Ocular Response Analyzer

The Ocu­lar Response Ana­lyz­er (ORA), man­u­fac­tured by Reichert Inc of Buf­fa­lo, NY, is a rev­o­lu­tion­ary device that enables eye doc­tors to mea­sure the bio­me­chan­i­cal tis­sue prop­er­ties of the cornea.

The instru­ment is based on famil­iar glau­co­ma “puff test” tech­nol­o­gy that was invent­ed by Reichert over 35 years ago. This test has tra­di­tion­al­ly been used to mea­sure the eye’s intraoc­u­lar pres­sure (IOP), an impor­tant risk fac­tor for diag­nos­ing and treat­ing the eye dis­ease glau­co­ma. David Luce Ph.D., chief research sci­en­tist at Reichert, dis­cov­ered that this same tech­nol­o­gy could be used to obtain addi­tion­al infor­ma­tion about the eye.

Dur­ing the air-puff mea­sure­ment process, the cornea (the clear out­er lay­er of the eye) moves rapid­ly inward and then back out again. The opti­cal sys­tem of the ORA mon­i­tors this rapid defor­ma­tion, enabling the instru­ment to pro­vide a mea­sure­ment called corneal hys­tere­sis, which is an indi­ca­tion of the vis­co-elas­tic tis­sue prop­er­ties of the cornea. “This new mea­sure­ment gives us infor­ma­tion about the strength char­ac­ter­is­tics of the cornea, which can help us diag­nose corneal patholo­gies and give us a bet­ter abil­i­ty to qual­i­fy can­di­dates for lat­est eye tech­nol­o­gy refrac­tive surgery pro­ce­dures, such as LASIK” accord­ing to Steve Stet­son, MD of Dia­mond Vision. “This tech­nol­o­gy rep­re­sents a major ben­e­fit for sub­jects seek­ing LASIK because it enhances our abil­i­ty to ensure the suc­cess and safe­ty of the pro­ce­dure. In addi­tion, and some­what iron­i­cal­ly” said Dr. Stet­son, “this new mea­sure­ment gives us the abil­i­ty to more accu­rate­ly mea­sure the pres­sure in the eye, the pur­pose for which the instru­ment was orig­i­nal­ly devel­oped for over 35 years ago.”

The ORA at Dia­mond Vision is one of only about 150 such devices installed in the USA. If you are a doc­tor and would like to use the state of the art O.R.A. for your patients, call 888–678-4341.

Oculus Pentacam Camera

The Oculus Pentacam Camera

To make the right deci­sion about LASIK, doc­tors need to have as much infor­ma­tion as pos­si­ble about your eyes. Sophis­ti­cat­ed tests are part of the exten­sive screen­ing per­formed at Dia­mond Vision pri­or to rec­om­mend­ing the surgery. That is how we ensure the best results ever.

Now, out of Ger­many comes the Pen­ta­cam. The Pen­ta­cam con­sists of a cam­era that actu­al­ly rotates to cap­ture images of your cornea from dif­fer­ent angles – some­thing that was impos­si­ble before.

Today, our doc­tors can be even more con­fi­dent in rec­om­mend­ing LASIK to you. As always we ensure that our patients have access to the most up-to-date, world-class vision cor­rec­tion tech­nol­o­gy – at no extra charge.

Iris Registration(IRapproved May, 2005

Goal : Bet­ter vision through a more pre­cise place­ment of the laser beam.

What it does: IR pre­vents any shift in the laser posi­tion­ing that may occur as a result of :

  • The wave­front mea­sure­ments being tak­en while the patient is in a sit­ting posi­tion, ver­sus a lying down posi­tion under the laser
  • Nor­mal eye move­ment before and dur­ing surgery
  • Dif­fi­cul­ty in cen­ter­ing the treat­ment

How it works: Images of the iris are tak­en dur­ing the pre-oper­a­tive exam­i­na­tion. The treat­ment is cen­tered and posi­tioned using the actu­al iris pat­terns of the patient, matched with the pho­tos tak­en at pre-op.


  • Machat (2005): In a study of LASIK patients with astig­ma­tism, 92% of the patients who had IR saw 20/20 three months after surgery, ver­sus 82% among those who did not have IR
  • Koch (2005): One month after PRK, 90% of the patients who had IR achieved 20/20 ver­sus 60.3% of those who did not have IR.

Intralase FS150 upgrade

Goals: Bet­ter vision through a more pre­cise flap cre­ation; a faster, a more com­fort­able pro­ce­dure.

What it does: The FS150 takes the safe­ty and pre­ci­sion of Intralase one step fur­ther with cut­ting edge vision cor­rec­tion tech­nol­o­gy, bring­ing:

  • A faster treat­ment and eas­i­er flap lift, increas­ing com­fort for the patient
  • Min­i­mal dis­rup­tion of corneal archi­tec­ture, stronger flaps, and few­er pos­si­ble com­pli­ca­tions
  • Less tem­po­rary inflam­ma­tion of sur­round­ing tis­sues, for an even faster recov­ery
  • Even more pin­point pre­ci­sion in the for­ma­tion of the corneal flap, for even clear­er vision and fastest visu­al out­comes.

How it works

  • Faster rep­e­ti­tion rate and tighter spot/line sep­a­ra­tion
  • Pre­cise­ly shaped angled edges fit snug­ly to improve align­ment
  • Pro­vides a smooth corneal con­tour with greater sur­face area to speed wound heal­ing
  • Pre­serves corneal inner­va­tion and allows post-oper­a­tive heal­ing by cre­at­ing a bio­me­chan­i­cal­ly sta­ble corneal flap.

Lead­er­ship in laser vision cor­rec­tion

Dia­mond Vision now offers access to com­pre­hen­sive infor­ma­tion com­piled by our laser man­u­fac­tur­er VISX. You can read this infor­ma­tion at any time, but it is espe­cial­ly impor­tant to read it after your pre-oper­a­tive exam­i­na­tion and before the day of your surgery. At your pre-oper­a­tive appoint­ment, the doc­tor will tell you which one of the var­i­ous book­lets bet­ter suits your par­tic­u­lar case.

Note that the same infor­ma­tion applies, whether or not you are hav­ing Intralase. Please use the infor­ma­tion pro­vid­ed by your doc­tor to chose among the fol­low­ing book­lets: Please click here if you need to down­load Adobe Acro­bat to open these doc­u­ments.
If, after brows­ing this infor­ma­tion, you would like to add Cus­tomVue to your pro­ce­dure, call Dia­mond Vision at 888–678-4341, or your LASIK con­sul­tant to ask about adding Cus­tomVue. It would take hun­dreds of pages to describe all the tech­no­log­i­cal inno­va­tions that go into a mod­ern-day LASIK pro­ce­dure, espe­cial­ly after ten years of upgrades and advances.Instead, we will only report here on the very lat­est upgrades and improve­ments, the Ocu­lar Response Ana­lyz­er, the Ocu­lus Pen­ta­cam cam­era, Iris reg­is­tra­tion and the FS60 Intralase upgrade. You can read more about exist­ing tech­nolo­gies in the Pro­ce­dures page. If you have been wait­ing this long to have laser vision cor­rec­tion, why not take advan­tage of the lat­est upgrades at Dia­mond Vision?
