RELEX SMILE AND LASER: Difference Between The Procedures - Lasikdelhi
Introduction
ReLEx SMILE and Lasik surgery are effective methods for correcting the eyesight. Both procedures allow the patients to get rid of glasses and contact lenses. There are certain differences between these procedures.

Lasik Eye Surgery
Lasik eye surgery is one of the preferred surgical interventions for treating myopia, hyperopia, and astigmatism. Lasik stands for Laser-Assisted In-situ Keratomileusis. The Lasik eye surgery is safe and effective in managing the eyesight. The surgery lasts for 15-20 minutes, and the patient needs a day to stabilize after the surgery. During the Lasik eye surgery, the doctor creates and lifts a corneal flap, reshapes the corneal tissue, and put the flap back into its original position. Lasik does not cause pain in the eye, and the patient experiences vision correction immediately after the surgery. With sufficient post-operative care, post-operative complications are quite rare.

RELEX SMILE
ReLEx SMILE is a minimally invasive eye surgery to correct myopia, hyperopia, and astigmatism. It is a flapless procedure. ReLEx SMILE stands for Refractive Lenticule Extraction and Small incision lenticule extraction. It is the most recent, advanced, and novel surgery for vision correction. Carl Zeiss Meditec had developed this procedure. The SMILE was previously called Femtosecond lenticular extraction. The surgery is bladeless and stitch-less, and the patient does not experience any pain. It makes use of the femtosecond laser to prepare a 3D map of the eye tissues. This increases the accuracy, safety, and outcome of the procedure.

Difference Between LASIK AND RELEX SMILE
Lasik Eye surgery is currently the trending option for correcting vision problems, while ReLEx SMILE is a novel and advanced procedure. There are differences between both procedures. Some of these differences are:

Procedural difference: Both ReLEx SMILE and Lasik consists of two steps. However, there are certain basic procedural differences. The degree of incision in Lasik is 270 degrees, while in ReLEx SMILE, it is 90 degrees. Lasik comprises creating and lifting the flap on the upper surface of the cornea and reshaping the tissues of the lower layer. The surgeons create a flap because it is highly uncomfortable for the patient if the surgery is done on the first layer due to its high sensitivity. The surgeon reshapes the cornea with the help of an excimer laser.

Unlike a flap formation in Lasik surgery, the ReLEx SMILE comprises the creation of an intrastromal lenticule. For creating the lenticule, the doctor makes two cuts, i.e., posterior refractive cut and anterior cap cut. To get access to this lenticule, the doctor creates a small opening. In the next step, the doctor reshapes the cornea by dissecting and removing the lenticule. ReLEx SMILE provides excellent outcomes due to the use of the wavefront-optimization technique.

Different types of Laser: There is a difference in the type of laser used in ReLEx SMILE and Lasik surgery. ReLEx SMILE only uses a femtosecond laser by Carl Zeiss Meditec, which provides a highly detailed eye mapping. Lasik uses various types of excimer laser or the microkeratome. In some cases, the doctors may also use a femtosecond laser in Lasik.

Recovery time: Recovery time for Lasik and ReLEx SMILE is different for different activities. As the ReLEx SMILE has no cuts and there is no flap formation, the patients with this surgery resume normal activities such as swimming or playing outdoor games within 1-2 days after the procedure. Patient with Lasik surgery requires at least 15 days to a month to resume normal activities. The visual recovery in Lasik surgery is better as compared to ReLEx SMILE. People with Lasik surgery are like to get more comfortable with reading books or working on computer screens earlier in comparison to a patient with ReLEx SMILE procedure.

Scope of treatment: Both Lasik and ReLEx SMILE procedures are safe and effective in treating various eyesight conditions. However, Lasik surgery has a wider scope in treating ocular conditions as compared to ReLEx SMILE. Lasik surgery corrects myopia, hyperopia, and astigmatism. The efficacy of ReLEx SMILE is limited to the correction of myopia and myopic astigmatism. Its efficacy in other conditions is under trial. Lasik surgery may not be an option for people with a thin cornea, while ReLEx SMILE is effective in such cases.

The cost involved: There is a cost difference between the two procedures. ReLEx SMILE is costlier as compared to the Lasik surgery.

