Context:

The Department of Ophthalmology at Army Hospital (Research and Referral), New Delhi became the first in the Armed Forces to perform minimally invasive glaucoma surgery (MIGS) using an advanced 3D microscope system.

About 3D Microscopy

Unlike traditional microscopes, which provide a 2D view, this system creates a three-dimensional image of the eye.

Surgeons wear special 3D polarization glasses and view the procedure on a 55-inch 4K ultra-HD screen, which offers incredible clarity and depth. This setup allows them to see small details inside the eye more clearly, making surgeries more accurate.

About Glaucoma

Glaucoma is an eye condition that damages the optic nerve, often due to abnormally high pressure in the eye (intraocular pressure). It is one of the leading causes of irreversible blindness worldwide and is particularly prevalent among aging populations.

Traditional glaucoma surgeries like trabeculectomy are effective but carry significant risks and complications. Minimally Invasive Glaucoma Surgery (MIGS) represents a newer approach that offers:

Reduced surgical trauma
Faster recovery times
Lower risk profile compared to traditional surgeries
Potential for combining with cataract surgery in appropriate cases
Less postoperative care requirements

MIGS procedures target different outflow pathways to reduce intraocular pressure with minimal tissue disruption. The precision required for these procedures makes the enhanced visualization of 3D microscopy particularly valuable.

The 3D system has several advantages:

Faster surgeries: Doctors complete procedures more quickly because they can see better.
Fewer complications: The precision reduces the risk of mistakes or damage.
Less light exposure: The system uses a lower-power endoilluminator (a light source), which reduces “photo-toxicity” (harm to the eye from bright light).
Ease in complex cases: It is especially helpful for tricky surgeries, like those involving patients with unusual eye conditions or physical challenges (e.g., severe kyphosis, a spinal condition).
High satisfaction: Surgeons and nurses find it easier and more comfortable to use, improving their efficiency.
