Our Specialist Ophthalmologists in Dubai Perform the Following
OPTICAL COHERENCE TOMOGRAPHY (OPTOVUE)
OCT is a cutting-edge technology used to perform high-resolution cross-sectional imaging of eye structures. It works similarly to ultrasound imaging, expect it uses light instead of sound. Thus, it produces resolution in micron scale in situ and in real time. OCT is useful in diagnosing retinal conditions and disorders affecting the optic nerves, cornea and eyesight.
HUMPHREY VISUAL FIELD Zeiss
It is the gold standard in perimetry for diagnosing, analyzing and managing glaucoma. Many neurological diseases can affect peripheral vision. We offer specialized tests to diagnose and treat these conditions.
GALILEI FOR CORNEAL MAP ZIMMER
This is a non-invasive imaging technology used to map the cornea’s surface curvature and the eye’s outer structure. Corneal topography enables the comprehensive diagnosis of keratoconus, as well as pre-operative evaluation and post-operative management for LASIK surgery. It is also useful for evaluating lens and AC angle.
IOL MASTER 700 Zeiss
Uses non-contact technique to perform highly accurate preoperative IOL calculations. It is very useful in patients who have previously undergone LASIK surgery.
FUNDUS FLUORESCEIN ANGIOGRAPHY
It registers the dynamic interaction of fluorescein with the ocular fundus in both its normal and abnormal anatomic structures. The test provides a thorough understanding of the circulation phases, which is essential for interpreting abnormalities. This can detect diabetic retinopathy, edema of the optic disc, retinal vein occlusions, retinal artery occlusions, and tumors.
This instrument can also be used for taking pictures of Ocular fundus.
A SCAN AND B SCAN Sonomed
Amplitude Scan, or A-scan, is an amplitude modulation scan. This technology measures Intra-Ocular Lens (IOL) power. Brightness Scan, or B-scan, is an essential adjuvant for the clinical assessment of various orbital and ocular diseases. It is also used to examine the posterior segment of hazy ocular media.
COMPUTER & PNEUMATIC TONOMETER, REFRACTOMETER
It is a non-contact method used for determining intraocular pressure (IOP). The test is important in evaluating patients who are at risk of developing glaucoma. Autorefractor Keratometer is utilized to evaluate refractive status and corneal keratometry readings.
WAVEFRONT ANALYZER AND CORNEAL TOPOGRAPHY ( ZEISS)
Customizes LASIK correction procedure. Corneal topography is a computer-assisted diagnostic tool for eye examination. It creates a 3D map of the surface curvature of the cornea.
ELECTRORETINOGRAPHY (ERG) AND ELECTROOCULOGRAM (EOG)
Electroretinogram (ERG) is a diagnostic examination that measures the electrical activity produced by neural and non neuronal cells in the retina in response to a stimulus (light). During the test, the eyes of the patient are exposed to standardized stimuli. After which, the resulting signal is displayed with information on the time course of the signal’s amplitude (voltage). ERG can provide important data on a broad spectrum of retinal disorders, including congenital stationary night blindness, Leber congenital amaurosis and cancer-associated retinopathy.
In addition, ERG can monitor the progression of a disease and test for retinal toxicity from various drugs or from a retained intraocular foreign body.
SPECULAR ENDOTHELIAL MICROSCOPY
A special instrument that enables our eye specialist in Dubai and the photographer to examine and document the corneal endothelial cells. It uses a bright specular or mirror-like image which is created when the angle of the light for photography is correct. Images produced by the procedure allow an ophthalmologist in Dubai to conduct a “cell count” of the corneal endothelium. Normal cell count ranges from 2000 to 3200 per millimeter squared.
Cell counts are performed to evaluate various procedures, primarily those used for / in cataract surgery. Eye and tissue banks regularly use the specular microscope to evaluate a donor cornea before a corneal transplant.
Corneal and Refractive Surgery
INTRA-LASIK AND EPI-LASIK
Corrects near-sightedness, far-sightedness and astigmatism. Our ophthalmologist in Dubai uses the most advanced LASIK technology to treat all refractive errors.
What is LASIK/Refractive Surgery?
Our eye specialist in Dubai performs LASIK surgery as an outpatient procedure in the comfort and convenience of our state-of-the-art laser surgical suite. The entire procedure can be completed in less than 1 minute. Both eyes are corrected in the same setting. The procedure includes use of topical anesthesia (eye drops). Patients can see a dramatic improvement in their vision within the first day, and most of them are able to return to their normal activities after 1-2 days.
