A Guide to LASEK Eye Surgery

LASEK surgery is a form of laser eye surgery that corrects refractive errors by reshaping the cornea – to this day, thousands of people the world over have benefited from this revolutionary procedure. LASEK eye surgery is performed on patients whose corneas are either too thin or too flat for LASIK eye surgery, but both procedures offer the same results in vastly improved vision and negate the need for glasses or contact lenses.

Who Can Benefit From LASEK Eye Surgery?

Patients who suffer from refractive errors will be delighted to learn that LASEK eye surgery can once and for all allow them to live life with more freedom and no longer rely on corrective eyewear.

LASEK eye surgery can be used to treat the following refractive errors:

  • Short-sightedness (myopia) – This eye condition results from the cornea being slightly rounder and shorter than it should be. Due to this, the light that enters the eye converges just in front of the retina, meaning that suffers experience difficulty when trying to see a clear image at a distance. Through LASEK eye surgery, the shape of the cornea is corrected and the light is made to focus precisely on the retina – meaning that the blurred images at a distance will become a thing of the past, eliminating the effects of short-sightedness!
  • Long-sightedness (hyperopia) – Patients who suffer from hyperopia have a cornea that is slightly flatter and shorter than it should be. This results in a blurred image because the light that enters the eye focuses on a point just behind the retina. Most people who suffer from this refractive error rely on glasses on contact lenses, but through LASEK eye surgery, the effects of hyperopia can be permanently corrected. That means no more headaches and straining eyes to get objects – both near and far – into focus.
  • Astigmatism – In this case, the cornea is a more conical shape than it should be – this means that light enters at different angles through this cone. This creates two points of focus and ultimately a blurred image. Although this condition is slightly more complex than myopia or hyperopia, using the right technology, virtually all astigmatism symptoms can be treated through LASEK eye surgery.

What Does the LASEK Procedure Involve?

A patient is deemed an appropriate candidate for LASEK eye surgery when they suffer from one of the above mentioned refractive errors and usually because their cornea is not thick enough to withstand LASIK eye surgery. During the LASEK procedure, an ophthalmic surgeon focuses of the preservation of the corneal epithelium. In this way, the procedure differs from both LASIK and as the surgeon does not create a corneal flap or scrape and remove the epithelium.

LASEK treats the epithelium with a diluted alcohol solution which loosens it; the surgeon then rolls the epithelium tissue back and works with a laser to reshape the exposed corneal tissue beneath. The surgeon then simply smoothly rolls back the epithelium cells in their new reshaped position.

What Happens After Laser Eye Surgery?

Recovery time from LASEK eye surgery tends to take slightly longer than that of LASIK, but in the hands of expert surgeons, the visual outcomes are the same. Patients experience vast vision improvement with maximum convenience.

Post-treatment, patients are usually prescribed medicated eye drops which aid the healing process and relieve any temporary discomfort during this time. For about the first week, patients are given a night shield to wear when sleeping, which prevents any accidental rubbing of the eyes. In some cases, patients are fitted with soft contact lenses to give further protection to the healing eyes.

Patients who undergo LASEK eye surgery will find they have a newfound freedom as they no longer have to rely on glasses or the deal with the hassles of contact lenses or spectacles. Due to their vast visual improvement, many patients say that their self-esteem is boosted, along with their confidence!

Eye Disorders, Please Clap Your Hands

A new therapy comes to people’s eyes, and it is the gospel to people all around the world. This modern technique is called Laser eye surgery, and it receives more and more people’s welcome.

Most of eye disorders are tired of wearing glasses all day long or are bothered with seeing nothing without glasses.

Now these problems can all be settled with the appearance of Laser eye surgery. No matter how deep the degree of your glasses, you can do this surgery.

Laser eye surgery mainly has two types – LASIK and LASEK. The latter is more suitable for those with thin or flat corneas while the case of LASIK is the opposite.

Though the eye surgery is popular among the eye disorders, there is still something the surgery can’t deal with. So you must know the details about the surgery before going to do the operation.

The laser used in the surgery must have been strictly tested. Only those which can cut 0.25 microns of tissue per pulse can be applied to correcting eyesight. Furthermore, you should make sure which area of the cornea is fit for being reshaped.

