A Little Bit About LASIK Surgery

LASIK surgery which is short for laser-assisted in situ keratomileusis is a procedure used to correct unclear vision. It is also referred to as laser vision correction. This correction surgery is used in the treatment of hyperopia (farsightedness), myopia (nearsightedness) and astigmatism. The eye’s cornea is shaped during this surgery to enable the penetration of light into the eye.

Excimer lasers form a fundamental part in the laser eye surgery technology. These lasers are computer-controlled to guarantee the correction of specific vision errors of patients. Automatic eye-tracking systems are used in to ensure that the UV light beams are always on target.

Wavefront LASIK is the other technology that is used for vision correction. It enables the personalization of one’s treatment to suit his or her ideal vision. A computer image is used as a guide during this process. This technology offers a higher chance of the achievement of 20/20 and better vision.

LASIK is considered to be incredibly beneficial. However, not all patients who desire this procedure are ideal surgical candidates. An ideal candidate is required to have sufficient thickness within his or her cornea for this surgery. A thin cornea may compromise results leading to vision impairment. A stable prescription for eyeglass for at least 2 years is also required. For more information contact Dr. Stanley Crews in Portland, Oregon.

Pupils should also not be too large. Large pupils risk side effects such as glares, starbursts, and halos in low light. One should also be old enough (21 years) for this procedure to be performed. Healthy eyes and a healthy body are other requirements for an ideal candidate.

The costs of LASIK vary. They vary from about 1000 to 3000 US dollars per eye. These costs may include presurgical care, post-operative care, and examinations. They may also include follow-up surgeries.

The actual procedure involved in LASIK usually takes less than 10 minutes for each eye. This is dependent on your prescription and the correction needed. The laser may only take about 30 to 50 seconds to correct one’s vision.

LASIK patients recovery times vary. Most patients report vision improvements within the first 2 days. Some may take between 2 to 7 days to recover. However, full recovery may take at least 6 months.

Patients who undergo LASIK eye surgery may experience various side effects. Dryness of eyes may be experienced after the completion of this surgery. Discomfort may also be experienced during the first 24 to 48 hours of surgery completion.

Halos around images, glare, fluctuating vision and difficulty during night driving may also be experienced by some patients of this surgery. A decrease in tears may also occur. Risks of vision loss may also be experienced but in very rare cases.

One should expect eyes to itch or burn after this vision correction surgery. Discomfort and pain should also be expected. Sensitivity to light, starbursts, glare, and haloes may also be experienced. Additionally, eyes may be teary or water after this procedure.

LASIK eye surgery can help in the correction of vision. This is achieved by lasers that are used in reshaping one’s cornea. Care should be taken after this procedure to avoid injuries by constant rubbing of eyes. This procedure helps in vision correction and restoration.

The Benefits Of LASIK When Compared To Wearing Contacts Or Glasses

LASIK surgery is one of the best forms of eye correction. If you are tired of wearing glasses or contacts, it is easily one of the best options that you can consider. It offers a variety of benefits to the average person in need of corrective eye solutions. Below, we will be going over some of the clear-cut benefits of getting LASIK surgery.

Benefits Of LASIK:

1. Save Money.

One of the main issues associated with wearing glasses or contacts is the fact that it can be very expensive. Getting a new pair of glasses after your previous pair gets damaged or having to replace contacts daily can get very expensive, to say the least. In fact, the estimated cost of contacts is well over $300 per year. While LASIK surgery is certainly much more expensive, when you factor in the cost of contacts over the course of several years, it quickly becomes the much more affordable option. Thus, having LASIK surgery has a much quicker break-even point than you might think. Once you reach that point, the total amount of time you can go without buying new contacts or glasses is only going to save you money. Therefore, if you are looking for cost savings over a long period of time, LASIK is capable of doing just that.

2. Convenience and Comfort.

Another benefit of getting LASIK surgery over wearing contacts or glasses daily is the pure convenience of not having to worry about bringing something with you or putting your contacts or glasses on. Because you will be able to see clearly without having any sort of eye correction solution on your eyes or face, you will be able to go about your daily life without ever having to worry about forgetting your glasses or contacts or worrying about them breaking during physical activities.

3. Improved Vision.

LASIK has such a good track record of success that it can be an excellent option to improve your vision even beyond what you will be able to get with glasses. For those that are either near or farsighted, you are likely going to have to deal with inconsistencies with your prescription and your everyday life. With LASIK, you don’t have that same issue to deal with.

4. Long-Lasting Results.

With glasses or contacts, you are generally going to have to get a new prescription every few years or so. With LASIK, you are generally going to be able to avoid having to worry about your vision for a long period of time. The results that you are able to achieve with LASIK are long-lasting. The results that you get from LASIK are expected to be permanent and the improved eyesight that you get from the procedure is expected to remain with slight reductions based on the normal eye aging process.

Overall, there are plenty of benefits that you can get from getting LASIK rather than relying on contacts and glasses. Not only will it save you money over the long term, but it can offer improved vision and added convenience to your daily life.

LASIK vs. PRK Eye Surgery

With the cultural growth of those interested in having the LASIK procedure performed on their eyes, many have forgotten that there are other surgical options available, including the original vision of LASIK, called PRK, or photorefractive keratectomy. Prior to LASIK, PRK was the most common laser surgery performed on the eyes. Following are a few of the similarities and differences between LASIK and PRK, which is still performed and preferred by some surgeons:

The corneal flap: The creation of the corneal flap is the main difference between LASIK and PRK. In the PRK procedure, no flap is created. Instead, a blade cuts a flap in the cornea, and alcohol is used to scrape it off the surface of the eye so only the area to be resurfaced is exposed. This may be more appropriate for those with thinner corneas. The LASIK procedure utilizes the creation of the flap as a natural “Band-Aid” to place over the resurfaced cornea when the procedure is completed. The thought is that this increases healing time and reduces complications such as infections on the corneal. Indeed, those who have the PRK procedure take longer to heal than those who opt for LASIK.

The excimer laser: The excimer laser is the ultraviolet laser that gently removes cells off the surface of the cornea, resulting in a reshaping of the surface of the eye. The laser works by tiny pulses of bright, cool light. Both PRK and LASIK are performed by using excimer lasers to resurface the cornea. However, PRK uses a microkeratome, which uses a blade to cut the flap of the cornea off. LASIK procedures may be performed using a microkeratome, or the new “all laser” technique that uses a laser to cut the flap.

Treatment for myopia, hyperopia, and astigmatism: Both PRK and LASIK allow for the treatment of far-sightedness (hyperopia), nearsightedness (myopia), and astigmatism. Since the procedures both resurface the cornea by using gentle pulses of laser light, the end result of each is similar.

Time required: Both procedures are outpatient and ambulatory, meaning you walk out shortly after the surgery is complete. The procedures take only a few minutes on each eye, and while the surgery may last an hour or so for both eyes, most of the time is spent preparing the surface for ablation.

After surgery and follow up care: Since the patient is given a mild sedative prior to each procedure, he or she will need a ride home from the surgeon’s office. In both LASIK and PRK, eyesight will be hazy and distorted for the first few days following surgery. In each instance, the patient will need to see the surgeon for a follow up visit 24-48 hours following the procedure. In the case of PRK, healing time is extended, and additional follow up visits may be required until visual acuity has stabilized.

As you can see, there are very few differences between the LASIK procedure and PRK. The major difference is the creation of the corneal flap, which can create a safe healing environment for the eye, but can also be the cause of many possible complications. Because of the risks involved with cutting and having a corneal flap, military personnel and many airline employees are advised to avoid laser surgery on the eye, and choose PRK over LASIK if necessary.
