LASIK

UMA EYE CLINIC has been performing Laser Vision Correction for over 2 decades. For the past 10 years we have been associated with Reya Laser Vision Centre, providing state of the art LASER assisted correction of eye powers. One of UMA EYE CLINIC's forte has always been in the forefront of introducing new techniques and technology for the benefit of our patients. We have successfully treated 20,000 patients.

UMA EYE CLINIC was the FIRST to bring the Bausch & Lomb Zyoptix Z100 to Chennai. It ushered the first DUAL BEAM LASER DELIVERY, IRIS PATTERN RECOGNITION, CUSTOM LASIK platform in South East Asia.

The shape of the human cornea has UNIQUE ABERRATIONS similar to a human fingerprint. The human cornea also has optical aberrations which varies from person to person, eye to eye. Customized Laser Correction provides an unique treatment protocol to correct individual eyes.UMA EYE CLINIC has also installed the latest generation custom treatment I DESIGN by VISX. Corneal flaps were initially created with a microkeratome, which is a BLADE to create the corneal flap.

UMA EYE CLINIC In our continuous quest to improve, introduced INTRALASE (FEMTOSECOND LASER) which creates a corneal flap without using a blade. This BLADE-LESS technology is currently approved by NASA, US Navy. UMA EYE CLINIC was the first to introduce blade-less LASIK( FEMTOSECOND) in Chennai.

UMA EYE CLINIC went a step further by bringing a FLAPLESS LASER. By introducing the Carl Zeiss VISUMAX SMILE to Chennai, thus pioneering the first FLAPLESS FEMTOLASIK into this part of the world. There will however there will be a certain patients who will not be fit to undergo LASIK. This could be due to very high power or thin corneas

Itrace

Such patients can be treated by a treatment modality known as INTRAOCULAR COLLAMER LENS Implant which UMA EYE CLINIC has been regularly doing from 2000. To learn more about how such patients can also have their refractive errors corrected, go to TOTAL REFRACTIVE SOLUTIONS.

Cataract

Uma eye clinic provides the state of the art management in the field of cataract surgery. We have embraced newer advances much ahead of our contemporaries. Being one of the pioneers of phacoemulsification in India enhancing patient comfort and quick visual rehabilitation has been the USP of UMA EYE CLINIC.

A state of the art diagnostic module including the IOL Master and iTrace, goes towards taking Cataract Surgery to a customized format. UMA EYE CLINIC offers CUSTOMIZED CATARACT SURGERY which gives the best quality of vision. Here the type of IOL is matched to the patient's optical system.

The IOL Master is currently the most accurate instrument in measurement and calculation of the most suitable IOL power for the patient. The iTrace is an advanced vision analysis system which can study the whole optical system of the eye.It includes the cornea, the crystalline lens and the internal structures. It helps to give PRECISE DIAGNOSTIC OUTCOMES which will help in planning the CUSTOMIZATION of the cataract surgery.

Uma Eye Clinic has also pioneered the use of Multifocal IOLs, Toric IOLs, Accomodative IOLs in the Asia Pacific Region. State of the art equipment Zeiss Lumera T microscope and Signature Whitestar Phacoemulsification System in our World Class Operation Theatre compliment the success of your cataract operation with us.

World Class Operation Theatres.+ve pressure, laminar airflow, 3 micron HEPA filter,DuPont Walls, anti-static flooring make the theatre conform to Organ Transplant Standards. And last but not the least, innovative and pioneering surgeons at UMA EYE CLINIC have been masters in the art and science of phacoemulsification for more than 25 years.

Glaucoma

Glaucoma has been aptly named the ' silent thief'.. Uma eye clinic has always been in the forefront of embracing new techniques and technology, be it in diagnosis or treatment. Glaucoma is a disease which causes irreversible damage to both the nerve and to sight. A transient rise in the Intraocular Pressure (IOP) leads to the damage of the optic nerve. So it is imperative to identify people who might develop the disease or catch the disease early in order to prevent further damage.

Uma eye clinic currently use very advanced diagnostic devices to detect, analyse and document glaucoma. The Spectral Domain OCT (Optical Coherence Tomography)analyses the ganglion cell layer to determine structural damage even before functional loss.

