Till date the best way to correct vision disorders is Lasik laser in which normal vision (6/6) is restored if there is no other eye pathology. With C-lasik, it is now possible to  give a quality of vision, which may be even better than what is achieved with simple Lasik.

Simple Lasik Laser
All vision disorders for which glasses have to be used are measured in terms of sphere or cylinder or a combination of both. The best-corrected vision is termed 6/6. In simple Lasik, the sphere and cylinder power of a person' eye is fed into the memory of the laser machine, and the laser then corrects the error. This means that myopia of -2.0 will be corrected in the same way in all individuals with this error.

C-Lasik Laser:
It is now known that sphere and cylinder constitute about 90-92% of the visual disorders in an optical system of a human eye. The rest is attributed to higher order aberrations. Correction of these aberrations along with the usual spherical and cylinder power of the eye result in a better sharpness and quality of vision. These higher order aberrations along with the usual sphere and cylinder errors can now be measured and documented with the help of a special machine called an aberrometer (OPD scan-Nidek). This machine measures 1440 data points on the eye, records this data in the form of eye maps and the laser beam then corrects these optical errors. Thus C-Lasik is a personalized program and would be different for every eye.

How is C-Lasik performed ?
The surgical steps of C-Lasik are similar to the simple Lasik laser. The optical data of an eye is collected with help of an aberrometer. This data is further processed with a 'final fit' program in another computer and then transferred to the laser machine. The laser machine is equipped with scanning slit and spot delivery system to handle such treatments.
