The Benefits of Femtosecond Lasers and Why We Use Them
Precision, safety, and speed
When it comes to your eyes, there is no such thing as being too careful, especially when you are talking about LASIK eye surgery. A traditional LASIK procedure uses a precise surgical instrument known as a microkeratome to create a thick hinged flap in the eye’s clear surface (cornea). The flap is then lifted, allowing for the application of laser energy to reshape the underlying cornea tissue. The downside of this method is the risk of complications due to human error, flap manipulation, and infection.
However, there is a new bladeless technology out there that uses femtosecond lasers. This new addition to the world of ophthalmology may cost a bit more than traditional LASIK methods, but it provides a variety of benefits that you won’t find anywhere else. Once you take a look at these startling advantages, it’s easy to see why the experts at Spindel Eye Associates choose to use femtosecond lasers.
Significant decrease in complications
Flaps created with a mechanical microkeratome are often associated with cornea complications, such as a detached flap (free cap), a hole in the center (buttonhole), small wrinkles or folds (striae), steep spots (central islands), and infection. The precision and speed of femtosecond lasers have significantly decreased these types of complications, virtually eliminating overly thick flaps, irregular cuts, and trauma induced by manipulation.
The biggest contributor to an increase in patient safety and satisfaction is the speed of the laser, which emits ultrashort optical pulses with a duration well below 1 picosecond. Creating the LASIK flap with a femtosecond laser takes about 10 seconds per eye. Since you, the patient, are under the machine for less time, your eye experiences less trauma. Also, a femtosecond laser allows for an inverted bevel-in side cut, which means the cornea flap can be tucked under instead of pulled back. With virtually no movement to the cornea flap involved, you have a shorter manipulation time and a decreased risk of infection.
Fine tuning allows for increased precision
One common result from mechanical microkeratome LASIK eye surgery is a cornea flap that is cut too thick. This can cause post-LASIK ectasia, a condition where the cornea starts to bulge forward and leads to a deterioration in vision. A femtosecond laser substantially reduces the risk of ectasia because it allows for precise adjustments to the flap’s diameter and the hinge’s placement depending on the patient’s needs, providing consistent results every time. This increase in predictability and consistency has led to a greater percentage of successful outcomes and an improvement in patient safety and satisfaction.

Nearsightedness, a condition that causes people to have trouble seeing faraway objects—while still having excellent vision for nearby objects—is one of the most common types of refractive errors. Being nearsighted can make your life difficult in any number of ways. If you have severe nearsightedness, for example, you may need to wear eyeglasses in order to drive. If your nearsightedness is interfering with your quality of life, laser-assisted in situ keratomileusis (LASIK) may be the solution. LASIK surgery involves using lasers to reshape the cornea of your eye, enabling you to enjoy better vision. The procedure is painless and relatively short, and recovery times are quick. While LASIK may not result in 20/20 vision, it results in significantly improved vision in more than 9 out of 10 cases. If you are interested in learning more about how LASIK could benefit you, visit an eye care center serving Windham and speak to an eye doctor.
If you’re over 40 and planning to visit your vision center near Windham for an eye exam, then you may have questions about how your age can affect your vision. Read on to learn about how age can result in changes in your eyesight.
In Your 40s
While there is a lot that you can do to help preserve the health of your eyes over the years, it’s natural for them to develop signs of aging. When an individual reaches their 40s, a common vision change that they might experience is presbyopia, which refers to a reduced ability to focus the eyes due to a hardening of the lenses. Presbyopia tends to become noticeable when the person is doing close work with small objects or reading. In the early stages of the condition, most people can counteract the effects of presbyopia by adjusting the distance of their reading material, but multifocal contact lenses or reading glasses may be necessary later on.
In Your 50s
Age increases your risk for developing a wide range of diseases, and this includes those of the eye. Some of the common conditions that begin to develop with age include cataracts, macular degeneration, and glaucoma. At this stage in life, it’s important to start monitoring your vision and scheduling regular eye exams. Also, visit your eye care center after being diagnosed with any other health conditions, such as diabetes or hypertension. Glaucoma, in particular, is important to treat in its early stages, so see your eye doctor if you begin experiencing changes in your vision.
In Your 60s
According to eye doctors, everyone would develop cataracts at some point if they lived long enough. Because cataracts are so common among older individuals, it’s considered to be a natural part of the aging process. This disease occurs when small clumps of proteins begin to block light from the eye and reduce a person’s vision. If your cataracts starts to interfere with your daily life, speak to your doctor about cataract surgery. Finally, at this age, it’s important to begin seeing an optometrist annually for eye screenings.
