How Photorefractive keratectomy Help in correcting your Vision

The Advancement in Lasik Eye Surgery Treatment

To correct vision, surgeons use lasers to change the shape of the cornea by interfering in the underlying tissue or stromal layer. Currently, this drug includes two very effective types of laser eye surgery: photorefractive keratectomy (PRK) and in-place laser keratomileusis (LASIK).

With photorefractive keratectomy, the doctor manually cleanses the cornea and corrects vision with an excimer laser. Unfortunately, the epithelial layer grows over time, not to mention that the recovery period is longer than with LASIK. On the other hand, the PRK procedure involves fewer risks because the surgeon does not cut the cornea. LASEK (laser-assisted subepithelialKeratomileus) is a new and improved PRK that uses an alcohol solution to soften the area before removing the epithelium. After the excimer laser reforms the stroma, the surgeon replaces the epithelium. With LASEK, the healing process is shorter than with prk surgery in chicago.

Then LASEC became Epi-LASEC. The doctor preserves the living layer of the epithelium using a retractor, and after vision correction with an excimer laser, this layer is replaced. The healing process has become even shorter. On-site laser keratomiliasis or LASIK cuts the corneal fin with a metal microkeratome blade, changes the shape of the eye with an excimer laser, and moves the rib. This procedure immediately corrects vision, and the patient will experience only some blurring over the next 24 hours.

Custom Vue LASIK is almost the same as LASIK, but uses Wavefront software. The technology used is 25% more accurate than any standard method and is used to map the optical system and control the laser to change the stroma. With Custom Intra LASIK, the valve is fabricated using an Intralase femtosecond laser. Then, using the Wavefront manual, an excimer laser corrects visual errors.

In summary

According to experts, this is the most advanced procedure for creating a corneal flap, but, unfortunately, it is also the most expensive.