The ORA (Ocular Response Analyser) is used to take diagnosis and followability to a higher level. The Humphrey's Visual Field Analyser a gold standard in glaucoma diagnosis is used to compliment the findings of these highly sophisticated equipment. Uma Eye Clinic is one of the earliest to start using the SLT (Selective Laser Trabeculoplasty). Currently SLT is a painless LASER out patient procedure taking lesser than 5 minutes to perform. Patient can resume normal activities on leaving the clinic. This laser treatment helps to reduce the IOP thereby reducing the dependence on eye drops.

Our clinic currently has the largest series of Ologen implants in glaucoma surgery. Ologen is a biodegradable scaffolding which greatly enhances the success and safety of a glaucoma surgery.

World Class Operation Theatres.+ve pressure, laminar airflow, 3 micron HEPA filter,DuPont Walls, anti-static flooring make the theatre conform to Organ Transplant Standards.

Corneal Grafting

Cornea is the outer layer of the eye which helps focus and transmit light through the lens onto the retina. When the cornea is damaged beyond repair transplanting a donated cornea becomes a necessity. The cornea harvested after the donor?s death is screened for infectious diseases before grating.

Causes for damage

  • Congenital abnormalities
  • Childhood infections like measles
  • Severe trauma
  • Degenerative diseases due to exposure to harsh light

Types of corneal grafts

Partial thickness or Lamella grafts are used to treat conditions of the cornea where the damage is mostly restricted to the front surface of the cornea and only the front part of the cornea is replaced.

Full thickness or penetrating grafts are more commonly used and result in the whole of the cornea being replaced.

The procedure

The surgery is performed after the mandatory urine, blood and in some cases ECG rule out any complication. In the hour long operation the central piece of the cornea is cut and removed. This is replaced by the donor cornea which has been treated with an antibiotic solution.

The fine stitches will stay in place for up to 2 years and it will take at least a year to heal completely. The eye is covered with an eye pad and protective plastic eye shield post surgery. This is removed a day after the surgery and normal activities can be resumed as soon as possible. The patient returns home in a few days.

Post operation

  • Eyesight is blurred immediately after surgery
  • Eye may water and be sensitive to light
  • Sight will fluctuate due to the healing process
  • Cornea shape may change and necessitate glasses after a few months
  • There is absolutely no change in the physical appearance of the eye

Do's and Don'ts after the operation

  • Do not rub or touch the eye
  • Apply prescribed medication strictly according to schedule
  • Avoid smoky and dusty rooms, which can cause irritation.
  • Wear sunglasses if the eye is light sensitive
  • Do not play contact sports and swimming in particular. Ask the doctor if you are unclear which sports you should avoid
  • You will need at least 2-4 weeks off work, but again this will be discussed with you on an individual basis.
  • Avoid driving until the doctor tells you otherwise
  • Stick to your follow up appointments to check for other problems lind cataract retinal detachment
  • Return to the hospital immediately if you have
    • Increased pain
    • Increased redness
    • Increased watering or discharge
    • Further reduction in the vision

Diabetic Retinopathy

Diabetes and Eye

India is tipped to be the diabetes capital of the world by 2020. Diabetes mellitus affects various organs in the body including the eye. The changes in the eye due to diabetes are called diabetic retinopathy. Uma Eye Clinic has been providing Diabetic Eye Care Services for more than two decades. The Clinic has got a dedicated Vitreoretinal Surgeon who has been trained in world class institutes to handle patients with Diabetic Eye Diseases.

How does diabetes affect vision?

In diabetes mellitus, if the sugar level is not maintained under control with treatment, the blood vessels in the retina become structurally weak and leaky. This results in fluid accumulation in the retina or bleeding inside the eye. In advanced stages, there can be retinal detachment too. However, there are no symptoms in the early stage of the disease. The patient may notice slight reduction in vision or distortion of images. Many a time changes in the retina are diagnosed on routine examination. If left undetected, diabetic retinopathy can cause severe retinal damage and irreversible loss of vision.

How is diabetic retinopathy treated?