Are you looking for a provider of LASIK near Manchester, Windham, or Derry? If so, then there are several factors that you should consider when choosing a surgeon for your procedure. Consider the following when selecting your LASIK provider :
The Reviews and Surgery Success Rates
One of the most telling ways to identify a high-quality LASIK provider is to look at reviews and to read patient testimonials. Before settling on a doctor, learn about his surgery success rates and how often his patients are satisfied with their results and the care that they received. Also, speak with family, friends, and co-workers who have undergone LASIK, and ask for recommendations for providers.
The Facility and its Technology
As with any medical provider, you should look for a LASIK surgeon whose facility appears clean, tidy, and hygienic. Additionally, learn what technology the surgeon uses to perform the LASIK eye surgery. It is important to find out if the surgeon employs the latest options available when it comes to LASIK treatment to help ensure your treatment’s success and that you get the best possible results. You should note that patients often prefer LASIK that uses 100% all-laser technology, also known as Bladeless LASIK, rather than surgery that involves the use of a microkeratome blade. After doing some research, decide your preference and be sure to pick a provider that offers the type of LASIK that you want.
The Doctor and the Staff
Next, talk to the eye center’s staff. Do they engage you in a friendly and professional manner, as well as answer all of your questions? It is important to find a LASIK eye surgery provider that will listen to your concerns, work with and be understanding of your financial situation, and provide a flexible schedule that suits your own. Finally, ensure that the surgeon is willing to communicate and work with your current eye doctor to help ensure your satisfaction with your surgery’s results.

Are you thinking about getting LASIK surgery and live near Londonderry, Manchester, or Derry, but worry that you may be too old for the procedure? If so, then here is some good news: as long as your eyes are in good condition, then you could be a candidate for LASIK. Read on to learn why you can benefit from LASIK no matter your age.
Your Eye Health
Determining whether you are a candidate for LASIK eye surgery relies more on the state of your eyes than it does on your age. Your eye doctor will ask you questions about your eye health and conduct a thorough eye examination to learn if the procedure would be a safe and effective choice. Candidates for LASIK must have a stable eye prescription, have a history of good eye health, must not have dry eye syndrome, and must pass a corneal thickness test.
Your Overall Health
When you visit your eye doctor to learn about your candidacy for LASIK, he will ask you a series of questions to gain some insight into your lifestyle, how you currently care for your eyes, and your state of health. Some preexisting conditions, such as collagen vascular disease, diabetes, and autoimmune diseases, may affect your candidacy for this procedure. He will ensure that you understand any risks involved with the surgery, and will find out if you have reasonable expectations regarding your results.
Your LASIK Candidacy
To further determine your candidacy for LASIK, your eye doctor will conduct a number of tests and evaluations. During your preoperative evaluation, he will measure your pupil size, as well as the level of nearsightedness, farsightedness, or astigmatism in each eye. Your doctor will also take wavefront measurements, analyze the shape of your cornea, test for dry eyes, measure your corneal thickness, and examine your retina. After conducting this thorough pre-screening, your eye doctor will tell you if this surgery is right for you. If you’re a good candidate for LASIK, then you can benefit from this treatment no matter your age.
Athletes who live in Manchester and those located near Londonderry and Derry might consider LASIK surgery for a variety of reasons. Like other LASIK patients, athletes can benefit from significant improvements in their quality of life. LASIK eye surgery brings freedom from dependency on eyeglasses and contact lenses. For athletes in particular, LASIK eye surgery might help these patients elevate their game to a higher level.
Convenience of Worry-Free Vision
With LASIK eye surgery, there is no longer any need for athletes to worry about complications related to eyeglasses or contact lenses. For example, swimmers simply can’t wear eyeglasses to compete; they must wear contact lenses. Unfortunately, there are several good reasons why the U.S. Food and Drug Administration (FDA) recommended that consumers avoid wearing contact lenses while swimming . Doing so can place these individuals at risk of eye infections and even corneal ulcers. While contact lenses are a good choice for many ophthalmology patients, athletes can benefit from the worry-free convenience offered by LASIK eye surgery.
Possibility of Eye Irritation
Athletes from all different sports activities can benefit from LASIK, not just swimmers. LASIK eliminates the possibility of eye irritation from contact lenses while participating in sports activities. This is a particular area of concern for outdoor athletes, who are exposed to wind, dust, dirt, and similar problems. Wind and airborne pollutants can easily irritate the eyes, especially when the individual is wearing contact lenses.
