Lasik stands for laser assisted in-situ keratomileusis. It is widely considered as the procedure of choice for correction of most cases of myopia. Lasik sometimes is called the “flap and zap” procedure. It combines an established cutting technique using a cutting device called the microkeratome with the more recently developed excimer laser technique. First a circular superficial cornea flap is made with the help of the mircokeratome. Next the flap is folded back to allow the excimer laser to reshape the deeper layers of the cornea according to the patient’s spectacles prescription. The flap is then folded back and will adhere itself naturally without the need for stitches.

Nidek Final Fit Software
Nidek Final Fit Software was created to evaluate data from the OPD-Scan to determine the Customised Ablations parameters. The software converts data from the individual refractive maps into sphere, cylinder and irregular components that create the total ablation profile needed to produce the precise customised ablation parameters for the patient eye. Final Fit Software is aimed to ensure the surgery corrects the cornea shape and the aberrations. The resulting data is then transferred to the EC-5000 for the refractive surgery procedure.
Active Eye Tracker System
It utilises high-speed digital video camera technology to follow the patient eye to ensure the laser alignment during the procedure. This is closed loop system, which will track the eye movement independent of hydration or shape changes during surgery.
Multipoint Segmental Ablation
The Multipoint Segmental Ablation System divides the rectangular-shaped laser beam into six small equal segments, which can be individually or simultaneously projected onto the cornea for a more efficient treatment. The Multipoint Segmental Ablation System enables the EC-5000 to direct the Excimer laser beam to smaller, more specific areas on the corneal surface requiring additional treatment to compensate for irregularities and aberrations of the eye.