The cornea is composed of a clear tissue layer covering the eye surface, similar to a watch crystal. A corneal transplant is recommended and performed to restore functional vision if the cornea has become cloudy or opaque due to a disease, scar, infection, swelling or chemical burn.
IMPLANTABLE COLLAMER LENS (ICL)
Visian ICL is a 15-minute procedure that allows patients to experience immediate improvement in the quality of their vision. The procedure uses Collamer, a technologically advanced lens material. It has a collagen base that makes it 100 percent compatible with the body’s natural chemistry.
Descemet’s Stripping Endothelial Keratoplasty ( DSEK)
It is a type of corneal transplant procedure where only the back layer of the cornea (endothelium) is transplanted. It is different from a penetrating full thickness keratoplasty wherein the whole cornea is transplanted.
DEEP ANTERIOR LAMELLAR KERATOPLASTY (DALK)
It is a
Surgical procedure done to remove the corneal stroma down to Descemet’s membrane. It is performed to treat a corneal disease where the endothelium is still functioning normally.
CORNEAL INLAY FOR PRESBYOPIA CORRECTION
It is the latest femtosecond assisted corneal inlay technique designed for presbyopia patients. Also called keratophakia, corneal inlays are implants placed in the corneal stroma to correct presbyopia, a condition that limits a person’s ability to accommodate or focus on near objects.
Young people can generally focus easily on near and distant objects. They are able to see near objects clearly because of the contraction of the ciliary muscle and the increase in curvature of the anterior surface of the lens, which is a process called accommodation. This ability starts to decrease after the age of 40, making it difficult to see near objects.
The usual solution to presbyopia is to wear reading glasses. However, presbyopic people who want an alternative option to wearing glasses can choose corneal inlays to correct their decreased near vision. Corneal inlays work by enhancing the depth of focus, or the refractive power of the cornea’s central or paracentral part. They do not, however, restore a person’s ability to accommodate, as the inlays have zero effect on the ciliary muscle or the lens. Corneal inlays can also correct hyperopia, myopia and astigmatism.
Cataract and Glaucoma Treatment
SUTURELESS CATARACT SURGERY (PHACO)
Phacoemulsification cataract surgery is a modern procedure that uses an ultrasonic device to break up and remove cataract from the eye to improve vision. Insertion of intraocular lens (IOL) usually follows the phacoemulsification immediately.
This technique removes the need for anesthetic injection behind the eye and the need for sutures. Benefit for patients also include safety, reduced surgery time, relief from stress and discomfort, minimized risk of complications and higher success rate.
This type of laser procedure cleans the membranes in the eye that have congealed after cataract surgery. It is also highly effective for treating certain forms of glaucoma, such as Peripheral Ividotomy.
MICROINVASIVE GLAUCOMA SURGERY (MIGS)
All glaucoma surgeries are performed with the aim of lowering eye pressure to avoid or lessen damage to the optic nerves. Standard glaucoma surgeries, such as trabeculectomy and Ex-Press shunts, are major surgical procedures. Although these are often very effective at decreasing eye pressure and preventing glaucoma from worsening, they have several potential complications. The MIGS group of operations have been developed in recent years to reduce some of the complications of most standard glaucoma surgeries.
GLAUCOMA TREATMENT (SURGERY OR LASER)
Glaucoma is a degeneration of the optic nerve of the eye which leads to progressive loss of peripheral vision. Measurement of IOP, angle study, corneal pachymetry, OCT optic nerve analysis and Visual field analysis (perimetry) are essential tools for managing glaucoma. Eye pressure is modulated with eye drops, laser or incisional surgery. There are 2 types of laser treatment depending on the type of glaucoma you have:
SLT (selective laser trabeculoplasty) and LPI (laser peripheral iridotomy). SLT is a relatively new laser that uses low energy light to enhance the natural mechanism of fluid drainage from the eye to help treat open-angle glaucoma. SLT and LPI treatments are painless.
LASER TRABECULOPLASTY FOR GLAUCOMA
Laser trabeculoplasty uses a highly concentrated and potent light beam to treat the drainage angle of the eye. This surgery makes it easier for fluid to flow out of the front part of the eye, decreasing pressure in the eye.
