LASEK vs LASIK Eye Surgery

02 Jun 2012

The laser eye surgery has been a milestone in the history of medicine. This elective procedure has served many patients across the globe. Technology has been a great help in achieving such modern type of treatment. Laser eye surgery has two types which are LASIK and LASEK surgery.

In choosing which one to undergo, one might be confronted with most common question, "Which is better?"

LASEK vs. LASIK Eye Surgery

LASIK which stands for Laser Assisted in Situ Keratomileusi is a form of corrective surgery which aims to lessen the dependency on contact lenses and glasses. Furthermore, it is a procedure which will correct hyperopia, myopia and astigmatism. An ophthalmologist will perform the procedure using a laser. The cornea will be reshaped so that the visual acuity will improve. The operative procedure would include laser remodelling, flap creation, and repositioning of the flap. According to surveys, between 92 and 98 percent of the patients who had undergone such procedure found it satisfactory. In the year 2008, The American Society of Cataract and Refractive Surgery was able to publish a meta-analysis of patient satisfaction among a sample group of over 3,000 reviewed articles from international clinical journals. The information that dates back up to 10 years revealed that 95.4% of patients were satisfied with LASIK.

Laser epithelial Keratomileusis or LASEK procedure on the other hand is a newer variation of photorefractive keratectomy (PRK). In LASEK procedure, to reshape and correct vision, laser energy is applied directly to the eye's outer surface. LASEK is a hybrid of FDA approved PRK and LASIK. LASEK, on the other hand, has another procedure. The epithelium is kept intact but instead, an alcoholic substance is utilized to weaken the epithelial cells. At this point, the surgeon will proceed to fold the epithelium out of the laser treatment field. He will then put it back in its place once the cornea is shaped by laser.

Both LASIK and LASEK surgery are similar to photorefractive keratectomy (PRK). What differentiates the two procedures is the method in which the inner portion of the cornea is accessed.

The LASIK surgery is known to be less painful, comfortable and has shorter recovery period. Most laser eye surgeries are carried out using LASIK. The procedure is likely to produce 20/20 vision and mostly has the same price with LASEK. LASIK, however, has more risks than LASEK. The complications are mostly related with the creation and recuperation of the flap which protects the cornea.

The LASEK surgery will be avoiding the risks of creating the flap. It also causes dry eye less frequently than LASIK eye surgery. The LASEK surgery, however, has longer recovery period. The patient may feel more pain and discomfort. The side effects may also include cloudy vision and a feeling that a foreign object is in the eye.

A lot of professionals have already researched and wrote about LASIK and LASEK surgery. The procedures certainly have great effects. But along these good effects, each procedure also has disadvantages and side effects. The answer to the question as to which one is better mainly depends on the patient's condition. Hence, it is always best to consult a special
