The Stellaris PC platform provides a high-performance, feature-rich, combined experience that leverages Bausch + Lomb's legacy of vitreoretinal surgical innovation with the demonstrated excellence of the Stellaris phacoemulsification platform. The Stellaris PC allows surgeons to have true "procedural choice" by providing the most advanced technology for both vitreoretinal and cataract surgery in a single system.It is a versatile system that allows surgeons the flexibility to perform different ophthalmic procedures while saving time, space and money for the surgeons and the patients they serve.

3. Carl Zeiss Lumera Operating Microscope

The Zeiss LUMERA from ZEISS is an operating microscope ideally suited for every ophthalmic surgery discipline. Experience markerless IOL alignment and integrated intraoperative OCT imaging - all in one device - from the ophthalmic microscope market leader. ZEISS LUMERA - our commitment to helping you save vision.

4.Carl Zeiss IOL Master V5 A-Scan

The Zeiss IOLMaster was approved by the United States Food and Drug Administration in March of 2000. A non-contact optical device that measures the distance from the corneal vertex to the retinal pigment epithelium by partial coherence interferometry, the IOL Master is consistently accurate to within +0.02 mm or better. The IOL Master is the first such device to be widely used in clinical ophthalmology. Calibrated against the ultra-high resolution 40-MHz Grieshaber Biometric System, an internal algorithm approximates the distance to the vitreoretinal interface, for the equivalent of an immersion A-scan ultrasonic axial length

5.Corneal Topography

Corneal topography is most commonly used for the following purposes

  • 1. Refractive surgery: To screen candidates for normal corneal shape, patterns and ruling out suspicious or keratoconic patterns . Post operatively , topography can help to assess the dioptric change created at corneal level ( thus the effective change in the cornea) , ruling out decentred or incomplete ablation , post excimer ectasia or other changes.
  • 2. Keratoconus : Early screening of keratoconus suspects is one of the most useful roles of topography. Early keratoconus and suspects look normal on slit lamp examination ,and the central keratometry (3 mm) gives only a limited assessment. Therefore topography has become the gold standard in screening keratoconus suspects. In cases with established keratoconus, the role of topography is paramount for monitoring progression and doing a timely collagen cross linking , and in contact lens fitting.
  • 3. Post surgery astigmatism : Post cataract surgery and post keratoplasty corneal astigmatism can be studied with the topographer and selective suture removal or other interventions can be planned.
  • 4. Surgical planning in cases with astigmatism : Limbal relaxing incisions and other methods of topography guided incision placement are used by surgeons to reduce post operative astigmatism.
  • 5. Effect of corneal and ocular surface disorders: Disorders such as pterygium , limbal dermoid, localised corneal scars can cause a change in the corneal topography and thus the monitoring is very useful.
  • 6. Other uses : Contact lens fitting , incision placement and intrastromal ring placement in keratoconus , monitoring of ocular vs corneal wavefront.

6.Intralase Lasik

IntraLase is a new state of the art laser treatment that prepares the LASIK corneal flap by using a femtosecond laser. Normal LASIK treatments use a mechanical device called a microkeratome which uses a blade to produce the LASIK flap.

This "No Blade" procedure produces a flap that is much more precise in depth, is cleaner, more accurate and is thinner. This results in many benefits to the LASIK patient.

Although advancements are made in laser eye treatment every year the introduction of IntraLASIK bladeless LASIK is the biggest leap in technology since the introduction of standard LASIK in the UK in 1998. It is a bigger advancement than the introduction of wavefront guided technology. Optimax were the first UK company to make IntraLase available nationally.


Fundus fluorescein angiography is a common procedure that is performed to give your doctor more information about the condition of the back of your eye. A small amount of yellow fluorescein dye will be injected into a vein in your arm. The dye travels to your eye where it highlights the blood vessels.

8.Carl Zeiss Visuals Green Laser

Green Laser VISULAS 532s from Carl Zeiss, Germany is used to stop the bleeding inside the eye in the treatment of diabetic retinopathy, different retinal vascular diseases and age related macular degeneration.

9.Carl Zeiss Optical Coherence Tomography

Optical coherence tomography (OCT) is adiagnostic imaging technology that provides cross sectional images of biological tissues. In ophthalmology,

OCT can perform "optical biopsy"noninvasively, imaging the retinawith a resolution higher than any other imaging modality other than histology. Now, nearly two decades sinceits introduction, OCT has become indispensable for research, screening, diagnosing, and monitoring diseases of the macula and optic nerve head.

10. B Scan

B-Scan Ocular Ultrasound Devices / B Scan of the Eye. B-scan Ultrasonography, often called just B-scan or Brightness scan, offers two-dimensional cross-sectional view of the eye as well as the orbit. A B-scan is used on the outside of the closed eyelid to view the eye.

11.Yag Laser

Neodymium-doped Yttrium Aluminum Garnet (Nd: YAG) laser is a solid state laser in which Nd: YAG is used as a laser medium.

These lasers have many different applications in the medical and scientific field for processes such as Lasik surgery and laser spectroscopy.

Nd: YAG laser is a four-level laser system, which means that the four energy levels are involved in laser action. These lasers operate in both pulsed and continuous mode.

Nd: YAG laser generates laser light commonly in the near-infrared region of the spectrum at 1064 nanometers (nm). It also emits laser light at several different wavelengths including 1440 nm, 1320 nm, 1120 nm, and 940 nm. YAG laser consists of three important elements: an energy source, active medium, and optical resonator.

12.Humphrey field analyser

Humphrey field analyser (HFA), is a tool for measuring the human visual field, it is used by optometrists, orthoptists and ophthalmologists, particularly for detecting monocular visual field.

The results of the Analyser identify the type of vision defect. Therefore, it provides information regarding the location of any disease processes or lesion(s) throughout the visual pathway. This guides and contributes to the diagnosis of the condition affecting the patient's vision. These results are stored and used for monitoring the progression of vision loss and the patient's condition.

13.Non Contact Tonometer

A tonometer is a diagnostic tool used by eye care professionals to measure the intraocular pressure (IOP) inside a patient's eyes. A patient's IOP can help an ophthalmologist or optometrist determine a patient's risk for developing glaucoma - a disease that damages the optic nerve of the eye, usually resulting in vision loss or even blindness. A non-contact tonometer uses a small puff of air (which is why it's many times referred to as the "puff test") to measure an eye's pressure. Known as pneumotonometry, the air puff flattens the patient's cornea in a non-invasive way, meaning eyes do not need to be numbed prior to the test.

14.Applanation Tonometer

Consultant - General Ophthalmology

Applanation Tonometer is an instrument that is based on Imbert-Fick law. It is considered to be the gold standard instrument for measurement of Intraocular pressure (IOP).

Goldmann applanation tonometer is based on the Imbert-Fick principle, which states that for a dry thin-walled sphere, the pressure (P) inside the sphere equals the force (F) necessary to flatten its surface divided by the area (A) of flattening (i.e. P = F/A). It applies to surfaces which are perfectly spherical, dry, flexible, elastic and infinitely thin.Theoretically, average corneal rigidity (taken as 520 ?m for GAT) and the capillary attraction of the tear meniscus cancel each other out when the flattened area has the 3.06 mm diameter contact surface of the Goldmann prism, which is applied to the cornea using the Goldmann tonometer with a measurable amount of force from which the IOP is deduced.
