Centurion® Vision System

This is one of the most intelligent phaco-emulsification technologies that helps in optimizing Cataract Surgery. One of the widely used surgical procedure for Cataracts is the phacoemulsification which entails making a small incision in the eye followed by a tiny probe where ultrasonic phaco (USP) energy is used to help fragment and remove the cataract from the eye. The Centurion® Vision System is designed to optimize cataract procedures by providing eye surgeons control and better efficiency. The system automatically and continuously adapts to changing eye conditions providing more consistent IOP and greater anterior chamber stability during each step of the surgery.

The team at TESS has been using the Centurion® Vision System for cataract procedures thus providing their patients access to latest surgical methods for better outcomes.

Fundus Fluorescein(FFA) and Indocyanine Green ( ICG) Angiography

Fundus Fluorscein Angiography (FFA) and Indocyanine Green (ICG) Angiography are useful diagnostic tools for the diagnosis and monitoring of retinal vascular and macular diseases.

FFA and ICG angiography are simple diagnostic tests, which involve the injection of fluorescein (yellow) dye and/or indocyanine green into your bloodstream followed by a series of photographs taken over several minutes. The FFA test helps the doctor get more information about the condition of a patient’s retina. The ICG test provides information about the choroid which lies underneath the retina. Based on the results of the tests the ophthalmologists are able to decide the best treatment options.

Used for visual field testing in glaucoma and various neurological and neuro-ophthalmological disorders

Intraocular lens power measurement (ASCAN-Biometry)

A-scan Ultrasound biometry, also referred to as jA-scan, utilizes an ultrasound device for diagnostic testing in Ophthalmology. It is used to determine the length of the eye and can be useful in diagnosing common sight Disorderss. For cataract patients, A-scans are extremely beneficial since they help the ophthalmologist determine the power of the intraocular lens (IOL) needed for the artificial implant.

Laser for diabetes & retinal problems (Green Laser)

Lasers to seal up leaky blood vessels

  • Focal laser for diabetic macular edema
  • Laser for macroaneurysm
  • Laser for wet macular degeneration (rarely done today)

Lasers to destroy damaged retina to protect healthy retina

  • Pan retinal photocoagulation for proliferative diabetic retinopathy or sickle retinopathy

Laser to create an adhesion when the retina is torn or detached

  • Laser for retinal tear
  • Laser for retinal detachment
Laser for after cataract (Nd:YAG Laser)

Nd YAG (Neodymium-yttrium-aluminum-garnet) laser are used in ophthalmology to remove posterior capsular opacification, a condition that may occur after cataract surgery,  to do surgery. It is also used to punch a hole in the iris to relieve increased pressure within the eye from acute angle-closure glaucoma.

Synoptophore – for lazy eye and squint

 It is an instrument which compensates for the angle of squint and allows the stimuli to be presented to both eyes simultaneously. It is an ophthalmic instrument which is used for diagnosing the imbalance of the eye muscle and treating them by orthoptic methods

Contact lens fitting- routine and advanced

Eye examination in case of contact lenses is different from routine eye exams for glasses as there are special tests and measurements that need to be conducted in order to ensure proper fitting and prescription update. Typically, visual acuity is tested with an eye chart and eye health is assessed to determine if prescription eye wear is needed to correct refractive errors. The doctor may want to understand your lifestyle and preferences regarding contact lenses such as whether you want to change your eye colour with contact lenses or are interested in daily disposables or overnight lenses or whether you would like rigid gas permeable (RGP or GP) contact lenses since they provide provide sharper vision than soft lenses.

Specialized contact lens - Boston scleral lens - For Blinding Corneal Diseases

In some patients, contact lenses cannot be prescribed due to irregular cornea or other problems, in which case, scleral lens can be a consideration. These are large diameter gas permeable contact lenses designed to vault over the entire corneal surface and rest on the “white” of the eye. Scleral lenses functionally replace the irregular cornea with a perfectly smooth optical surface to correct vision problems caused by keratoconus and other corneal irregularities. Additionally, the space between the cornea and the back surface of a scleral lens acts as a fluid reservoir thus providing comfort to patients with dry eyes who were not candidates for contact lens wear

Low vison aid for visually handicapped

Low vision devices can help patients with low vision perform everyday tasks more easily.

There are several different categories of low vision devices: optical devices, non-optical devices, and electronic magnifiers and magnifying systems. Low vision devices are task-specific, designed for close-up visual tasks or distance viewing. In some patients depending on the eye condition and everyday needs, different devices may be required.

Examples of Low vision optical devices include a variety of helpful visual aids, stand and hand-held magnifiers, strong magnifying reading glasses, loupes, and small telescopes. These devices are powerful as they provide greatly increased magnification powers and prescription strengths, along with higher-quality optics. They are different from regular glasses and magnifiers and at times require training to help patients use them effectively.

Low vision non-optical devices include adaptations such as reading stands, supplemental lighting, glare control sunglasses etc. They can be used in combination with low vision optical devices and can help with a variety of everyday tasks.

Scanning of the eye-(OCT)

OCT is to obtain high-resolution cross sectional images of the retina and anterior segment. It is used to diagnose and monitor treatment of retinal diseases, Corneal ailments and in early detection of glaucoma

Test for corneal shape and thickness-( Pentacam-Oculyzer)

The Pentacam Oculyzer is used to monitor the cornea and generate reliable results in no time. A very sophisticated test used for portraying the cornea as the doctor gets a detailed depiction of the anterior and posterior surface of the cornea, as well as high-resolution densimetric maps.

It is one of the machines that help the ophthalmologist decide whether a patient is a good candidate for correction of myopia, astigmatism and hyperopia as well as which laser method is in the best interest for the patient.

It is very sensitive in the detection of keratoconus and its follow up.

Laser removal of glass Numbers (LASIK)

LASIK, an acronym for laser-assisted in situ keratomileusis, is the most commonly performed laser eye surgery to treat myopia, hyperopia and astigmatism.

This LASIK procedure reshapes the cornea to enable light entering the eye to be properly focused onto the retina for clearer vision. LASIK surgery is essentially pain-free and takes only about 15 minutes for both eyes. The results — improved vision without eyeglasses or contact lenses — begin immediately after the procedure and vision usually continues to improve and stabilize over a few days.

If a patient is not fit for LASIK, there are other vision correction surgeries including PRK and LASEK laser eye surgery and phakic IOL surgery.

An automated instrument called a corneal topographer is used to measure the curvature of the front surface of the eye and create a "map" of your cornea. With wavefront technology a patient is likely to undergo wavefront analysis that sends light waves through the eye to provide an even more precise map of aberrations affecting your vision.

Patients wearing contact lenses are advised to not wear them for approximately 2 weeks prior to surgery. This is because contact lens wear can temporarily alter the natural shape of your cornea.

Wavelight EX 500 laser for LASIK surgery

They are most commonly used to correct myopia (nearsightedness) but can also be used to correct hyperopia (farsightedness) and astigmatism. The excimer laser alters the refractive state of the eye by removing tissue from the anterior cornea through a process known as photoablative decomposition.

Carl Zeiss Slit lamp SL 120

The slit lamp in conjunction with a biomicroscope is indispensable for the detailed examination of virtually all tissues of the eye and some of its adnexa. It is routinely used for examination of the anterior segment, which includes the anterior vitreous and those structures that are anterior to it

Optical Biometer- LENSTAR

The LS 900 is a non-invasive, non-contact OLCR (optical low-coherence reflectometry) biometer used for obtaining ocular measurements and performing calculations to assist in the determination of the appropriate power and type of IOL (intraocular lens) for implantation after removal of the natural crystalline lens.