Conclusion
ReLEx SMILE and Lasik surgery are safe if performed by the trained surgeons. Some of the basic differences between the two include procedure, types of laser used, cost, and the recovery period.

Dizziness and Vertigo Treatment in Delhi - Dr. Ameet Kishore
Dizziness And Vertigo (Neuro-Otology) Treatment In India
Nowadays issues like Vertigo are very common. But these issues can cause you future problems if not treated well on in time. The condition of Vertigo can be compared to a sensation of movement or turning that is frequently depicted as unsteadiness. Individuals with vertigo feel as if they are turning or moving, or that the world is turning around them.

Epley’s manoeuvre
This is a repositioning manoeuvre used to treat benign paroxysmal positional vertog (BPPV). This move is finished with the help of a specialist or physical advisor. A solitary 10-to 15-minute session, for the most part, is all that is required. At the point when your head is moved into various positions, the canaloliths ( crystals) bringing on vertigo will move openly and don't really bring about manifestations.

Intratympanic Therapy
Direct Injections into the ear via the ear drum are sometimes used to treat certain conditions casuing vertigo and in some types of sudden hearing loss. Gentamicin and steroids can be utilized intratympanically to treat Meniere's disease. This implies they are infused into the tympanum, or middle ear, through the ear drum. This is a minor procedure performed in the out patient. Gentamicin is utilized as a part of patients to stop assaults of vertigo. This can enable the end of enough vestibular cells to stop vertigo attacks without a critical change in hearing.

Endolymphatic sac decompression
This is an operation carried out on the inner ear to control vertigo in patients with Meniere’s disease who do not respond to medication or intratympanic therapy. This operation is implemented in patients with Meniere's ailment to stop or help control the vertigo attacks. It is the main surgery that may preventfurther episodes of vertigo but also keep up the leftover hearing at pre-agent levels. Thesurgeryis done under general anesthesia and takes 1-1.5 hours.

Labyrinthectomy
This is an operation on the inner ear to control intractable vertigo in patients with Meniere’s disease who have very poor residual hearing. The balance endorgan is removed completely and vertigo is controlled at the expense of hearing.

Vestibular nerve section
In this operation the balance nerve is divided while preserving the hearing nerve. This is used to treat intractable vertigo while preserving the hearing.

We have extremely particular and furnished facility for Dizziness and Vertigo Treatment in India. It is the just one of its kind in India and with a broad range of contemporary indicative and restorative equipment and specialized techniques required for the management of dizziness and vertigo.

Retinal Detachment Treatment From Retina Specialist In Mumbai - Dr. Jatin Ashar
Retina Detachment Treatment In Ghatkopar
Eye is made up of Iris, Pupil, Cornea and Retina. The retina is an extremely thin tissue that lines the inside of the back of the eye. It is the light-sensitive portion of the eye. Light from the objects we are looking at, enters the eye. Cornea and the eye lens focus the light image onto the retina. Human eye works like a camera, light striking the retina causes a complex biochemical change within certain layers of the retina and this, in turn, stimulates an electrical response within other layers of the retina.

These electric signals are transmitted by the nerve endings to the brain through optic nerve, which connects the eye to the brain. Within specific areas of the brain, this electrical energy is received and processed to allow us both to see and to understand what we are seeing. The retina has been compared to the film of a camera. However, once used, film has a permanent image on it. The neurosensory retina, in contrast, continually renews itself chemically and electrically, allowing us to see millions of different images every day without them being superimposed.

The retina is about the size of a postage stamp. It consists of a central area called the macula and a much larger peripheral area of the retina. The light receptor cells within the retina are of two types called the cones and the rods. Cones are concentrated within the macular (central) area and provide us with the sharpness of central vision and color vision. Rods predominate in the peripheral area of the retina and allow us to see in conditions of reduced illumination. The peripheral retina allows us to see objects on either side (peripheral vision) and, therefore, provides the vision needed for a person to move about safely.

Retinal Detachment
Retinal detachment occurs when the retina becomes separated from the nerve tissues and blood supply underneath it. While painless, visually this has a clouding effect that has been likened to a gray curtain moving across the field of vision.

