INTRACOR Laser Eye Surgery for the treatment of Presbyopia



INTRACOR is a new minimally invasive intrastomal procedure for the correction of presbyopia using TECHNOLAS Femtosecond laser .This Laser is used to reshape the cornea by focusing femtosecond laser beam directly to the middle corneal stromal layer without affecting the superficial corneal epithelium layer or Bowman layer or the deep Descemet’s membrane.

post Intracor Laser Surgery

Reshaping the central part of the cornea changes the refractive power of the cornea. Femtosecond laser beam ablate the mid stromal part of the cornea leading to multiple concentric rings. These rings steepen the curvature of the central zone in the cornea. This central zone can be used for clear near vision. The part of the cornea outside this central zone can maintain clear intermediate and far vision.



Advantages of INTRACOR Laser Eye Surgery

  1. Less risk of infection because these is no wound

  2. Risk of Lasik complications is eliminated. Because the superficial corneal epithelial layer is intact and no corneal flap is created.

  3. Corneal thickness remains unchanged

  4. There is no post-operative pain or discomfort because there is no wound or flap

  5. The cylinder power of the eye showed minimal difference between pre and post operation. Uncorrected and best-corrected distance visual acuities were stable

  6. Time of the procedure is rapid, which lasts almost 20 seconds per eye.


Disadvantages INTRACOR Laser Eye Surgery

  1. All patients reported seeing halos pf lights after the procedure, especially at night and some of them reported that they can’t drive at night. These halos of lights diminished with time over a year.

  2. INTRACOR is not easy to reverse, so patient selection for this procedure is very important. 

  3. For several hours after the procedure, the vision is blurry because of the presence of gas bubbles from ablation of femtosecond laser in the stromal layers of the cornea. Vision clears when the bubbles dissolve after 2 to 3 hours.
