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!

Non-prescription and prescription eyeglasses

Eyeglasses of all types can be divided into two groups according to the function of their lenses. One main group is prescription eyeglasses, which are equipped with lenses with a power or certain powers. The other basic group is non-prescription eyeglasses. It is absolutely true that there are many ways to categorize the numerous spectacles produced by different manufacturers in the world. But lens power is one of the simplest approaches to such a classification. Eyeglasses in old days were all prescription ones because those wearers resorted to these devices solely for vision correction. Non-prescription eyeglasses are now available and popular in modern days. The emergence of non-prescription spectacles suggests that there are urgent needs from certain individuals to decorate their eyes. This is best testified by the prevalence of fashionable sunglasses. While non-prescription glasses are being enjoyed by more and more people who never need vision correction, prescription eyeglasses are still indispensible for those with defected eyesight.

In general, eyeglass users can buy a pair of prescription eyeglasses only when he or she has gained a valid prescription of the eyes. Such kind of eyeglass prescriptions can be determined by an eye doctor, either an optometrist or an ophthalmologist. An eye optician only has the right to provide eyeglasses according to a prescription given by an eye doctor. This is a strict requirement which is aimed to ensure eye safety for those wearers. In a serious case, an improper or out-of-date prescription may impair the wearer’s eyes. Prescription eyeglasses will help the eyes refocus the entering eyes appropriately, which is called “correction” in brief. But a basis point is that such kind of correction can be precise only when the eyeglass lenses have the right power according to the wearer’s eye condition. In a traditional way, most people trust eye doctors or practitioners when they want to buy prescription eyeglasses due to security concerns. In fact, other sources especially online eyewear stores can also provide safe prescription glasses. They can offer spectacles with vision correction exactly according to the prescriptions submitted by customers.

Dissimilar to prescription eyeglasses, non-prescription spectacles are designed to meet the needs for fashion. Many ordinary individuals and celebrities choose to wear designer sunglasses in summer days. Modern types of non-prescription eyeglasses usually incorporate the cut-edge fashionable tastes. Semi-frame and frameless eyeglasses are both stylish. In addition to special frame styles, non-prescription eyeglasses can also take use of unusual colored lenses. In some cases, those slightly tinted lenses can create an attractive effect. In a word, stylish elements are the key contributor to non-prescription glasses.

Astigmatism

If you have blurred vision when looking at objects up close, far away, and in between, it may be astigmatism. Astigmatism causes blurry vision due to an irregularly shaped cornea. Most people have some slight astigmatism but not always enough to cause vision problems.

Your Cornea and Astigmatism

Astigmatism is a type of refractive error. Your cornea bends, or refracts, light as it enters your eye to focus it on the retina. In order to properly focus the light, your eye needs to be spherical in shape. With astigmatism, the cornea is oblong or oval shaped, more like a football. When the irregularly shaped cornea bends the light it creates two or more focal points, rather than one clear focal point, causing the image to be blurry.

Recognizing Astigmatism

Astigmatism can occur alone or in combination with nearsightedness (myopia) or farsightedness (hyperopia). Symptoms include:

Children can be born with astigmatism, or the condition can be caused by trauma to the eye due to an injury or surgery. Keratoconus is a disease of the eye that causes progressive thinning of the cornea and can cause astigmatism.

If you are experiencing the symptoms of astigmatism or any change in your vision, it is important to see your ophthalmologist right away. These can be symptoms of a more serious eye condition or health problem.

Astigmatism in One Eye

When vision is different between your two eyes, your brain chooses the better of the two images, ignoring the bad eye. The eyes do not work together properly and depth perception is affected.

In young children, whose brains are still developing, astigmatism in just one eye can cause lazy eye (amblyopia). Left untreated amblyopia can cause permanent vision loss in the affected eye.

Correcting Astigmatism

Eyeglasses or contact lenses are typically prescribed for people with astigmatism. In the past, soft contact lenses were not an option for astigmatism. Today there are soft contacts available for astigmatism, but they are more difficult to make and cost more than other soft lenses.

Corrective lenses improve your vision while you wear them, but they do not truly correct the astigmatism. Refractive surgery, such as LASIK or PRK, reshapes your cornea correcting the refractive error. If you are also nearsighted or farsighted, the surgery can correct that at the same time, giving you clear vision without the need for glasses or contacts.

If you are struggling with blurry vision, headaches, or eyestrain, please visit Eyes.com to learn more about the causes and solutions.