All diabetics should have periodical eye check up to find out if diabetic retinopathy has developed. Detection and grading is done on dilated retinal examination. Uma Eye Clinic offers comprehensive facilities to diagnose and treat diabetic retinopathy. The facilities to diagnose diabetic retinopathy available at Uma Eye Clinic are

  • Slit Lamp Biomicroscopy.
  • Indirect Ophthalmoscopy.
  • Fundus photography
  • Fundus Flourescein Angiography
  • Optical Coherence Tomography

Diabetic retinopathy can be treated with laser, intra vitreal injections or surgery. Uma Eye Clinic is equipped with state of the art Argon Laser Photocoagulation machine, Accurus Vitrectomy machine for retinal surgeries. Uma Eye Clinic offers suture less Vitrectomy surgeries for vitreous hemorrhage / retinal detachment due to diabetes retinopathy

If I am a diabetic what should I do to protect my eyes from diabetic retinopathy?

  • Keep your sugar under good control
  • Have periodical eye check up (at least once in a year) – Remember the involvement of eye is related to both the severity and duration of diabetes mellitus. So, longer you have diabetes, your eyes may get affected even if your sugar is under control.
  • Follow the doctor's advise regarding the various modes of treatment and follow up

Retina and Vitrous Disorders

Retina is the light receptive screen of the eye (akin to the screen in the camera) that sends visual messages to the brain through the optic nerve. When the retina is lifted or pulled from it normal position it gets detached. This interferes with the reception of light by the retina. If this is not treated immediately, this could result in permanent blindness. Retinal detachments are caused by a host of conditions in the eye,

  • Rhegmatogenous detachment – caused by retinal tears or breaks (dehiscence in the retina)
  • Tractional detachment – caused by tractional bands (due to fibrous tissue growth on the surface of retina)
  • Exudative detachment – caused by injury to or inflammation in the eye (when the retina is lifted by fluid accumulation behind it)

Of these Rhegmatogenous detachment is the most common type.

The vitreous is a gel like substance filling the eye behind the lens and in front of the retina. It is an optically clear viscous medium. The vitreous can be become opaque due to bleeding in the eye due to injury/ diabetes mellitus etc.

Retinal detachment can occur if you

  • Are over 40 years of age
  • Are myopic (especially high myopia)
  • Had a retinal detachment in one eye
  • Have a family history of retinal detachment
  • Have other eye diseases like retinoschisis, uveitis, lattice degeneration, retinal breaks etc
  • Had an eye injury
  • Untreated vitreous hemorrhage, diabetic retinopathy etc.

Symptoms of retinal detachment/ vitreous diseases you should look out for

  • Sudden appearance or increase in "Floaters" – black cobweb like little specks in the field of vision
  • Flashes of light
  • Appearance of a curtain over the field of vision
  • Sudden or gradual drop in vision

Treatment for retinal detachment / vitreous diseases

Uma Eye Clinic is fully equipped for the management of disorders of retina and vitreous with very experienced vitreo – retinal surgeon providing all the available treatment options. Uma Eye Clinic also has a – state – of – art machines and Operation Theater exclusively dedicated to treating vitreo – retinal conditions.

Diagnosis of retina and vitreous diseases is done with

  • Indirect Ophthalmoscopy
  • B – Scan ultrasound
  • Optical Coherence Tomography

Treatment of retina and vitreous diseases is done with

  • Laser indirect ophthalmoscopy – for retina breaks in which the hole or break in the retina is sealed with laser
  • Cryopexy – which freezes the area around the hole to reattach the retina
  • Pnuemoretinopexy – where air is injected into the vitreous to push the retina to its normal position
  • Scleral buckling – where a buckle is attached to outside of the eye to gently push the wall of the eye against the detached retina
  • Vitrectomy – is performed with the state of the art Accurus machine in which the vitreous is removed partly or totally through a small incision in the sclera, gas is injected into the eye to push the retina to its normal position

Over 90% of retinal detachment can be successfully treated with good visual outcome achieved when the patient presents early in the course of disease. It is vital to report to the eye specialist at the first instance of noticing floaters, flashes or curtain in the field of vision.

Squint and Oculomotor Disorders

Ocular motility is tested when patients complain of double vision or if neurologic disease is suspected. A visual assessment of the eyes tests for deviations that resulting from strabismus, extraocular muscle dysfunction, or palsy of the cranial nerves innervating the extraocular muscles. Saccadic dysfunction results in poor ability of the eyes to 'jump' from place to place. This will inhibit reading and other skills. This is tested by making the patient move his/ her eye quickly to targets at the far right, left, top and bottom.

