Are Eye Injections Painful? Common Patient Concerns Answered
Why Eye Injections Are Recommended
Eye injections deliver medication directly into the vitreous inside your eye to treat serious retinal conditions. We most often recommend this treatment for wet age-related macular degeneration, diabetic macular edema, and retinal vein occlusion. These conditions can cause fluid leakage, abnormal blood vessel growth, or swelling in the central part of your retina.
Other conditions that may require intravitreal injections include myopic choroidal neovascularization and certain cases of inflammatory or uveitic macular edema. Left untreated, these diseases can lead to permanent vision loss. Direct injection allows the medication to reach the affected tissue in concentrations that eye drops or pills cannot achieve.
The medications we inject work by stopping abnormal blood vessel growth and reducing fluid buildup in your retina. Anti-VEGF medications are the most common type we use, and they help preserve your current vision or even improve it in many cases. In some situations, we may recommend steroid injections or implants instead of or in addition to anti-VEGF therapy, particularly for certain types of swelling or inflammation.
Steroid options can include injections of triamcinolone or longer-acting steroid implants. These may be chosen based on the specific cause of your retinal condition. It is important to know that steroids carry a higher risk of raising eye pressure or accelerating cataract formation, so we monitor closely if we use them.
- They slow or halt disease progression
- They reduce swelling and fluid leakage in the retina
- They help maintain your ability to read, drive, and see faces
- Intravitreal delivery provides targeted treatment with fewer systemic effects
Treatment schedules vary based on your specific condition and how your eyes respond to the medication. Initially, we may recommend injections every four to eight weeks to stabilize your condition. Some patients need ongoing monthly treatments, while others can extend the interval between injections over time. Different anti-VEGF medications have varying durations of action, which can affect your injection schedule.
During your follow-up visits, we will monitor your retina with imaging tests to determine the best schedule for you. The goal is to maintain your vision with the fewest number of injections possible while keeping your condition under control.
What the Eye Injection Experience Feels Like
When you arrive for your appointment, we will start by putting numbing drops in your eye. These drops take a few minutes to work and eliminate most of the sensation on the surface of your eye. We will also clean the area around your eye and the surface of your eye itself with a special antiseptic solution, typically povidone-iodine, to prevent infection. We use a no-touch sterile technique throughout the procedure.
If you have a history of iodine or betadine allergy, please let us know so we can use an alternative antiseptic prep. You will be positioned comfortably, usually reclined in a chair. We use a small device to gently hold your eyelids open so you do not need to worry about blinking during the injection. You may be asked to look in a certain direction and to minimize talking during the injection to help maintain sterility.
Most patients report feeling very little pain when the needle enters the eye. Because of the numbing drops, the injection itself usually feels more like pressure than a sharp sensation. The needle is very fine and is placed through the sclera, the white of the eye, in the pars plana area.
- The anesthetic drops numb the eye surface effectively
- The needle passes through tissue with few pain receptors
- The entire injection takes only a few seconds
- Many patients are surprised by how little they feel
While you should not feel sharp pain, you may notice other sensations during the procedure. Some patients describe a feeling of pressure or fullness as the medication enters the eye. Others report a mild scratching or irritation feeling, similar to having an eyelash in your eye.
These sensations are normal and temporary. They result from the eye being held open, the antiseptic solution on the surface, or the brief increase in eye pressure from the medication volume. You may also notice an antiseptic taste or increased tearing during or right after the procedure. In some practices, we may check your eye pressure shortly after the injection as a precaution.
Right after the injection, your vision in the treated eye will likely be blurry or cloudy. You may see dark spots, floaters, or what looks like a small bubble moving in your field of vision. This happens because the medication sits inside the vitreous and takes time to disperse.
The blurriness typically clears within a few hours, though it may take up to a day in some cases. A small bubble or a few new floaters can be normal and will usually dissolve or settle out of your line of sight within a day or two. However, a sudden increase in floaters, worsening blur, flashes of light, or a curtain or shadow across your vision should prompt you to call our office right away.
How We Minimize Discomfort During Eye Injections
We apply topical anesthetic drops to the surface of your eye several minutes before the injection. These drops contain medications like proparacaine or tetracaine that numb the cornea and conjunctiva. We may apply the drops more than once to ensure complete numbness.
- The drops work within one to two minutes
- They eliminate sensation on the eye surface
- The numbing effect lasts through the procedure
- Additional drops can be applied if needed
Beyond anesthetic drops, we take several steps to make your experience as comfortable as possible. We work in a calm, quiet environment and explain each step before we do it. Our team moves efficiently to keep the procedure time short, and we use the finest needles available to minimize tissue disruption.
Some practices offer additional options such as anesthetic gel or a small injection of local anesthetic under the conjunctiva. We can discuss these choices with you if you have had previous discomfort or feel especially anxious.
Your state of mind can affect how you experience the injection. Taking slow, deep breaths before and during the procedure helps reduce anxiety and keeps you from tensing up. Focus on breathing rather than trying to watch what we are doing.
