Traditional Lasik Process
LASIK (Laser Assisted In Situ Keratomileusis) involves the creation of corneal flap in combination wit the accuracy of the excimer laser technology to correct the refractive errors – shortsightedness and / or astigmatism by reshaping the cornea so that it’s focusing onto the retina without the use of glasses or contact lenses. |

IntraLASIK
VISTA VISION SPECIALIST is proud to offer IntraLASIK, a form of LASIK procedure made possible by the IntraLase Laser, to our patients. IntraLASIK is a proven, computer-controlled, all-laser technology with the safest, least invasive option in creating the corneal flap. |
|
| |
 |
Prior to the Intralase laser, LASIK’s first step was done manually with an oscillating razor blade, called a microkeratome. This device causes the majority of LASIK complications and can be unpredictable even in skilled hands. |
| |
|
The flap is then lifted to expose the inner cornea for the second step: vision treatment by the excimer laser. |

| |
 |
| The ultra-fast IntraLase FS60TM laser uses an intrared light beam, generating 60,000 pulses per second, to prepare an optimal corneal architecture below the flap. |
| |
 |
Using an “inside-out” process, the IntraLase laser is precisely focused to a point within the cornea, where thousands of microscopic bubbles are formed to define the architecture of the intra corneal surface and the resulting flap. |
| |
|
|
The surgeon controls flap diameter, depth, hinge location and width, and side-cut architecture - factors that can be varied per patient. Bubbles are then stacked along the edge up to the cornealsurface to complete step one.
|
|
|
| |
|
 |
The surgeon then exposes the prepared corneal bed for excimer laser treatment by lifting the flap. The LASIK procedure is complete when the flap is securely repositioned on its beveled edge. |

LASIK is performed on an outpatient basis and takes approximately 15 minutes per eye to perform. Although patients often feel some pressure sensation, the procedure is painless. Topical anesthetic drops are used to numb the eye and an eyelid holder is used to prevent blinking. Patient is asked to focus on a target light throughout the procedure.
MONOVISION LASIK: LASIK Procedure for patients above 38 years old
Everyone is affected by Presbyopia from their 40s onwards, resulting in the need for reading glasses. Monovision is a situation for patients with Presbyopia in which one eye is corrected for near while the other is corrected for distance.
This technique is generally employed for people who desire not to use reading glasses. Contact lenses are used for Monovision correction. Not all patients will adapt to Monovision, as there is a loss of depth perception (since one eye is focused at distance and the other eye is focused at near). Therefore, persons considering Monovision with LASIK should first adapt to Monovision with contact lenses.
