacryocystorhinostomy (DCR) is eye surgery that creates a new path for tears to drain between the eyes and the nose when the tear duct is blocked, treating epiphora and dacryocystitis.
Descemet membrane endothelial keratoplasty
Descemet membrane endothelial keratoplasty (DMEK) is a corneal transplant operation replacing the endothelium and Descemet membrane with a thin donor graft, used mainly for Fuchs dystrophy and bullous keratopathy.
Descemet stripping endothelial keratoplasty
Descemet stripping endothelial keratoplasty (DSEK) is a partial-thickness corneal transplant for endothelial disease such as Fuchs dystrophy, replacing the endothelium and Descemet membrane through a small, sutureless incision.
Endonasal dacryocystorhinostomy
Endonasal dacryocystorhinostomy is a tear-drainage surgery performed entirely through the nose to treat watery eyes from a blocked nasolacrimal duct, avoiding the external scar of classic dacryocystorhinostomy.
Endoscopic dacryocystorhinostomy
Endoscopic dacryocystorhinostomy is surgery that uses an endoscope to create a new tear drainage pathway from the lacrimal sac to the nasal cavity, relieving epiphora and dacryocystitis.
Endotamponade
Endotamponade: intraocular gas (air, SF6, C2F6, C3F8) or silicone oil used in vitreoretinal surgery to seal retinal breaks until retinopexy; gases resorb in days to weeks, oil is permanent until removed.
Epikeratophakia
Epikeratophakia (epikeratoplasty, onlay lamellar keratoplasty): historical refractive corneal surgery introduced by Kaufman, Werblin, and Klyce at LSU around 1980, in which a prelathed donor corneal lenticule is sutured onto the de-epithelialized cornea to correct aphakia, myopia, or keratoconus; now largely abandoned.
Epiretinal membrane surgery
Epiretinal membrane surgery is a vitreoretinal procedure that peels a fibrous membrane off the macula to treat distortion and blurred vision, with about 80% of patients improving by at least two lines of visual acuity.
External dacryocystorhinostomy
External dacryocystorhinostomy (external DCR, EX-DCR) is an ophthalmic surgical procedure that treats nasolacrimal duct obstruction by creating a new tear-drainage pathway from the lacrimal sac into the nasal cavity.
Extracapsular cataract extraction
Extracapsular cataract extraction is cataract surgery that removes the lens nucleus and cortex through a 10 mm limbal incision while leaving the capsule intact, usually followed by lens implantation.
Eye Evisceration
Evisceration is an eye-removal operation that empties the eye of its internal contents while leaving the scleral shell, muscles, and orbit intact, first described in 1817.
Gel stent implantation
Gel stent implantation is a minimally invasive glaucoma procedure that lowers eye pressure by shunting fluid under the conjunctiva through the XEN Gel Stent, first FDA-cleared in 2016.
Glaucoma drainage implant surgery
Glaucoma drainage implant surgery implants a tube and plate that drain fluid from the eye's anterior chamber to a reservoir, lowering pressure; common devices include the Ahmed valve and Baerveldt implant.
Glaucoma filtration surgery
Glaucoma filtration surgery is an operation that creates a permanent drainage channel for aqueous humor, forming a filtering bleb that lowers intraocular pressure in glaucoma.
Goniotomy
Goniotomy is an eye surgery that incises the trabecular meshwork from inside the anterior chamber to improve drainage and lower intraocular pressure, used mainly for primary congenital glaucoma and other open-angle glaucomas.
Implantable collamer lens implantation
Implantable collamer lens (ICL) implantation is a refractive surgery procedure that corrects myopia by placing a phakic intraocular lens between the iris and the natural lens.
Internal limiting membrane flap technique
The internal limiting membrane flap technique is a vitreoretinal surgical maneuver in which an ILM remnant is inverted over a macular hole to promote its closure.
Intracameral injection
An intracameral injection, or anterior chamber injection, places medication into the fluid-filled space between the cornea and iris, most often antibiotics at the end of cataract surgery.
Intraocular administration
Intraocular administration is a drug delivery route in which medication is injected directly into compartments of the eye, most commonly the vitreous cavity, to treat retinal disease.
Intraocular injection
Intraocular injection is a clinical procedure that delivers a drug directly into the eye to treat retinal diseases, minimizing systemic absorption; intravitreal injection is the most common form.
Intraocular lens implantation
Intraocular lens implantation is the surgical placement of an artificial lens inside the eye, replacing the natural lens removed during cataract surgery or correcting refractive error.
Intrascleral intraocular lens fixation
Intrascleral intraocular lens fixation is a sutureless surgical technique that secures a posterior chamber lens implant in eyes lacking capsular support by burying its haptics in scleral tunnels.