There are 3 types of detachment: rhegmatogenous (which involves a retinal break), traction, and serous (exudative) detachment. Traction and serous retinal detachments do not involve a break and are called nonrhegmatogenous.

Rhegmatogenous detachment is the most common type and caused by a tear or hole in the retina. Risk factors include the following:

Myopia
Previous cataract surgery
Ocular trauma
Lattice retinal degeneration
A family history of retinal detachment
Traction retinal detachment can be caused by vitreoretinal traction due to preretinal fibrous membranes as may occur in proliferative diabetic or sickle cell retinopathy.

Serous detachment results from transudation of fluid into the subretinal space. Causes include severe uveitis, especially in Vogt-Koyanagi-Harada disease, choroidal hemangiomas, and primary or metastatic choroidal cancers (see Cancers Affecting the Retina).

Symptoms
A person with a detached retina may experience a number of symptoms.

These include:

Photopsia, or sudden, brief flashes of light outside the central part of their vision, or peripheral vision. The flashes are more likely to occur when the eye moves.
A significant increase in the number of floaters, the bits of debris in the eye that make us see things floating in front of us, usually like little strings of transparent bubbles or rods that follow our field of vision as our eyes turn. They may see what looks like a ring of hairs or floaters on the peripheral side of the vision.
A heavy feeling in the eye
A shadow that starts to appear in the peripheral vision and gradually spreads towards the center of the field of vision
A sensation that a transparent curtain is coming down over the field of vision
Straight lines start to appear curved
Diagnosis
Your doctor may use the following tests, instruments and procedures to diagnose retinal detachment:

Retinal examination. The doctor may use an instrument with bright light and special lenses to examine the back of your eye, including the retina. This type of device provides a highly detailed view of your whole eye, allowing the doctor to see any retinal holes, tears or detachments.
Ultrasound imaging. Your doctor may use this test if bleeding has occurred in the eye, making it difficult to see your retina.
Treatment
The goal of treatment is to re-attach the retina to the back wall of the eye and seal the tears or holes that caused the retinal detachment. Several approaches can be employed to repair a retinal detachment:

Scleral buckle - In this surgery, a silicone band is placed outside the eye wall to push the wall of the eye closer to the retinal tear in order to close the tear. The tear is treated with a freezing treatment to induce controlled scarring around the tear and permanently seal it. The fluid under the retina is sometimes removed at the time of surgery.
Vitrectomy - In this surgery, three small incisions are made in the white part of the eye and fine instruments are manipulated using an operating microscope to remove the vitreous gel that fills the eye and drain the fluid from under the retina. The surgeon may then use a laser or cryopexy to seal the retinal tears or holes. The eye is then filled with a gas bubble to hold the retina in place while it heals.
Pneumatic retinopexy - In this office-based procedure, a gas bubble is injected into the eye and the patient maintains a specific head posture to position the gas bubble over the retinal tear. The tear itself is sealed either with a freezing treatment at the time of the procedure, or with laser after the retina is re-attached.
Laser surgery - In certain cases, a retinal detachment can be walled off with laser to prevent the retinal detachment from spreading. This is generally appropriate for small detachments.
Complications after the surgery
Like any other surgery, retinal detachment procedures can also be followed by complications like:

Allergies to medications
Bleeding in the eye
Double vision
Cataracts
Glucoma
Eye infection
Chance that the retina does not reattach properly
Chance that the retina detaches again
Things to expect after surgery:
You might have some discomfort for a few a days to weeks after surgery. You will be given pain medicine to help you feel better.
You need to rest and be less active after surgery for a few weeks. Your ophthalmologist will tell you when you can exercise, drive or do other things again.
You will need to wear an eye patch after surgery. Be sure to wear it as long as your doctor tells you to.
If a bubble was put in your eye, you will need to keep your head in one position for a certain length of time, such as 1–2 weeks. Your doctor will tell you what that specific head position is. It is very important to follow the directions so your eye heals.
You might see floaters and flashing lights for a few weeks after surgery. You may also notice the bubble in your eye.
Your sight should begin to improve about four to six weeks after surgery. It could take months after surgery for your vision to stop changing. Also, your retina may still be healing for a year or more after surgery. How much your vision improves depends on the damage the detachment caused to the cells of the retina.