- Arrive a few minutes early to settle in
- Let us know if you feel anxious or have concerns
- Keep your head still and look in the direction we indicate
- Remember that the actual injection takes only seconds
- Trust that our team has performed this procedure many times
Caring for Your Eye After an Injection
In the day or two after your injection, you may notice some mild irritation or a gritty feeling in your treated eye. Your eye might feel slightly scratchy, as if you have something in it, or it may water more than usual. A small amount of redness on the white of your eye is also common and results from the needle passing through the conjunctiva. A subconjunctival hemorrhage, which is a small bloodshot patch, can look dramatic but is usually benign and will fade over one to two weeks.
These sensations are a normal part of healing and should improve steadily. Most patients find that any discomfort is gone within one to two days.
Most patients do not need antibiotic drops after an intravitreal injection. Some clinicians may prescribe them in select situations. If you are prescribed drops, use them exactly as directed. Wash your hands thoroughly before putting in any drops.
- Apply prescribed antibiotic drops as instructed if given
- Avoid touching or rubbing your treated eye
- Keep the eye clean and avoid getting soap or water directly in it
- Use preservative-free artificial tears as needed for irritation
- Continue your usual medications unless we specifically instruct otherwise
Most patients can resume normal activities the same day, but you should avoid rubbing the eye and avoid swimming or hot tubs for 24 to 48 hours or per our office protocol. You should also skip eye makeup for at least 24 hours and avoid dusty or dirty environments when possible on the day of your injection. If you have special risk factors, ask us about strenuous exercise or heavy lifting.
- Avoid rubbing or touching your treated eye
- Avoid swimming, hot tubs, or natural bodies of water for 24 to 48 hours
- Avoid eye makeup for at least 24 hours
- Avoid dusty or dirty environments on the day of injection
- Follow any individualized restrictions we provide
We will let you know when to return for your next appointment before you leave. Follow-up timing depends on your treatment plan and the condition we are managing. Some patients return in four weeks, while others may have a different schedule.
Keeping your follow-up appointments is essential for monitoring your response to treatment and adjusting your care plan as needed. Regular visits help us catch any changes early and maintain the best possible vision outcomes.
Recognizing Complications and When to Seek Care
While serious complications from intravitreal injections are uncommon, it is important to understand the potential risks so you know what to watch for. Being aware of these risks helps you recognize warning signs early and seek prompt care if needed.
- Endophthalmitis, a serious infection inside the eye
- Sterile inflammation or uveitis-like reaction
- Retinal tear or retinal detachment
- Vitreous hemorrhage or bleeding inside the eye
- Transient or sustained increase in intraocular pressure
- Cataract progression or lens injury, though rare
- Systemic risks such as thromboembolic events are very rare but may be a consideration if you have specific risk factors
Certain symptoms require urgent evaluation. If these occur, do not wait for a scheduled visit. You may need same-day evaluation. Contact our office or seek emergency care right away if you experience sudden vision loss, severe eye pain that does not improve, or seeing flashes of light or a curtain across your vision.
- Sudden decrease in vision or new blind spots
- Severe pain that worsens or does not respond to over-the-counter pain relief
- Increasing redness, discharge, or swelling after the first day
- Sensation of flashing lights or a shadow in your peripheral vision
- Worsening light sensitivity with increasing redness and decreasing vision
- New nausea or vomiting with severe eye ache or headache, which may indicate high eye pressure
- A sudden shower of new floaters or a curtain or shadow that does not clear
- Any symptom that causes you significant concern
Many sensations after an injection are normal and do not signal a problem. Mild scratchiness, slight redness, floaters that gradually improve, and temporary blurry vision are all expected. Seeing a small spot of blood on the white of your eye is also common and usually harmless.
These symptoms should improve over the first few days. If they persist beyond a few days or get worse instead of better, let our office know so we can evaluate your eye.
We want you to feel comfortable reaching out if you have any questions or worries after your injection. It is always better to call and check than to wait and wonder if something is wrong. Our team can help you determine whether you need to be seen urgently or if your symptoms are part of normal healing.
When you call, be ready to describe your symptoms, when they started, and whether they are getting better or worse. This information helps us give you the best advice over the phone.
Frequently Asked Questions
We generally recommend arranging for someone to drive you home because your vision may be blurry for several hours after the injection. Even though only one eye is treated, the temporary vision changes can make driving unsafe, and you may have dilating drops that affect your sight.
Most patients do not find injections become more painful over time, though dryness, irritation, or anxiety can affect comfort. Many actually feel less anxious with each visit as they know what to expect. Let us know if your comfort changes from one visit to the next so we can adjust our anesthesia and technique to better meet your needs.
The floaters you notice are typically small air bubbles or the medication itself moving through the vitreous in your eye. These are harmless and will dissolve or settle out of your line of sight within a day or two as the medication disperses. Keep in mind that a sudden increase in floaters, especially if accompanied by flashes or a shadow, is different and should prompt a call to our office.
The total number of injections varies widely depending on your diagnosis and how your eye responds to therapy. Some patients need ongoing treatment for years, while others may eventually take breaks between injections. We tailor your treatment plan based on your individual progress and imaging results.
You should avoid wearing contact lenses for at least 24 hours after your injection, or until any redness or irritation has resolved. We will let you know when it is safe to resume wearing your contacts based on how your eye is healing.
