Laser Iridotomy Surgery in India | Effective Treatment for Glaucoma

Laser Iridotomy surgery is a specialized procedure used to treat or prevent angle-closure glaucoma, a serious eye condition caused by increased pressure in the eye. The surgery involves creating a small hole in the iris using a laser, allowing fluid to drain more effectively and reducing intraocular pressure. India is a leading destination for Laser Iridotomy, offering world-class ophthalmic care at affordable prices. Renowned eye hospitals in cities like Delhi, Chennai, and Mumbai are equipped with advanced technology and staffed by highly experienced ophthalmologists.

Patients benefit from precise treatment, quick recovery, and comprehensive post-surgery care.

LASER IRIDOTOMY SURGERY IN INDIA

What is a Laser Iridotomy

Closed-angle (of pupillary-block) glaucoma is one of many types of glaucoma. Often it can be cured through a procedure called an iridotomy. To better understand closed-angle glaucoma and its treatment, iridotomy . it is important to understand the different factors which determine eye pressure.

In laser iridotomy, a small hole is placed in the iris (the colored portion of the eye). In most patients, the iridotomy is placed in the upper portion of the iris and cannot be seen under the upper eyelid.

What is eye pressure?

Aqueous humor (the nourishing fluid within the front of the eye) leaves the eye through a tiny drain called the trabecular meshwork.

Aqueous humor leaves the eye through a tiny drain called the trabecular meshwork, which is located just in front of the iris.

The trabecular meshwork is located on the side of the eye, just in front of the iris (the part which gives an eye color). Since the fluid is made just behind the iris, it must pass between the iris and lens before leaving through the trabecular meshwork.

The balance between how much fluid is made, and how much leaves the eye, determines the pressure within the eye. All eyes have measurable pressure. However, when the amount of aqueous humor draining from the eye is reduced, the pressure within the eye can increase. This high pressure often leads to glaucoma.

Although many people think of glaucoma as just one single disease, in fact there are many different forms of glaucoma. Differences depend upon where in the eye the blockage to the drainage occurs. Both the border between the iris and lens as well as the trabecular meshwork are areas where the flow of aqueous can be limited, leading to increased eye pressure. One type of glaucoma, pupillary-block glaucoma, occurs with the former. In this type of closed-angle glaucoma, the flow of fluid between the iris and lens is blocked . It is called pupillary-block glaucoma because the fluid is trapped behind the pupil.

Pupillary-Block Glaucoma Surgery in india

The blockage of fluid flow between the iris and lens can cause the pressure behind the iris to rise. As it rises, the iris is pushed forward. If it moves forward enough, the iris can cover trabecular meshwork like a rubber stopper in a drain.
Sometimes a patient is unaware of the pupillary-block. However, the eye may become red. A patient also may experience headache or pain, blurred vision, and halos around lights. Rarely, there is nausea.

If there is sudden pupillary-block and if the eye is left untreated, permanent damage can occur which can lead to blindness.

The sooner the blockade of fluid flow between the border of the iris and lens is treated, the less damage occurs. Therefore, it is desirable to treat this disease as early as possible.

The best treatment for pupillary-block glaucoma is to create a hole in the iris (known as an iridotomy)). The iridotomy allows the flow of fluid to the front of the eye to be restored, bypassing the pupil, the location of the blockade.

(Laser iridotomy) The hole in the iris is known as an iridotomy. The iridotomy allows the flow of fluid to the front of the eye to be restored.

Final hole in iris to release pressure in eye. With fluid passing through the iridotomy, the iris is no longer pushed forward. Fluid can leave the eye through the trabecular meshwork again.

How do lasers work to treat glaucoma?

Lasers deliver a type of light energy. This type of light energy is similar to using a magnifying glass to harness the energy of the sun to burn a hole in a piece of paper on a sunny day. The magnifying glass needs to properly focus the light to create a hole in the paper. Likewise, if the laser is not aimed properly at the iris, there is no effect. In order to focus the laser, your eye doctor uses an instrument called a slit-lamp.

This is the same instrument which is used to routinely examine your eyes. Since this is actually a type of microscope, the laser energy can be focused with extreme accuracy.

Several types of lasers can be used to treat pupillary-block glaucoma. The use of the argon laser to create an iridotomy was accepted widely by 1980. Since then, another type of laser, the neodymium: YAG laser, also has proven to be safe and effective. Although there are some differences between these two types of lasers, the use of one or another is best left to your ophthalmologist.

How is laser iridotomy performed?

Before having an iridotomy, your ophthalmologist may place some different types of drops on your eye. The first drop, pilocarpine, will make your pupil smaller. This stretches and thins your iris, similar to stretching out the top surface of a drum. By doing this, it is easier for the laser to penetrate and make a hole in your iris. You may be asked to continue using this eye drop for a few days following the laser treatment. This medication may temporarily cause blurred vision (especially at night) and also may give you a brow-ache.

Another type of eye drop may be used within a few hours of your laser treatment to prevent eye pressure from increasing following laser treatment, or to treat and eye pressure that already has increased. Still other eye drops may be used to reduce inflammation.

The only kind of anesthesia required to perform a laser iridotomy is an eye drop (Figure 5). This is the same type of drop which your doctor places in your eye when the eye pressure is measured. With the eye drop, the laser surgery should be painless. You may see a bright light, like a photographer’s flash from a close distance. Also, you may feel a pinch-like sensation.

The only anesthesia required to perform a laser iridotomy is an eye drop.

Your doctor will next place a special contact lens on your eye to focus the laser light upon the iris (Figure 6). This lens keeps your eyelids separated so that you do not blink during the treatment. This also reduces small eye movements so that you do not have to worry about your eye moving during the treatment. To protect the eye from being scratched by the contact lens, special jelly is placed on its surface. This jelly may remain on your eye for about 30 minutes, leading to blurred vision or a feeling of heaviness.

A special contact is placed on your eye to focus the laser upon the iris.

What to expect after an iridotomy.

After treatment, your doctor may ask you to stay for a few hours to check your eye pressure and insure that it has not increased.
When it is safe, you will be sent home and may be asked to use eye drops. Your ophthalmologist will explain their use and when you need to be examined again.

In general, there are no restrictions in activity following the laser treatment. You can return to your normal daily chores immediately. It is advisable to have someone drive you home from your doctor’s office. You can expect some redness of the eye, a sensitivity to light, and a scratchy sensation. All of these might last for a period of days. You also might expect a small headache later that day or night.
