Ophthalmic Surgery Glossary

A minimally invasive glaucoma surgery that opens the trabecular meshwork using a microcatheter or probe.

The supporting arms or loops of an intraocular lens that position and stabilize the lens within the eye. Essential compo...

Abnormally low intraocular pressure, typically below 5-8 mmHg, that can compromise eye function.

Direct injection of medication into the vitreous cavity of the eye through the pars plana.

Intraocular lens; an artificial lens implanted in the eye to replace the natural crystalline lens.

Surgical creation of a small opening in the iris to improve aqueous humor drainage.

Surgical reshaping of the cornea by removing and remodeling stromal tissue to correct refractive errors.

Corneal transplantation surgery involving replacement of diseased corneal tissue with healthy donor tissue.

Inability to close the eyelids completely, exposing part of the cornea and conjunctiva.

Laser-assisted in situ keratomileusis; a refractive surgery using laser energy to reshape the cornea.

Condition where corneal stem cells located at the limbus are depleted, causing conjunctival overgrowth.

Full-thickness defect in the central retina causing severe vision loss in the affected eye.

Congenital condition characterized by abnormally small eye development, requiring specialized surgical approaches.

Minimally invasive glaucoma surgery techniques designed to reduce intraocular pressure safely.

An intraocular lens designed with multiple focal points to provide vision at various distances without glasses.

Pupil dilation, often induced pharmacologically for surgical procedures or examination.

Rare bilateral condition of extremely small but structurally normal eyes, predisposing to angle-closure glaucoma.

A neodymium-doped yttrium aluminum garnet laser used for posterior capsulotomy and peripheral iridotomy procedures.

Laser treatment applied to the peripheral retina to reduce abnormal blood vessel growth in diabetic retinopathy.

The flat anterior portion of the ciliary body where surgical entry is made for vitreoretinal procedures.

The study and application of ultrasonic energy settings during cataract surgery.

A surgical technique using ultrasound energy to break up and remove cataracts through a small corneal incision.

Secondary angle-closure glaucoma caused by lens swelling that mechanically blocks aqueous humor drainage.
