Lasek is a technology which is commonly known as a cross between PRK and LASIK. LASEK is basically an abbreviation for Laser Assisted Epithelial Keratomileusis. It applies the technique of LASIK but does so without making use of any flap.
The steps used in the LASEK process are:
1. The eye is numbed by the cataract surgeon using a diluted alcohol solution on the corneal epithelium, which is the outer layer of the cornea.
2. The usage of this alcohol loosens the epithelium from the stroma, which is the central layer of the stroma. The stroma is then removed by the means of a thin cap.
3. After this, a laser known as the Excimer laser is used to sculpt the cornea by the means of an ultraviolet light on the cornea.
4. To help with the healing process, a Bandage contact is placed on the eye. The cap of the epithelial tissues is placed on the cornea to help the Bandage contact lens with the healing.
5. Within just a few days, the epithelial tissues begins to grow and recover. The bandage contact lens are removed after 4-7 days. However, the healing process continues for about a month. Most of the patients have excellent vision by 1 month.
There are many people find themselves confused by the three varying laser eye surgery processes of LASIK, PRK or LASEK. They don’t seem to know the differences between the processes of these different surgeries. Clinical studies have shown that the outcomes arising from these three surgeries within 1 month are almost identical. The only alteration is that with LASIK, the recovery is quick. On the other hand, with PRK and LASEK the recovery is a tad bit slower. However, the cataract surgeries of PRK and LASEK have the added benefit of not having a flap.
