Advanced Diagnostic Testing

Preoperative OPD Wavefront analysis and Corneal TopographyOPD1

The OPD is an advanced form of corneal topography which assesses the health of the eye structures responsible for your visual focus. It analyzes your whole visual system and measures possible distortion from dry eye or previous eye surgery or astigmatism. It can also evaluate which refractive lens implant might be best for your eye. After surgery, the OPD provides assistance in diagnosing problems with visual focus to aid in surgical enhancement.


Cassini point-to-point Total Corneal Astigmatic analysis                                                      Cassini Platform 1

The Cassini topographer provides our surgeons with further details specific to your cornea. This topographer has a unique measuring guide that detects astigmatic imperfections in the front and back of your cornea which may otherwise go undetected. When untreated, astigmatism will remain post-operatively causing visual distortion. With one quick test, the Cassini topographer moves your surgery one step closer to perfection.



Pentacam1Pentacam imaging of the anterior segment of the eye

The Pentacam supplies a detailed analysis of all eye structures in the anterior chamber, or front of the eye. This provides the surgeon with additional measurements to determine the true total corneal refractive power and corneal thickness. Also, by sending light through the pupil the Pentacam presents a precise snap shot of the natural lens and degree of the cataract. It can also be used as a tool for detection of corneal diseases such as keratoconus.


Zeiss Humphrey IOL MasterIOLM

The Zeiss Humphrey IOL Master is a key component to choosing the most accurate lens implant for all cataract sugeries. It provides the surgeon with measurements of eye length and corneal curvature which is crucial in determining the appropriate lens implant power.


ORA2Advanced Intraocular Lens Calculations (especially for previous LASIK patients)

The standard measurements taken for the calculation of lens implants with cataract surgery are not accurate in patients who have had previous refractive surgery such as LASIK or PRK. At Eyes of York, we employ multiple advanced methods of lens implant calculations. Your surgeon will tailor your calculation based on any previous eye history data and use sophisticated new technology measurements adjusted with modern formulas. Finally, we use intraoperative wavefront technology called ORA Optiplus which will provide real time intraoperative measurements for lens implant accuracy selection during surgery.


OCT evaluation of the retinaOCT

The Optical Coherence Tomography (OCT) for the retina provides an extensive scan of the posterior segment, or back of the eye. This helps to rule out or identify possible abnormalities or diseases that are not visible during a standard dilated exam. Certain posterior segment diseases are incompatible with specific lens implant choices. The information provided by a retinal OCT is vital in deciding the proper refractive technology to maximize the personal best vision.