AHMED GLAUCOMA VALVES
These devices can successfully control intraocular pressure (IOP) in the eyes caused by a previous failed trabeculectomy and in eyes with inadequate conjunctiva due to scarring from prior injuries or surgery. The devices have also shown success in treating complicated types of glaucoma, including uveitic glaucoma, pediatric and developmental glaucoma, and neovascular glaucoma.
Treatment for Keratoconus
SPECIAL LENS FOR KERATOCONUS PATIENTS
Keratoconus is a non inflammatory eye condition where the normally round and dome shape of the cornea gradually thins and causes a cone-like bulge to form. This leads to significant visual impairment. Treatment for keratoconus depends on the severity of the disease. Wearing eyeglasses or soft contact lenses may correct mild nearsightedness and astigmatism caused by the disease’s early stages. As the disorder progresses, rigid gas permeable contact lenses are the usual method of correction prescribed.
Soft contacts designed for keratoconus are typically thicker at the center than standard soft lenses, ranging from 0.3 mm to 0.6 mm. The increased central thickness helps prevent the contacts from conforming to the cornea’s irregular shape. Soft lenses make it possible to mask mild to moderate irregular astigmatism.
It is a treatment that aims to stop the progression of keratoconus, and thus prevent vision from further deteriorating and requiring corneal transplant. It is a non-invasive outpatient procedure. Clinical studies have shown the treatment is successful in increasing the amount of collagen cross linking in the cornea and in strengthening the cornea. During the process, custom-made riboflavin drops saturate the cornea; these drops are then activated by an ultraviolet light.
INTRACORNEAL RING WITH INTRALASE
Intacs are made of thin semi-circular plastic rings. These are placed into the middle layer of the cornea. The procedure is used primarily to treat keratoconus. It is considered more precise and less traumatic than using mechanical keratome.
The thinning of the cornea often results in protrusion, perforation and irregular astigmatism. Eye disorders such as keratoconus, Pellucid Marginal Degeneration (PMD), and Keratoglobus do not have known causes, whereas corneal ectasia can be acquired following a LASIK procedure.
Corneal ectatic disorders may impair vision, but it can be restored using glasses or soft or rigid gas permeable contact lenses. However, severe disorders may need correction or restoration of tectonic integrity of the cornea through surgery.
Intrastromal corneal ring segments, or ICRS, are made of polymethylmethacrylate (PMMA). These are inserted into the deep corneal stroma to correct the corneal curvature. ICR is a device designed to modify mild to moderate cases of myopia through flattening the anterior corneal curvature without encroaching the visual axis.
Eye Deviation Surgery (Squint)
EYE DEVIATION SURGERY (SQUINT)
Strabismus is the medical term for a condition where a person’s eyes do not align properly when looking at an object. Commonly called “crossed eyes,” people with this condition have one of their eyes turning in, out, up or down. In some cases, an eye may be constant (turning all of the time), or intermittent (turning only some of the time).
Strabismus in children does not go away on its own, but it is treatable in adults. Strabismus patients can be treated by eye glasses, orthoptic exercises, amblyopia treatment, or even surgery in selected cases.
PLASTIC LID SURGERY (BLEPHAROPLASTY)
Upper and Lower Eyelid Fat Removal without cutting the skin. Blepharoplasty is the plastic surgery operation for correcting defects, deformities, and disfigurations of the eyelids; and for aesthetically modifying the eye region of the face.
Ptosis is a drooping of the upper or lower eyelid. Ptosis surgery is usually done under local anesthesia as a day case.
EYELID COSMETIC SURGERY
Aesthetic eyelid surgery has the effect of making you look more rested, refreshed and alert.
Movable Artificial Eye (Hydroxyapatite)
Artificial eye is a type of craniofacial prosthesis that replaces an absent natural eye. Hydorxyapatite promotes fibrovascular ingrowth and seemingly true integration of the motility implant to the residual ocular structures.
Retinal Disease Treatment
LASER TREATMENT FOR RETINAL DISEASES
The retina is the inner layer of the eye that senses light and helps you to see. Laser has been one of the great advances in treating retinal diseases like retinal holes, tears, diabetic retinopathy and macular degeneration.
Argon laser treatment is used to treat a range of eye conditions including glaucoma, diabetic eye disease and some retinal holes and tears. It can prevent an eye condition from getting worse, or sometimes cure it. The laser machine is attached to a slit-lamp microscope, similar to one used when your eyes are being examined in the clinic.