Not everyone suits for the Laser eye surgery actually. Only the problems of myopia, hyperopia and astigmatism can be corrected well. So if you are in these cases, Laser eye surgery is the best choice, I promise.

You need not to worry about the food that you eat in daily life will affect the result of the surgery, so you can enjoy your food as usual. Ophthalmologist will drip some anesthetic on your eyes before operation, so you will certainly run out of being hurt. However, if you wear contact lenses, you should take them off a week before operation in case the cornea is misshaped. Moreover, people who have the problem of gas permeability need to take off contacts up to four weeks.

Refractive Laser Surgery

Refractive laser surgery is usually performed for correcting common ailments of the eye such as myopia and astigmatism. All refractive surgeries do not employ the use of laser. Some surgeries such as Radial Keratotomy (RK) do not employ laser although they are equally effective in curing refractive ailments of the eye. Some common types of refractive laser eye surgery include Lasik, PRK and LASEK.

Common Method of Refractive Laser Surgery
There are various methods employed for refractive laser eye surgery. These are divided into flab procedures and surface procedures.
* Flap Procedures: In such surgeries, a particular type of blade known as microkeratome is used for cutting a flap in the corneal tissue. The most common example of surgery under this method is called Lasik.
* Surface Procedures: In this process an excimer laser is employed for removing the front portion of the corneal stroma. Unlike the flap method this approach does not require the partial thickness cut in the stroma. Thus differentiating this method of handling the epithelial layer from the flap method. Photorefractive Keratectomy (PRK) and Laser Assisted Sub-Epithelium Keratomileusis (LASEK) are two common examples of surface procedures of refractive laser surgery.     

Examples of Refractive Laser Surgery
Lasik: This acronym stands for Laser Assisted In-Situ Keratomileusis. In this surgery, a flap is cut with the help of microkeratome blade. The thickness of such flap could be between 100 to 180 micrometers. The flap is then lifted and an excimer laser is used to remove the targeted tissues from the corneal stroma. The flap is then replaced after the removal of the unwanted tissues.
IntraLasik is another variant of this surgery. In this method the flap is cut with the help of laser. Where a microkeratome blade is used to create the flap, the proceedure is known as “traditional Lasik” in order to differentiate it from other forms of refractive laser surgery.
PRK: Photorefractive Keratectomy (PRK) was widely used for correcting the vision problems before the popularity of Lasik. In this surgery, the paitents recovery time takes longer than with Lasik.
LASEK: It stands for Laser Assisted Sub-Epithelium Keratomileusis and in this surgery, surface methods is used for correcting the vision problem.

Everything About LASIK Surgery

The most popular eye surgery today is LASIK surgery. It is efficient, fast, very gentle and with few complications. For most people the LASIK surgery can help them no matter if they are nearsighted, farsighted and have astigmatism.

LASIK technique is a further development of the older PRK laser surgery. Both operations are done by removing the outer cornea layer, so the laser can remove the tissue. The difference is that while the PRK eye surgery scrapes the outer layer of the cornea away, the LASIK surgery will cut a flap in the cornea that can bend. After the surgery the flap will be put back again.

The operation itself takes only a few minutes and is completely painless. The eye will be anaesthetized right before the surgery, and most people will not feel any pain at all. Subsequently the flap will be cut and the laser surgery can be made.

The actual operation only takes between 30 seconds and two minutes. A laser specially designed for operating in the eye’s sensitive tissues will be used. After the operation the flap is put back in place.

It is possible to leave the operating room right after the surgery. The eyes may sting a little bit, so it is advised to rest for the rest of the day. A nap can also help.

For most people the sight will have improved right after the operation. It will then stabilize over the next weeks.

After the eye surgery the eyes can feel a little dry. It is therefore recommended to drip them with a little salt water.

All studies indicate that a permanent sight improvement is provided by the LASIK operation. And previous bad eyesight will not return again. But a possible, natural change of sight in the future is not possible to prevent by the operation. So the surgery should not be done before the sight is stable.

The age-related long-sightedness that all people will experience can also not be prevented by a LASIK operation.
