|
|
Term
| Laser procedure for refractive correction that does not involve corneal flap construction; can be performed on a thin cornea; long-term stability; requires a longer healing period before vision returns; slightly higher risk of infection |
|
Definition
| Photorefractive keratectomy (PRK) |
|
|
Term
| Laser procedure for refractive correction that involves loosening the epithelium with alcohol, carefully rolling it back, treating the underlying surface with the laser, then replacing the sheet of epithelium back over the cornea |
|
Definition
| LASEK (laser subepithelial keratomileusis) |
|
|
Term
| Laser procedure for refractive errors in which a flap is reflected back and the laser energy is delivered to reshape the cornea; fast visual recovery; thin corneas not good candidates; diffuse lamellar keratitis (deposits underneath the flap) |
|
Definition
| LASIK (laser in situ keratomileusis) |
|
|
Term
| Corrective procedure for refractive errors (low hyperopia & astigmatism) that uses a fine conducting needle to deliver radiofrequency energy into the peripheral cornea in set patterns. This shrinks corneal collagen fibers, thereby reshaping the cornea. |
|
Definition
|
|
Term
| Corrective procedure for pts with refractive errors who are not candidates for corneal surgery (cornea too thin, too flat, too steep) |

Definition
| iris, ciliary body, choroid |
|
|
Term
| Form of cellulitis that involves anterior lid structures and periorbital tissues. The eye is normal. Examination will reveal lid swelling and erythema, but visual acuity, motility, and ocular structures will be normal. |

Term
| Term used to describe hardening of the lens as a result of age; contributes to presbyopia |

|
|
Term
| Give MOA and drug class for this group of drugs: epinephrine, dipivefrin (propine), apraclonidine, brimonidine |
|
Definition
| Adrenergic agonists that treat glaucoma by lowering resistance to aqueous outflow |
|
|
Term
| Give MOA and drug class for this group of drugs: pilocarpine, carbachol, and echothiphate iodide |
|
Definition
| Cholinergic agonists (parasympathomimetics) work by increasing aqueous outflow |
|
|
Term
| Treatment of this eye disorder is with cyclosporine drops; important to treat bc of increased risk of corneal ulceration |
|
Definition
