List of Eye Test

Here is the list of all Eye Tests done by Dr. Himanshu Mehta Best Ophthalmologist in Mumbai. Please don't forget to vote for your faves!"



The VERION Reference Unit enables surgeons to quickly determine an optimized surgical plan for toric or multifocal procedures with

  • Customizable incision and implantation axis planning
  • Built-in IOL calculation formulas, including lens and power selection
  • Intuitive astigmatism management software

The[ VERION]™ Image Guided System Can help:

  • Minimize data transcription errors
  • Improve clinical efficiency
  • Increase toric and multifocal IOL confidence
  • Ensure surgical consistency
  • Optimize visual outcomes

Fundus photography involves photographing the rear of an eye; also known as the fundus. Specialized fundus cameras consisting of an intricate microscope attached to a flash enabled camera are used in fundus photography.


  • Quick and simple technique to master
  • Observes a larger retinal field at any one time compared with ophthalmoscopy
  • Dilation not required, making it a less invasive procedure than traditional methods
  • High patient compliance
  • Images can be saved and used at a later time or by different clinicians
  • Progression of diseases can be monitored over time, allowing for better management plans
  • Different filters and dyes available to allow for different types tests
Perimetry (Visual Field Test)

Perimetry is the systematic measurement of the visual field function. The two most commonly used types of perimetry are Goldmann kinetic perimetry and threshold static automated perimetry.
A perimetry test can help find certain patterns of vision loss. This may mean a certain type of eye disease is present. It is very useful in finding early changes in vision caused by nerve damage from glaucoma.
Regular perimetry tests can be used to see if treatment for glaucoma is preventing further vision loss.

Color Vision Test

Color vision is the ability of an organism or machine to distinguish objects based on the wavelengths (or frequencies) of the light they reflect, emit, or transmit. Colors can be measured and quantified in various ways; indeed, a person's perception of colors is a subjective process whereby the brain responds to the stimuli that are produced when incoming light reacts with the several types of cone cells in the eye. In essence, different people see the same illuminated object or light source in different ways.


There is no cure for inherited color deficiency. But if the cause is an illness or eye injury, treating these conditions may improve color vision.

Using special tinted eye glasses or wearing a red-tinted contact lens on one eye can increase some people's ability to differentiate between colors, though nothing can make them truly see the deficient color.

Most people with color vision deficiency find ways to work around the inability to see certain colors by:

Organizing and labeling clothing, furniture or other colored objects (with the help of friends or family) for ease of recognition.
Remembering the order of things rather than their color. For example a traffic light has red on top, yellow in the middle and green on the bottom.

Corneal Topography

Corneal topography is a computer assisted diagnostic tool that creates a three-dimensional map of the surface curvature of the cornea. The cornea (the front window of the eye) is responsible for about 70 percent of the eye’s focusing power. An eye with normal vision has an evenly rounded cornea, but if the cornea is too flat, too steep, or unevenly curved, less than perfect vision results. The greatest advantage of corneal topography is its ability to detect irregular conditions invisible to most conventional testing.

Optical Coherence Tomography (OCT)

Optical coherence tomography (OCT) is a non-invasive imaging test. OCT uses light waves to take croWith OCT, your ophthalmologist can see each of the retina’s distinctive layers. This allows your ophthalmologist to map and measure their thickness. These measurements help with diagnosis. They also provide treatment guidance for glaucoma and diseases of the retina. These retinal diseases include age-related macular degeneration (AMD) and diabetic eye pictures of your retina.
