LASIK is Laser Assisted In-situ Keratomileusis,a procedure to make one independent of the use of corrective glasses.Here the cornea is restructured so that light focuses on the retina without the aid of glasses. There are two steps in the LASIK procedure.First,a microthin flap is created and lifted to open up the surface of the cornea for the second step which is tissue ablation (restructuring) by an excimer laser.

The first step is done either by an ultrathin blade called the microkeratome (regular/Blade LASIK) or with laser (Blade Free LASIK)

The Femto Second Laser introduced the concept of Blade -Free LASIK,thereby refining the first step.It has made the procedure more safe,more comfortable ,more predictable with significantly better visual results.In the USA,more than 25 percent of all LASIK procedures are done by this technique.

NASA has approved Blade-free LASIK for the correction of refractive errors.

The Medical Director is involved with the selection,assessment and management of all clients who would want to undergo the procedure.LASIK is conducted at an associate center  by the Medical Director herself.

The LASIK is done on the AMARIS 500Hz Excimer Laser,

BLADE-free LASIK is done with the FEMTO LASER Z4.

PRESBYMAX is the latest treatment for the correction of presbyopia.Presbyopia is the age related blurring of near vision after the age of 40 years.Earlier correction of distance and near vision was a challenge but now with the introduction of PRESBYMAX,it has become easier to correct near,intermediate and near vision with a high quality.

PRESBYMAX is a good option for patients who have undergone LASIK earlier or for those who have undergone cataract surgery and have monofocal lenses and now aspire for glass free near vision too.

THE LASIK PROCEDURE:

Its an “inside-out” process, wherein the FS laser is precisely focused to a point within the cornea, where thousands of microscopic bubbles are formed to define the architecture of the intracorneal surface and the resulting flap.

The diameter, depth, hinge location and width, and side-cut architecture — factors that can be customized as per the requirement of the individual patient and can be controlled by the surgeon. Bubbles are then stacked along the edge up to the corneal surface to complete step one.

The surgeon then lifts the flap to expose  the corneal bed for excimer laser treatment. The LASIK procedure is complete when the flap is securely repositioned on its beveled edge.

All other Refractive Surgical Procedures like Refractive Lens Exchange and PRELEX will be conducted at the Center itself. The Center, however, also has a long term proposal for acquiring the LASIK facility.
