topical anesthesia is numbing medicine placed directly on the eye’s surface. It is most often given as eye drops or, less commonly, a gel. It reduces pain signals from the cornea and conjunctiva for exams and minor procedures. It is widely used in optometry and ophthalmology clinics and in outpatient eye surgery settings.

A sub-Tenon block is a type of local anesthesia used around the eye. It places anesthetic medicine into the sub-Tenon space, a thin layer between the white of the eye (sclera) and a tissue covering called Tenon’s capsule. It is commonly used to numb the eye and reduce eye movement during ophthalmic procedures. Many cataract and retinal surgeries may use this technique, depending on the patient and the operation.

A peribulbar block is a type of local anesthesia used to numb the eye and reduce eye movement for certain eye procedures. It involves injecting anesthetic medication into the space around the eyeball, not into the eyeball itself. It is commonly used for cataract surgery and other operations where a still, comfortable eye is helpful. It is a form of “regional anesthesia,” meaning it targets nerves in one area rather than putting the whole body to sleep.

A retrobulbar block is an injection of local anesthetic placed behind the eyeball. It is used to numb the eye and reduce eye movement for certain eye surgeries. It is most commonly discussed in the context of cataract and other intraocular procedures. It is one option among several anesthesia approaches in ophthalmology.

A lid speculum is a small medical device used to gently hold the eyelids open. It helps clinicians see and access the front of the eye without the patient blinking. It is commonly used in ophthalmology and optometry clinics, and during eye surgery. It can be reusable or single-use, depending on the setting and manufacturer.

A speculum is a medical tool designed to gently hold tissues apart to improve visibility and access. In eye care, it usually refers to an eyelid speculum that keeps the eyelids open during an exam or procedure. It is commonly used in ophthalmology clinics, operating rooms, and procedure rooms.

povidone-iodine prep is an antiseptic “cleaning” step used to reduce germs on the skin and eye surface. It is commonly applied around the eyelids and placed on the surface of the eye before certain eye procedures. The goal is to lower the chance that microbes enter the eye during treatment. It is used in clinics, procedure rooms, and operating rooms in ophthalmology and optometry.

draping is the placement of a sterile covering around a treatment area. It helps create a clean field and separates the eye from nearby skin, hair, and clothing. It is commonly used during eye surgery and some in-office procedures. It may include adhesive edges or openings that expose only the eye being treated.

A sterile field is a carefully prepared area that is kept free of germs during a medical procedure. It uses sterile drapes, instruments, and gloves to reduce contamination. In eye care, it is commonly used for surgeries and certain in-office procedures like injections. Its goal is to lower the chance that microbes reach delicate eye tissues.

post-op follow-up means the planned check-ins after an eye procedure or surgery. It is used to confirm healing, measure vision, and look for complications early. It is commonly scheduled after cataract surgery, laser vision correction, glaucoma procedures, and retinal treatments. It can happen in a clinic visit, and sometimes parts of it may be done remotely depending on the case.

pre-op assessment means the evaluation done before an eye procedure or surgery. It combines eye measurements, medical history, and risk checks to support safe planning. It is commonly used before cataract surgery, laser vision correction, and many retinal or glaucoma procedures. It helps the care team choose the right approach and set realistic expectations.

informed consent is a structured conversation and agreement that happens before a medical test or treatment. It means you receive understandable information and have a real choice about what happens next. It is commonly used in eye exams, diagnostic imaging, medications, injections, and eye surgery. It also documents that questions were invited and that your decision was voluntary.

amniotic membrane is a thin biologic tissue that comes from the innermost layer of the placenta. In eye care, it is processed and used as a protective covering or graft on the surface of the eye. It is commonly used to support healing of the cornea (the clear front window of the eye) and conjunctiva (the thin lining over the white of the eye). Clinicians use it in both clinic-based and surgical settings, depending on the problem being treated.

A bandage contact lens is a soft contact lens used mainly to protect the surface of the eye. It acts like a “bandage” over the cornea (the clear front window of the eye). It is commonly used in ophthalmology and optometry clinics for healing, comfort, and surface protection. It is not primarily intended for routine vision correction, although it may affect vision.

punctal plugs are small medical devices placed in the tear drainage openings of the eyelids. They are commonly used to help the eye keep tears on the surface longer. They are most often discussed in the context of dry eye disease and ocular surface irritation. They are typically placed by an ophthalmologist or optometrist in an office setting.

intravitreal drugs are medications placed directly inside the eye, into the vitreous gel. They are most commonly delivered by an office-based injection performed by an ophthalmologist. The goal is to treat diseases affecting the retina (the light-sensing tissue) and nearby structures. They are widely used in modern care for retinal conditions that can threaten central vision.

azelastine is a medication used to reduce allergy-related symptoms. It belongs to the antihistamine class and is commonly used for allergic eye and nasal conditions. In eye care, it is most often prescribed as an ophthalmic solution (eye drop) for allergic conjunctivitis. It is also available in nasal spray forms for allergic rhinitis, which can overlap with eye allergy symptoms.

alcaftadine is a prescription eye drop used to reduce itchy eyes related to allergies. It is most commonly used for allergic conjunctivitis, a condition where the eye surface reacts to allergens. Clinicians use it in outpatient eye care, including optometry and ophthalmology clinics. It is typically used for symptom control rather than curing the underlying allergy.

ketotifen is a medication used to reduce allergy-related inflammation and itching. In eye care, it is most commonly used as an ophthalmic (eye drop) treatment for allergic conjunctivitis. It belongs to a class of medicines with antihistamine and mast cell–stabilizing effects. In some regions, ketotifen is also available in oral forms for allergic conditions.

olopatadine is a medication used to reduce allergy-related eye symptoms. It is most commonly used as an eye drop for allergic conjunctivitis (eye allergies). In clinical terms, it works as an antihistamine and a mast cell stabilizer. It is used in eye care settings to relieve itching and related surface irritation.
