| Accomodation | Process by which the lens continually changes shape to maintain focus of an image on the retina |
| Bridle Suture | A temporary traction suture placed through the scleraand used to pull the globe laterally for exposure of the posterolateralsurface. It is called this because of resemblance to a horse's bridle. |
| Cataract | Closing of the eye, caused by a disease in which the crystalline lens of the eye, its capsule, or both, become opaque. This prevents light from focusing on the retina, resulting in visual distortion. This may develop as a result of disease or injury |
| Conformer | A device placed in the socket after enucleation or evisceration to fill the orbital space. |
| Cryotherapy | A cold probe is used to freeze tissue such as sclera, ciliary body (for galucoma), or retinal layers after detachment. |
| Diathermy | Low-power-cautery used to make the sclera over an area of retinal detachement |
| Enucleation | Surgical removal of the globe and accessory attachments |
| Evisceration | Surgical removal of the contents of the eyeball, with the sclera left intact |
| Exenteration | Removal of the entire contents of the orbit |
| Focal point | A point where light rays converge after passing through a len. |
| Glaucoma | A group of diseases characterized by elevation of the intraocualr pressure. Sustained pressure on the optic nerve and other structures may result in ischemia and blindness |
| Keratoplasty | Surgery of the cornea. The term penetratiing _______ refers to corneal transplantation |
| Muscle recession | Surgery in which the eye muscle is moved back to release the globe |
| Muscle resection | Surgical shortening of the eye muscle to pull the globe into correct position |
| Phacomulsification | A proces by which high-frequency sound waves are used to emulsify tissue, such as a cataract |
| Ptergium | A triangular membrane that arises from the medial cathus; the tissue may extend over the cornea, causing blindness |
| Refraction | A phenomenum of physics in which light rays are bent as they pass through a transparent medium that is denser than air. In the eye, this occurs as light enters the front of the eye and passes through the cornea lens, aqueous humor, and vitreous |
| Spatula needle | A flat-tip suture needle commonly ised in opthalmic surgery |
| Strabismus | Inability to coordinate the the extraocular muscles, which prevents binocular vision |
| Trabeculectomy | Surgical removal of a portion of the trabecula to improve the outflow of the aqueous humor for glaucoma |
