Treatments for diabetic retinopathy are generally designed to be as comfortable as possible through the use of local anaesthetics, but they can involve various levels of discomfort. In the United Kingdom, NHS specialists prioritize patient comfort during procedures like laser therapy and eye injections by using numbing drops or occasionally small anaesthetic injections. While “pain” is rarely the primary experience, many patients describe the treatments as involving unusual sensations, such as a “dull ache,” “sharp pricking,” or a feeling of “pressure.” Understanding what to expect during each procedure can help reduce anxiety and allow you to prepare for the post-treatment recovery period.

Sensation During Laser Treatment (PRP)
Retinal laser treatment, particularly Pan-Retinal Photocoagulation (PRP), is typically described as uncomfortable rather than agonizingly painful. Before the procedure, you will receive numbing drops to ensure the contact lens used by the doctor does not cause pain on the surface of the eye.
As the laser is applied, you may experience:
- Bright Flashes: The visual experience can be very intense and “dazzling.”
- Dull Aches or “Thuds”: Many patients describe a sensation like a tiny, rhythmic “thud” inside the eye.
- Sharp Pricks: Occasionally, the laser hits a nerve under the retina, causing a brief, sharp pricking feeling. Specialists at Royal Berkshire Hospital advice that you should inform them if you feel this, as they can adjust the laser settings to make it more tolerable.
Comfort Levels During Eye Injections
The idea of an injection into the eye can be daunting, but most UK patients report that the procedure is much less painful than they anticipated. The surface of the eye is thoroughly numbed with anaesthetic drops before the injection.
The actual experience of an anti-VEGF injection usually involves:
- A Pressure Sensation: You may feel a brief “push” or “pressure” as the medication is administered, but you rarely feel the needle itself.
- A Quick Procedure: The injection takes only a few seconds.
- Post-Injection Grittiness: For a few hours after the procedure, your eye may feel “sandy” or “gritty.” This is often due to the antiseptic cleaning solution used to prevent infection. According to Addenbrooke’s Hospital, lubricating drops or simple paracetamol are usually sufficient to manage this temporary discomfort.
Recovery After Vitrectomy Surgery
A vitrectomy is a more significant operation, but it is almost always performed under local or general anaesthesia, meaning you will feel no pain during the surgery. The discomfort typically begins during the recovery phase.
Common post-operative sensations include:
- Redness and Swelling: The eye will look quite bruised and red for several days.
- A “Scratching” Feeling: This is often caused by the tiny stitches or the healing incisions.
- Aching and Nausea: If a gas bubble is used, the changes in eye pressure can sometimes lead to a dull headache or a feeling of nausea.
University Hospitals Coventry & Warwickshire clinical leaflets suggest that “severe pain” is unusual after a vitrectomy. If you experience intense, throbbing pain that is not relieved by paracetamol, it is considered a red flag that requires an urgent review by the eye department.
Managing Discomfort at Home
If you have undergone a lengthy laser session or surgery, it is common to develop a headache or a “heavy” feeling in the eye once the anaesthetic wears off. UK healthcare providers recommend several simple steps to maintain comfort:
- Simple Analgesia: Paracetamol or ibuprofen are usually very effective for post-treatment aching. You should follow the standard dosage advice on the packet.
- Dark Glasses: Because your pupils are dilated for most treatments, your eyes will be extremely sensitive to light. Bringing sunglasses to your appointment can significantly reduce the discomfort of the journey home.
- Rest: Allowing yourself to rest in a darkened room for a few hours after treatment helps the “dazzle” from the laser or the blurring from the drops to settle more comfortably.
| Treatment | During the Procedure | Post-Procedure Recovery |
| Laser (PRP) | Bright lights, dull thuds | Dazzled, mild headache |
| Eye Injections | Brief pressure sensation | Gritty, watery eye (few hours) |
| Vitrectomy | None (Anaesthesia used) | Aching, “scratched” feeling |
| Screening | None | Temporary blur from drops |
Conclusion
While treatments for diabetic retinopathy can be uncomfortable and involve unusual sensations like pressure or a dull ache, they are rarely described as acutely painful. The use of modern numbing drops and anaesthetics ensures that the procedures are tolerable for many patients. Most discomfort is temporary and can be managed effectively with sunglasses and over-the-counter painkillers. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Can I have a general anaesthetic for laser treatment?
Generally, no. Laser is a quick outpatient procedure that only requires numbing drops. However, for patients who are extremely anxious or have a severe needle phobia, a subconjunctival anaesthetic (a small injection under the white of the eye) can be used.
Why does my eye feel “sandy” after an injection?
This is a very common side effect of the iodine or antiseptic used to clean the eye. It usually disappears within 24 hours. Using lubricating drops (artificial tears) can help.
Is it normal to have a headache after retinal laser?
Yes. The combination of the bright light and the concentration required can often lead to a dull headache. Paracetamol usually resolves this quickly.
Will the doctor stop if I feel pain?
Yes. If you feel a sharp pain during the laser, tell the doctor. They can often change the angle or power of the laser to avoid hitting a nerve.
Does a gas bubble in the eye hurt?
The bubble itself doesn’t hurt, but it can cause your eye pressure to change, which might result in a “heavy” or “aching” feeling in the eye.
Should I take painkillers before my appointment?
Many UK clinics suggest taking paracetamol an hour before a lengthy laser session to help stay relaxed and manage any subsequent aching.
Is there a risk of permanent pain?
No. While the treatments can be uncomfortable, they do not cause chronic, long-term pain. Any discomfort felt is a normal part of the healing and recovery process.
