💧 Artificial Tears

Artificial tears are lubricating eye drops used to relieve dryness, burning, irritation, fluctuating vision, and discomfort caused by dry eye disease. They are the first-line treatment for many ocular surface conditions and are available over the counter.

Generic Name Brand Typical Frequency Common Uses
Carboxymethylcellulose Refresh Tears® PRN to QID+ Mild-to-moderate dry eye
Carboxymethylcellulose Refresh Plus PF® PRN Frequent lubrication
Polyethylene Glycol / Propylene Glycol Systane Ultra® PRN Dry eye & eye strain

Gel Lubricant Refresh Celluvisc® QHS or PRN Moderate-to-severe dry eye
Lubricating Ointment Refresh PM® QHS Nighttime lubrication
Mineral Oil / White Petrolatum Systane Nighttime® QHS Severe dry eye while sleeping
Clinical Pearl: If artificial tears are needed more than 4–6 times per day, preservative-free formulations are generally preferred because they reduce preservative exposure to the ocular surface.

🌼 Allergy Eye Drops

Allergy eye drops relieve itching, redness, tearing, and swelling caused by seasonal or perennial allergic conjunctivitis. Most modern allergy medications combine an antihistamine with a mast cell stabilizer.

Generic Name Brand Typical Frequency Common Uses
Olopatadine 0.2% Pataday Once Daily® QD Seasonal allergies
Olopatadine 0.7% Pataday Extra Strength® QD Moderate-to-severe allergies
Alcaftadine Lastacaft® QD Allergic conjunctivitis
Ketotifen Zaditor® BID Eye itching
Ketotifen Alaway® BID Seasonal allergies
Bepotastine Bepreve® BID Prescription allergy treatment
Epinastine Elestat® BID Allergic conjunctivitis
Azelastine Optivar® BID Seasonal allergic conjunctivitis
Clinical Pearl: Starting allergy eye drops before allergy season often provides better symptom control than waiting until symptoms become severe. Artificial tears may also help rinse pollen and other allergens from the surface of the eye.
Important: Typical dosing frequencies shown above are based on common prescribing recommendations. Your eye care professional may recommend a different dosing schedule depending on your individual condition. Always follow your prescription instructions.

👁️ Glaucoma Eye Drops

Glaucoma medications lower intraocular pressure (IOP) by either reducing aqueous humor production or improving its drainage. They are essential for slowing the progression of glaucoma and preventing permanent vision loss.

Generic Name Brand Typical Frequency Common Uses

TravoprostTravatan Z®QHSOpen-angle glaucoma

Brimonidine/TimololCombigan®BIDCombination glaucoma therapy
Brinzolamide/BrimonidineSimbrinza®TIDCombination glaucoma therapy
Netarsudil/LatanoprostRocklatan®QHSCombination glaucoma therapy
Clinical Pearl: Glaucoma medications work best when used consistently every day. Even if your vision seems stable, stopping glaucoma medications without medical supervision may lead to irreversible optic nerve damage.

🦠 Antibiotic Eye Drops

Antibiotic eye drops are used to treat bacterial eye infections. They are not effective against viral conjunctivitis or allergic eye disease.

Generic Name Brand Typical Frequency Common Uses
MoxifloxacinVigamox®TIDBacterial conjunctivitis
BesifloxacinBesivance®TIDBacterial conjunctivitis
GatifloxacinZymaxid®TIDConjunctivitis

Trimethoprim / Polymyxin BPolytrim®QIDConjunctivitis
Erythromycin OintmentGenericQHS–QIDBlepharitis, conjunctivitis
Bacitracin OintmentGenericQHS–QIDEyelid infections
Clinical Pearl: Always complete the full course of antibiotic treatment, even if symptoms improve after a few days. Stopping antibiotics early may allow bacteria to survive and increase the risk of recurrence.

🔥 Steroid & NSAID Eye Drops

Anti-inflammatory eye drops reduce pain, redness, and inflammation following eye surgery or during inflammatory eye diseases. These medications should only be used under the supervision of an eye care professional.

Generic Name Brand Typical Frequency Common Uses
Prednisolone AcetatePred Forte®QID (then tapered)Uveitis, inflammation
DifluprednateDurezol®QID (then tapered)Post-operative inflammation

BromfenacProlensa® / BromSite®QD–BIDPost-cataract surgery
NepafenacNevanac® / Ilevro®QD–TIDPost-operative inflammation
DiclofenacVoltaren Ophthalmic®QIDInflammation & pain
Clinical Pearl: Steroid eye drops can increase intraocular pressure and may contribute to cataract formation with prolonged use. They should never be used without appropriate monitoring by an eye care professional.

*Important: Some medications—particularly antibiotics used for severe corneal infections—may require much more frequent dosing (such as every hour) at the beginning of treatment. Always follow the instructions provided by your prescribing eye care professional rather than the general dosing guide shown here.

👁️ How to Instill Eye Drops Correctly

Using eye drops correctly helps maximize the effectiveness of your medication while reducing contamination and medication waste.

❓ Frequently Asked Questions

Can I use artificial tears every day?
Artificial tears are generally safe for daily use. If you require lubricating drops more than four to six times per day, preservative-free formulations are often recommended.
How long should I wait between eye drops?
Wait at least 5 minutes between different eye drops. This allows the first medication to be absorbed before another drop is applied.
Can I wear contact lenses while using eye drops?
Some eye drops are compatible with contact lenses, while others require lenses to be removed before use. Always follow the instructions provided with your medication.
Can I use someone else’s prescription eye drops?
No. Prescription eye drops are prescribed for specific conditions and individual patients. Sharing medications may delay proper treatment and increase the risk of complications.
Can eye drops expire?
Yes. Expired eye drops may become contaminated or lose effectiveness. Replace medications after their expiration date and discard multi-dose bottles according to the manufacturer’s recommendations.
Why do some eye drops burn or sting?
A brief burning sensation is common with certain medications. However, severe pain, worsening redness, significant swelling, or decreased vision should be evaluated promptly by an eye care professional.
