Laser Eye Surgical procedure Remedies: What Is LASEK? [VIDEO]

On first trying into the opportunity of having Laser Eye Surgical procedure, the quantity of abbreviations and jargon thrown round could be overwhelming, to say the least. However in actuality, there are solely actually three key procedures you must learn about – LASIK, ReLEx SMILE, and LASEK. On this article, we clarify the whole lot you must learn about LASEK, one of many unique Laser Eye procedures that modified the world of refractive surgical procedure for good.

Whereas the method just isn’t used as usually because it was once (the overwhelming majority of Laser Eye Surgical procedure procedures now use LASIK), LASEK continues to be an vital and efficient therapy methodology. It is among the two floor procedures, constructing on the ideas of its predecessor, PRK.

Like all Laser Eye Surgical procedure methods, the elementary precept behind LASEK is the calculated reshaping of the cornea. This methodology modifications the way in which mild is mirrored into the attention, permitting it to settle extra successfully on the retina, subsequently correcting frequent refractive errors similar to myopia (short-sightedness), hyperopia (long-sightedness), astigmatism, and presbyopia.

How Does LASEK Laser Eye Surgical procedure Work?

LASEK, which stands for LASer Epithelial Okeratomileusis, is extraordinarily much like PRK in that each procedures contain eradicating a portion of the floor layer of the cornea (epithelium) to permit entry to the extra everlasting stromal layer beneath. Nevertheless, there are some key variations between the 2 procedures.

Whereas in PRK, an space of epithelium is eliminated utilizing both a microkeratome or a high-precision laser, LASEK includes making use of an alcohol resolution to loosen the highest layer of the epithelium. As Mr. Glenn Carp explains within the video beneath, within the video beneath, this will then be pushed apart, permitting the surgeon to entry the corneal mattress beneath.

Moreover, in PRK, the epithelium which is eliminated is discarded and a protecting contact lens is positioned over the uncovered space. The floor of the cornea will then heal through the restoration interval. In distinction, in LASEK, the surgeon replaces the epithelium again to its unique place. This makes for a lot quicker therapeutic occasions in comparison with PRK as solely the perimeters of the epithelium must to heal.

In all different features, LASEK is similar to PRK and LASIK and follows the identical broad steps:

• The scale and properties of the untreated eye are measured utilizing wavefront evaluation and topographical mapping and thru state-of-the-art diagnostic devices throughout your screening appointment. From these measurements, the exact quantity of LASEK correction is calculated.
• A bit of the epithelial cornea is eliminated and pushed to at least one aspect – permitting it to get replaced in the identical place after surgical procedure.
• The surgeon strikes the part, and an excimer laser sculpts the mattress of the cornea to match the size decided earlier than surgical procedure.
• The surgeon replaces the part of epithelium and locations a protecting contact lens excessive. Inside minutes, pure forces maintain the flap in place, and the LASEK process is full.

Mr Glenn Carp – “LASEK is a process similar to PRK whereby we apply an alcohol base to the floor of the attention.  This loosens the epithelium, the cell layer on the floor of the attention.

“We are able to then push that to at least one aspect exposing the extra everlasting stromal layer beneath, apply a form change with the laser, and we exchange the loosened epithelium again over the floor of the attention. This has been protected and held in place with a bandage contact lens permitting the epithelium from the periphery to exchange the alcohol loosened epithelium over the next 7 to 14 days.”
