1. Precise Measuring: exact measurement of the eye is possible even in cases of high ametropia, pupil size as well as state of accommodation.
2. Non contact Technique: no requirement of local anesthesia, no risk of infection from patient to patient.
3. Saves time: axial length, corneal curvature and anterior chamber depth of the patient's eye are measured on he same instrument saving valuable time.
4. PAM: Gives an estimate of potential vision following cataract surgery. The Potential Acuity Meter (PAM) is a device that is designed to project an eye chart directly onto the retina, in essence bypassing the cloudy lens. For patients with retinal disease, such as age related macular degeneration, the PAM may improve the reliability of anticipated vision following cataract surgery
5. The Super Pinhole device works on a different principle, but may deliver the same result. The patient views a specialized eye chart through a pinhole in an attempt to discover a clearer region in the cataract. Both of these potential acuity measurements may overestimate or underestimate the vision achieved after cataract surgery.
6. Experiencing fading or yellowing of colors
7. If the cloudiness is not near the center of the lens, you may not be aware that you have a cataract.
