Yes, eye injections can help save vision and prevent further sight loss in conditions such as wet age-related macular degeneration (AMD), diabetic macular edema, diabetic retinopathy, and retinal vein occlusion. An eye injection, or intravitreal injection, delivers medication directly into the vitreous cavity of the eye to treat retinal conditions like wet macular degeneration, diabetic eye disease, and retinal vein occlusion. The eye is numbed beforehand, the injection itself takes seconds, and most patients feel pressure rather than pain. Vision may be blurry for a few hours, but normal activity usually resumes the same day.

Eye Injections Explained: What Patients Need to Know
Most patients freeze the moment they hear the word “injection” and “eye” in the same sentence. It sounds worse than it is. I have given thousands of these injections, and the fear almost always outweighs the actual experience.
Eye injections, more precisely called intravitreal injections, are one of the most effective treatments we have for conditions that used to cause permanent vision loss. They treat wet macular degeneration, diabetic macular edema, and retinal vein occlusion, among other conditions. Done correctly, the procedure takes under two minutes and most patients say the anticipation was worse than the injection itself.
This article explains what an eye injection actually involves, why it is needed, what you will feel, and what recovery looks like. My goal is for you to walk into your first appointment informed, not anxious.
Why Eye Injections Are Given
| Condition | What It Means | What To Do About It |
|---|---|---|
| Wet age-related macular degeneration | Abnormal blood vessels leak fluid under the retina, distorting central vision | Start anti-VEGF injections promptly; delays beyond a few weeks can cause permanent central vision loss |
| Diabetic macular edema | High blood sugar damages retinal vessels, causing fluid to pool in the macula | Combine injections with strict blood sugar control monitored with your endocrinologist |
| Retinal vein occlusion | A blocked retinal vein causes fluid backup and swelling in the retina | Get injections started within days of diagnosis to limit permanent damage |
| Diabetic retinopathy with new vessel growth | New, fragile blood vessels form and can bleed into the eye | Anti-VEGF injections plus laser treatment are often used together |
| Post-surgical or post-uveitis inflammation | Inflammation inside the eye causes swelling that threatens vision | Steroid injections reduce inflammation faster than drops alone in select cases |
| Myopic choroidal neovascularization | High myopia triggers abnormal vessel growth similar to wet AMD | A short course of anti-VEGF injections usually controls this well |
What Happens During the Injection
| Step | What It Means | What To Do About It |
|---|---|---|
| Numbing drops | Anesthetic drops are applied to the eye surface 10-15 minutes before the injection | Arrive on time so the numbing has full effect; do not rub your eye afterward |
| Antiseptic prep | The eye and surrounding skin are cleaned with a povidone-iodine solution to prevent infection | Tell your doctor immediately if you have an iodine allergy |
| The injection itself | A very fine needle delivers medication into the vitreous cavity in one to two seconds | Keep your eye still and fixed on the target light your doctor points to |
| Immediate aftercare | Antibiotic drops may be prescribed and a protective check is done | Ask for written instructions before leaving the clinic |
| Same-day vision | Vision is often blurry or has floating spots for a few hours | Arrange for someone to drive you home if you feel uneasy about this |
| Follow-up scheduling | Most conditions need repeated injections on a defined schedule, not just one | Keep every follow-up appointment; skipping doses reduces effectiveness significantly |
Is an Eye Injection Painful
No, eye injections are not painful. Most patients describe a sensation of pressure or a brief cold feeling, not sharp pain. Because the eye surface is numbed thoroughly beforehand, the needle itself is rarely felt. Some mild soreness or grittiness for a day afterward is normal and expected.
I tell every patient the same thing before their first injection. The anticipation in the waiting room is almost always harder than the thirty seconds that follow.
When To See a Doctor
Contact your ophthalmologist immediately if you notice any of the following after an eye injection:
- Sudden or worsening pain, rather than mild soreness, more than a day after the injection
- Redness that increases instead of fading over 24 to 48 hours
- A sudden drop in vision, or new flashes and floaters that were not there before
- Sensitivity to light that feels significantly worse than usual
- Discharge, crusting, or any sign of infection around the eye
- Fever or feeling generally unwell alongside eye symptoms
- Any of these symptoms in a child receiving eye injections for conditions like retinopathy of prematurity
These signs can, in rare cases, point to infection or retinal detachment, both of which need same-day evaluation.
Caring for Your Eye After the Injection
- Avoid swimming pools and hot tubs for at least three days to reduce infection risk
- Skip eye makeup on the treated eye for 24 hours
- Do not rub the eye, even if it feels gritty or irritated
- Use only the drops your doctor prescribes, at the schedule given
- Resume normal reading and screen use as soon as the blurriness clears, usually within a few hours
- Avoid heavy lifting or strenuous exercise for the rest of the day as a precaution
Types of Eye Injections
Anti-VEGF Injections
These are the most commonly used eye injections today. They block a protein called vascular endothelial growth factor, which drives abnormal blood vessel growth and leakage. Common examples include ranibizumab, aflibercept, and bevacizumab. Most patients need injections monthly at first, tapering to longer intervals once the disease stabilizes.
Steroid Injections
Steroid injections reduce inflammation more powerfully than drops in certain cases, such as diabetic macular edema that has not responded to anti-VEGF therapy, or inflammation following uveitis. They carry a higher risk of raised eye pressure and cataract formation, so I monitor these patients more closely, particularly if they already carry a glaucoma diagnosis. [Glaucoma Hub]
How Many Injections Will I Need
This depends entirely on the underlying condition and how your eye responds. Wet macular degeneration often needs three loading doses a month apart, followed by injections every one to three months based on monitoring. Diabetic macular edema and retinal vein occlusion follow a similar pattern, adjusted to your OCT scans and vision response at each visit.
Frequently Asked Questions
Are eye injections safe?
Yes, intravitreal injections have an excellent safety record when performed under sterile conditions by a trained ophthalmologist. Serious complications like infection occur in fewer than 1 in 2,000 injections. The benefit of preserving vision in conditions like wet macular degeneration far outweighs this small risk.
Will I be awake during the injection?
Yes, the procedure is done with topical numbing drops or gel, not general anesthesia. You will be awake and aware, but the eye surface is numbed so you should not feel sharp pain. Most patients are surprised by how quickly it is over.
Can I drive myself home after an eye injection?
Many patients do drive themselves, since only the treated eye may be temporarily blurry. If both eyes are treated on the same day, or you feel anxious about vision quality afterward, arranging a ride is the safer choice.
How much do eye injections cost in Gurgaon?
Cost varies depending on the specific medication used, since anti-VEGF drugs range widely in price, and on whether multiple injections are planned. I discuss the full cost and treatment schedule with every patient during consultation, before starting treatment.
What happens if I skip a scheduled injection?
Skipping doses allows the underlying leakage or swelling to return, which can undo previous gains and, in some cases, cause new permanent damage. If you must reschedule, contact the clinic as early as possible rather than skipping the appointment entirely.
Do eye injections hurt more with repeated use?
No, most patients report that later injections feel easier than the first, mainly because the anxiety around the unknown has passed. The physical sensation itself does not become more painful with repetition.
Key Takeaways
- Eye injections treat serious retinal conditions like wet macular degeneration, diabetic macular edema, and retinal vein occlusion

- Most patients feel pressure, not pain, and describe the anticipation as harder than the procedure
- Vision may blur for a few hours; plan for this on the day of your appointment
- Watch for worsening pain, redness, or vision loss after 24 hours, and seek same-day care if these appear
- Sticking to your full injection schedule is essential; skipping doses can reverse progress