INTRAVITREAL LUCENTIS INJETION
It is an advanced treatment option for Diabetic Macular Edema (DMA) and neovascularization caused by wet ARMD and retinal vein occlusion. Instead of retinal laser and complicated surgery, a very small amount of medicine is injected into the eye.
Lucentis, which is also recognized as ranibizumab injection, is a medicine originally used to treat the wet form of age-related macular degeneration (referred to as AMD or ARMD in 2006). AMD primarily affects the macula, which is part of the eye responsible for producing sharp central vision.
Lucentis can treat swelling within the macula (macular edema) that is caused by vein occlusion or diabetes. It can also impede the development of vascular endothelial growth factor (VEGF), a type of protein that causes abnormal blood vessels to expand and leak, eventually damaging the macula. Through delaying or hindering VEGF development, Lucentis is able to help prevent or reverse vision loss experienced by individuals who have macular edema. The treatment has been specifically designed to be used in the eyes.
This surgery is used to treat various disorders related to the retina, vitreous and macula. Ophthalmic surgeons use specialized techniques, equipment and solutions to treat conditions such as retinal detachment, macular degeneration, diabetic retinopathy and uveitis. Retinal and vitreous problems can cause severe loss of vision or even blindness.
Vitrectomy is a type of surgery performed to remove some or all of the vitreous humor (a clear gel that fills the space between the lens and the retina of the eyeball) from the eye.
Retinal Detachment Surgery
Methods of repairing a retinal detachment include:
- Pneumatic Retinopexy – In this procedure, your eye specialist in Dubai injects a gas bubble into the middle of the eye ball. The gas bubble then floats into the detached area and lightly pushes against the detached retina. The movement flattens the detached retina and the fluid below it is reabsorbed. Your ophthalmologist will then use a freezing probe (cryopexy) or a laser beam (photocoagulation) to seal the tear in the retina.
- Scleral Buckling Surgery – Your ophthalmologist in Dubai will place a piece of silicone sponge, rubber or a semi-hard plastic onto the outer layer of your eye, which will then be sewn into place. This will help relieve pulling (traction) on the retina to prevent tears from worsening. It will also provide support to the layers of the retina.
Transnasal D.C.R (Dacryocystorhinostomy)
A surgical procedure done to restore the flow of tears into the nose from the lacrimal sac when the nasolacrimal duct does not function. It is performed through the nose hence there are no scars.
Pediatric ophthalmology is a sub-specialty of ophthalmology dedicated to vision care for children, including treatment of eye diseases and visual development. Children are also susceptible to a variety of eye problems, many of which are quite distinct from eye diseases among adults. We have a team of ophthalmologists at our Dubai clinic who are specially trained to manage the following eye disorders in children: Infection (Conjunctivitis), strabismus, blocked tear ducts, refractive errors (such as myopia and astigmatism), ptosis and amblyopia (lazy eye).
LOW VISION AIDS FOR THE VISUALLY IMPAIRED
Low Vision Aids are tools that help those with vision loss to maximize their remaining vision It is clinically proven to improve reading speed:
Video magnifiers are sometimes called “closed-circuit television (CCTV) systems” and generally use stand-mounted or hand-held video cameras to project a magnified image onto a video monitor, a television screen, or a computer monitor. Desktop video magnifiers generally have a table surface on which the object is placed. Directly above the object, is a camera and monitor upon which the magnified image is projected. Some desktop systems allow the user to project the image onto a standard TV instead of an integrated monitor.
Neuro ophthalmologists manage visual problems related to the nervous system – these visual problems do not come from the eyes themselves. Neuro-ophthalmology is a subspecialty of the fields of neurology and ophthalmology. It requires specialized training to acquire the expertise needed to manage problems of the eye, brain, nerves and muscles.
Some eye problems diagnosed by a neuro ophthalmologist may be insignificant, but other conditions may worsen and cause permanent loss of vision, or in some cases, may even become life threatening. Sometimes, the problem only affects the optic nerve or the nervous system, and other times it is related to a general medical condition. Neuro ophthalmologists have unique abilities to evaluate patients from the neurologic, ophthalmologic, and medical standpoints to diagnose and treat a wide variety of problems. Costly medical testing is often avoided by seeing a neuro ophthalmologist.
