Laser Eye Surgery and the Epithelium
Overview
Laser eye surgery, often referred to as ophthalmic surgery, involves procedures performed on the eye or its surrounding areas. Due to its delicate nature, this surgery is typically conducted by an ophthalmologist, which is why it's originally named ophthalmic surgery.
Common Types of Laser Eye Surgery
There are several types of eye surgeries, with some of the most common ones detailed below:
PRK (PhotoRefractive Keratectomy)
PRK involves the manual removal of the outermost layer of the cornea, followed by reshaping the underlying tissue with an excimer laser. After the procedure, the outer layer has to regenerate to protect the eye. Due to this, PRK tends to have a longer recovery time. Despite advancements that use lasers to vaporize the epithelium, this method is not widely adopted.
LASEK (Laser Assisted Sub-Epithelial Keratomileusis)
LASEK is an advanced form of PRK and involves the application of an alcoholic solution to soften the epithelium before its removal. This allows the epithelium to be repositioned after surgery.
Epi-LASEK
Epi-LASEK is similar to LASEK but uses a barrier to retain the epithelium layer, which is then replaced after surgery. This step aims to reduce post-surgery discomfort and speed up recovery.
Conclusion
As you can see, there are multiple methods of laser eye surgery, and these are just a few options available. If you're considering eye surgery or want more information, it’s advisable to consult with your local physician and eye specialist.
