Suturless Vitrectomy

 

 

What is Vitrectomy ?

Any surgery done for treating a disease of the vitreous or retina involves removal of the vitreous gel and is called “Vitrectomy”. The slitvitreous can be reached only by making cuts in the walls of the eye.

 

What is SUTURELESS vitrectomy ?

Recently, a new method of performing vitrectomy has been invented and is becoming popular all over the world. Similar to the developments in Cataract surgery, even Vitrectomy can be done with a “sutureless” approach! and it’s done by allon accurus sutureless vitrectomy machine. This requires the use of special equipment that enables the surgeon to reach the vitreous using cuts that are as small as 0.5mm. These cuts close automatically and DO NOT require sutures.

Humphery Perimetry (Field Analyzer) – Zeiss

 

A visual field test is an eye examination that can detect dysfunction in central and peripheral vision which may be caused by various medical conditions such as glaucoma, stroke, brain tumours or other neurological deficits. Visual field testing can slitbe performed clinically by keeping the subject’s gaze fixed while presenting objects at various places within their visual field. The exam may be performed by a technician in one of several ways. The test may be performed by a technician directly, with the assistance of a machine, or completely by an automated machine.

OCT – OptopVUE

 
slit

Optical  Coherence Tomography (OCT) is a non-contact medical imaging technology similar to ultrasound and MRI. With OCT, reflected light is used to produce detailed cross-sectional and 3D images of the eye.

 

With OCT, each of the retina’s distinctive layers can be seen, allowing your ophthalmologist (Eye M.D.) to map and measure their thickness. These measurements help with early detection, diagnosis and treatment guidance for retinal diseases and conditions, including age-related macular degeneration and, diabetic eye disease, among others.

 

In addition, OCT is often used to evaluate disorders of the optic nerve. The optic nerve is made up of many nerve fibers and sends signals from your retina to your brain, where these signals are interpreted as the images you see. The OCT exam is helpful in determining changes to the fibers of the optic nerve, such as those caused by glaucoma.

 

What happens during OCT?

Once your eyes are dilated, you will be seated in front of the OCT machine and will rest your head on a support to keep it motionless. The equipment will then scan your eye without touching it. Scanning takes about 10 to 15 minutes. Afterwards, your eyes may be sensitive to light for several hours from being dilated.

 

 

 

What conditions can OCT help to diagnose?

Optical coherence tomography (OCT) is useful in diagnosing many eye conditions, including :

• Macular hole;

• Macular pucker;

• Macular edema;

• Age-related macular degeneration;

• Central serous retinopathy;

• Diabetic retinopathy;

• Preretinal membranes.

FFA (Flouroscein Angiography) – Topcon

slit

 

Fundus Fluorescein angiography (FFA)

 

Fluorescein angiography is an eye test that uses a special dye and camera to look at blood flow in the retina and choroid, the two layers in the back of the eye.

 

How the Test is Performed ?

Eye drops that make the pupil dilate will be given. You will be asked to place your chin on the camera’s chin rest and your forehead against a support bar to keep your head still during the test.

 

The health care provider will take pictures of the inside of your eye. After the first group of pictures are taken, a dye called fluorescein is injected into a vein, usually at the bend of your elbow. Then, a special camera takes pictures as the dye moves through the blood vessels in the back of your eye.

 

Why the Test is Performed ?

This test is done to see if there is proper blood flow in the blood vessels in the two layers in the back of your eye (the retina and choroid).

How to Prepare for the Test

You will need someone to drive you home, because your vision may be blurred up to 12 hours after the test.

 

You may be told to discontinue drugs that could affect the test results. Tell your health care provide about any allergies, particularly reactions to iodine.

 

You must sign an informed consent form. You must remove contact lenses before the test. Tell the health care provider if you may be pregnant.

