Epi lasik surgery is a latest laser eye operation method that was urbanized to get to the bottom of a few of the possible difficulties with Lasik and Lasek. Epi lasik surgery is a type of a cross between the two, but varies in some key regions.
Lasik occupies cutting a flap with either a laser or a sharp blade; with Epi lasik surgery as well comes the risk of cutting the flap too thickly.
Lasek occupies cutting the cornea’s outside layer, the epithelium, in a thin sheet that keeps its axis on the eye. This is complete in Epi lasik surgery too, but the doctor utilizes a rounded, plastic oscillating blade in its place of LASEK's finer blade as well, in its place of the alcohol that is utilized in Lasek to untie the epithelial sheet, in Epi lasik surgery the doctor utilizes the plastic blade, known as an epithelial separator, to divide the sheet from the eye. This evades the risk of a effect from the alcohol, which can kill epithelial cells.
Since it is additional not easy to make the epithelial flap in people with steeper corneas (who have advanced amounts of myopia), the process is additionally suitable for people with fewer steep corneas (who have low myopia).
After the epithelial flap is prepared, it is lifted and softly folded out of the way. An excimer laser is utilized, as in Lasik or PRK, to shape the essential corneal tissue. Then the epithelial flap is placed back on the eye with a type of spatula. A unique contact lens is placed on the eye to keep the flap in place while it re-epithelializes. Surgeons use a high-Dk contact lens for this, which means it is extremely oxygen-permeable. The contact lens defends the outside of the eye and lets the epithelial cells to rise back correctly.
If you have Epi lasik surgery you will probable suffer a few pain, which is controllable with over-the-counter painkillers. The ache is allegedly less than with PRK or Lasek.
After Epi Lasik Surgery
By about the third day after Epi Lasik Surgery re-epithelialization has happened, therefore the surgeon may allow you to eliminate the contact lenses.
Who Can Have Epi Lasik Surgery
If you are bearing in mind Lasik, but your surgeon says you require Epi Lasik Surgery as an alternative. Ask why.
Epi lasik surgery is not for everybody, but a lot of doctors who execute Epi lasik surgery think it a improved alternative for a few patients who will possibly not do extremely well with Lasik. These consist of people who have thin corneas, with not sufficient tissue for an excellent lasik flap.
