Insights Shared by Prof. Deepak Agrawal on Advanced Eye Cancer Treatment
Eye cancer can become one of the most difficult conditions for both patients and doctors. In many traditional treatment methods, removing the cancer may sometimes also require removal of the eye itself, which can permanently affect vision and quality of life. During a medical discussion, Prof. Deepak Agrawal explained how Gamma Knife technology (focused radiation treatment) is helping doctors treat selected eye cancers without major surgery.
According to the discussion, All India Institute of Medical Sciences (AIIMS Delhi) has started using advanced Gamma Knife Radiosurgery (highly precise radiation treatment) techniques for certain eye tumors, making it possible in some cases to preserve both the eye and vision.
What Happens in Eye Cancer?
Doctors explained that tumors (abnormal growth of cells) develop when cells inside the body begin growing uncontrollably. When these tumors occur inside the eye, treatment becomes extremely challenging because the structures responsible for vision are delicate and highly sensitive.
In many advanced cases, traditional surgery may require removal of the affected eye to control the cancer. This can lead to permanent vision loss and major emotional stress for patients and families.
Gamma Knife Therapy: A Non-Invasive Treatment Option
Prof. Deepak Agrawal explained that Gamma Knife is a highly precise form of stereotactic radiosurgery (targeted radiation treatment) that uses focused radiation beams to target tumors without large surgical cuts.
According to him:
- Gamma Knife treatment does not require major surgery
- The treatment is highly precise
- Nearby healthy tissues receive minimal radiation exposure
- In selected cases, vision may be preserved
- Many patients can return home the same day
He also clarified that despite the word “knife” in its name, Gamma Knife does not involve any blade or cutting. The name refers to the precision of the treatment.
Why Gamma Knife Is Important for Eye Tumors
Some eye tumors are located very close to the optic nerve (vision nerve) or are too large for certain conventional treatments. In such situations, Gamma Knife Radiosurgery may become an important treatment option.
Prof. Agrawal explained that Gamma Knife delivers multiple focused radiation beams toward the tumor with extremely high accuracy. This helps doctors target cancer cells while reducing unnecessary exposure to nearby healthy tissues.
He also mentioned that the system works with sub-millimeter precision (extremely high accuracy), making it suitable for delicate organs such as the brain and eyes.
How the Procedure Is Performed
Doctors explained that treatment usually involves teamwork between ophthalmologists (eye specialists) and neurosurgeons (brain and nerve surgeons).
The process generally includes:
- Local anesthesia (numbing medicine) for comfort
- Stabilization of eye muscles
- Placement of a stereotactic frame (support frame for precision)
- Detailed MRI or CT imaging
- Treatment planning using specialized software
- Focused Gamma Knife radiation delivery
Prof. Agrawal explained that the Gamma Knife system uses more than 200 focused radiation beams directed toward a carefully planned target area.
Because the treatment is non-invasive (without major surgery), large cuts are usually avoided.
AIIMS Delhi’s Experience With Gamma Knife Eye Cancer Treatment
According to Prof. Deepak Agrawal, AIIMS Delhi has been using Gamma Knife treatment for eye cancers over the last few years.
He explained that:
- This treatment is available only at limited centers in India
- AIIMS Delhi became one of the early institutions in the country to use this technology for selected eye tumors
- Early treatment outcomes have been encouraging

The discussion also mentioned that around 80% tumor control was observed in treated patients during early follow-up experiences.
Same-Day Treatment and Faster Recovery
One major advantage highlighted during the discussion was convenience and faster recovery.
According to Prof. Agrawal:
- Many patients can complete treatment within a single day
- Long hospital stays are often unnecessary
- Recovery is usually faster compared to open surgery
- No large incision (surgical cut) is required
This makes the treatment especially valuable for selected patients who wish to avoid major surgery.
Cost and Accessibility
Prof. Agrawal also discussed treatment accessibility in India.
According to him:
- Government-supported treatment costs have remained stable for years
- Ayushman Bharat beneficiaries may receive support
- BPL patients may also receive financial assistance in some cases
He emphasized that advanced medical technology should become accessible to patients who genuinely need it.
Growing Need for Early Detection
Doctors participating in the discussion explained that eye cancers such as choroidal melanoma (a type of eye tumor) are increasingly being detected in younger age groups in India.
According to experts:
- Regular eye check-ups are important
- Early diagnosis improves treatment planning
- Delayed detection may increase complications
- Follow-up monitoring remains important even after treatment
The Future of Non-Surgical Eye Cancer Treatment
Prof. Deepak Agrawal described Gamma Knife Radiosurgery as an important advancement in precision-based cancer treatment.
According to him, this technology represents a shift toward:
- Non-invasive cancer therapy (treatment without major surgery)
- High-precision radiation treatment
- Organ-preserving treatment approaches
- Faster recovery for selected patients
As medical technology continues evolving, Gamma Knife therapy may become increasingly important for treating tumors located near sensitive organs such as the eyes and brain.
About Prof. Deepak Agrawal

What is Gamma Knife treatment?
Gamma Knife is an advanced radiation treatment (focused ray treatment) used for certain brain and eye tumors without doing a major operation.
Is Gamma Knife a real surgery?
No. Gamma Knife is not a traditional surgery. There are no big cuts, stitches, or heavy bleeding like normal operations.
Does Gamma Knife treatment hurt?
Usually the treatment itself is painless. Some people may feel mild discomfort during frame placement or injections, but most patients remain comfortable.