Green Laser – Iridex

slit

Retinal Photocoagulation Lasers are used to treat a variety of eye diseases including the two leading causes of blindness in the United States: Diabetic Retinopathy and Age-related Macular Degeneration. This precision laser can lower the risk of vision loss by cauterizing ocular blood vessels. Two types of Photocoagulation Lasers are used for conditions like Diabetic Retinopathy. The first is Focal Photocoagulation, which treats specific leaking blood vessels in the retina. The second is Scatter or Pan-retinal Photocoagulation; this type is used for more widespread damage over the retina. The risk of using a Retinal Photocoagulation Laser are low and side effects are rarely severe. Retinal Photocoagulation Lasers are often combined with other lasers to encompass a multitude of Ophthalmological surgical procedures. Deciding on which Retinal Photocoagulation Laser or combination laser for your practice depends on practice size, common procedures, patient dynamics as well as monetary investment.

Mannual A-Scan – Biomedix

slit

 

A-scans are also extremely beneficial in cataract surgeries, as they enable the Opthalmologist to determine the power of the intraocular lens (IOL) needed for the artificial implant. In Cataract surgery, the cloudy natural lens is removed from the eye. In most cases, the focusing power of the natural lens is restored by replacing it with a permanent intra ocular lens (IOL) implant. In connection with this, the power of the intra ocular lens should be determined.

Autorefractometer – Topcon & Nidek

slitslit

 

Refractometry is a method of measuring the eye’s refraction. For this examination, the ophthalmologist employs a computer-assisted instrument called an Automatic Refractometer. With the help of this instrument the optometrist can give glass prescription to the patient.

Non Contact Tonometer – Topcon & Nidek

Tonometry is the procedure eye care professionals perform to determine the intraocular pressure (IOP), the fluid pressure inside the eye. It is an important test in the evaluation of patients at risk from glaucoma

Lensometer – Topcon

slit

 

A lensmeter or lensometer, also known as a focimeter or vertometer, is an ophthalmic instrument. It is mainly used byoptometrists and opticians to verify the correct prescription in a pair of eyeglasses, to properly orient and mark uncut lenses, and to confirm the correct mounting of lenses in spectacle frames. Lensmeters can also verify the power of contact lenses, if a special lens support is used.

Slit Lamp with Digital Camera – Topcon

slit

 

The slit lamp is an instrument consisting of a high-intensity light source that can be focused to shine a thin sheet of light into the eye. It is used in conjunction with a biomicroscope. The lamp facilitates an examination of the anterior segment and posterior segment of the human eye, which includes the eyelid, sclera, conjunctiva, iris, natural crystalline lens, and cornea. Diseases of the eye can be difficult to diagnose during a general physical examination. A doctor who specializes in treating eye problems (ophthalmologist) is better able to examine and diagnose these conditions because the tools he or she has are specific to the eyes. When you have an eye check-up, you will likely undergo a slit lamp exam. With the help of latest Slit lamp with digital Camera by Topcon, we can click anterior & posterior eye images of different disease. Some of them are as follows: – Cataract in human eye: magnified view seen on examination with the slit lamp

What Does this Exam Help Diagnose?

A slit lamp exam can aid in diagnosing the following:

  • macular degeneration—chronic condition affecting the macula, which is the tissue on the eyeball’s inside back wall
  • detached retina—when the retina, which is an important layer of tissue at the back of the eye, becomes detached from the blood vessels that nourish it
  • cataracts—clouding of the lens that negatively affects the ability to see
  • injury to the cornea—an injury to the tissue that covers the front of the eye
  • blockages of the retinal vessel—obstructions in the eye’s blood vessels that can cause loss of sight

A Yag capsulotomy is a special laser treatment used to improve your vision after cataract surgery. It is a simple, commonly performed procedure which is very safe. During your cataract operation, the natural lens inside your eye that had become cloudy was removed YAG lasers are used in ophthalmology to correct posterior capsular opacification, a condition that may occur after cataract surgery. Why the Yag Laser capsulotomy to be perform ? Posterior Capsule Opacity – A Common Cataract Surgery Complication One of the most common cataract surgery complications is a posterior capsule opacity (also called posterior capsule opacification or PCO). Although some people call PCO a “secondary cataract,” it really is not a cataract. Once a cataract is removed, it does not come back. Some of the patient may get the PCO after a Cataract Surgery and this kind of patient may treated by the YAG Laser Capsulotomy and it is done in OPD.
