Over the past years, laser eye surgery has gained immense popularity across the globe. It helps people regain normal vision after suffering from various eye problems such as nearsightedness (myopia), farsightedness and astigmatism.
One of the emerging laser eye surgeries today is the Epipolis Laser In Situ Keratomileusis (Epi-LASIK), an updated version of the popular LASIK surgery.
Epi-LASIK combines the benefits from both photorefractive keratectomy (PRK), the first type of laser eye surgery for vision correction, and LASIK (laser-assisted in-situ keratomileusis) procedure.
LASIK vs. Epi-LASIK
According to experts, epi-LASIK eye surgery is safe. Hence, it could be a good alternative to the traditional LASIK surgery.
In Epi-LASIK surgery, the flap created on the cornea is way thinner than the ones done in LASIK surgery. This could be beneficial for patients with thinner corneas. The only difference between the two surgeries is how their flaps are created.
The Epi-LASIK surgery only creates a thin flap and does not pierce into the cornea. In LASIK surgery, however, it infiltrates into the cornea, making Epi-LASIK a safer alternative. Some studies have shown that LASIK surgery sites in the cornea do not fully heal, making blows to the eyes lead to dislodged flap. This could lead to corneal damage that might need a transplant afterwards to regain good sight.
How Does Epi-LASIK Work?
Epi-LASIK surgery entails cutting a very thin flap of tissue from the cornea, a very thin layer of epithelium covering the eyes. The flap is very thin that it prevents penetration of the cornea. After the Epi-LASIK flap is produced, it is creased back and the underlying central stroma will be restructured with the use of an excimer laser, which is also done in the traditional LASIK.
A surgery called excimer laser is an innovative technology for vision correction through surgery. It improves vision and in some people, they often have 20/20 vision after the operation. On the other hand, for those individuals who do not achieve the 20/20 vision after the surgery, they could use extra help from eyeglasses and contact lenses.
Epi-LASIK surgery has become a popular treatment for certain vision problems and since its technology is advanced, fewer complications could occur. Moreover, the recovery time for this type of surgery is shorter compared to traditional surgeries.
