Nidek OPD Scan II Corneal Topographer
The Nidek OPD Scan II is our corneal topographer. It is used to create a map of the front surface of the cornea. This allows us to diagnose corneal ectasia such as keratoconus, pellucid marginal degeneration, and post-LASIK ectasia. It also allows for more accurate analysis of corneal astigmatism, including the amount, axis, and regularity of it. The corneal topographer is used in conjunction with the Lenstar LS900 for all patients desiring astigmatism correction at the time of cataract surgery. Since the Nidek OPD Scan II is a newer generation machine, it is able to provide intraocular aberrometry to assess for higher order aberrations which can cause visual complaints not correctable with glasses.
