Best Optometrist in Houston | Top Technologies used by Pupila Eye Care



Pupila Eyecare uses one of the latest secure electronic health record systems to maximize efficiency of care delivered. Our secure EHR ensures that your health information is available whenever and wherever it is needed.


“Which is better Option 1 or 2? 3 or 4?” This can be stressful and confusing to many patients. But at Pupila Eyecare, Dr. Krishnan uses the latest refraction technology to digitally refract her patients. An automated phoropter provides greater accuracy for your prescription.  With the touch of a button you will be able to compare the new refraction directly to your previous glasses.  Ultimately the digital phoropter makes the process of “which is better?” less stressful on you.


This advanced device allows Dr. Krishnan to measure each cellular layer in the major structures inside of your eye, including the retina and optic nerve head.  These cross section scans help us detect and monitor diseases in ways not possible with traditional eye exams.


We can directly compare images from year to year. This technology allows us to a wide angle picture of your retina (the back of your eye).
Annual digital retinal exam is very important to detect and follow diseases such as glaucoma, diabetes, macular degeneration, and ocular melanoma.  We can directly compare images from year to year. This technology allows us to a wide angle picture of your retina (the back of your eye).

Dr. Krishnan can check the pressure in your eye without drops or the puff of air.  That’s right, NO PUFF!


Most patients with eye conditions such as Glaucoma do not realize that they might have lost peripheral (side) vision. At Pupila Eyecare we can accurately and efficiently measure your central and peripheral (“side”) vision.

Why is Retinal imaging so important?

With retinal imaging, an ultra-widefield retinal examination, is a revolutionary diagnostic tool that allows clinicians to view a majority of the retina. It uses a non-dilating camera that captures a digital image of the retina. Retinal imaging allows the doctor to capture a 200° high-resolution image of the retina in a single shot-- without dilation -- in a quarter of a second. It’s easy for the patient, takes just a few minutes to perform, and is immediately available for review with the patient in the exam room.

  • You leave the office with vision intact, rather than with light-sensitivity and blur.
  • Creates permanent record.
  • Allows for future comparisons. We can compare this year’s image to next year's image - side by side.
  • Can be reviewed by other doctors, if necessary.
  • It allows for an enlarged image to see a more detailed view of the retina.
  • Early detection of life-threatening diseases like cancer, stroke, and cardiovascular disease.
  • Facilitates early protection from vision impairment or blindness.

Dilation, the traditional method, requires eye drops that enlarge the pupil area and blurs vision for approximately 4 to 6 hours. The drops require 30 minutes to take affect and then another 10 to 15 minutes of evaluation with a bright light source and a magnifying lens. The resulting clinical evaluation is similar to retinal imaging, if the clinician is experienced, patient is cooperative and pupil dilation is maximized. A comprehensive dilation is achieved through 8 to 10 individual inverted views of each retina that is documented on the exam form.
