LASIK MACHINE

ZEISS MEL 90

LASIK is a surgical procedure that uses a laser to correct nearsightedness, farsightedness, and/or astigmatism. In LASIK, a thin flap in the cornea is created using either a microkeratome blade or a femtosecond laser. The surgeon folds back the flap, then removes some corneal tissue underneath using an excimer laser. The flap is then laid back in place, covering the area where the corneal tissue was removed.With nearsighted people, the goal of LASIK is to flatten the too-steep cornea; with farsighted people, a steeper cornea is desired. LASIK can also correct astigmatism by smoothing an irregular cornea into a more normal shape.

OCT Machine

ZEISS CIRRUS HD-OCT 500

Optical coherence tomography (OCT) is an established technique that uses light to capture micrometer-resolution, three-dimensional images from within optical scattering media (e.g., biological tissue). Optical coherence tomography is based on low-coherence interferometry, typically employing near-infrared light. The use of relatively long wavelength light allows it to penetrate into the scattering medium.

 

Green Laser Unit

ZEISS VISULAS 500

Retinal Photocoagulation Lasers are used to treat a variety of eye diseases including the two leading causes of blindness : 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 - the first is Focal Photocoagulation, which treats specific leaking blood vessels in the retina. The second is Scatter or Pan-retinal Photocoagulation; - used for more widespread damage over the retina. The risk of using a Retinal Photocoagulation Laser are low and side affects are rarely severe.

Vitreo Retinal Surgery

ALCON CONSTELLATION TT

Vitreoretinal surgery refers to any operation to treat eye problems involving the retina, macula, and vitreous fluid. These include retinal detachment, macular hole, epiretinal membrane and complications related to diabetic retinopathy.

Kerato Analyzer

KONAN KERATO ANALYZER

A kerato Analyzer, also known as  an ophthalmoanalyzer, is a diagnostic instrument for measuring the curvature of  the anterior surface of the cornea, particularly for assessing the extent and  axis of astigmatism. It was invented by the German physiologist Hermann von  Helmholtz in 1880, (although an earlier model was developed in 1796 by Jesse  Ramsden and Everard Home.

Pachymetery

TOMEY TMS 4

A pachymeter is a medical device used to measure the thickness of the eye's cornea. It is used to perform corneal pachymetry prior to refractive surgery, for Keratoconus screening, LRI surgery and is useful in screening for patients suspected of developing glaucoma among other uses.

Ophthalmoscopy

Ophthalmoscopy (funduscopy) is a test that allows a health professional to see inside the fundus of the eye and other structures using an ophthalmoscope (or funduscope).

It is done as part of an eye examination and may be done as part of a routine physical examination.

It is crucial in determining the health of the retina, optic disc, and vitreous humor.

Auto Refractometers

NIDEK AUTOREFRACTOR 610

A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry).  Automatic refractometers automatically measure the refractive index of a sample.

Phaco system

ALCON CENTURION PHACO MACHINE

Phacoemulsification is a modern cataract surgery in which the eye's internal lens is emulsified with an ultrasonic handpiece and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution, thus maintaining the anterior chamber, as well as cooling the handpiece.

Fundus Camera

TOPCON TRC 50DX

Fundus photography involves capturing a photograph of the back of the eye i.e. fundus. Specialized fundus cameras that consist of an intricate microscope attached to a flashed enabled camera are used in fundus photography. The main structures that can be visualized on a fundus photo are the central and peripheral retina, optic disc and macula. Fundus photography can be performed with colored filters, or with specialized dyes including fluorescein and indocyanine green.

Microscope

ZEISS VISU 210

Microsurgery is a general term for surgery requiring an operating microscope. Microsurgical techniques are utilized by several specialties today, such as: general surgery, ophthalmology, orthopedic surgery, gynecological surgery, otolaryngology, neurosurgery, oral and maxillofacial surgery, plastic surgery, podiatric surgery and pediatric surgery.

Tonometers

KEELER TONOMETER

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. Most tonometers are calibrated to measure pressure in millimeters of mercury (mmHg).

Slit lamps

ZEISS SLIT LAMPS

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.

Yag Laser

 

ZEISS VISULAS YAG LASER

Nd:YAG (neodymium-doped yttrium aluminium garnet; Nd:Y3Al5O12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant, triply ionized neodymium, Nd(III), typically replaces a small fraction (1%) of the yttrium ions in the host crystal structure of the yttrium aluminium garnet (YAG), since the two ions are of similar size. It is the neodymium ion which provides the lasing activity in the crystal, in the same fashion as red chromium ion in ruby lasers.

A B-Scan

ALCON  A B SCAN

Ultrasound is a quick and painless procedure.  It is performed in your doctor’s office. For an A-Scan, your doctor will numb your eye with eye drops.  A small transducer device is placed on your eye.  The transducer transmits sound waves to a computer that produces images of the structures inside your eye.  A B-scan is done through the closed eyelids and requires no preparation..

Humphrey Field Analyser

ZEISS HUMPHREY FIELD ANALYZER

The Humphrey Visual Field Analyser (HVFA), is a tool for measuring the human visual field, it is used by optometrists, orthoptists and ophthalmologists, particularly for detecting monocular visual field.
