Custom Stable | Aurora

Design

The Custom Stable Aurora is a front surface multifocal, with the same back surface as the Elite, that achieves all of the demanding vision distances of today's presbyopes. It is a design that uses a dominate (distance center)/non-dominate(near center) system that works in unison with the patient and accommodative demands.

Troubleshooting Guide


Objective
Findings Probable Cause Suggested Action
lens rides low too much limbal/central clearance flatten LCZ "+" (100um/step)
vertical meridian of SLZ too flat steepen vertical SLZ "-" 1-2 steps
lens rides high lens too flat steepen LCZ "-" (100um/step)
excessive clearance too steep LCZ lower sagittal depth 1 lens/flatten LCZ
minimal clearance too flat LCZ increase sagittal depth/steepen LCZ
conjunctival prolapse/chelasis too much limbal clearance flatten LCZ (+1 step)
blanching at edges SLZ too steep check location of flat meridian/flatten SLZ accordingly
impingement at elbow too steep of LCZ flatten LCZ (+1 step)
too flat of SLZ flatten LCZ (+1 step) or steepen SLZ (-1 step)
edge liftoff SLZ too flat check location of flat meridian/steepen SLZ accordingly
cloudy after 2 hours or more tear exchange perform NaFl test check location of flat meridian/steepen SLZ accordingly
Subjective
Findings Probable Cause Suggested Action
inadequate near vision excessive decentration see objective guide
too low of add power raise add power on non-dominant eye
too small add zone increase add zone on non-dominant eye
inadequate distance vision excessive decentration see objective guide
too high of add power in D lens lower add power in D lens
too large of near zone in N lens decrease near zone in N lens
too small of distance zone in D lens increase distance zone in D lens
imbalance/non adapt too high of add power lower add power
