Corneal imaging is a critical part of the workup for refractive surgery.

Corneal imaging creates a 3-dimensional model of the cornea which is useful for examining important parameters such as corneal curvature, power and thickness. It is used to diagnose and monitor various diseases of the cornea, the most important of which is keratoconus. It is a non-invasive, non-contact procedure which takes approximately 5-10 minutes to perform and the results are available immediately. 

Corneal imaging is a critical part of the workup for refractive surgery. It allows the ophthalmologist to decide on the most appropriate type of surgery and to create a treatment plan which will give the best visual outcomes with the highest safety profile. It is also routinely performed as part of the workup for cataract surgery to precisely map the magnitude and direction of corneal astigmatism. The ophthalmologist can use this data to correct astigmatism at the time of cataract surgery. This can be done by using special intraocular lenses or by surgically manipulating the cornea.
