At Collom & Carney Eye Institute vision correction candidates undergo a comprehensive and lengthy evaluation using sophisticated technologies to optimize results and eliminate patients with chances of a poor outcome. By using these state-of-the-art technologies during your evaluation Dr. Northam can determine that your individual needs will be matched to the proper eye procedure that will achieve the safest and best visual outcome for you.
Humphrey Atlas Corneal Topography
A corneal topographer is an instrument that measures the curvature of the front of your eye and creates a kind of “map” of your cornea. No one has a perfectly rounded cornea, and the topographer will display the corneal irregularities and the actual steepness or flatness of the cornea that must be addressed.
Corneal Pachymetry is the process of measuring the thickness of the cornea.
This can be done by using an automated system (which is found on some topographers) and manually. At Collom & Carney Dr. Northam has the ability to check the corneal thickness both manually and automated. This is very important when considering refractive surgery. The corneal thickness will help Dr. Northam determine whether she wants to perform LASIK, PRK or do surgery at all.
CustomVue WaveScan System
WaveScan-based digital technology allows Dr. Northam to detect and measure the optical distortions unique to your entire optical system. By producing a fingerprint of your vision, or WavePrint map, these images will be transferred to theVISX STAR S4 IR excimer laser and used as a guide to reshape the cornea during your laser vision treatment.
The VISX STAR platform’s heritage of dependability and performance is well known. The STAR S4 IR from VISX has taken that reputation to an even higher level. Our latest excimer laser system represents the most advanced laser technology platform available today. Integrating data collected by the WaveScan WaveFront System, the STAR S4 IR utilizes these exclusive VISX technologies to deliver precision custom ablations:
- Iris Registration (IR): The first FDA-approved, fully automated, non-contact method of alignment of the correct CustomVue treatment to the corneal site
- Variable Spot Scanning (VSS): Variable beam sizes from as small as 0.65 mm up to 6.5 mm scanned over the treatment area, conserving tissue and optimizing treatment times
- Variable Repetition Rate (VRR): VRR delivers treatment at varying repetition rates, optimizing treatment time
- ActiveTrak 3-D Active Eye Tracking: Captures all 3 dimensions of intra-operative eye movements—no dilation required
- ActiveTrak Automatic Centering: Locates, and then automatically sets the treatment center to the center of the pupil.