Risk of Eye Injuries
Some athletes might choose to become LASIK eye surgery patients because they wish to protect their eyes from possible injuries. LASIK can be considered a much safer choice than eyeglasses while playing sports, particularly when there is a possibility that the athlete will fall down or sustain a blow to the face. In these situations, there is always the chance that the eyeglasses will shatter and inflict serious injuries to the eyes that might result in permanent vision loss. After undergoing LASIK eye surgery, athletes can enjoy the peace of mind that comes from knowing that this is no longer a concern.
LASIK treatment can have a significant impact on your life by improving your vision, but not every procedure is right for everyone. If you are considering LASIK eye surgery and live in Derry, Londonderry, or near Manchester, watch this video for tips on determining if this procedure is right for you.
LASIK eye surgery is suitable for patients who are free of eye disease and accept the risks and potential side effects of the procedure. More than 90% of people who undergo LASIK surgery will obtain somewhere between 20/20 and 20/40 vision without corrective glasses or contacts, but candidates for this treatment should feel comfortable with the fact that they may need a second surgery, or that they may need to continue wearing glasses or contacts for certain activities.
If you have vision problems—such as astigmatism, nearsightedness, or farsightedness—your eye doctor may recommend that you undergo LASIK eye surgery near Londonderry, Derry, or Windham . LASIK surgery, or laser eye surgery, is a safe, effective method of correcting vision problems and eliminating or reducing the need for eyeglasses or contact lenses. Here are some signs that you should talk to your optometrist or ophthalmologist about LASIK.
You’re Tired of the Hassle of Contact Lenses or Eyeglasses
One of the primary advantages of LASIK eye surgery is that it can permanently eliminate the need for contact lenses or eyeglasses. This is a financial advantage as well, as once you invest in LASIK surgery, you’ll no longer need to pay for contact lenses, eyeglasses, cleaners, solutions, or accessories. You can also say goodbye to the discomfort of contact lenses or the hassle and aesthetic drawbacks of eyeglasses.
You’re Interested in Permanent Correction of Vision Problems
Wearing eyeglasses or contact lenses will not prevent certain vision problems from getting worse. Nearsightedness, farsightedness, and astigmatism can all become more severe as you age. Older people are also at an increased risk for glaucoma. Undergoing LASIK eye surgery can potentially correct your vision problems permanently. Most people at least experience significant vision correction, while others will never need contact lenses or eyeglasses again. Your eye doctor or ophthalmologist can help you understand your chances of success for complete vision correction and enduring improvements to your vision problems.
You Don’t Have Certain Medical Conditions or Vision Problems
Certain medical conditions and vision problems will increase your risk of complications or reduce your chances of success with LASIK. If you have an autoimmune disease like rheumatoid arthritis, lupus, or HIV, you are not a good candidate for LASIK. Same goes if your eye doctor has diagnosed you with persistent dry eye syndrome. If you have unstable vision problems, or vision that is consistently getting worse, you should not undergo LASIK eye surgery. Laser eye surgery is also not recommended for women who are pregnant or breastfeeding.
Since it first became available, LASIK has undergone many refinements, such as the availability of bladeless surgery. An ophthalmologist located near Londonderry or Manchester can use an IntraLase laser to create the corneal flap, for instance. After creating and lifting the corneal flap, the eye doctor can reshape the cornea and replace the flap. The reshaping of the cornea allows for the correction of refractive errors because light can bend properly as it enters the eye. The three refractive errors that LASIK eye surgery can correct are farsightedness, nearsightedness, and astigmatism.
Eye doctors diagnose patients with farsightedness, or hyperopia, when they can clearly see objects at a distance, but not those that are close to the patients. Hyperopia may occur if the cornea lacks sufficient curvature or if the eyeball is too short. When the light rays enter the eye of a farsighted person, they are focused behind the retina. Patients with farsightedness may suffer from eye strain, achy eyes, and headaches, particularly after close work such as reading or using a computer. They may find themselves holding books and other items further away from the head to compensate.
Patients with nearsightedness have the opposite problem as those with farsightedness. Nearsightedness, or myopia, allows patients to see close objects clearly, but distant objects appear blurry. Myopia is diagnosed in people who have corneas with too much curvature or eyeballs that are too long. Because of the excessive curvature, the light entering the eye is focused on an area directly in front of the retina, instead of on it. Like farsightedness, nearsightedness can cause eye strain, headaches, and fatigue. People may find themselves squinting to see more clearly. They may have trouble seeing road signs or playing sports, but reading is generally easier.
Lastly, LASIK eye surgery can correct astigmatism. It’s not uncommon for a patient to have astigmatism along with farsightedness or nearsightedness. Astigmatism occurs due to the irregular shape of the cornea, which prevents the light rays from focusing properly on the retina. The resultant blurry vision can lead to eye strain and discomfort.
