How Lasik Eye Surgery Works?

Thursday, August 4th, 2011

If you want to enhance your vision in order to enable you to see properly without having to use your glasses or eye contacts, then believe me when I tell you that there is a way out. There is a type of surgery referred to as LASIK which can help you to achieve this aim.Photorefractive keratectomy (PFK), Radial keratomy and Lasik vision surgery are all current procedures but the medical experts consider the latter as being the most affordable and fastest one.

After a Lasik vision surgery, 99% of the patients don’t need their glasses anymore while the same percent is used to determine the visual acuity. This type of surgery is a delicate mixture of laser treatment and surgical procedures.

At first the surgeon creates a flap and lifts it to one side so that he can use the laser to reshape the cornea. There are a few risks involved here because the major optical function of the eye is altered by this refractive surgery.

That’s why it’s very important that your surgeon explains you all the risks and complications, the side effects and also the limitations of this procedure.

Lasik vision surgery won’t interfere with your eye’s aging process. If you choose to have this procedure because of occupational vision requirements then there’s a big chance that both you and your boss will be pleased with the results.

In order to be a good candidate for the surgery, the patient must be at least 18 years old and must have a normal corneal structure. Also, before the procedure the lenses are strictly forbidden (3 weeks for soft lenses and 4 weeks for hard ones).

The procedure is not performed on patients that suffer from any condition that can affect the corneal wound healing (immunosuppression, corticosteroid use, etc.) or on patients that have untreated superficial eye disease.

Diagnostic Overview

An improvement over PRK, Laser-assisted In Situ Keratomileusis removes a stromal layer by flattening the curvature of the cornea. Using a microkeratome, the doctor creates a corneal flap and retracts this tissue less than 1/3 of the thickness of a human hair in order to access the corneal stroma and use the excalculated measurements.

Next, he rolls back and repositions the corneal flap.

Lasik surgery provided great results in correcting residual myopia that usually appears after cataract surgery. It is safe (safer than PRK), stable and predictable, it causes less post-op discomfort and involves only a few minor side effects.

Not to mention that after the surgery, the patient has no corneal haze and there’s no need for complicated postoperative care. Even so, you should be aware that any complications are more severe than the ones with PRK because the laser works on a deeper level of the cornea.

After Lasik vision surgery, the DLK must be taken into consideration because this is a non-infectious, peculiar and inflammatory reaction in the lamellar interface.

To be more precise, for a multi-factorial cause in the first week after the surgery may occur a diffuse, white, culture-negative, granular lemellar keratitis.
