 The Pentacam images the anterior segment of the eye by a rotating Scheimpflug camera measurement. This rotating process supplies pictures in three dimensions. The center of the cornea is measured very precisely because of this rotational imaging process. The measurement process lasts less than two seconds and minute eye movements are captured and corrected simultaneously. By measuring 25,000 true elevation points, precise representation, repeatability and analysis are guaranteed.
Pentacam is a fast, reliable and accurate instrument that provides important diagnostic information about the cornea and anterior segment of the eye. It is very useful for screening candidates for refractive surgery, as well as for understanding the effects of the surgery on the cornea.
The pachymetric maps are very reproducible and central values correlate very well with ultrasound.
Pentacam also provides valuable information for cataract patients, helping in the decision process trough the optical density measurements, as for IOL power calculations, since it provides more accurate corneal refractive power measurements.
The Oculus Pentacam has become, over the past months, a very important tool for my daily clinical practice.”
The Pentacam is the perfect instrument for refractive patient screening:
- real non-contact pachymetry - better than any
topographic device
- anterior chamber depth - for phakic implants
- corneal topography - exclusion of keratoconus
- white to white measurement.
The Pentacam is today the powerful tool for the objective follow-up of phakic refractive lens implants.
The Pentacam is the first instrument I have seen that provides an
accurate measurement of both the front and back surfaces of the cornea.
With this information we will be able to calculate the true power of the cornea in patients that have had previous refractive surgery. This direct method of measurement will be much better than the historical and contact lens methods we have published previously.
IntraLase®
How the IntraLase Method Works
Unlike mechanical instruments, IntraLase technology is uniquely
able to program the dimensions of your flap based on what’s best
for your eye. Then the IntraLase laser creates your flap from below
the surface of the cornea—without ever cutting it. How?
- Ultra–fast pulses of laser light position microscopic
bubbles at a precise depth determined by your doctor.
- The laser light passes harmlessly through your cornea.
Then the laser creates rows of these bubbles just beneath
your corneal surface as it moves back and forth across your
eye in a uniform plane.
- Next, the IntraLase laser stacks bubbles around your corneal
diameter to create the edges of your flap. These bubbles are
stacked at an angle that is determined by your doctor and is
individualized to the way your eye is shaped.
- The process takes only about 30 seconds from start to finish—
it’s quiet and it’s comfortable.
- Your doctor then gently lifts the flap to allow for the second step
of your LASIK treatment. When treatment is complete, the flap
easily “locks” back into position and rapidly begins to heal.

 Rosenbaum Eye & Laser Center introduced the first scanning excimer laser system to the Mid-Michigan area in August of 2000, our Nidek EC-5000. We are now proud to offer the most advanced technology in laser vision correction, our VISX Star S4™ variable spot scanning excimer delivery system. It features patented 3-D active tracking to allow the patient to relax during the laser procedure while obtaining a precisely centered correction. In addition, our diagnostic WaveScan™ system will map the eye as unique as a fingerprint and guide the excimer laser to design a personalized "custom" laser vision correction., CustomVue™.
VISX laser systems have features that translate into several advantages for you:
How does it work?
The WaveScan system creates a map of the eye, much like a fingerprint, which allows the surgeon to formulate a special treatment plan for each patient. Even though two patients may have the same prescription, their eyes are not the same. The WaveScan's optics project light into the patient's eyes, this visual pathway is then analyzed by thousands of tiny mirrors, thus creating a pattern of vision based on how the light was bent. This pattern of vision is your individual WavePrint, fingerprint of your vision. By having this fingerprint of your vision, the surgeon can better determine your candidacy for laser vision correction.
WaveScan Technology
Originally developed for use in high-powered telescopes to reduce distortions when viewing distant objects in space, the technology has now been applied to laser vision correction, offering a level of measurement that is 25 times more precise than the standard measurements used to determine your eyewear prescription Rosenbaum Eye & Laser now uses this same technology to offer you the state-of-the-art in laser vision correction,
The WaveScan produces a visual representation, or map, of how your eye's own optical system processes light. This map provides a precise and detailed analysis of your eye's unique visual characteristics. Much like your own fingerprint, no two eyes are exactly alike. Your surgeon then uses this analysis to create an individualized treatment plan to correct your eyesight for an optimal visual result. The Wave Scan's digital information is then transferred to the VISX Star S4T Excimer laser system, providing you with an increased level of precision and accuracy