The 'follow my finger' test makes the patient follow the examiner's finger as it traces an imaginary 'double H' which touches upon the eight fields of gaze. Inferior, superior, lateral and medial rectus muscles and the superior and inferior oblique muscles are tested.

Squint (Strabismus)

The eyes in a newborn are generally not aligned. Alignment is established only between 3-4 weeks. If misalignment persists in a baby over month old then it should be evaluated.

This condition where the eyes are misaligned and the two eyes look out in different directions is called Squint or Strabismus. This can either be permanent or occasional with eyes straight at other times. It is common in children and may also occur in adults.

It is caused by a lack of coordination between the six muscles that control the movement of each eye leading to misalignment. This may be the same in all directions or may be pronounced in one direction. This may be caused by refractive error, long sight or poor vision in one eye due to various eye diseases.

In case of squint a thorough examination of the eyes is necessary especially in children. An ophthalmologist will establish the nature and cause of squint after evaluation and suggest corrective measures.

The treatment will revolve around

  • Preservation or restoration of vision
  • Straightening of the eyes
  • Restoration of binocular vision

If there is a refractive error then that is treated first. If the squint is an Accommodative Squint this would be all that is required for correction. The eyes are checked for ambylopia and treated. The parents are involved in this procedure as their cooperation is vital for the success of the treatment. The squint is then treated surgically by strengthening or weakening the relevant muscles to restore balance and coordination.

It is essential to correct squint at an early age to avoid amblyopia. If it is not corrected by 10 years squint leads to ambylopia resulting in severe eye strain, headaches and abnormal head posture. Squint will never correct by itself. The earlier the treatment the better the result.

Contact Lenses

These thin plastid discs correct, improve all types of defective vision. They are also used for bandaging the eye after surgery and for cosmetic purposes to change the colour of the eye. They come as Rigid and soft lenses with varying levels of oxygen permeability- the greater the permeability the better.

Types of contact lenses

Rigid Gas Permeable (RGP) : enses are semi-rigid lenses made usually from acrylate and fluorosilicon, a plastic which allow oxygen through to the eye. They are clinically the best as they allow maximum oxygen to reach the cornea being smaller in size. They are easy to care for, durable and give good clarity of vision. They can be prescribed for all types of vision correction, including high astigmatism, bifocals, post surgery (RK, PRK,& Lasic), therapeutic, and cosmetic for all age groups. In certain cases these lenses are also prescribed for myopia control.

Soft lenses : Soft lenses are made from water-absorbing plastics, which make them pliable and membrane-like for maximum comfort. They are ideal for sports as they cannot be easily dislodged from the eye.

New silicon based soft lenses allow maximum oxygen to the cornea, enabling overnight continuous wear safely for a month. With modern manufacturing techniques, soft lenses can be made to correct all types of refractive errors and many types of lifestyles. Soft lenses are available in toric (to correct astigmatism), bifocal, weekly disposable, monthly disposable, daily disposable, extended wear and cosmetic to cover corneal scars, as well as to change the colour of one's eyes for fashion.

Irrespective of the type all lenses accumulate deposits from the secretions of the eye and the environment. All soft lenses are contaminated within 24 hours, when not in the eye, due to the water contained in the material. This makes contact lens care of vital importance.

Contaminated lens can cause

  • Recurrent infections
  • Red eyes
  • Papillae (pimples) on the inner lining of the upper eye lids
  • Reduced vision
  • Contact lens care
  • Lens should be kept clean, disinfected and hydrated
  • Hypoallergenic solutions formulate for sensitive eyes
  • Clean daily by rubbing in the palm of the hand with a surfactant cleaner
  • Protein cleaning should be done once a week

Frequent Replacement Lens

Build up of contaminants over a period of time, from three months onwards, is inevitable. A new system called Frequent Replacement has been introduced. Lenses are replaced on a Daily, Weekly, Monthly or Quarterly (once in three months) basis. Frequent infections are eliminated and the eye gets more oxygen. Vision and comfort are greatly enhanced and simple cleaning systems like multipurpose solutions can be used.

We offer the Holistic approach

At Uma Eye Clinic we lay great emphasis on proper guidance in the use of contact lens. We take the time to educate the patients on proper handling, cleaning and disinfection of their lenses.
